How does teeth whitening work?

There are two basic types of teeth whitening. How they work depends on whether you use a professional take-home kit or choose a professional cleaning done right here in our Vinton dental office.

Professional Take-Home Whitening Kits – As the name implies, professional take-home whitening kits can be used at your pace in your own home. Simply place the prescribed whitening gel in the custom-made trays for the required time each day.

Take-home whitening kits supplied by your dentist provide whitening results far superior to those achieved using kits purchased at your local grocery store. The professional kit your dentist supplies contains bleaching gel with a higher concentration of whitening agent than that found in over-the-counter kits. A professional take-home whitening kit also includes a custom-made tray that ensures complete contact with all surfaces of your teeth for even and consistent results.

Normally the trays are worn for 15 or 20 minutes a day for about two weeks for best results. Your Vinton dentist will instruct you on the proper way to use the kit to achieve the desired results.

Professional Teeth Whitening – The main advantage of professional whitening done here at the office is that it can be done in one appointment in less than an hour. Your dentist applies a special gel to your gums to protect them from the whitening agent.

A special light is then used to "cure" the gel to achieve the best results. Professional teeth whitening can lighten your teeth by about six to eight shades. Results with home whitening are comparable, but take longer to achieve.
