Then chances are you have a nice color to your teeth, and the temptation to do something that really isn't necessary is beckoning to you.
Whitening is really just to get the teeth of people who have damaged them with smoking, over consumption of stainers like coffee, neglect, drug abuse, or prescription drug damage ... to look like ... you know ... teeth.
