Your smile may be the first thing that someone notices about you, and if you want brighter and whiter teeth, there are some things that you may want to know about teeth whitening. Teeth whitening is a cosmetic dental procedure sometimes referred to as dental bleaching, yet there is a difference in definition.
Teeth whitening restores the teeth to their natural color, and bleaching whitens teeth beyond the natural color. There are many reasons that teeth may become discolored, and there are professional procedures as well as home procedures that may help to whiten your teeth.
Tooth discoloration: Causes
Adult teeth are usually whiter than deciduous or primary teeth. As the enamel becomes more porous, teeth become darker. The staining of teeth can be caused by bacteria, certain dark-colored foods, and beverages as well as tobacco and acidic foods.
Different Types of Teeth Whitening
Cosmetic dentists are experts in teeth whitening. They may use gels, laser light, or a combination. The first visit to the dentist will involve a thorough examination and cleaning of the teeth. A cheek retractor is inserted, a hardening resin is painted on the gums to protect them from the bleach, and bleaching gel is applied for 15 to 30 minutes. This gel is suctioned or rinsed off, and fresh gel is again applied for 15-30 more minutes.
