Teeth whitening

Teeth lose their whiteness over time due to consumption of food, drinks (coffee, wine, and tea), and cigarettes. Teeth whitening can be done to correct this situation. Compared to porcelain veneers, tooth whitening is an easy, reliable, economical, and more protective process because the teeth are not abraded.

Staining and discoloration in teeth

It is unique to the person such as tooth color, eye color, and hair color. The ratio of the elements contained in the tooth to each other determines the color of the tooth. The enamel surface has a small perforated structure that is invisible to the eye. The natural color of the tooth may change over time by being affected by external factors.

Yellow and slightly brown discolorations that occur over time give the best results. Dark brown and blue-gray discolorations are hardly bleached discolorations in the deepest structures of the tooth. Such staining usually occurs as a result of the use of some antibiotics during the development of the tooth, and the number of teeth whitening sessions must be increased to achieve the desired result.

How is teeth whitening applied?

There are two types of treatment methods that can be chosen. The first of these is the method that provides faster results in your dentist’s office (Office bleaching), the other is the method that you will apply yourself at your home (Home bleaching).

How is home bleaching done?

The home whitening method is also done under the supervision of the dentist. At the first appointment, the dentist takes measurements from the patient’s teeth and prepares a transparent plaque that will pass on the teeth with this measurement. This plaque, which is used by the person who is whitening at home, provides the application of the whitening agent to the teeth of the patient and the protection of the gums.

How is office bleaching done?

The whitening process is done in one session, but the session can be repeated if necessary. For this purpose, the gums are isolated and a gel with whitening property is applied to the teeth. Special light sources such as laser or halogen, LED can be applied to activate the gel. Diode laser devices that activate the gel with the heat they give in whitening can be used. Even more reliably, since it provides superficial absorption, Sertdoku laser devices also provide safe bleaching in a very short time without giving any heat to the teeth.

It is possible to do the whitening process performed in the office faster without damaging the teeth. With laser devices, whitening can be achieved in about 30 minutes without creating sensitivity. This laser wavelength provides absorption of only 100 micrometers in the tissues being studied and is absorbed in water. For this reason, it is absorbed in the top layer of the whitening gel and ensures that the gel is immediately active without going into the deep layer. This ensures that the process is accelerated and at the same time, there is no heat in the tooth. Thus, post-processing sensitivity is also minimized compared to alternative methods.

The bleaching process performed in the office takes between 30 minutes and 1 hour on average. A few days after bleaching, the color of the teeth takes its final shape. The home-type bleaching process with the gels placed on the plates formed with the impression is taken in the clinic gives results within 1-2 weeks compared to the gel.

In the bleaching process performed with hard tissue lasers, pain does not occur unless the gel reaches the dentin and there are micro-cracks in the enamel. There may be little sensitivity in other methods, and this usually resolves within 24 hours. To eliminate this, your dentist can apply fluoride at the end of the bleaching process.

The effect of tooth whitening usually varies between 1-2 years. If you do not smoke heavily and do not consume too many foods that will color the teeth, this period will be longer. Also, if the whitening procedure performed in the clinic is supported by the whitening procedure performed at home every 3-6 months, the period can be extended.

Whitening agents are materials that are effective on the top layer of the tooth, the enamel, and do not damage the enamel. If for any reason, the tissue under the enamel, called dentin, has been exposed in the tooth, this area should either be covered with filling or isolated by the physician. The whitening agent should never be applied to dentin tissue. It is not always possible for the patient to notice the eroded enamel tissue and the emerging dentin tissue. If the patient uses bleaching products in the markets without consulting the physician and the dentin is exposed, he may face tooth sensitivity that does not go away. Therefore, whitening agents should be used under the control of the dentist.

If there is a darker color among the white teeth compared to the other teeth, this tooth has lost its vitality and it is a tooth with root canal treatment. The color of the tooth can be lightened by the devil bleaching process to be applied to this tooth. The whitening substance is placed into the tooth by the dentist and the whitening substance in the tooth is changed by the dentist at intervals of 1-2 days until the desired result is achieved. The result is usually excellent and takes an average of 1 week. In this type of bleaching, it usually takes a long time for the color to return to its former color.

After bleaching, it is beneficial to stay away from foods that can color the teeth such as tea, coffee, cigarettes, red wine, cherry juice. Paying attention to general oral care will also prevent the recurrence of discolorations.
