A 40-year-old member asked:

how long will the laser teeth whitening stay on my teeth after i've completed the treatment?

A few months: Any whitening will begin to fade after a few months due to things we eat and drink with color in them. People who drink lots of coffee, tea, red wine, or use tobacco will see stains again after a few weeks. It usually takes non-smokers with healthy diets about 6 months to see staining. When this happens, you can use whitening trays or strips to touch up every so often.

Varies: The best way to make the result of the treatment last is to use a touch up kit following the laser.
Dr. Ashish Naik
General Practice 16 years experience
Whitening: How long your teeth will stay light will be determined by the thickness of your enamel, ph, genetics and diet. The method in which your teeth were whitened should not change the length of time the shade remains. Try touch up kits and avoiding highly acidic foods and food and drink that cause stains to teeth.

Depends: Your diet, oral hygiene, and how often you boost your whitening, etc. All play important factors in your whitening.

A member asked:

Is it true that fluoride can cause tooth discoloration in children?

Dr. Michael Coogan

Yes: Fluoride, which occurs naturally in some city water supplies, is incorporated into children's developing teeth and helps to prevent tooth decay. Many municipalities have carefully added Fluoride to their water. Unfortunately, too much Fluoride may cause discoloration of the enamel. You should speak to your pedodontist or pediatrician about the proper amount of Fluoride for your child.
Dr. Andrew Killgore

The potential systemic health consequences to our pediatric population far outweigh the benefits of strengthening enamel and caries prevention. I have attached a brief Harvard overview to reference one of many potential concerns. http://www.hsph.harvard.edu/news/features/fluoride-childrens-health-grandjean-choi/

In addition there can be potential consequences to the adult population. Some areas have naturally ocurring very heavy concentrations of fluoride in their water and flourosis or dark discoloration is common in these localities. I am a dentist but have never been in favor of medicating a total population to treat one segment-especially when they can receive the benefits of flouride in other ways.

I agree to some extent with Drs. D'Amico & Coogan, but want to add that injested (drops, pills, drinks high in fluoride, swallowed toothpaste) is difficult to control dosage that could lead to discoloration of developing adult teeth for a specific child. Discolored baby teeth is usually caused from something injested or illness of mother during pregnancy. See: http://www.888-smile.com/Ask_Dr.html

Yes: However, it is imperative that the periodontal disease (bone loss) be treated so that you are in good periodontal health and in a maintainable level of periodontal health. See a periodontist before beginning the orthodontic therapy. I can provide you with a local good periodontist via e-mail (dhschneid@gmail.Com).
