Why Are My Teeth Sensitive After A Dental Cleaning?

Practicing great oral care not only involves brushing twice a day and flossing daily—it also means visiting your oral care provider for a professional cleaning every six months. While these visits usually are painless and quick, they can sometimes leave your teeth feeling sensitive, especially if you received a deep cleaning. Luckily, over time these sensations will fade and do not indicate anything serious. Here’s a look at why you have sensitive teeth after a cleaning and what you can do if this feeling lasts longer than expected.

Why Are My Teeth Sensitive After A Cleaning?

Teeth sensitivity happens when the dentin, which is the layer beneath your enamel, becomes exposed due to receding gums. Remember—your roots don’t have enamel to protect them, so anything that comes in contact with them may cause sensitivity, like dental tools. While several factors contribute to tooth sensitivity, dental cleanings are a known cause, as your dental care professional may probe your gums and use tools that contact-sensitive areas of your teeth.

Deep Cleaning

Not every dental visit will involve a deep cleaning, but your teeth may also feel sensitive afterward if you do receive this procedure. According to the University of Michigan Health Library, you may need a deep cleaning when your gums have started to pull away from the teeth and create pockets where plaque can get trapped. When your oral care provider performs this procedure, which is also known as scaling and root planing, they’ll remove tartar and rough bacteria that have calcified on your teeth in these pockets. According to the American Dental Association, scaling is when your oral care provider removes the plaque and tartar above and below the gumline using special tools. Planing is when they smooth out your teeth’s roots to help your gums reattach to your teeth. 

Before a deep-cleaning session, the gums may be inflamed and swollen or have deep pockets infected with bacteria. Both scaling and root planing help treat these problems, but this treatment can hurt your teeth after the cleaning due to natural discomfort and bleeding. The dentist may offer a local anesthetic if your deep cleaning is likely to be more irritating.

What Happens Next?

It’s normal to experience sensitivity after a deep cleaning, which can last up to a week. Soreness and pain may also linger for a few days as your gums may be swollen or bleed. Your oral care provider may prescribe an antibiotic or mouth rinse to manage any pain and fight any possible infections.
