How to make your teeth white. Everything you need to know about teeth whitening. Honey, oil and apple cider vinegar

Currently, there are several methods that can make teeth white. Some will require considerable financial expenses associated with a visit to the dentist, while others are available at home.

Professional teeth whitening

You can change the color of the enamel using the services of a dental clinic. Nowadays, most of them can offer several whitening methods. The choice will depend on the sensitivity and texture of your teeth, as well as your overall oral health. After inspection, experienced specialists will be able to select the most suitable option. There are the following types of teeth whitening in dentistry.

Zoom system

This method is based on the use of a gel containing calcium phosphate, which strengthens the enamel. Under the influence of light rays, oxygen molecules are released and remove all types of tooth pigmentation.

This system involves several sessions, depending on the persistence of pigment spots on the tooth. And the advanced Zoom 3 whitening system can do this quickly (by 8 shades in one visit to the dental office). If all recommendations are followed, the results of this procedure will last for a long time.

Laser system

A whitening gel is applied to the teeth, which is activated under the influence of ultraviolet lamps (laser). This procedure not only makes teeth white, but also serves as a preventive measure against caries. Each visit to the dentist to whiten teeth with a laser enhances the initial effect.

Air flow system

This is teeth cleaning with a jet of powder, which contains soda and silicon dioxide.

How to make teeth whiter at home?

Hydrogen peroxide

You can always find a bottle of peroxide in your medicine cabinet at home. Using gauze or a medical bandage, it should be applied to the teeth and left for 2 minutes. This procedure will make them whiter. However, do not overuse it: frequent use of peroxide can damage the enamel.

Regular lemon

Its juice eats away plaque and returns teeth to their natural color. It is enough to occasionally rub your teeth with lemon peel. However, its frequent use, like hydrogen peroxide, can have a detrimental effect on the condition of tooth enamel. If plaque is not the only problem, and tartar is preventing a beautiful smile, you can restore healthy whiteness to your teeth at home using lemon juice mixed with table salt.

Common vegetables

Carrots, broccoli, radishes, celery and cucumber can cleanse teeth of plaque and age spots. By consuming these products, you can not only whiten your teeth without harming them, but also get a portion of vitamins that have a beneficial effect on the general condition of the body.

Wood ash

This remedy has long been forgotten, but in vain, because its properties were used even before the advent of toothpastes and professional whitening systems. The thing is that ash contains potassium hydroxide, which is a natural teeth whitener.

Dairy products

According to dentists, the lactic acid contained in such products prevents the destruction of tooth enamel and promotes whitening.

Strawberry

When it comes to teeth whitening with folk remedies, juicy strawberries cannot be ignored. You need to eat it as often as possible.

How to do without bleaching?

In order to avoid bleaching, it is necessary to limit the consumption of coloring drinks and foods. These include:

  • coffee, strong tea, carbonated drinks with dyes, red wine;
  • blueberries, blackberries;
  • mustard.

Smoking has a detrimental effect not only on human organs, but also on the shade of tooth enamel. Some time after giving up this bad habit, your teeth will become noticeably lighter.

The main condition for maintaining healthy and white teeth is proper regular care. Remember to brush your teeth twice a day.

Best Teeth Whitening

“In pursuit of the perfect white color, patients sometimes forget about naturalness. Teeth look natural when the color of the teeth matches and harmonizes with color of the whites of the eyes. Teeth that are too white can even look like dentures, which, naturally, does not look good on anyone. Therefore, the first thing you should decide is what is the maximum possible level of “whiteness” in your case.

If you are nevertheless not satisfied with the color of your teeth, then you need to figure out what is causing the darkening. Their color is largely determined by the color of dentin; depending on the structure of the enamel, dentin “shines through” to a greater or lesser extent. Sometimes you can whiten the enamel, but in some cases it is very thin or its structure is changed, then only veneers or crowns will help. In addition to genetic factors (enamel and dentin structure), coffee and tobacco play an important role: they change the color of teeth.

