Tooth whitening lightens teeth and helps to remove stains and discoloration.
Whitening is not a one-time produre, it will need to be repeated from time to time if you want to maintain the brighter color.
What it’s used for:
The outer layer of a tooth is called the enamel. the color of natural teeth is created by the reflection and scattering of light of the enamel, thinner enamel allows more of the color of the dentin to Show throught having smoother or rougher enamel also effects the reflection of light and therefore the color .
Every day, a thin coating “pellicle” forms on the enamel and pickes up stains. Tooth enamel also contains pores that can hold stains.
The most common reasons for teeth to get yellow or stained are:
· Using tabaccco
· Drinking dark-colored liquids such as coffee, cola, tea and red wine.
· Not taking care of teeth
Aging makes teeth less bright as the enamel gets thinner and the dental becomes darker.
