A very popular dental treatment performed under the expertise of a dentist is tooth whitening, that is used in removing stains and discoloration. Tooth whitening is a popular cosmetic dental procedure, and almost all dentist perform tooth whitening. It is not only done one-time, it involves repeatedly undergoing the treatment to maintain the brighter color of the teeth. The outer layer of the tooth is called enamel, and the tooth color is created by light reflecting and scattering through the enamels, combined with the dentin’s color. Hereditary factor 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 inside the tooth also happen because of too much fluoride exposure in childhood while the teeth were still developing. Tooth whitening is considered the most effective on extrinsic 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. If the gums have receded, the exposed roots appear yellowish and discolored which cannot be treated by teeth whitening products. Your dentist will be taking a photograph of your teeth prior to the procedure to help in monitoring the progress of the treatment.
Your dentist will clean your teeth prior to the treatment to remove food particles and bacteria. Home whitening gel can be applied daily for two to three weeks, and your dentist can make trays for holding the whitening gel that can 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.
