Teeth Whitening

Teeth whitening is completely safe and we guarantee a lasting effect as long as it is done in a controlled environment, in the dental office, or in ambulatory with a medical prescription. Tooth whitening is always an effective treatment. Sometimes it may not fit the patient’s expectations. The result depends on factors such as the type of tooth, the diet, the age of the Patient and his oral hygiene habits. However, it always allows to obtain whiter teeth than the initial state.

Dental whitening is an essentially an aesthetic treatment. It consists of the application of a gel for teeth whitening on the dentition. This gel will lower the tone of the teeth, making them clearer.

Depending on the type of tooth, the patient’s diet, their age and their oral hygiene habits, in a patient considered “ideal”, especially if they are young, a whitening can last 5 or 6 years. Over this time, the teeth gradually darken, with aging. However, they should not be in a tone as dark as the tone prior to treatment. After that time, there is always the opportunity to make a reinforcement and re-whitening the teeth.

The best treatment option always depends on each case, the type of bleaching the patient wants and the level at which we want to reach in terms of the whiteness of the teeth.


Before whitening your teeth, you should be examined by a dentist or dental hygienist who will assess whether it is possible to whiten existing discolourations and decide which method is most suitable. If there are holes, they must be repaired and the whole tartar should be removed. It is also important that you have good oral hygiene.

Before having their teeth whitened, they should be examined by a dentist or dental hygienist who will assess whether it is possible to whiten existing discolourations and decide which method is most suitable. The fillings and crowns you have cannot be bleached and are not affected by bleach.

You can lighten your own discolored teeth for a better overall impression if you want to put a crown or bridge in your mouth. If you have an old crown lighter than your own teeth, the teeth around the crown can be leached so that the color difference is reduced.

This is how the treatment works

In whitening discolored teeth, different types of whitening gels are used. The bleach substances used penetrate into the enamel and tooth bone. The dark particles that discolor the teeth are broken.

If you think you have discolored teeth, it is important to consult a dentist if your teeth can be whitening and, if so, how to do so.

Depending on the method the dentist uses, it can take from a few hours in the treatment chair to a few days or weeks of treatment at home. In the case of more severe discolorations, it may take even longer.

Bleaching is a chemical process. Bleach penetrates enamel and tooth bone. In this place, discolored dark substances are decomposed into smaller, non-colored substances.

Before starting treatment, the color of the teeth should be documented. This can be done by the dentist, for example, by taking a picture of all the teeth that will be bleached. In this way, you can more easily assess how was the treatment later.

Most common gel

In teeth whitening, the most commonly used gels are those that, among other things, contain the substances urea peroxide or hydrogen peroxide. The bleach gels used on the bleach rails also contain potassium nitrate and fluoride, which should lessen the problem of irritation during treatment.

Different types of bleach

Dental bleaching agents are cosmetic products. They cannot be used by persons under 18 years of age.

Here are some different types of preparations used for teeth whitening:

Bleaching agents for dental care that can contain a maximum of six percent hydrogen peroxide or the equivalent potency of another agent.

Bleaching gels that cannot contain more than six percent hydrogen peroxide or the equivalent potency of another agent. You can use the gel yourself after being examined.

Disposable strips and disposable rails covered with hydrogen peroxide gel. They are used in home treatment.

Varnish that contains hydrogen peroxide or urea peroxide and that is brushed on the teeth during treatment at home.

Bleach sold in department stores or over the Internet. They may contain substances such as sodium perborate or sodium chlorite. It is often unclear in what amount. It can also contain acidic solutions such as citric acid. Always talk to your dentist or dental hygienist before using products purchased online.

Agents that contain more than 0.1 percent hydrogen peroxide can only be sold to dentists. This also applies to the corresponding power force of another

First treatment at the dentist

For the first time in each treatment cycle, you will need the help of a dentist to use the whitening. You can also get treatment from a dental hygienist under the supervision of a dentist. After that, you can take bleach home to finish the treatment yourself.

If you receive treatment in a dental clinic, the teeth are prepared in different ways, depending on the whitening to be used. A rubber cloth is often used to isolate the teeth, so that the gums and mouth are protected against strong gels.

The treatments that are done in the dental clinic take about an hour, but it is usually necessary to go back once or twice more to repeat the treatment. It depends on how satisfied you and your dentist are with the results after the first time.