Whitening is a chemical and/or physical effect on the hard tissues of teeth, resulting in a change in color.

Popular

Before whitening, it is very important to carry out professional oral hygiene and remove all supra- and subgingival dental plaque. It is very important that your teeth are healthy: there are no caries and its complications. Keep in mind that only the tooth tissue is whitened; if the tooth has fillings, they will remain the same color and may need to be replaced. It is also impossible to bleach veneers, crowns, and bridges.

Whitening can be done in the office or at home. With in-office whitening, the entire procedure is performed in the dentist's chair. In one visit, you can achieve the result of lightening the color of your teeth by 1-4 shades. It is important to understand that the result of whitening greatly depends on the structure of the enamel of your teeth. In office whitening, chemical whitening systems, laser, and photobleaching are used. There are two types of in-office bleaching: in the first case, the reaction is triggered by mixing two chemicals, in the second, it is initiated under the influence of special lamps or a laser. It should be noted that the second option is more expensive, but more effective, since the teeth are lightened by a greater number of tones. It usually takes one to three in-office whitening sessions to achieve the desired results.

Home whitening is practiced as an independent procedure, and is also often a continuation of office whitening. In this case, bleaching reagents of lower concentration are used. Individual trays are made in advance and the gel is poured into them. The dentist prescribes the number of applications and duration of procedures.

In pharmacies and stores there are also various products for teeth whitening: pastes, gels, strips. Before use, I recommend consulting with your doctor. Improper use of abrasive pastes can cause increased tooth sensitivity, and whitening strips and gels can damage the oral mucosa and cause microflora imbalance.

When whitening teeth, either urea-peroxide systems (less traumatic for enamel) or peroxide systems are used - in various concentrations. Discoloration of the enamel occurs due to chemical exposure. Laser and light are the catalyst for this chemical action. Laser whitening is carried out due to the bleaching properties of atomic oxygen. Atomic oxygen is a powerful oxidant; due to its low atomic weight, it penetrates into tooth tissue and removes pigments from there, the presence of which determines the color of the tooth.

Bleaching is contraindicated:

  • with increased tooth sensitivity;
  • during pregnancy;
  • during lactation;
  • with untreated caries;
  • under the age of 18.

What complications can there be?

The most unpleasant moment is increased tooth sensitivity, which often occurs after the whitening procedure and persists for some time. To reduce sensitivity, the dentist prescribes special pastes and rinses. If the whitening technique is violated, there may be burns of the gum mucosa and resorption of hard dental tissues in the cervical area.

After the whitening procedure, it is recommended to limit the consumption of foods containing bright dyes, such as wine and brightly colored vegetables, otherwise we may get the opposite effect, up to the most unexpected color shades.

To summarize, I can add that regular oral care is extremely important for dental health. It is best to have your teeth professionally cleaned by your dentist once every six months. This is often enough to maintain the natural white color of teeth.

Almost everyone wants to know how to make teeth white. But whiteness is not an indicator of dental health, so let’s look at how to whiten your teeth quickly at home without harm and keep them healthy
Considering that a wide, snow-white smile is a sign of goodwill and friendliness, then the condition and color of teeth is of great importance in our lives and not only on the screen.

The color of teeth that we receive at birth is determined at the genetic level. It can be slightly beige, ivory, gray, slightly blue, and, of course, white.

Daily consumption of coffee, strong tea or treatment with certain herbal decoctions and infusions, for example, oak bark, the use of tetracycline, and especially smoking, do not have the best effect on the whiteness of our teeth. In addition, some diseases of the liver and stomach lead to discoloration of teeth.

Gradually, the enamel of teeth wears out and becomes thinner, as a result, with age, teeth lose their color even with an ideal lifestyle and excellent health.

How to make teeth white without harming enamel? First of all, you need to fulfill basic hygiene requirements: brush your teeth and rinse your mouth after eating.

