What Causes Tooth Staining

Tooth staining is the most common reason why teeth become discolored. There are many sources of tooth staining that you encounter on a daily basis. Some of these are obvious, such as:

  • Coffee
  • Black tea
  • Colas
  • Dark beer
  • Red wine
  • Chocolate
  • Berries

Essentially, any dark-colored food or beverage could potentially lead to tooth staining.

But it’s not just dark-colored materials that cause tooth staining. There are some surprising sources of teeth staining that you might not identify at first. Apples, for example, can contribute to staining. Even though they start out white, they contain chemicals that turn dark on exposure to oxygen. And clear sodas, sparkling water, and white wine all contribute to staining because their acidic. This opens up the tooth enamel and allows staining molecules to penetrate and get trapped.

How Teeth Whitening Works

Teeth whitening uses a variation on peroxide to break down the staining molecules and remove them from your enamel. There are different ways we can apply the peroxide.

The simplest and most convenient method of whitening is called Whitening To Go by Opalescence.  This pre-loaded tray requires only 15-20 minutes per day for 10 days to achieve a brighter smile.  Patients also can keep a pack on hand for periodic touch ups. 

A deeper method of whitening is called Custom Home Whitening.  This involves taking impressions of your teeth to create custom trays that fit you perfectly.  You will then load these trays at home with a special gel that you will wear at night for a prescribed number of days (usually 2 weeks). The trays are then kept for future touch-up use.

Our deepest whitening system is Kor Deep Whitening. This is best for patients who are resistant to whitening or who have deeper staining.  This system involves whitening at home for 2 or more weeks and then reporting to the office for a deep whitening session.

We can assess your situation and prescribe the perfect system for your needs.

The Limits of Teeth Whitening

Teeth whitening works by removing stain molecules from your teeth, but that’s not the only reason why your teeth might look discolored. Your teeth might look discolored, ironically, because you’ve whitened them too much, such as using too many whitening strips or trays. This can thin the enamel allowing the yellowish dentin to show through.

Teeth can be discolored by defects in the enamel. They can also be discolored as a result of trauma, which is more like a tooth bruise, staining a tooth from the inside.

In all of these cases, teeth whitening won’t help. Instead, we have to use another approach to whitening your teeth, covering them with porcelain veneers or dental crowns. With eroded teeth, dental crowns are preferred because they protect your teeth.
