The nerves of a tooth are located in a vascularized connective tissue called pulp chamber in the centre of a tooth. Damage in the nerves surrounding a tooth is due to dental trauma or improper dental procedures; its aftereffects like burning sensation, numbness, and others are either temporary or permanent.
How does tooth nerve damage happen?
Unexpected dental injuries like deep cracks that extend to a tooth’s pulp chamber and constant pressure from teeth grinding and clenching expose the injured tooth’s nerve endings. Thus various external stimuli acquire a way to access the tooth nerves. They frequently strain, irritate the nerves and eventually lead to severe damage to the nerve fibres.
On rare occasions, badly executed dental operations like putting fillings close to the nerve endings, placing implant posts longer than they should be, and faulty pulp chamber closure during endodontic procedures can also damage a tooth’s nerves.