The dentist can always perform a teeth whitening procedure or prescribe special products (mouth guards), gels or strips for you to use at home.

But this gives a temporary effect if the causes of plaque on the teeth are not removed.

Regular use of folk whitening products gives good results if you use them for a long enough time.

We will not consider the use of mouth guards; you can read about them on specialized dental websites.

Let's understand some home remedies.

Teeth whitening with folk remedies at home

Before you decide how to make your teeth white and start whitening them, please note that whitening is only allowed if there is no caries and so as not to harm your teeth and gums.

- Allergy or sensitivity to the components of bleaching products.

How to whiten your teeth at home without harming the enamel: 15 simple methods to make your teeth white and beneficial for their health

Perhaps there are no people who would deny that the snow-white color of teeth is one of the main criteria for assessing a beautiful smile. However, natural white color is very rare. For the majority of the population, tooth enamel has a variety of shades.

How to make teeth whiter? Today this can be done in a variety of ways. Some whitening methods are only suitable for dental clinics, while others can be used at home. One or another whitening method should be chosen based on the reasons for the darkening of the enamel, as well as the intensity of the color change.

Why does tooth enamel darken?

Dentists distinguish two types changes in enamel color: external and internal.

The external type of change in enamel color implies external influences on it. Generally, various stains can be easily removed from teeth because they are not part of their mineral composition.

The internal type of change means a change in the structure of the enamel under the influence of internal factors. It is very difficult to get rid of such darkening. Therefore, home methods of teeth whitening in such cases are ineffective.

May change due to the following factors:

How to make teeth whiter?

There are 3 main areas of tooth enamel whitening:

  1. Professional enamel treatment in dental clinics.
  2. Whitening teeth using special techniques developed by dentists for mixed use. That is, one part of the procedure is carried out in the clinic, and the other at home.
  3. Home teeth whitening using products that do not require supervision by a dentist.

Professional whitening

It includes the fastest and safest methods get white teeth. Ask any dentist: how to make teeth whiter? And he, without hesitation, will offer 3 main methods:

From a layman's point of view, all professional methods of teeth whitening have one big drawback - high cost. No wonder many people are looking for cheaper, but no less effective ways to make teeth white.

Home enamel lightening

There are many ways to whiten teeth at home. It makes no sense to describe everything, since most of them are ineffective. Let's focus only on those that really allow you to lighten the enamel by several tones.

Homemade teeth whitening using trays

These are special devices, developed by dentists for whitening enamel at home. Mouthguards are sold both ready-made and made to order. Moreover, the last option is the most preferable. The fact is that universal mouth guards can rub your gums and cause excessive drooling.

The mouthguards themselves are useless. They need to additionally purchase a brightening gel.

The whitening composition is poured into the tray, after which the latter is put on the teeth. Let’s say right away that for effective whitening, the pad will have to be kept on the teeth for several hours. Therefore, it is recommended to use this remedy at night.

The total duration of whitening is determined by the dentist. On average it does not exceed 30 days. The effect will be noticeable only after this period.

Although this method is considered completely safe, manufacturers of whitening products recommend consulting with dentists before using it.

How to keep your teeth white?

After lightening, the teeth will gradually begin to darken. This process is inevitable. However, it can be significantly extended over time. To do this you need to follow the following rules:

  • Limit consumption of drinks with chromogenic components.
  • Quit alcohol and smoking.
  • Do not take medications without first consulting your doctor.

In addition, it is possible from time to time to maintain whiteness Make enamel and use whitening products at home.

Today, the snow-white color of teeth is considered a universally recognized criterion of beauty.

However, nature bestows this color on the teeth of only a small percentage of the population. Others strive to achieve white teeth using artificial methods.

