What is the longest-lasting teeth whitening procedure? i'd like my teeth whitened, and would like to choose whichever method lasts the longest.

The : The biggest variable in tooth whitening is the patient. The answer is different from person to person.

The : The professional in office whitening systems that are light activated (uv or laser) are the best and last much longer than the otc products. Your care afterward, including diet, smoking and homecare will also play a great role in how long you new color will last.

All : All professional teeth whitening systems are essentially the same. How long the procedure lasts depends less on the treatment, and more on your lifestyle. Do you eat or drink staining foods? What is the composition of your saliva? On average you can expect your professional whitening to last from two to three years.

None: Whitening teeth is a process, and also is a maintenance for life. It likes tanning your skin, over time the tan fades and so does the whitening.

Depends: Your diet, smoking, and oral hygiene all are factors for the longevity of your whitening...
