Q: My teeth are stained from tetracycline use. Can teeth whitening help?
A: Unfortunately, most teeth whitening systems aren't effective on teeth with tetracycline stains. In some cases, repeated professional tooth whitening treatments can make some difference, but the results may be negligible. Porcelain veneers, which cover stained, crooked, gapped and chipped teeth, may be the best way to get white teeth instantly.

Q: How do I choose between at-home tooth whitening and professional tooth whitening?
A: It all depends on your budget, your goals and, to some degree, your lifestyle. For folks on a budget, the best cosmetic teeth whitening option may be a take-home system. With do-it-yourself kits, whitening teeth can be done while watching TV or anytime you have a free hour. Results take a little longer and may not be as dramatic, but take-home kits are, nonetheless, convenient, effective and inexpensive! If you want to make a dramatic change to your teeth, laser whitening is ideal. Performed by a dentist, chairside laser teeth whitening has the added bonus of safety and superior results. It's perfect for a special event or a special treat for yourself or a loved one!

Q: Does teeth whitening hurt?
A: If you have sensitive teeth, you could experience some discomfort during and after a laser teeth whitening treatment. Over-the-counter cosmetic teeth whitening kits, or take-home systems administered by a dentist, can also cause some sensitivity. Now your dentist can give you “Tooth Moose” to apply on your teeth 1 week before and after teeth whitening to prevent sensitivity. The safest bet is to talk to your dentist beforehand; he or she can help you decide whether to go for it and which system is right for you.
