Root Canal Treatment and a Dead Tooth: What to Know

A common misconception we hear at Georgian Mall Family Dental is that once a root canal is complete, the tooth is entirely “dead” and will eventually just crumble away.

However, we want to share a lesser-known biological reality: while the tooth loses its internal nerve sensation, it remains highly functional and stable. Below, we break down how external supporting structures make all the difference. 

The Periapical Connection

During a root canal, we remove the inflamed nerve and blood supply from the inside of the tooth. However, the outside of your tooth root is still entirely cradled by a living tissue called the periodontal ligament.

Because the external ligament remains completely alive and packed with blood vessels, your body does not reject the tooth. You will still feel the normal pressure of chewing, and your jawbone will continue to recognize the tooth root. The periapical connection prevents the bone loss that normally happens when a tooth is lost. 

Is Enamel Brittle After a Root Canal?

Because the internal blood supply is removed, the tooth does lose its internal moisture source over time. Therefore, the remaining enamel will be more brittle and prone to structural fracturing under heavy chewing forces.

A root canal is only half the battle, as we must also reinforce the tooth’s architecture from the outside. That is why a custom porcelain crown is almost always required after a root canal on a back molar. The crown acts like a metal band around a barrel, holding the remaining tooth structure together and absorbing the vertical forces to keep the tooth intact. 

Retain Dental Function with Root Canal Treatment

While root canal therapy can’t keep it fully “alive” it can still allow you to keep the tooth in place and functional. Whenever possible, we aim to save your natural tooth, which is why regular dental exams are so important. Our team uses modern technology to identify deep tooth issues for prompt treatment.
