What Is Root Canal Treatment?
A root canal treatment (RCT) is a dental procedure that treats infection deep inside a tooth - specifically within the pulp, the soft inner tissue containing nerves and blood vessels. When bacteria reach the pulp due to deep decay, a crack, or trauma, the result is intense pain and swelling.
Contrary to the common misconception that root canals are terrifying, modern techniques and local anaesthesia make the procedure comfortable - often no more uncomfortable than getting a standard filling. Dr. Ashni Shah at Akaay Dental Care is experienced in single-sitting root canal procedures, allowing you to resolve the infection and restore your tooth in as few as one or two appointments.
When Do You Need It?
You may require a root canal if you experience:
Severe, throbbing toothache that doesn't subside
Prolonged sensitivity to heat and cold
Darkening or discolouration of the tooth
Swelling or a pimple-like bump on the gum near the tooth
Pain when chewing or applying pressure
A previously treated tooth that develops recurring pain
The Procedure - Step by Step
A clinical examination and digital X-ray confirm the extent of pulp infection and the root canal anatomy.
Local anaesthesia is administered to completely numb the tooth and surrounding tissue - you will feel no pain during the procedure.
A rubber dam (thin sheet) is placed around the tooth to keep the area sterile and dry.
A small access opening is made in the crown of the tooth to reach the infected pulp chamber.
Specialised files are used to carefully remove the infected pulp and shape the root canals.
The canals are flushed with antibacterial irrigants to eliminate all bacteria.
The cleaned canals are filled with a biocompatible material called gutta-percha to seal them permanently.
A temporary or permanent filling is placed. A dental crown is recommended afterwards to protect the tooth long-term.

Aftercare Tips
- Avoid chewing on the treated side until a permanent crown is placed.
- Take prescribed antibiotics and pain medication as directed.
- Mild soreness for 2–3 days is normal; cold packs can help reduce swelling.
- Maintain regular brushing and flossing around the treated area.
- Get a dental crown placed within 2–4 weeks to protect the weakened tooth.
- Attend follow-up appointments to ensure complete healing.
