Sensitive teeth can be caused by a variety of reasons ranging from cavities to tooth whitening products. Depending on the type of sensitivity you’re experiencing, the treatment options will vary.
When a tooth is sensitive to sweet foods or drinks, it typically indicates an area of tooth decay. Most healthy teeth are not sensitive to sweets. Even if the symptoms seem to go away, be sure to see your dentist for an exam and X-ray to identify the location of the cavity.
Heat sensitivity usually indicates nerve damage inside of the tooth. It may be that the tooth is cracked or abscessed because of a past injury or untreated area of tooth decay. Unlike cold sensitivity, heat sensitive-teeth typically require immediate treatment. Endodontic therapy will address the source of the infection and help prevent the need for an extraction.
Do your teeth feel sore or sensitive when you bite down or chew? Sore ligaments around the roots of your teeth may be due to a traumatic injury or periodontal disease. In some scenarios, sore upper teeth are also linked to swollen nasal sinuses and sinus infections. Cracked teeth may also respond to biting pressure abnormally, so an X-ray or bite check will be needed for a firm diagnosis.
Cold temperatures can easily cause tooth sensitivity, even in healthy teeth. However, issues like gum recession and exposed root surfaces can leave teeth especially hypersensitive, due to the lack of a protective cover. While fluoride or sensitivity toothpaste may help some, they will not address the issue of receding gum tissues caused by periodontal disease.
If you’re experiencing symptoms of chronic tooth sensitivity, seeing a periodontist is an excellent step in preventing additional complications like tooth loss.
