What Patients Ask: Teeth Whitening FAQs

What causes teeth to stain and discolor?

Extrinsic stains occur on the surface of tooth enamel and are generally caused by dark foods and beverages, tobacco use, and aging. Intrinsic stains occur within the tooth, within the enamel. They’re caused by issues like fluorosis (white, horizontal lines), tetracycline stains (bluish gray), or damage to a tooth’s nerve (tooth turns dark). Topical teeth whitening, whether over-the-counter or dentist prescribed, can reduce or eliminate surface stains. Not all stains react to teeth whitening in the same way, so having a dentist oversee your treatment helps yield optimal results. 

How is professional, dentist-managed teeth whitening different from store-bought whitening products?

Great question! If you go to the drug store and purchase a whitening paste, rinse, or strips, they may erase your dental stains. However, the concentration of active ingredients is less than what Miracle Dental recommends for tough dental stains and lasting results. Our whitening gel is specifically formulated for dentist-overseen whitening treatment. It’s simply stronger and more effective, without being harsh on teeth and gums. 

PRO TIP: Studies show that dentist-supervised teeth whitening tends to yield results several shades lighter than over-the-counter whitening products. 

Is teeth whitening really safe?

Before you begin a whitening program, your Vegas dentist will thoroughly evaluate the health of your gums and teeth. If your oral tissues are strong and healthy and you attend regular checkups and cleanings, you’re probably a great candidate for professional teeth whitening. 

How long do teeth whitening results last?

Your whitening results may last months or even years. Longevity depends upon many factors, including but not limited to:

  • Your tooth enamel’s coloring and thickness
  • Tobacco use
  • How frequently you eat dark foods and beverages
  • Home hygiene habits

Will whitening brighten my crowns, fillings, or porcelain veneers?

Chemical teeth whitening does not work on dental fillings, crowns, bridges, and veneers. It’s only effective on natural tooth enamel. If dental work in the front of your mouth shows when you smile, talk with your Vegas dentist about replacing the old dental work after whitening your teeth, so the new restorations will match your bright smile.

Who’s not a good teeth whitening candidate?

You may not immediately be a good whitening candidate if you:

  • Have poor oral health
  • Have receding gums
  • Have intrinsic stains
  • Have significant tooth sensitivity
  • Are pregnant or a nursing mother
  • Need very long-lasting (a decade plus) whitening results without retreatment
