Professional teeth whitening can be customized for each person. Your dentist can adjust the treatment by changing the level of the bleaching agent used. If he uses a higher level your teeth will be much whiter. If you are looking for just a small change he can use a lower level. Deep stains can be removed with a professional procedure. Home treatments cannot penetrate enough to address those deep stains so you may have an uneven or blotchy finish. Many people feel more confident after having their teeth whitened. They tend to smile wider and more often. You achieve that white smile much quicker with a professional whitening. There are take home kits your dentist can give you that will take several weeks to meet your goal level of whiteness.
