The first thing people notice when they first meet you is usually your smile. That means that whiter, brighter teeth are a must if you want to make a lasting first impression and feel better about yourself.
As we age, though, our teeth tend to discolor and darken. Certain things we eat and drink contribute to this problem as well.
Fortunately, all is not lost. Today there are many teeth whitening products and methods to help us regain our teeth's original brilliance and our formerly bright smile. These products and methods are wide ranging and include both professional and at home techniques. The questions and answers that follow are provided to assist you in choosing among the teeth whitening options available today.
Do all my teeth start out equally white?
No. Generally the teeth in the front of your mouth are the whitest, followed by the molars, and then the eye teeth. As a result of teeth whitening, all your teeth can achieve a uniform degree of whiteness.
What causes darkening and discoloration of teeth?
Usual reasons for teeth discoloration include aging, drinking beverages such as coffee, red wine, some sodas and tea, and smoking. Occasionally, taking certain antibiotics while your teeth are being formed will also lead to discoloration.
What are some typical teeth whitening substances?
The whitening agents (also known as bleaching agents) used in most teeth whitening procedures are typically peroxide based and usually contain carbamide peroxide or hydrogen peroxide. They work in one of two ways: first of all, they lighten the color of the stains on teeth by oxidizing them; and, secondly, over a longer period of time they produce whiter teeth by penetrating the enamel of the teeth and actually bleaching the dentin underneath.
Can teeth whitening brighten my dentures?
No. Neither dentures nor caps are affected by teeth whitening. Only your real teeth will benefit from the procedure.
What are the best home teeth whitening products?
There are many home teeth whitening methods employing various over-the-counter products such as whitening toothpastes, whitening strips, and whitening trays. Without question, the best results are achieved with custom fitted bleaching trays. Whitening toothpastes are least effective, and whitening strips are somewhere in between in their effectiveness.
Are children candidates for teeth whitening?
When performed on children who are under 16 years old, teeth whitening can cause problems such as an increase in nerve sensitivity. Teeth whitening is also not recommended for women who are pregnant or nursing.