Above the question " how to make teeth white“People thought about two thousand years ago, but the history of scientifically based attempts to whiten teeth is less ancient, its origins begin in the USA, and date back to the end of the 19th century. Since that time, methods and techniques for achieving a white-toothed smile have changed. Currently, the need to identify the causes of changes in enamel color has been proven in order to select the most suitable whitening method.

Reasons for modifying enamel color

There are mainly two types of enamel color modification. The appearance of spotting on enamel can be external or internal. Extrinsic enamel stains form on the surface of the teeth and can be easily removed because they are not part of the chemical or mineral composition of the teeth.

Discoloration from the inside means that the staining of tooth enamel occurs due to disruption of the internal mineral or chemical structure of the teeth; therefore, removing such discolorations from the enamel is a much more labor-intensive process.

Factors that change the color of tooth enamel

1) Chromogenic substances.

Discoloration of tooth enamel may result from consuming foods or drinks that stain the teeth. Thus, people who regularly consume tea, coffee, cola, red wine or are exposed to tobacco smoking may notice that their teeth become yellowed over time. (In the most severe cases, teeth appear brown or orange.) This tooth-staining effect is due to the fact that some of the pigment compounds found in these foods and drinks may become trapped within the enamel layer of the tooth.

Likewise, those who regularly consume highly pigmented foods (such as blueberries, cherries, cranberries, or soy sauce) will notice this same enamel staining effect.

The degree of tooth staining in such cases correlates with the regularity of consumption of chromogenic agents, and the risk of changes in tooth enamel will be higher in cases of regular consumption of several foods/drinks from this group.

2) Medicines.

It is known that a number of medications, such as tetracycline antibiotics and fluoride, can lead to the appearance of stains in the thickness of tooth enamel. In this case, the use of such drugs during the formation of tooth enamel is important. For this reason, antibiotics such as tetracycline and doxycycline, which disrupt the mineralization of tooth enamel, are prohibited for pregnant women and children under 8 years of age.

Another exogenous therapeutic agent that disrupts mineralization processes is fluoride, the excess of which causes a condition known as fluorosis. Moreover, the change in the color of teeth during fluorosis can be quite pronounced; in total, there are 4 degrees of this condition, from single small chalky spots to large merging spots, accompanied by erosion of the enamel.

3) Age-related staining of teeth.

As a person ages, the enamel of a person's teeth usually becomes darker. This is mainly due to the processes of thinning of the enamel, when dentin, which is darker in nature, begins to “shine through” through the enamel.

4) Genetic factors.

The color of enamel, given by “nature,” can be more or less white, and the natural thickness of the enamel can also be different. In addition, a number of congenital conditions, such as congenital hypoplasia, congenital hyperbilirubinemia, affect the color of teeth.

5) Poor oral hygiene and tooth decay.

Tooth decay, or even just a lack of regular brushing habits can lead to the appearance of age spots on the teeth. At the same time, teeth without nerves take on a more grayish tint, which is partly due to fillings made of copper amalgam or other metals.

6) Occupational hazards.

Dark brown stains on enamel can be the result of prolonged contact with metals such as manganese, iron, and nickel.

7) Dental injuries.

Discoloration of tooth enamel can occur immediately after injury.

  • In general, there are only three directions on how to make your teeth white. This:
  • Professional teeth enamel whitening performed in a dental office.
  • Professional home whitening of tooth enamel, consisting of a set of procedures performed partly in a dental clinic, and partly by the patient himself.
  • Homemade teeth enamel lightening, performed at home, using products that do not require doctor supervision.

How to make teeth white at home? The answer to this question is a variety of systems for home whitening of tooth enamel - whitening toothpastes and whitening mouth rinses, various home teeth whitening systems. Among the latter, home whitening systems using plastic aligners are the most widespread. Plastic trays look like covers that cover the teeth; special bleaching solutions are placed in these covers; however, due to the loose fit of the trays, the bleaching drugs often come into contact with the gums, causing them to become chemically irritated. But you can read about it in the article.

