There are many ways to whiten your teeth; here are a few of the popular types of whitening procedures:

At Home Whitening
To keep teeth white, it’s not enough to get your teeth whitened once and expect them to stay that way. If your dentist recommends using an at home whitening kit, he will send you home with this whitening treatment with instructions to use it according to label directions. Lifestyle factors, such as smoking and excessively drinking stain-causing liquids, may require more frequent touch-ups. Speak with your dentist for more information about the at-home whitening method best suited for you.

If you are looking for a cheaper option, you could try using over-the-counter products, like whitening toothpaste, whitening strips or a whitening pen. These products are all available in supermarkets and drugstores.

Professional Teeth Whitening
For the fastest and most efficient whitening, your dentist can offer professional treatments. These in-office options contain whitening agents in higher concentrations, and produce results much more quickly than over-the-counter options. In fact, your teeth may be visibly whiter in just one visit. You also have the added benefit of a treatment that is supervised by a dental professional. Additional home whitening will be indicated with long-term success of these in-office whitening treatments.

Laser Whitening 
Laser teeth whitening is an effective way to removes stains, fast. In fact the American Academy of Cosmetic Dentistry says that laser teeth whitening can whiten a patient’s teeth up to 10 shades in about an hour. The procedure takes place in the dentist’s office so you should consult your dentist if you are interested in this procedure.
