If you have mild to moderately discolored teeth that you would like to lighten, you are probably a candidate. However, there are some factors that may prevent you from being a good candidate. You may not be an ideal candidate if:
- You are a heavy smoker
- You have gum disease or significant decay
- You have sensitive teeth
Since teeth whitening can result in some tooth sensitivity, if you already have teeth that are very sensitive, you should probably not undergo the procedure. In addition, if you are a heavy smoker, you will not see long-term results. Teeth whitening can certainly lighten your teeth even if you are a smoker, but if you cannot quit smoking or reduce the number of cigarettes you smoke, your teeth will inevitably become stained again.
Gum disease and tooth decay will need to be treated before you can undergo teeth whitening. If your tooth decay is extensive, you may need a full restorative plan that includes dental crowns and fillings. It can be used to match the rest of your natural teeth to the shade of your restorative dentistry work, though.
