Root canal treatment: common myths explained

Few dental treatments carry as many worries as root canal treatment. Knowing what it is for can take away much of the mystery.

What root canal treatment is

Inside every tooth is soft tissue called the pulp, which holds nerves and blood vessels. If a deep cavity, a crack or an injury lets bacteria reach the pulp, it can become infected. Root canal treatment removes the infected pulp, cleans the inside of the tooth and seals it, so the tooth can be kept rather than taken out.

Myth: it is very painful

The pain people connect with root canals usually comes from the infected tooth, not from the treatment. You will normally have a local anaesthetic first, so the area is numb and you are awake but should feel little or no pain. If anything hurts, tell your dentist straight away.

Myth: it is always one quick visit

Some root canal treatments are finished in one or two visits and others take more, depending on the tooth. Appointments can be long. A temporary filling may protect the tooth between visits, and afterwards the tooth usually needs a permanent filling or a crown for protection. Your dentist will explain what to expect for your tooth.

Myth: taking the tooth out is simpler

Root canal treatment is used to repair and save a tooth instead of removing it. If an infected tooth is not treated, it may eventually need to be taken out, and the infection can damage the bone that holds the tooth in place. Your dentist can talk through the options for your situation, including the benefits and risks of each.

Recovery

Numbness fades over several hours. The tooth and the area around it may feel sore or sensitive for a few days. Your dentist will tell you how to ease any discomfort.

• Be careful not to bump or knock your mouth
• Go to your follow-up appointment so the tooth can be properly restored
• Keep brushing twice a day with fluoride toothpaste and clean between your teeth
• Keep up regular check-ups

With good care, a tooth that has had root canal treatment can last for many years.
