Is teeth whitening process considered to be free of the consequences?

Teeth whitening, usually hydrogen peroxide, and sometimes carbamide monoxide, both of which are completely safe. The percentages vary according to professional use or use at home, and carbamide is often used with patients who develop sensitivity after the teeth whitening process.

Is teeth whitening process considered to be free of the consequences?

The American Dental Association announced its acceptance of some teeth whitening materials and solutions, after testing them on large numbers of American auditors. Among the solutions that were accepted by the association are:

Or not:

10 percent to 22 percent carbamide peroxide is the only solution a dentist is allowed to prescribe for home whitening.
Second: 35 percent hydrogen monoxide – Hydrogen Peroxide – a solution used to whiten teeth at the doctor’s clinic. These two solutions are the only ones who have recognition. And they have no effect on the strength and hardness of the tooth. As for the rest of the teeth whitening methods, they are not recognized and can be effective, but the American Dental Association does not guarantee their safety for human use.

The differences between home whitening and dentist whitening,

The period of teeth whitening at home takes only two consecutive weeks, after which the whitening should be stopped. The degree of color improves according to the condition of the teeth and many other factors, but the whitening process at the dentist often takes one visit (less than an hour), but the sensitivity caused is usually much greater than that which is done at home.
The supervision varies, as the whitening process takes place in the dental clinic under the supervision of the doctor. As for the home whitening process, it lacks this supervision. Therefore, the patient must be alerted to the need to stop whitening for a period of one or two days in case of feeling sensitive in the teeth and if the sensitivity does not subside, the dentist should be visited quickly.
As for the long-term results of whitening, teeth whitening does not last for life, as people who consume food or drinks that contain some dyes (such as sweets, colored juices, tea and coffee), or smokers, their teeth begin to gradually yellow after one month of whitening. The bleaching effect can last for a year or more in non-smokers and those who do not consume foods and drinks containing dyes. Whitening does not remove the outer layer of the teeth when using solutions authorized by the American Dental Association, nor does bleaching damage the dental fillings. It should be noted that fillings, crowns and bridges do not get whiter with teeth whitening solutions. Therefore, teeth whitening may make the color of the filling, crown or bridge different from the color of the natural teeth affected by bleaching, and therefore the filling or crown must be changed or not bleached to avoid this problem.
