Here to help when saving a tooth is the best option
An infection or inflammation deep inside a tooth can lead to lingering pain, sensitivity and swelling.

Your root canal questions answered
Is root canal treatment safe?
Yes. Root canal therapy is a proven procedure designed to remove infection and preserve the tooth.
What is root canal treatment and why might I need it?
Root canal treatment (also called endodontics) is needed when the pulp inside your tooth becomes infected through tooth decay or damaged by an injury to your mouth. This infection may spread through the root canal system and could eventually lead to an abscess, causing a great deal of discomfort. If root canal treatment is not carried out, the tooth may need to be taken out.
Will it hurt?
The procedure is carried out with local anaesthetic, so you should feel comfortable throughout. Any post‑treatment tenderness is usually mild and temporary.
How long will treatment take?
Some treatments can be completed in a single appointment; others may require two or more visits, depending on the severity of infection.
Do I need a crown after a root canal?
Often yes, particularly on back teeth, to restore strength and prevent fracture.
What happens if I put off treatment?
Delaying treatment allows the infection to spread and can lead to more severe pain or tooth loss.
When is root canal therapy needed?
You may need root canal therapy if the pulp inside your tooth becomes inflamed or infected due to decay, trauma or repeated dental work. Untreated, the infection can cause an abscess.
What does the procedure involve?
After numbing the area, your dentist creates an opening in the tooth, removes the infected pulp, cleans and shapes the root canals, and fills them. A temporary or permanent restoration is placed to protect the tooth while it heals.
What happens during root canal therapy?
Root canal therapy involves the following:
- First, local anaesthetic will be administered to ensure no discomfort is felt during treatment.
- The tooth will be prepared with a drill, allowing access to the root canal system.
- The root canal system will be thoroughly cleaned out to remove all infection and pulp.
- The root canal system is then filled and sealed temporarily with a crown.
- The tooth is checked at a later visit and when all the infection has cleared, the tooth is permanently filled.
Root canal treatment is a skilled and time-consuming procedure and most courses of treatment will involve two or more visits.

I have been a patient at Thornton Heath Dental Surgery for over 10 years, and I can truly say this is the best dental clinic I have ever been to.
I honestly had such a great experience here! Dr. Alia Johab is amazing – she made me feel so comfortable and always takes the time to answer any worries I have.
I was treated for a cavity and the experience was excellent! The professional was very attentive, careful and made me feel very comfortable during the procedure.
I have been to different dentists in the past but my visit to Dr Alia has been life changing.
