Tooth whitening is becoming one of the more common procedures we perform routinely. Even though we pride ourselves at being prepared to be your emergency dentist in Columbus, Ohio, we enjoy the different aspects of our dental practice.

One of the most common concerns patients have when considering tooth whitening is the issue of sensitivity. While using over-the-counter products at home, many patients have experienced discomfort or increased sensitivity when trying to whiten or bleach their teeth.

Sensitivity that arises as part of a tooth whitening procedure is usually caused when gas is released by the bleaching process. If a bleaching solution is left in contact directly with the gums, especially if a person has receding gums or periodontal disease, the bleaching solution can actually chemically burn the gums. Ouch! Sometimes the bleaching solutions are absorbed into the tooth surface itself. This can inflame the tooth root, causing sensitivity.

Before beginning any tooth whitening process, you should have a thorough dental check-up. Different tooth whitening procedures are available. The common bleaching solution with a custom-fit tray is not recommended for persons who have receding gums, periodontal gum disease, leaky fillings, or other dental concerns. Laser-whitening may be better tolerated.

One of your best courses of action to avoid sensitivity issues is to have your tooth whitening procedure administered at your dentist’s office. Although the solutions used at the office are often stronger than what you take home, the dental staff can better control where it is applied and for how longer, lessening the chance for irritation and sensitivity. They have access to several desensitizing agents such as sodium nitrate, amorphous calcium phosphate, or a neutral fluoride, which can often be incorporated or alternated with some professional bleaching solutions. Your dental professionals can better advise you on your options.

Most tooth whitening processes take a few days to a few weeks to complete. If having it done at the dental office is not practical, ask your dentist about applying the solution for less time but over a longer period of time at home. It will be a slower whitening process, but it may save you from some pain and irritation.

The good news is that most sensitivity will fade in a few days after the whitening process is over. For most people, the pain is slight and the reward of having a bright, white smile is worth it. But if you have any doubts or concerns, consult with your dentist prior to beginning any tooth whitening process. We don’t want you looking for an emergency dentist in Columbus Ohio because you were too aggressive with the do-it-yourself bleaching solution.
