Why Teeth Whitening May Not Work

If teeth whitening doesn't seem to be working for you, it could be due to a variety of factors. It could be the product you're using, the type of dental stains or discoloration, or the strength of the whitening gel. Whitening toothpaste is not designed to remove deeply embedded stains. Certain foods and drinks can cause discoloration, as can smoking.

Teeth naturally yellow with age. If you have gray teeth or internal stains, teeth whitening may not be an option. People who received tetracycline antibiotics or too much fluoride as children may have gray spots that are impossible to remove with teeth whitening. Those who have had root canal therapy may also have gray teeth.

Your dentist may recommend other dental procedures, such as dental crowns or porcelain veneers.You may have tried an over-the-counter whitening product or even had professional teeth whitening treatments, but still noticed areas of discoloration in your smile. Teeth whitening doesn't work for everyone, and some people may overuse it to the point of damaging their enamel. It's important to remember that teeth whitening is safe when done correctly, but not all patients will be successful with it. Teeth that have turned gray or brown from smoking are less likely to be noticeably whitened with teeth whitening treatment.
