What Is Teeth Whitening? How Is It Done?
The tooth whitening process is done with a specially prepared gel being being applied to the teeth, and in most techniques the reaction is accelerated with a light source. The mechanism of the bleaching process is in the form of an oxidation-reduction reaction. The used substances expose oxygen. The substances that cause coloring in the teeth are replaced by colorless substances and whitening takes place. Teeth discoloration is based on very different causes:
Insufficient brushing, diet-linked chromogens, bacterial plaque on tooth surface, tooth exposure to trauma, coloring foods such as tea-coffee-red wine.
2. Professional Factors:
Exposure to metallic salts.
3. Genetic Factors:
A dark dental color due to genetic factors, antibiotics used in childhood, dental texture diseases such as amelogenesis imperfecta-dentinogenesis imperfecta-fluorosis.
4. Previous Dental Treatments:
Root canal treatments and color changes due to amalgam fillings.
Before the whitening process, there should be no decay, gum removal, gingivitis or abrasion in the teeth to be whitened. In such cases, all necessary treatments are done first and then whitening process is started. The reason of coloring should be determined before the whitening process. The type of whitening to be applied will be chosen accordingly.
Internal Tooth Bleaching
It is applied to teeth which have lost their vitality. If the teeth are exposed to trauma before or after the root canal treatment, bleaching is done by putting gel into the teeth. 35% perhidrol is placed in the tooth that had a root canal treatment and the process is repeated by changing the perhidrol in within certain periods, until sufficient whiteness is obtained. External tooth bleaching is applied by the physician activating the whitening pat on the tooth with a light source.
The applied gel superoxide is a caustic substance. Therefore, reversible stains may occur in the surrounding soft tissues. For this reason, the lips are isolated before the treatment and the gums are covered with a special barrier that hardens with light. During whitening with normal light equipment, the sessions take about 30-45 minutes and the result can be observed immediately. The duration of the treatment depends on the degree of whiteness that won’t cause any harm to the tooth and the degree of whiteness desired by the patient. Approximately 3 sessions are made, one every second day.
If the light device is a laser, the results are obtained in about 1 hour after one session in total.
The whitening process does not have any effect on fillings and veneers. For this reason, it is necessary to renew it according to the obtained tooth color. Teeth whitening is a process that returns depending on the time and the habits of the patient. For this reason, it needs to be renewed at regular periods. This procedure, which is simple to implement by the patient and the physician, has no complications in the long run. For this reason, it is up to all of us to exhibit a gorgeous smile that can be obtained with such an easy operation instead of hiding our laughter.
