Teeth can become discolored in time depending upon various reasons. There are two main types of tooth discolorations:
Extrinsic stains caused by cigarettes, tea and coffee can be bleached through dental scale.
These are stains that are found in the inner structure of the teeth. They may occur depending upon the drug use or too much exposure to fluoride. Bleaching aims at removing stains in tooth enamel through bleaching gels.
There two types of bleaching:
A transparent mouthpiece, which is customized to exactly fit the patient’s teeth, is prepared. This mouthpiece, into which carbamide peroxide is applied, is used for 4-8 hours a day. Bleaching is achieved approximately in 5 days. Home bleaching is cheaper than office bleaching.
Office bleaching is an effective and professional bleaching method. There is a light source which activates the bleaching gel. Teeth can be whitened in 6-8 tones of color in such a short period of time as 1 hour. Advantages of office bleaching are that it can be completed in a short time. Moreover, peripheral tissues are preserved and the color acquired through the dentist’s direct application can be maintained.
