Professional teeth whitening
It is common for teeth to be sensitive for a few days following teeth whitening procedures, occasionally the sensitivity will last longer. Patients may describe this sensitivity as a momentary tingling or stinging sensation. To manage tooth pain, rinse with warm milk, milk will decrease your tooth sensitivity and re-mineralize (or seal) your enamel. It is also advisable to use fluoride containing mouthwash and toothpaste to decrease sensitivity.
Whitening may cause inflammation of your gums, lips or cheek margins. This is due to inadvertent exposure of a small area of those tissues to the whitening gel. The inflammation is usually temporary and will subside in a few days. To manage gum pain, just make a hole in a vitamin E capsule and squeeze a drop of oil on your gums. You may need to re-apply a few times.
Your teeth are still porous from the teeth whitening procedure and can be particularly susceptible to staining immediately following the procedure. Here are a few tips to follow for the next few days:
Avoid dark beverages such as tea, coffee, dark soda, or any colored drink. Your teeth can absorb the color for up to 3 days after your teeth whitening procedure.
Avoid staining types of food, like grapes, tomatoes, cherries, raspberries, blackberries, mustard, spaghetti sauce, soy sauce, blue berries and dark chocolate.
If you do eat any of these foods in the first couple of days after your teeth whitening treatment, brush your teeth and rinse your mouth immediately after eating.
Think of whatever would stain a white t-shirt, and that would also stain your teeth.
