Teeth bleaching removes yellowing & staining caused by aging, smoking, or food/drink. It’s done in 1-2 dental visits using gel/solution activated with light/laser.
You can whiten your teeth either at home or at a dental clinic. The home method uses toothpaste while the professional method is done by a dentist. Tests show that home teeth whitening has less impact than the professional method.
Avoid cold/heat, colored foods/beverages & follow doctor’s diet during treatment. Examples of coloring agents: cigarettes, tea, coffee, chocolate, cherries, tomato paste, & wine. Neglect=whiteness fade & tooth returns to original hue.
Bleaching can improve teeth appearance, but it has risks. Dentists don’t bleach teeth for patients under 16, pregnant women, or those with sensitive teeth, allergies, or gum disease. See a dentist before any dental procedure, including teeth whitening.
