The application made for the removal of discolorations occurred due to various reasons or because of the abnormally darker structure of the enamel and dentin, is called BLEACHING

 

Due to their exposure to external factors for years, the darkening of the teeth occurs. To remove these tooth discolorations, satisfactory bleaching of the teeth color can be achieved by the tooth bleaching processes to be applied at home or at the dental clinic.

 

The tooth bleaching process can be achieved in a harmless way up to 9-10 tones (3m scale). The materials used during tooth bleaching are for professional use and are prepared with tailor-made drugs after the dentist examination. Agents sold in cosmetics that are not made under dentist control are very ineffective and can damage dental structures.

 

Food residues build-up on teeth, tooth staining due to the tea – coffee – cigarette use and habit of tooth brushing, are cleaned by the tartar and plaque cleaning in the clinic, and subsequent polishing process. After these procedures, the teeth became ready for tooth bleaching.

 

Tooth discolorations that occur due to drugs and the structure of the teeth cannot be removed with this cleaning process. The tooth bleaching process will provide satisfactory results.

 

Tooth Bleaching can be performed in two ways.

 

  1. Home Bleaching: This is a method of tooth bleaching that you will apply yourself at home with the guidance and instructions of your dentist. A tooth bleaching plaque is prepared according to the tooth size taken from the patient’s mouth. During the night, a water-based tooth bleaching drug is put in this plaque and tooth bleaching is done with plaque and drug remaining in the mouth during the night. This process is applied for 7-10 days, according to the amount of tooth bleaching and the desired result.

 

  1. Office Bleaching: This tooth bleaching method is a process applied by the dentist where quick bleaching is desired. The gingiva is isolated and the drug is applied to the teeth and the blue light used in the radiation fillings is applied to increase the effectiveness of the tooth bleaching drug. When the desired tooth whiteness is achieved after repeated tooth bleaching sessions, the tooth bleaching process is ended. However, recent researches suggest that home bleaching should be continued as supportive method followingfor the office bleaching.

 

What should be considered in the tooth bleaching process:

 

Bleaching is a dental practice that must be performed strictly in the control of the dentist.

 

Fluoride applications should be performed for tooth sensitivities that may occur during tooth bleaching process. In this dental practice, the dentist’s recommendations must be strictly followed, too.

 

Tooth decays, tooth cracks, and broken teeth can cause tooth bleaching gel to create sensitivity along these areas. Such dental problems must be solved before the tooth bleaching process.

 

During the tooth bleaching process, tooth-coloring substances such as tea – coffee – cigarette should be avoided, regular tooth brushing and oral and dental health care procedures should be applied attentively.

 

Tooth bleaching should not be performed in patients whose tooth roots are exposed due to gingival recession.

 

BLEACHING

 

Shape and tooth discoloration in teeth are aesthetic problems that can cause troubles up to psychological disorders in many patients. People may want to have whiter teeth that are identifications ofhealth due to their social life or professional status.

 

With the development of aesthetic restoration materials in dentistry, all kinds of color, shape and position disorders in the teeth can be solved easily. Moreover, tooth bleaching is often preferred in colored teeth because it is more protective.

 

The availability of home type dental care products, which are now being sold even in markets, creates the danger of the use of substances without the dentist’s control, proper diagnosis of discoloration, and radiographic examination of the teeth. Problems such as missing faulty restorations, tooth decay, weak tooth enamel and sensitivity due to tooth cracks, tooth abrasions, gingival damage, tooth damage occurred in soft tissues can arise as a result of dental bleaching applications without dentist’s control.

 

REASONS OF DISCOLORATION IN TEETH

 

Teeth may be discolored because of internal and external reasons. External discoloration takes place on the tooth surface due to various foods, discoloration factors such as tea, coffee, cigarettes, wine, and other factors such as bacteria plaque in the tooth. Internal discoloration may occur due to the defections in teeth metabolism at the formation phase or root canal treatments, amalgam tooth restorations, metals, tetracycline group antibiotics, and substances that stick to the hard tissues of the teeth due to necrosis in the pulp tissue.

 

BLEACHING PROCESS

 

Teeth are whitened by external or internal methods. Alive teeth are whitened by external tooth bleaching and teeth that have lost their vitality with root canal treatment are whitened by internal tooth bleaching. External tooth bleaching applied to alive teeth is applied in the form of home tooth bleaching, office tooth bleaching or a combination of both.

 

As a result of dental treatments up to 8-10 tones of tooth bleaching can be achieved. Tooth bleaching can be applied to all people fromchildren to elders. Tooth bleaching can be applied from a single tooth to the whole tooth series. After the tooth bleaching process, the teeth do not return to their original situation before the tooth bleaching process in time. However, depending on the patient’s nutritional, smoking or oral hygiene habits, reinforcing dental treatments may be required in the future.

 

Home Bleaching:

 

Plastic molds are prepared with the measurements taken from the teeth, which provide a perfect fit for the patient. The dentist chooses the appropriate bleaching gel for the patient and arranges the dose. For the determined period of time (2-8 hours a day), dental bleaching gel is put in the molds and attached to the teeth. Generally, bleaching is applied at night since it is more practical. The bleaching application continues for 7-15 days depending on the factors such as the age of the patient, the degree of discoloration, and the desired tooth color tone. Hot-cold tooth sensitivities that may develop during dental treatment are removed by fluoride applications to the teeth. No smoking is allowed during dental treatment (while the plaque is attached to the mouth).

 

Office Bleaching:

It is a method applied by the dentist in the clinic, which is faster and more effective. The gingiva is isolated with preservatives and a high concentration of tooth bleaching chemical agents is applied to the teeth. The tooth bleaching agent is activated by light devices to perform the tooth bleaching process. The session takes 45 minutes to 1 hour. It is a safe method. It does not harm the enamel. Individuals with abrasion or cracks in their teeth may feel sensitivities in the teeth. These dental complaints are removed by fluoride application.

 

Internal Bleaching:

It is the method of bleaching applied by the dentist in the clinic just like the office bleaching type for the teeth that have been treated with root canal treatment. It is made by means of bleaching agents activated by chemical or light devices applied to the inner surface of the teeth.
