Teeth Whitening Q & A

Why do my teeth look yellow and dingy?

Everyday, our teeth are exposed to foods and beverages that contain dark or deep pigments that can cause staining. Coffee, tea, red wine, dark berries, and many spices contain deep pigments, and so do foods with natural and artificial coloring. All of these foods and beverages can cause stains, especially if you also consume products like citrus fruits or energy drinks that are high in acids since these products temporarily soften tooth enamel and make it easier for stains to penetrate. Tobacco use also causes yellow and brown stains on teeth, and poor oral hygiene can also take a toll. The good news is, these issues affect the superficial layers of teeth, and they can be corrected with professional teeth whitening treatments. Some stains in the deeper layers of teeth are caused by diseases, tooth damage, or long-term use of medications. Those deeper stains need to be corrected with veneers or cosmetic bonding.

How does teeth whitening work?

Teeth whitening uses special whitening agents designed to safely penetrate the tooth surface, breaking down stains and removing them so teeth look whiter, brighter, and healthier. During in-office teeth whitening, a special soft guard is used to hold the lips back from the teeth. Dr. Sodergren or Dr. Gur-Arie will apply the whitening solution to the visible surfaces of each tooth. Once the teeth are coated with the solution, they’ll be exposed to a bright, focused light which helps the solution penetrate the tooth surface more deeply. Professional in-office whitening can be completed in about an hour, and the solution may be applied several times during your treatment to ensure it penetrates all the surfaces consistently. Take-home whitening kits use custom whitening trays designed to fit the contours of your teeth. In take-home whitening, you fill the trays with a whitening solution and wear the trays for 10-20 minutes at a time. Most take-home treatments achieve maximum effects within 10-14 days of use. take-home kits can also be used to prolong the results of in-office whitening treatments.

Can I get the same results with bleaching kits from the drugstore?

No -- drugstore kits use a one-size-fits-all approach, which means your results won’t be as dramatic or as consistent. Plus, when you have your teeth whitened professionally, tiny imperfections like fissures and cracks can be corrected first to reduce the risk of temporary tooth sensitivity.
