Who Is a Good Candidate for Teeth Whitening
Professional whitening is suitable for most adults with healthy teeth and gums. You may be a good candidate if you have staining from food, drinks, or smoking — and if your teeth and gums are free from active decay or untreated gum disease.
A dentist will assess your suitability before treatment. This includes checking for cavities, which can make teeth sensitive and may cause discomfort during whitening if left untreated.
Whitening may be less effective on intrinsic discoloration. In these cases, your dentist will discuss alternative cosmetic options — such as veneers or composite bonding — that may better achieve your desired result.
Whitening does not change the color of dental restorations such as crowns, veneers, or composite fillings. If you are planning any restorations, it's best to whiten first so your new restorations can be matched to your brighter shade.
