Teeth Whitening: Will It Help my yellowish teeth??
Tooth whitening lightens teeth and helps to remove stains and discoloration. Whitening is among the most popular cosmetic dental procedures because it can greatly improve how your teeth look. Most dentists perform tooth whitening.
Whitening is not a one-time procedure. It will need to be repeated from time to time if you want to maintain the brighter color.
The outer layer of a tooth is called the enamel. The color of natural ... teeth is created by the reflection and scattering of light off the enamel, combined with the color of the dentin under it.
Every day, a thin coating (pellicle) forms on the enamel and picks up stains. Tooth enamel also contains pores that can hold stains.
It is also possible to have stains inside the tooth. These are called intrinsic stains. For example, intrinsic stains can be caused by exposure to too much fluoride as a child while teeth are developing. Other causes include tetracycline antibiotics. They can stain a child's teeth if taken by a mother during the second half of pregnancy or by a child who is 8 years old or younger. Teeth are still developing during these years. Trauma may also darken a tooth. Ucenter Dress yellow colored items for bridesmaid usage
