Does whitening the teeth cause sensitivity?

Teeth whitening can cause sensitivity both on the teeth and gums. Sensitivity can be triggered by both hot and cold food and drinks, by being touched, and even by drinking and eating foods with sugars or acids within them.

Why does it cause sensitivity in the teeth?

Teeth whitening typically includes strong chemicals which can agitate the nerves when permeating through the enamel of the tooth. If the product is not confined to the surface of the tooth and seeps onto the gums or the cheek, it can cause sensitivity.

Patients with existing sensitivity may find that whitening exacerbates the sensitivity, if this is the case there may be some method you can use to reduce the discomfort caused by the whitening process.

Brushing the teeth after whitening treatment should be done gently, this ensures the nerves aren’t agitated.

How long does tooth sensitivity last after whitening?

Each patient may experience a different duration of sensitivity with their teeth, though it should normally subside after 48 hours. Patients experiencing sensitivity for weeks or months should use steps to reduce sensitivity at home. If these techniques do not reduce the discomfort, contact the dentist for a check-up to ensure there is no underlying cause.

Ways to manage tooth sensitivity?

There are various products available to buy which are designed to reduce pain and strengthen the enamel. Patient are advised to adjust their diet for the following 48 hours after treatment to ensure the strength and colour of the teeth is maintained for optimal results.

  1. When drinking avoid soft drinks, hot or icy drinks and alcoholic beverages. If you cannot completely cut these out, then try to use a straw as this directs the fluid toward the back of the mouth away from the treated teeth preventing any staining or sensitivity.
  2. Using toothpaste for sensitivity containing fluoride and desensitising chemicals can help numb and strengthen the tooth.
  3. Some dentists may apply a fluoride varnish to the teeth. The varnish typically lasts 3-6 months and is great at strengthening the enamel. It also helps prevent decay which is another great benefit of this product.
  4. Taking paracetamol or ibuprofen can help reduce the pain caused by the sensitivity. This can also reduce inflammation, so if patients who already experience sensitivity are concerned about the potential discomfort of treatment, they can take the advised dose of medication to help reduce any potential sensitivity.
  5. Buying a soft bristled brush can help ensure the teeth are brushed gently, so as not to be abrasive on the weakened enamel.
  6. Using a mouthguard whilst playing sports prevents any damage to the teeth but will also reduce the likelihood of sensitivity caused by stimulus. A night guard will help shield the teeth during sleep from any griding or clenching.
  7. Using a fluoride mouthwash can be beneficial after eating, as it can clean the mouth and strengthen the teeth.
