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. 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 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. 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.
Every day, our teeth create a thin coating or follicle forming on the enamel that picks up stains and it also contains pores that hold stains. If you talk to a dentist, you’ll be advised that the most common reasons why the teeth get yellowed, stained or discolored include poor dental hygiene, smoking or 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. Excessive fluoride exposure, taking tetracycline antibiotics, and trauma can cause intrinsic stains or stains inside the teeth. Tooth whitening procedure is very effective on extrinsic stains or teeth surface stains. Tooth cavity must be treated prior to tooth whitening because 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 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. A dentist may also use different teeth whitening procedure to whiten the tooth inside, by placing a whitening agent inside the tooth and putting a temporary filling over it, left for several days and removed.
