Tooth discoloration explained by Dr. Smiley

Should you proceed with teeth whitening?

The cause of tooth yellowing is food and drink.
If you smoke it is also the effects of nicotine and tar.
Wine, chocolate, coffee, tea, blueberries and other create stains
that cannot be erased with brushing and flossing.
Tooth discoloration also is a natural process of aging.
Tooth whitening can restore your smile.

There 2 limitations though:

- the discoloration caused by antibiotics
- artificial teeth
