Modern root canal treatment is done under local anaesthesia and usually feels similar to getting a filling. Most patients are back to normal routine the same day.
When you may need it
- Lingering pain with hot or cold food and drinks
- Throbbing toothache, especially at night
- Pain when biting or chewing
- Swelling of the gum or a small pimple on the gum
- A tooth that has turned dark after an injury
- Deep decay seen on an X-ray
What happens during treatment
- 1
Examination and X-ray
We check the tooth and take an X-ray to see the infection and the shape of the roots.
- 2
Numbing and cleaning
The tooth is numbed. Infected pulp is removed and the canals are shaped and disinfected.
- 3
Sealing
The canals are filled and sealed to stop bacteria from getting back in.
- 4
Crown
A root-canal-treated back tooth is often weaker, so a crown is usually advised to protect it.
Recovery and aftercare
- Mild soreness for a few days is normal; take medicines as prescribed.
- Avoid chewing hard food on the tooth until the final crown or filling is placed.
- Keep brushing and flossing normally.
What affects the cost
The cost depends on your examination findings. Dr. Nath explains the options and the cost clearly before any treatment begins. The main factors are:
- Which tooth is treated — front teeth have fewer canals than molars
- How severe the infection is
- Whether a crown is needed afterwards, and the crown material chosen
Common questions
Is root canal treatment painful?
The treatment is done under local anaesthesia, so most patients feel pressure rather than pain. It usually relieves the toothache that brought you in.
How many visits does a root canal take?
Many root canals are finished in one or two visits. Teeth with severe infection or complex roots may need an extra visit.
Do I need a crown after a root canal?
For back teeth (molars and premolars), a crown is usually recommended because the tooth becomes more brittle. Dr. Nath will advise based on how much tooth structure remains.
