Teeth Whitening

What is Teeth Whitening?

The first noticeable part of the tooth structure is the tooth enamel. The dentin layer under the enamel is responsible for the color changes that occur on the enamel surface, which can be aesthetically disturbing . Tooth enamel, whose natural color is white, reflects the color of the dentin layer under it with its translucent feature. Over time, the teeth turn yellow or brown under the influence of tobacco products and coloring foods. Such coloring products are made from pulp. They reach the dentin layer, causing further yellowing of the naturally yellow dentin . The color change observed on the enamel surface is actually a reflection of the dentin.

For What Reasons can Teeth Turn Yellow?

  • Trauma to tooth enamel
  • Some drugs used
  • Coloring watery foods such as tea, coffee, red wine, etc.
  • Drinks and foods with high acid and sugar content
  • inadequate dental care
  • Structural factors

be corrected with oral and dental health practices such as tooth brushing, flossing, mouthwash, etc. Oral health care routines reduce the effectiveness of the factors that will trigger staining on the teeth. For existing yellowing, teeth whitening, which is called office type, can only be performed by dentists in a clinical setting. No matter how orthodontically correct the shape of the teeth , unless they are of the required whiteness, they are unlikely to look aesthetically pleasing. There are some criteria to be considered in order to perform the teeth whitening procedure applied with chemical agents. The prerequisite is to have healthy teeth and gums. It should be noted that teeth whitening can only be performed on natural teeth. If there are materials such as veneer, bonding ( composite filling), porcelain lamina on the tooth, the teeth whitening procedure is not applied. In addition, problems such as fractures, cracks, and habit of clenching are important in terms of how effective the whitening procedure will be and are taken into account before the application.

How Is Teeth Whitening Performed?

Teeth whitening can be applied in 3 sessions until the determined tooth tone is achieved. Each session must be waited for 15 minutes after the application. The smile line is taken as a basis when determining the area where the whitening process will be applied . The steps to be followed in the procedure can be listed as follows:

1. Color Tone Planning: Although the hue is determined by the patient’s preferences, overdoing it can result in an artificial appearance. Skin and lip color are clues to the ideal tone. The aesthetic dentist will make the necessary guidance regarding the tones that may be suitable.

2. Wearing Protective Apparatus: During the procedure, the gums, tongue, lips and eyes should be isolated and goggles should be worn. Isolating apparatuses are worn to protect the mouth area against chemical agents to be used during application, and to protect the eyes against the light source.

3. Teeth Stone and Tartar Cleaning: Before starting the teeth whitening application, the teeth should be made ready and suitable for application by cleaning the tartar and tartar.

4. Application of the gingival barrier: A protective gel is applied between the gingiva and the teeth in order to protect the gingiva from the chemical-containing whitening agent. All openings in the upper and lower teeth are sealed with gel and hardened by a light source.

5. Application of Teeth Whitening Agent: There is a hydrogen peroxide component in the tooth whitening gel, which has a whitening effect. The whitening agent is applied to the lower and upper tooth surfaces in layers, and light is applied. After waiting for 15 minutes, the applied whitening gels are removed from the teeth with the help of an aspirator. After the teeth are washed, color control is done. If the desired tone is not achieved, the washed teeth are completely dried and the whitening gel is applied again. The process can be repeated up to 3 times.

6. Meeting the Patient with the Mirror: After the targeted color tone is achieved and the chemical agent residues are not left on the tooth surface, all protective apparatus in the mouth area is removed. The result of the application can be observed immediately. The satisfaction of the patient is the biggest success criterion of the application. Satisfaction is hidden in the second smile reflected in the mirror.
