What are some types of teeth whitening systems?
Some teeth whitening systems consist of gel-covered strips that attach directly to your teeth. You dispose of these thin plastic strips right after use. Other systems include trays that you place a chemical mixture into, and then attach it to your teeth. They fit more like a mouthguard. The duration for which you wear the system depends on the manufacturer's guidelines.
Can I use teeth whitening products if I've had dental work?
It's important to ask your dentist before starting any kind of teeth whitening system. Only he or she can confirm which type, if any, is right for you.
How powerful of a system do I need?
If you just want to make your teeth a little whiter, start with a basic teeth whitening system. People who drink coffee or red wine or those who smoke might need a stronger system geared towards removing deeper stains.
