Teeth whitening procedure of polishing teeth while removing stains and discolorations. The teeth whitening process is one of the most popular cosmetic dental procedures because it improves the appearance of teeth. Products used in teeth whitening typically contain one of two active dental ingredients. Hydrogen peroxide or carbamide peroxide. These bleaches break down stains into smaller pieces and make the color less concentrated, resulting in brighter teeth.

Types Of Teeth Whitening


In-Clinic Teeth Whitening: In-clinic whitening is the most common type of whitening. During an in-office procedure, the dentist uses a powerful whitening gel with a special light that makes whitening happen faster. A whitening gel containing hydrogen peroxide is applied to the teeth of the aesthetic area and left for about 15-30 minutes. The bleaching gel is absorbed or washed off and the gel is applied for an additional 15 to 30 minutes or more. In-office whitening is performed on teeth with live nerves.
Home teeth Bleaching: Home bleaching is a method performed outside the clinical setting, at home or at work, using custom-made ready-to-use plates or devices. Special whitening plates are prepared according to the measurement function perceived by the lower and upper jaws. The whitening gel suitable for the patient is selected by the dentist and the dose is adjusted. During the specified time, the person wears the forms in which the whitening gel is placed on the teeth. This practice is usually best done at night as it is more useful.

Care should be taken not to apply too much whitening gel in-home teeth whitening procedures. The gel can irritate the gums. In such a situation, it is recommended to wash the gums immediately and apply a cream containing vitamin E. Home bleaching is used to treat internal staining of teeth and is most commonly used on a tooth that has had a root canal treatment.

Teeth Whitening Advantages and Disadvantages

Dentin, which is the hard, inner part of the teeth, is responsible for tooth color. As we age, our enamel thins and our dentin darkens. This causes our teeth to appear yellower. Yellow tooth discoloration typically responds well to teeth whitening products. Yellow teeth are easier to whiten than other tooth colors.
