Professionally supervised tooth whitening treatments have been proven to dramatically change tooth color, making teeth noticeably whiter.
The whitening process
After an exam to ensure oral health, your dentist will determine if you are a candidate for a whitening process. There are several whitening processes available today; your dentist will recommend one that will give you the best results.
A dentist-supervised, at-home whitening system is the most popular way to achieve a whiter smile. Your dentist first takes an impression of the teeth to create a custom bleaching tray. When you receive the bleaching tray, you will also receive the whitening gel and specific instructions from your dentist on how to use the system. This system usually takes 10 to 14 days to complete but some patients may begin to notice results right away. Your dentist will ask you to come back to check on your progress.
Length of effectiveness
Depending on personal habits, whiter, brighter teeth should last one to five years. Smoking and drinking coffee, tea and dark colas can darken teeth sooner and may require a whitening touch-up. Twice-daily brushing, daily flossing and regular dental checkups will help keep whitened teeth bright.
