A very popular dental treatment performed under the expertise of a dentist is tooth whitening, that is used in removing stains and discoloration. It is considered as a cosmetic dental procedure because it greatly improves the appearance of the teeth. In order to maintain Tooth whitening involves repeated sessions to achieve the ideal whiteness or brighter color. The outer layer of our teeth is called enamel, and the teeth color is created from the color of the teeth and the light reflection and scattering off the enamel. Genetic factor greatly affects the smoothness and thickness of the enamel. An enamel that is thinner allows more color of the dentin to show, and a rougher and smoother enamel affects the light reflection and so as the color.
The teeth becomes discolored because of the follicle of thin coating created by the teeth that picks up stains and the teeth enamel also have pores holding stains. When it comes to the most common reasons why the teeth get stained or discolored according to dentists include poor dental hygiene, tobacco use, and excessive intake of dark-colored liquids such as cola, coffee, tea and red wine. Aging is also a predisposing factor why the teeth is less bright because the enamel gets thinner and the dentin becomes darker. Intrinsic stains or stains found inside the teeth also occurs when there was excessive fluoride exposure when the teeth were still developing, and also because of tetracycline antibiotics. Tooth whitening procedure is very effective on extrinsic stains or teeth surface stains. Before the dentist will be doing teeth whitening treatment, any cavities need to be treated first because the whitening solution can pass through these decayed areas, reaching the inner parts of the teeth. Teeth whitening products cannot make the teeth whiter is the gums are receded with exposed yellow or discolored roots of the teeth. Tooth whitening can be done at home or in a dental clinic, and the dentist will usually take photos of your teeth as a means of monitoring your progress.
Your dentist will clean your teeth prior to the treatment to remove food particles and bacteria. Whitening gel products can also be applied at home daily for two to three weeks, and your dentist can make trays to hold the whitening gel to fit your teeth properly. Whitening agents use activated laser light or heat. If vital whitening will not improve the appearance of your tooth because of a previous root canal treatment or intrinsic stain, the dentist can use a different teeth whitening procedure, by placing a whitening agent inside the tooth and putting a temporary filling over it, left for several days and removed.
