Root Canal & Hearing: Understanding the Connection (or Lack Thereof)

No, you cannot become deaf from a root canal. The ear and teeth are not directly connected by any nerve. The root canal is a dental procedure that involves removing the pulp, or innermost part, of a tooth. This pulp contains nerves and blood vessels that supply the tooth with nutrients. During a root canal, the dentist removes the pulp and then fills the root canal space with a material called gutta-percha. This seals off the root canal and prevents bacteria from entering the tooth and causing infection.

Although the ear and teeth are not directly connected by any nerve, there are some cases in which a dental procedure can affect the ear. For example, if a dental instrument is accidentally inserted into the ear during a root canal, this could cause damage to the eardrum and lead to hearing loss. However, this is a very rare occurrence.
