Question 1

What is a root canal treatment?

Accepted Answer

A root canal is a procedure that removes infected or inflamed pulp inside a tooth, cleans the root canals, and seals them to prevent further infection.

Question 2

Is root canal treatment painful?

Accepted Answer

Modern root canal treatment is performed under local anaesthesia and is generally no more uncomfortable than getting a filling. It actually relieves the pain caused by infection.

Question 3

How do I know if I need a root canal?

Accepted Answer

Common signs include severe tooth pain, prolonged sensitivity to hot or cold, swelling, gum tenderness, or darkening of the tooth. A dental examination and X-ray can confirm the diagnosis.

Question 4

How long does the procedure take?

Accepted Answer

Most root canal treatments can be completed in one to two visits, depending on the tooth and the severity of the infection.

Question 5

Will I need a crown after a root canal?

Accepted Answer

In many cases, especially for back teeth, a dental crown is recommended to restore strength and protect the treated tooth from fracture.

Question 6

Is it better to extract the tooth instead?

Accepted Answer

Saving your natural tooth is usually the best option. Root canal treatment preserves your bite, appearance and surrounding teeth whenever possible.

Question 7

How long does a root canal-treated tooth last?

Accepted Answer

With proper care and good oral hygiene, a treated tooth can last many years — often a lifetime.

Question 8

What happens if I delay treatment?

Accepted Answer

Untreated infection can worsen, leading to increased pain, abscess formation and potential tooth loss. Early treatment prevents complications.
