Understanding and Managing Tooth Sensitivity

Tooth sensitivity, also known as dentin hypersensitivity, strips the joy from eating some of the most delicious treats – like ice cream! The good news is you don’t have to just deal with it. There are many solutions out there that calm those sharp nerve pains and allow you to enjoy your ice cream (or coffee).

Causes of tooth sensitivity

Teeth sensitivity commonly occurs when the soft, inner layer of a tooth, called the dentin, is exposed to the food in our mouths. 

This can cause pain or discomfort when eating or drinking hot, cold, sweet, or acidic foods and drinks. 

And on frigid winter days, it can even cause pain when simply breathing in.

The dentin can be exposed due to a variety of reasons, including:

  • Tooth decay – Also known as cavities, tooth decay occurs when bacteria in the mouth produce acid that erodes the enamel of the tooth, exposing the dentin. 

  • Gum disease. – Also known as periodontal disease, this infection of the tissues and bones that support the teeth can expose dentin. 

  • Worn tooth enamel –When tooth enamel is worn away, it exposes the softer part of your teeth. It can occur due to aging or excessive tooth brushing.

  • Tooth whitening products – These products can strip away the enamel, causing tooth sensitivity

  • Receding gums – When the gums pull away from the tooth, revealing the root, which is not protected by enamel, it exposes dentin. Causes include: genetics, brushing too hard, periodontal disease, or even a misaligned bite.

  • Teeth grinding or clenching – Also known as Bruxism, constant grinding or clenching can wear away tooth enamel. This can occur both when you’re awake and during sleep.

Managing tooth sensitivity

The best way to manage tooth sensitivity is to prevent it from occurring. Your first line of defence against it is maintaining good oral hygiene, such as brushing teeth twice a day with a toothpaste for sensitive teeth, flossing, and visiting a dentist for regular checkups and cleanings.

However, if you’re already experiencing tooth pain, dentists can help. Common treatment options include:

  • Using toothpaste for sensitive teeth

  • Applying desensitizing agents

  • Fluoride treatments

  • Dental fillings or crowns

  • Gum surgery

  • Mouth guards

Your dentist may also recommend avoiding harsh tooth whitening products.
