A root canal is a dental treatment used to save a tooth when the soft tissue inside it, called the pulp, is inflamed or infected. Modern treatment is designed to remove the source of infection, protect the tooth, and help you return to normal function.
1. A root canal treats the inside of a tooth
Deep decay, a crack, repeated dental work, or an injury can allow bacteria to reach the pulp. During treatment, a dentist or endodontist cleans the inside of the tooth and seals it to help prevent another infection.
2. Pain is a reason to get checked, not a diagnosis
Lingering sensitivity to hot or cold, swelling, pain when biting, or a pimple-like bump on the gums may signal a problem. Some teeth need prompt treatment even without severe pain, so an exam and X-rays are important.
3. Numbing makes treatment manageable
Local anesthetic is used to keep you comfortable. People often compare the experience to receiving a filling. If dental anxiety is a concern, tell the team before your appointment so options can be discussed.
4. A crown may be recommended afterward
Back teeth often need a crown after root canal treatment because they handle substantial chewing pressure. Your dentist will explain whether a filling, crown, or another restoration is appropriate for your tooth.
5. The tooth still needs daily care
A treated tooth can last many years with good home care and regular checkups. Brush twice daily with fluoride toothpaste, clean between teeth, and schedule routine visits.
When to seek care
Contact a dentist promptly for facial swelling, a fever, severe tooth pain, or trouble swallowing or breathing. Those symptoms can require urgent evaluation.
