Teeth Whitening Q & A

What Ingredients Are Used to Whiten Teeth?

Carbamide peroxide and hydrogen peroxide are the two most common bleaching agents used in teeth whitening systems. Baking soda, hydrated silica, potassium nitrate, and sodium tripolyphosphates are found in most toothpastes that are designed to help whiten teeth when used on a regular basis. It is important to remember that ingredients like baking soda and silica are mildly abrasive and constant use can start to wear away the delicate enamel that covers the tooth’s surface. The more the enamel is worn away or becomes damaged, the more likely it is for the patient to begin to experience sensitivity when exposed to hot or cold temperatures.

How Often Should a Person Whiten Their Teeth?

The type of whitening system used will determine how often they can be safely used without fear of damaging the tooth’s enamel. Toothpaste that contains whiteners can be used safely used a few times a week, but should not be used on a daily basis due to the mild abrasives they contain. Strips that contain strong whiteners should only be used a few times a year. Because the strips put the whitener in direct contact with the surface of the teeth, it can cause irreversible enamel loss. The whitening systems used at the dentist’s office are considered to be the safest because they are used in a controlled environment, and the patient’s progress is closely monitored at all times.

Is It Safer to Have a Dentist Perform a Teeth Whitening Procedure?

Home teeth whitening systems can contain abrasives and potent chemicals that can degrade the delicate enamel that covers the tooth. Leaving a whitener in place for too long can have a dramatic impact on the health of the teeth and may increase the risk of sensitivities to extreme temperatures. Having a teeth whitening procedure performed at a dentist’s office is the safest and most efficient way to get the best results without damaging the teeth in any way. The dentist’s office is a controlled environment where the patient is closely monitored at all times. The doctor or hygienist will evaluate the progress of the procedure to provide the patient with the best possible results.
