Oral Infection


What is an oral infection?

An oral infection is an inflammation of the oral cavity. Oral infections are usually the result of tooth decay in the pulp of the tooth. The pulp of the tooth is a mass of connective tissue that is at the Centre of the tooth directly beneath the dentin. The pulp contains the nerves, blood vessels and connective tissues.

Once the pulp and nerves of the tooth become exposed to bacteria, an oral infection occurs.
