These factors include habits and practices, diet, trauma, medications and tooth orientation can all contribute to the color of teeth. The methods in which teeth whitening fall under cosmetic dentistry. Dentists describe the tooth whitening process to eliminate discoloration and stains on the teeth, and it can also brighten the natural pigmentation of the teeth. The most popular teeth whitening techniques available today are laser teeth whitening done by specialist dentists at office setting and at-home teeth whitening with custom-fit trays. However, it is recommended that even at-home methods are performed under your dentist’s supervision in order to to ensure the safest results.
