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. Tooth whitening is not just a one-time procedure, it involves series of sessions to maintain the brighter teeth 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 another important factor why the enamel gets thinner and the dentin becomes darker leading to less bright teeth. Excessive fluoride exposure, taking tetracycline antibiotics, and trauma can cause intrinsic stains or stains inside the teeth. 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. Teeth whitening products cannot make the teeth whiter is the gums are receded with exposed yellow or discolored roots of the teeth. 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 be cleaning your teeth to remove bacteria, food particles, and other substances that build up your teeth, contributing to staining, and after this, the whitening procedure starts. 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. There are gel commercially prepared whitening gel to whiten teeth, or whitening agents activated laser light or heat. If vital whitening or surface teeth whitening will not improve the appearance of your tooth because of a previous root canal treatment or intrinsic stain, your dentist will be using different teeth whitening procedure such as placing a whitening agent inside the tooth and putting a temporary filling over it, left for several days and removed.
