For most of us, our smile is the first thing others notice when they first meet us. If we want to make a good first impression, not to mention feel better about ourselves, then a whiter smile is a must.

The problem, though, is that over the years your teeth become discolored. This is part of the natural aging process, as well as a function of what you eat and drink.

Today there are numerous teeth whitening procedures that can restore your teeth’s natural brilliance and the brightness of your smile. They range from professional techniques and products that can only be employed by a dental health professional to the most basic of teeth whitening products such as whitening toothpaste. The following questions and answers are intended to aid you in your understanding of teeth whitening, how it works, and what it can do for you.

Do all my teeth start out equally white?

Interestingly, no. Your front teeth are generally the whitest naturally, followed by your molars, and then the eye teeth, which are darkest. One benefit of teeth whitening is that it helps you achieve your best smile by helping all your teeth to become white in color.

What are the causes of teeth discoloration?

The most common causes are aging, smoking, and things like coffee, tea, certain sodas, and red wine. The use of certain antibiotics during the formation of your teeth also contributes to the discoloration of your teeth.

What are some typical teeth whitening substances?

Both carbamide peroxide and hydrogen peroxide are used as whitening or bleaching agents in the teeth whitening process. They work by oxidizing the stains on your teeth and lightening their color. If they are applied over a long enough period of time, they will also bleach the dentin under the tooth’s enamel, resulting in whiter teeth.

Does teeth whitening affect dentures?

No, teeth whitening only affects your real teeth. It will not whiten dentures or caps.

Which home teeth whitening method or product is the best?

Effective home whitening products, available over-the-counter, include whitening toothpastes, strips, and trays. The least effective at home whitening method is the use of whitening toothpastes. Whitening strips are somewhat more effective, but the most effective home whitening method involves the use of whitening trays, which can be custom fitted to insure the thorough and uniform whitening of your teeth.

Why is teeth whitening not recommended for children?

No, they are not, nor are pregnant or nursing women. It has been observed that teeth whitening prior to 16 years of age can lead to certain problems later on, including nerve sensitivity issues.
