Under many dental insurance plans bleaching or teething whitening may not be covered, since many dental insurance plans will not provide benefits for cosmetic services.
Bleaching or teeth whitening can be normally be performed by your dentist in the their office or under dental supervision, at home.  Generally your dentist will create a custom mouthpiece to ensure the correct amount of whitening solution is used and that your teeth are properly exposed. Typically, whitening at home takes two to four weeks, depending on the desired shade you wish to achieve. Whitening in the office may call for one or more 45-minute to one-hour visits to your dentist’s office.