The plastic rail is filled with gel

First, an impression of the teeth is made in the dental clinic if you are going to whitesize your teeth at home. With the help of molding, a model is made in which a plastic splint is made that fits your teeth. You fill the plastic splint with bleach gel and use one to two hours a day, or at night if it is too difficult to have during the day.

Frequently, three to four days of treatment may be sufficient. It may be necessary to treat your teeth for up to two weeks if you have severe discoloration.

It is not possible to say that one method is better than the other. Treatment in the clinic is faster, but the result is no better than the treatment you do at home. So far, there is little research on the efficacy of clinical bleaching and the duration of the outcome.

Whitening of filling teeth

When the teeth are to be bleached, the technology is different. The most reliable and risk-free method is a gel containing hydrogen peroxide. Treatment is repeated at intervals of three to five days until the result is good. Usually does the treatment two to three times.

The post is usually replaced after three to seven days. The insert may need to be replaced one or more times before the result is good. Sometimes the result may be better if this treatment is combined with teeth whitening in the usual way.

When you have a tooth with root, the result is almost always good. Often, the tooth darkens again over time, but then treatment can be repeated.

The root can be severely damaged when you whiten filling teeth, although this is rare. Usually you have no symptoms and in some cases the changes are only discovered long after the tooth has bleached, and only when the dentist takes an X-ray.

Possible Problems

When you whiten your teeth, your gums can become swollen, a little sore or irritated. It is important that you pause the treatment for one to two days or until the gums have healed.

It is the contact of the bleaching gel with the gums that can be irritating, especially when using stronger preparations or when the plastic splints do not fit well.

Problems with toothache

You may also experience discomfort in the form of rashes when whitening your teeth, but they disappear. Irritation occurs due to penetration of the bleach into the tooth and the creation of an inflammation in the pulp. Symptoms usually disappear within one to two days if you discontinue treatment.

Do not eat or drink anything with strong colors during treatment and a few days later. It can be, for example, red wine and blueberry.

After teeth whitening, these are usually treated with fluoride because tooth enamel needs to be strengthened.

Will it look good after a treatment?

How good the result of bleaching is depends, among other things, on the following:

• What kind of discoloration do you have.

• Discolorations have been present for how long.

• What is the original color of the tooth.

If you have fillings that need to be replaced after bleaching, you should wait one to two weeks after the end of treatment. It is important that the color of the teeth stabilizes, but also that there is no bleach residue. These residues prevent the plastic filling materials used from solidifying properly.

Lightening treatment usually lasts from one to three years. You can combine with your dentist to repeat treatment when necessary.

Studies have not yet been done to show how teeth are affected by repeated whitening. But so far there is no indication that there are health risks, only treatment is done properly, without very strong funds.

When is treatment inappropriate?

If you have problems with burns in the form of neck of teeth, surfaces of unprotected roots, damage to the brush or fine enamel, you should not whiten your teeth. With these problems, the risk of side effects in the form of irritability increases.

Do not whiten your teeth if you smoke or smoke snuff. Tobacco dyes can worsen the outcome of treatment. Bleach can aggravate the damage that tobacco can cause to the oral cavity.

Do not whiten your teeth if you are pregnant or nursing. There are no studies showing whether the bleach affects the fetus or the baby.

It is risky to whitening the teeth without having contact with the dentist. You cannot judge for yourself which solution is appropriate for use. Only trained dental staff can do that.

Most discolorations can be bleached

Teeth with yellow or brown discoloration are usually easier to lighten than others.

Metal discolorations are almost impossible to bleach, such as amalgam fillings. The same applies to teeth that have suffered blow or injury and where the pulp has been damaged. These teeth are usually darker or more yellow than the other teeth.

Various causes of discolored teeth

The fact that we have different colors in the teeth is totally natural and many are darker in color over the years. The color of the teeth can also be changed by strong dyes of tobacco, food and beverages that penetrate the enamel and tooth bone.

Over time, the filling teeth can acquire a bluish-gray discoloration.

Discolorations can also occur before permanent teeth appear in the mouth. The most common causes are chronic diseases with high fever in young children, or situations in which the baby’s teeth are exposed to blows or damage that affect the growth of the enamel of new teeth.

It may also be due to hereditary diseases that affect the teeth when they form in the jaws, or when the child has taken a certain type of antibiotic, tetracyclines.

May cause discoloration if children up to six years of age drink water that contains too much fluoride. The most common is to appear as white spots on the teeth.

This is especially true if the child drinks water from a well whose water has not been analyzed.