Professional teeth enamel lightening methods are more effective, and the results of such procedures are most noticeable.

The most widely used methods are mechanical lightening of tooth enamel using ultrasound, an air-soda jet or abrasives. Another method of professional teeth whitening is chemical lightening with preparations that break down pigmented areas on the enamel.

The main contraindications to deep whitening are increased sensitivity of teeth, the presence of dental caries, exposure of tooth roots, cracked teeth, defects in dental fillings, the period of orthodontic treatment, pregnancy and breastfeeding, allergic reactions to peroxide compounds.

In recent years, professional teeth whitening technologies have used additional energies - the energy of a laser beam or ultraviolet light (laser whitening and photo whitening).

Unfortunately, teeth whitening systems have a common drawback - the effect of their use is temporary, usually the achieved whiteness of the teeth remains for a month, then the natural color of the enamel gradually returns, and the whitening procedure, perhaps to a lesser extent, has to be repeated.

If a patient has large fillings, as a rule, it is not possible to achieve a uniform whitening effect, and when selecting the color of new fillings after the teeth whitening procedure, patients are faced with a dissonance between whitening fillings and gradually darkening teeth with natural enamel.

There are often cases when tooth staining occurs from the inside, and does not respond to whitening systems. How to make teeth white in such a situation? The solution in such cases is reconstructive methods of improving the color of teeth, including the placement of composite veneers or ceramic veneers.

The dentist's task is to control the teeth whitening process to ensure aesthetic perfection without the negative impact of cosmetic procedures on the patient's overall health.

How to whiten your teeth

At different times and in different countries there were completely different ideas about beauty. For example, it’s hard to imagine, but once upon a time in Japan, beauties deliberately blackened their front teeth, there was a fashion for “rotten teeth” in Russia, merchant daughters in the seventeenth century believed that black teeth were an indicator of prosperity, because teeth, as you know, spoiled by sweets. However, much more often a snow-white smile was in fashion, and many recipes how to whiten teeth, we inherited from our ancestors.

Of course, the most effective and fastest way is considered to be dental whitening, which can take place either in the doctor’s office or at home using a specially selected composition and an individual mouthguard, which the patient must wear for some time. But if for some reason a visit to the dentist is unacceptable for you, you can try to make do with improvised means.

Baking soda

Regular baking soda is the most popular and least expensive way to whiten teeth. Usually it can be found in any kitchen, and if suddenly not, then in a grocery store. This “medicinal drug” is quite inexpensive.

The method of use is very simple: pour a little baking soda powder on top of your regular toothpaste while brushing your teeth, and perform the hygiene procedure as usual, but maybe more thoroughly. However, you should not overuse such whitening: soda wears away the enamel, and if you use it more than 1-2 times a week, then caries will quickly begin to develop on your white teeth.

Hydrogen peroxide

This drug is one of the most effective, and at the same time one of the most dangerous ways to whiten teeth at home. Usually they simply moisten a piece of cotton wool and wipe the enamel surface with it. Great care should be taken not to damage the gums. You should resort to such an extreme method as rarely as possible, since the enamel from such a procedure wears off very quickly.

Activated carbon

This method has been known since ancient times. Crushed charcoal was used for daily brushing of teeth in those days when tooth powder was not available, and this unique paste not only cleaned teeth, but also whitened them. You can crush a couple of charcoal tablets and, just like baking soda, pour them on top of the toothpaste on your toothbrush, or you can simply brush your teeth with the charcoal itself. However, rinsing afterwards requires very thorough, pieces of coal stick to the enamel and at first it seems that you have achieved the completely opposite effect.

Strawberries

This berry is not only very tasty, but also very healthy. Strawberries are recommended for vitamin deficiency, and they are also a popular folk remedy for whitening teeth. You just need to crush a few berries into a paste and apply to your teeth, leave for five to ten minutes, then rinse with water. The course of “treatment” should be at least a month, which is exactly how long the strawberry season lasts.
