How white will my teeth get ?

A. Well, that depends. If you have your teeth whitened professionally in-office or at home, you can choose to make your teeth up to seven shades whiter. Your dentist will show you "shade cards" that are similar to those used for choosing paint, so you can make a decision on which is best for you.

If you use an over-the-counter product (OTC), choose carefully to ensure it is safe, effective and reliable, and follow the directions carefully. OTC products will not produce the dramatic improvements that are available through a professional. Excess exposure to OTC bleaching products can damage your teeth.

There's been a trend in recent years toward whiter, brighter teeth. The shades that were popular a few years ago seem somewhat dingy compared with the effervescent whites that many people are choosing today.

When making a decision to have your teeth whitened, it is important to think about which shade most flatters you and not how white your teeth can get. Keep in mind that your habits also dictate how white your teeth will be. Nonsmokers and people who don't drink coffee or tea will retain their whitening results much better than smokers or regular coffee or tea drinkers. Occasional touch-ups may be needed to maintain the shade you want. This must be done with professional direction.
