What is root canal treatment, and who is it for?

Root canal treatment removes the inflamed or infected pulp from inside the tooth's canals, cleans them and seals them — so your natural tooth can be kept and used instead of extracted. It stops the pain and the infection that could otherwise spread.

The dentist X-rays the canals before every case. A root-treated tooth is often more brittle than usual, so a crown is usually recommended afterwards to strengthen it and extend its life.

Who it's for

✓Severe toothache, pain at night or when chewing

✓Decay reaching the pulp

✓A pimple or gum swelling near the root tip

✓A tooth whose nerve died after an impact

✓Wanting to keep the natural tooth instead of extracting

Frequently asked questions

Does a root canal hurt?

It is done under local anaesthetic, so it is painless during treatment. Afterwards you may feel some tightness or tenderness for 2–3 days, which gradually eases.

How many visits does it take?

It depends on the tooth position and complexity — front teeth usually 1–2 visits, molars 2–3. The dentist estimates the number of visits before starting.

How much does it cost? Can I pay in instalments?

Front teeth 7,000–8,000 THB, premolars 9,000–11,000 THB, molars 12,000–15,000 THB (crown not included). 0% instalments up to 10 months.

Do I need a crown afterwards?

A root-treated tooth is often brittle and prone to cracking, especially molars, so a crown is recommended to strengthen it and extend its life.

Can I skip a root canal?

Leaving an infected tooth can worsen the pain, form an abscess at the root tip and spread until the tooth must be extracted. A root canal saves the natural tooth.

What is root canal treatment, and why do it?

Root canal treatment removes the infected or inflamed pulp from inside the tooth, cleans the canals and seals them — to save that tooth instead of extracting it, so it works normally again.

What symptoms may need root canal?

Severe or throbbing toothache, lingering sensitivity to hot and cold, decay reaching the pulp, a pus bump on the gum near the tooth, or a tooth that has darkened — come in for an examination and X-ray.

The procedure and how many visits

Under local anaesthetic, the dentist opens the pulp chamber, cleans and shapes the canals, then seals them. It usually takes 1–3 visits depending on the complexity and number of canals.

Why crown a root-treated tooth?

A root-treated tooth is often more brittle because a lot of tooth structure is removed. A crown caps and protects it from fracturing so it lasts longer under chewing. The dentist advises based on the remaining tooth.

Saving the tooth instead of extracting

Rather than extracting and needing a replacement, root canal keeps your natural tooth — better for chewing and bite in the long run. It is comfortable during treatment thanks to the anaesthetic.
