Dental Cavities - Does a Tooth Worm Really Exist?

Published date field Last Updated:

Once upon a time, dental patients believed a toothache was caused by a tooth worm eating away their tooth from the inside out. Modern-day medical science has proven that there is no such parasite and that the concept is merely superstition based on the appearance of diseased tooth pulp, which can look remarkably similar to a worm. The invention of the microscope made it possible to examine the tooth pulp closely, and scientists have discovered that teeth contain hollow tubes located in the dentin of the teeth—which, when diseased, can give off a worm-like impression.

Dentin Tubules

The purpose of these dentin tubules is to conduct sensitivity to heat or cold from the tooth surface to the nerve, but they aren't actually the cause of any tooth damage. When the tubules are exposed, however, this often results in sensitivity or discomfort for the patient. The tubules aren't visible to the naked eye, but under a microscope you can see why people were alarmed at the thought that their teeth were full of worms!

The Real Cause of Dental Disease

Modern dentistry proves that most toothaches are caused by dental caries resulting from tooth decay, plaque and tartar. Plaque develops when bacteria build up on the surface of the teeth and irritate the gum tissue and accumulate on the enamel, and cause cavities that may expose the sensitive tooth pulp. Gum disease is also a leading cause of dental disease. According to the Indian Dental Association, Periodontitis (also called periodontal or gum disease) is a bacterial infection that destroys the supporting structures that hold your teeth in place. It is estimated that 85% of the population has some form of gum disease. Poor oral hygiene is the primary cause of gum disease.

How to Treat Dental Caries

If you discover that you have a cavity, you can forget the idea that it was caused by a tooth worm. Whatever the cause, the best way to treat dental caries is to have your dentist do a restorative treatment at the earliest possible opportunity.

These treatments could include

  • Cleaning out the decayed area and filling the tooth with a restoration
  • Pulp capping to prevent the dental pulp from dying, after being exposed
  • Performing a root canal treatment if the nerve has been exposed and affectedIf a tooth is broken down or shows signs of severe decay, your dentist might extract it and recommend replacing it with an implant or bridge.

Maintaining a Healthy Mouth

The best way to avoid the type of dental disease historically blamed on a tooth worm is to maintain a healthy mouth. You can do this by brushing twice daily with a toothpaste which repairs teeth and early gum damage, flossing daily and rinsing with an antibacterial mouthwash. Visit your dentist every six months for a check-up and have any damaged teeth examined and treated as soon as you become aware of them.Don't let superstition cloud your judgment. Get the dental care you need and practice good oral hygiene to keep your smile beautiful and your breath fresh year-round.
