• Poor enamel or decalcification is caused by excessive use of fluorides.
• Periodontal disease, including gingivitis or gums in poor condition.

Hydrogen Peroxides are proven effective for removing the most common stains caused by lifestyle habits (red wine, coffee, tea, tobacco, etc.). However, other types of stains, such as those caused by tetracycline, certain antibiotics, and excessive fluoride, may also cause tooth discoloration and may be more difficult and possibly unable to whiten.

Artificial dental work such as crowns, bonding, caps, veneers, bridges, or composite fillings will whiten but will not get any whiter than when they were first put in. Artificial teeth will not be damaged or affected by the peroxide. In general, results will vary from customer to customer depending on their enamel and its reaction to peroxide.

Whitening treatments result in minimal to no sensitivity. Mild tissue (gum) irritation (a tingling sensation) may occur during the whitening process, but this occurs during the procedure and subsides completely shortly after finishing the treatment. If sensitivity persists, use toothpaste developed for sensitivity.

This is called “blanching.” It occurs in many people, is completely normal, and will subside within 5-20 minutes.

Possible white spots or demineralization may appear on people with braces or porous enamel, but this will disappear within 24 hours.

Your teeth will typically whiten 2-8 shades with a single treatment. The end result is primarily based on genetics—some people have naturally whiter teeth than others, so results of 4, 5, or 6 shades whiter can typically be achieved with a single treatment. Additionally, some people with more discolored teeth or compacted stains (due to older age, bad habits, and medications) will have to follow up with additional treatment.

In theory, results can last up to a year. Depending on a person’s consumption of coffee, tea, red wine, colas, and other darkening agents such as tobacco, most people could probably use another session 6 months later.
