Is teeth whitening dangerous?

Smiling in bleached white teeth seems a good idea and many want whiter teeth, but is it safe?

What methods are used for teeth whitening?

Bleaching is a chemical process using peroxide derivatives, mainly hydrogen peroxide and urea peroxide. When they come into contact with water, they break down into intoxicating oxygen radicals. These oxygen radicals digest the absorbed color pigments into smaller and colorless particles. The penetration of the active ingredient into the dental tissue is enhanced, for example, by laser, ultraviolet and plasma lamps.

How safe teeth whitening agents are?

Peroxide derivatives have been used in dental care for twenty years. If their use is not safe, healthcare professionals should not use them at their reception. The substances used by professionals are CE-labeled, investigated substances.

In teeth bleaching, the substance does not come into contact with mouth mucous membranes, lips and gums as they are protected by a rubbery substance.

If you have allergies, is it safe to bleach your teeth?

For peroxide allergies we have never come across, but allergic and hypersensitive can react, for example, to odors of bleach chemicals. When an allergic person comes to the clinic to discuss possible bleaching, one should include a list of the substances that cause symptoms. For asthmatic it is good to take medication with them to the teeth whitening session.

Is there age limit for teeth whitening?

The teeth turn yellow with age. The most common tooth dyes are red wine, tea, coffee and tobacco. The tooth surface or mica wears over the years and reveals the inner, yellowish part of the tooth and deeper stains.

Bleaching is only done for a person of the age of 18 at least, no upper age limit. A very old person's mica may have become so thin that bleaching will not work well and is not worth doing. Also, for a woman who is pregnant or who is nursing does not get her teeth whitened.

Do I have to have a tooth inspection before bleaching?

The teeth and mouth condition should be checked, the holes repaired, the tartar removed and gums in good condition, before the teeth can be whitened. Large mica damage can prevent bleaching.

The first time is a planning visit, listening to the customer's wishes, deciding on the bleaching method and the color of the teeth - the goal is to get to the most natural outcome.

At the same time, it is possible to check whether bleaching is the best way to whiten the tooth. For a  tough gray tooth, bleaching doesn’t work too well. Sometimes dental veneers aka porcelain veneers are the only option.

Can dental whitening be done by yourself (DIY)?

Teeth can also be bleached at home. A mold of the teeth is required for bleaching. The molds are used for several days in a row, 30-60 minutes per day. Substances intended for home-use are not as strong as the ones used at the clinics.

How do the whitening products ordered from the internet differ from those used by professionals?

Web products may also used by professionals, but professionals know the right products and how to use them. Substances intended for professional use may be too strong for mucous membranes.

In a magazine there can be an article about teeth whitening with baking soda or salt. They may not be worth trying. Their effect is based on rubbing, not chemistry, and are therefore harmful to the teeth. Rubbing can remove surface staining, but the tooth color change can not be achieved by abrasion.

Whitening toothpastes hardly ever truly whiten teeth.

Whitening toothpastes hardly whiten teeth. Most of them are based on abrasion and the removal of surface discoloration. Some are based on a chemical process, but their power is not enough to bleach the teeth.

What kind of disadvantages can bleaching have?

After bleaching, the teeth may hurt because the bleach may temporarily irritate the tooth nerve. Usually the aching lasts for a few hours or not more than a couple of days.

Aching can be prevented by using toothpaste intended for sensitive teeth prior whitening for couple of weeks.

Dentists have a special subtance at the reception, which closes the pores opened with chemicals in bleaching. The name of the substance is Tooth Mousse, which contains calcium phosphates and calcium fluoride. The customer can put it in bleach molds and use it at home for a while.

How permanent is the whitening result?

Same agents will stain the teeth before and after bleaching. It is not advisable to drink coffee immediately after the operation. The withdrawal period for different foods to be avoided in different methods is different and varies from a few days to a few weeks. To maintain the achieved result, there is a proprietary gel that does not consume the teeth.

The goal is to have a good bleaching result for several years. It gets expensive and the teeth can not withstand if bleaching is needed a few times a year. For example, in a laser treatment, a tooth is applied to huge amount of energy that the tooth may get irritated and start to hurt.

But nothing is eternal. Mica gets worn out and the yellowish dentine starts to shine through the mica.

How much does teeth whitening cost?

The professional whitening varies between 250-1000 dollars. The customer receives a price estimate with the first visit.
