Teeth bleaching – types of teeth bleaching

With the advent of new methods in dentistry, having a more beautiful smile is now within the reach of more people. One of the most popular teeth whitening methods is tooth bleaching. The color of tooth enamel changes due to consumption of substances such as coffee and tobacco. Although many stains can be removed with teeth whitening techniques, whitening may be uncomfortable for people with sensitive teeth. Teeth bleaching is one of the methods of whitening teeth and correcting smile design, with the help of special materials. This work can be done both in the dentist‘s office and at home by the person himself. Of course, in each of these two methods, different materials are used for teeth bleaching. Teeth bleaching increases people’s self-confidence and gives a person a sense of beauty. Therefore, this method has many fans. Teeth bleaching is one of the first options to have a beautiful smile design in people.

The tooth has two parts: dentin and enamel

Enamel is on the dentin. This part creates the white appearance of the teeth. With age, the thickness of tooth enamel decreases and gradually the color of ivory becomes visible and the tooth looks yellow.

Factors that cause teeth to turn yellow include:

  • Smoking
  • Improper diet
  • Failure to observe oral hygiene
  • Consuming sugary drinks

Of course, sometimes it has been seen that people who regularly brush their teeth and use dental floss, their teeth turn yellow due to the consumption of sugary foods and so on.

Bleaching method causes less damage to tooth enamel than other methods such as dental composite and dental laminate. Composite is a restorative tooth whitening material that is used to fill teeth that are empty and denervated. Dental laminate is also a structure that is molded by the dentist and made in the laboratory and mounted on the tooth.

Types of teeth bleaching methods

Teeth bleaching can be done with two methods:

1) Office Bleaching or bleaching in the dental clinic

This method of bleaching is performed in the dentist’s office by a bleaching specialist and special chemicals with high concentration and short duration are used. The dentist stains your teeth with an acid solution, or so-called etching, and then applies an oxidizing agent to your tooth enamel. Then the teeth are exposed to intense light or laser (this method is also known as laser tooth bleaching). Complete bleaching in this method usually takes three to four sessions and each session takes about 30 to 60 minutes. The dentist you visit must have enough skills in this field so that chemicals do not cause sensitivity and discomfort such as gum pain and toothache. To prevent oxidizing substances from coming into contact with the gums, the dentist uses protective gels that keep it fixed on the teeth with a blue light during the bleaching period. The cost of teeth bleaching in a dental clinic is usually more expensive than at home. Of course, it also depends on the materials used for bleaching.

Immediate teeth bleaching

A new method recently used for immediate teeth bleaching is called power bleaching, in which concentrated hydrogen peroxide is used. Using this method can completely whiten your teeth in just one session. But note that your teeth will be temporarily whitened and after one to three years they will be dark again and you may need to repeat this procedure again.

2) Home Bleaching or teeth bleaching at home

This bleaching method is performed under the supervision of a dentist at home and by the person himself. The type of material used in this method is different from the material used in the dentist’s office. In this method, the dentist prepares a mold of a person’s teeth, and in the laboratory, a plastic tray (night guard) is made from that mold. Bleaching gel is poured into the nightguard mold and placed on the tooth. The time that the mold should be placed on the teeth is between one and six hours a day, depending on the condition of the individual’s teeth. The whole process is a treatment period between one and two weeks for each jaw. Because the mold should only be placed on one of the jaws at a time. This method requires patience. If a person does not have enough time and wants to do teeth bleaching quickly and in the shortest time, it is better to do it in a dental office. The cost of this method is cheaper than teeth bleaching in a dental clinic.

It should be noted that before using any of the bleaching methods, teeth that are rotten and have problems should be repaired and scaled.

Cost of teeth bleaching

The cost of teeth bleaching varies according to the type of bleaching you do (at-home bleaching and dental clinic bleaching). Tooth bleaching is one of the best methods of whitening teeth and is a better method than dental laminate and dental composite; Because it has fewer complications and a lower price.

What materials are used in bleaching?

The two main chemicals used in bleaching are hydrogen peroxide and carbamide peroxide. Hydrogen peroxide is used in dental offices and by doctors. But carbamide peroxide is used at home by the person himself. It should be kept in mind that both methods should be done with the approval of a cosmetic dentist and the person should never do this without having the necessary knowledge.

How to whiten teeth by bleaching chemicals

By penetrating the crystalline structure of the teeth, the mentioned chemicals oxidize the pigments that have been deposited on the teeth over time. As a result, the color of the tooth’s dentin becomes brighter. An important point is that due to the chemical nature of these substances, there should never be any contact between these chemicals with the gums and the face.

Today, we see many powders that whiten teeth in the market. But it should be kept in mind that these substances cause bad side effects and cause serious damage to the mouth and teeth. For example, it may cause wear and loss of tooth enamel layers. Therefore, products must be used in this field that have been approved by cosmetic dentists.
