What You Need to Know About In-Office Teeth Whitening

dca-blog_teeth-whitening-two-women-pointing

The most popular cosmetic dental procedure in the world is professional, in-office teeth whitening. Over-the-counter systems use weaker formulas that can’t achieve the instant results possible with in-office bleaching agents. Tooth or gum sensitivity is a common side effect of whitening treatments, but professional systems include desensitizing agents to protect vulnerable tissues. Since teeth whitening treatment results are temporary, and teeth can easily accumulate new stains, many dentists recommend performing maintenance treatments at home using a less-potent product. Staining due to age, foods and beverages, and tobacco respond well to professional bleaching. Some discoloration, like that due to tetracycline use, is not helped by treatment.

Not All Patients Are Candidates for Teeth Whitening Procedures

Teeth whitening may not be a good option for patients with the following problems:

  • Severe tooth or gum sensitivity
  • Teeth that appear transparent due to age
  • Stains that are deep and resistant

The In-Office Teeth Whitening Procedure

Steps vary based on the products used, but the procedure generally includes the following:

  • A cheek retractor is inserted to expose visible teeth.
  • Gums are painted with liquid rubber or resin to protect tissues from the bleaching agent.
  • Hydrogen peroxide gel is applied to visible teeth and left on for up to 30 minutes.
  • The first bleach application is removed, and a second one is applied.
  • Teeth are periodically checked between applications to determine progress.
  • The mouth is rinsed, and shade changes are measured.

Common Professional Teeth Bleaching Whitening Systems

  • BriteSmile®
  • Opalescence® Boost
  • Sapphire™ Chairside Whitening
  • Zoom!® Whitening
  • Deep Bleaching™

Each teeth bleaching whitening system has its own advantages and disadvantages. Ask your dentist in Waldorf which products will accommodate your budget and schedule, and produce the best results for your teeth.
