Teeth Whitening Q & A

Mark C. Beal, D.M.D. & Associates

What causes tooth discoloration?

Despite the best oral hygiene practices, teeth can become stained and discolored over time. Two factors typically cause tooth discoloration: enamel and dentin.

Enamel is the protective surface that covers your tooth. Beneath this hard, clear surface is a yellowish interior called dentin. Physical changes occur as you age, including the thinning of your tooth enamel. This thinning allows the dentin to become more pronounced.

Stained enamel can also be the cause of your tooth discoloration. Common causes of staining include:

  • Tobacco use
  • Coffee and tea
  • Soda and red wine
  • Foods like pasta sauce


High blood pressure medications and antihistamines can also cause tooth discoloration. It’s also possible for certain medications to pass from mothers to their babies, causing teeth to be discolored in adulthood.

How does Opalescence® whiten teeth?

Dr. Beal and his associates offer a wide range of prescription-strength Opalescence Tooth Whitening Systems to accommodate every lifestyle and budget. These treatments are stronger and more effective than over-the-counter products and are administered under your dentist’s supervision to guarantee optimal results.

Opalescence products use a specially formulated hydrogen peroxide gel that contains potassium, nitrate, and fluoride. This chemically activated gel is designed to brighten teeth from the inside out, penetrating the enamel to remove stubborn stains. Its unique formula is thick and gummy, keeping the gel in place for continuous whitening.

Take-home Opalescence products work in as little as 30 minutes per day or overnight. In-office treatments using Opalescence Boost take approximately one hour.

To provide the most comfortable fit, Dr. Beal or his associate creates your personalized trays from digital impressions made from your mouth.
