Teeth Whitening

Dental bleaching or whitening is a popular procedure in cosmetic dentistry.  It has effectively restored the smile of people with stained, dull, or discolored teeth. Be sure to have your teeth checked by our dentist before undergoing any type of whitening method. A child’s first teeth are generally sparkling white, thanks to their porcelain-like enamel surface, much whiter than the adult teeth that follow.  Why? Teeth can become stained by bacterial pigments, food, fluoride and tobacco. Certain antibiotic medications (like tetracycline) can also cause teeth stains. Our tooth enamel is designed to protect the teeth from the effects of chewing, gnashing, trauma and acid attacks caused by sugar. But over the years enamel is worn down, becoming more transparent and permitting the yellow color of dentin – the tooth’s core material – to show through.

What Causes Tooth Staining?

  • Age: There is a direct correlation between tooth color and age. Over the years, teeth darken as a result of wear and tear and stain accumulation.
  • Starting color: We are all equipped with an inborn tooth color that ranges from yellow-brownish to greenish-grey, and intensifies over time. Yellow-brown is generally more responsive to bleaching than green-grey.
  • Translucency and thinness: These are also genetic traits that become more pronounced with age. While all teeth show some translucency, those that are opaque and thick have an advantage: they appear lighter in color, show more sparkle and are responsive to bleaching. Teeth that are thinner and more transparent – most notably the front teeth – have less of the pigment that is necessary for bleaching. According to cosmetic dentists, transparency is the only condition that cannot be corrected by any form of teeth whitening.
  • Eating habits: The habitual consumption of red wine, coffee, tea, cola, carrots, oranges and other deeply-colored beverages and foods causes considerable staining over the years. In addition, acidic foods such as citrus fruits and vinegar contribute to enamel erosion. As a result, the surface becomes more transparent and more of the yellow-colored dentin shows through.
  • Smoking habits: Nicotine leaves brownish deposits which slowly soak into the tooth structure and cause intrinsic discoloration.
  • Drugs / chemicals: Tetracycline usage during tooth formation produces dark grey or brown ribbon stains which are very difficult to remove. Excessive consumption of fluoride causes fluorosis and associated areas of white mottling.
  • Grinding: Most frequently caused by stress, teeth grinding (gnashing or bruxism) can add to micro-cracking in the teeth and can cause the biting edges to darken.
  • Trauma: Falls and other injuries can produce sizable cracks in the teeth, which collect large amounts of stains and debris.

Methods

Three major teeth whitening options are available today. All three rely on varying concentrations of peroxide and varying application times.

Option #1: In-Office Whitening

Significant color change in a short period of time is the major benefit of in-office whitening. This protocol involves the carefully controlled use of a relatively high-concentration peroxide gel, applied to the teeth by the dentist after the gums have been protected with a paint-on rubber dam. Generally, the peroxide remains on the teeth for several 15 to 20 minute intervals that add up to an hour (at most). Those with particularly stubborn staining may be advised to return for one or more additional bleaching sessions, or may be asked to continue with a home-use whitening system. In-office teeth whitening costs $650 per visit (on average) nationwide.

Option #2: Professionally Dispensed Take-Home Whitening Kits

Many dentists feel that professionally dispensed take-home whitening kits can produce the best results over the long haul. Take-home kits incorporate an easy-to-use lower-concentration peroxide gel that remains on the teeth for an hour or longer (sometimes overnight). The lower the peroxide percentage, the longer it may safely remain on the teeth. The gel is applied to the teeth using custom-made bleaching trays that resemble mouth guards. Take-home teeth whitening kit costs $100 to $400.

Option #3: Over-the-Counter Teeth Whitening

The cheapest and most convenient of the teeth whitening options, over-the-counter bleaching involves the use of a store-bought whitening kit. This option features a bleaching gel with a concentration lower than that of the professionally dispensed take-home whiteners. The gel is applied to the teeth via one-size-fits-all trays, whitening strips or paint-on applicators. In many cases this may only whiten a few of the front teeth unlike custom trays that can whiten the entire smile. Over-the-counter teeth whitening costs $20 to $100.

Maintaining Your Teeth Whitening Results

To extend the longevity of newly whitened teeth, dentists are likely to recommend:

  • At-home follow-up or maintenance whitening – implemented immediately or performed as infrequently as once a year.
  • Avoiding dark-colored foods and beverages for at least a week after whitening.
  • Whenever possible, sipping dark-colored beverages with a straw.
  • Practicing excellent oral hygiene – brushing and flossing after meals and at bedtime.
