Not all stains come out easily
If your teeth were overexposed to fluoride during your first eight years of life, you may have a cosmetic condition called “fluorosis“—white spots or fine, chalk-like lines on the surface of your teeth. These stains can be difficult to treat and may require multiple bleaching treatments to improve.
You’ll need a checkup first
Before you can get that Hollywood smile, it’s critical to have a dental exam to ensure that your mouth is healthy. “Dental problems such as cavities and gum disease need to be addressed before bleaching,” says Eric Klein, a dentist in Norwalk, CT. Here’s why it’s so important: “Teeth whitening that is peroxide-based is meant to whiten the enamel layer, not the structure inside the tooth near the nerve,” says Jennifer Jablow, a cosmetic dentist in New York City. “If the enamel is not intact, because of cavities or other damage, the whitening gel can leach into the nerves tissue and cause irreversible damage.” Don’t miss these 30 everyday mistakes you could be making that are damaging your teeth.
