Teeth whitening procedures can help you get back that bright smile and consequently help you gain confidence. But before you book that appointment to get your teeth whitened, here are a few facts you really should know about the procedure.
Whitening and Cleaning are different procedures
Dental cleaning usually refers to a procedure where the dentist will professionally clean your teeth and gums to eliminate plaque and tartar. Whitening usually involves a chemical procedure that basically bleaches your teeth to remove staining.
Whitening involves the use of chemicals
Teeth whitening is done using a group of compounds such as carbamide peroxide and hydrogen peroxide. When these compounds get in contact with the teeth, they release radical oxygen that penetrates the outer layer of the teeth and oxidize the colour giving teeth a whiter appearance.
Whitening is not permanent
The effects of this procedure generally last from one year to three years. After this time, you need to have the procedure done again. To get the results to last longer, you should avoid certain foods such as tea and coffee or habits such as smoking that can stain your teeth.
The Procedure can be fast or slow
If the treatment is done at the dentist’s office it can take no more than 1 hour. When done at home, it may take up to 2 weeks to get the desired results.
