Root Canal Treatment

What Is Root Canal Treatment?

Root canal treatment — sometimes called endodontic treatment — is a procedure to save a tooth whose inner pulp has become infected or inflamed. The pulp is the soft tissue inside your tooth that contains nerves, blood vessels, and connective tissue. When it becomes damaged by deep decay, a crack, or trauma, bacteria can invade and cause infection, pain, and swelling.

Rather than extracting the tooth, root canal treatment allows me to remove the infected pulp, clean the inside of the tooth thoroughly, and seal it to prevent further infection. The tooth is then restored, usually with a crown, and can continue to function normally for many years.

I understand that root canal treatment has a reputation for being unpleasant, but I want to reassure you — modern techniques and anaesthesia make the procedure no more uncomfortable than having a filling placed. Most patients tell me afterwards that it was far better than they expected.

When Do You Need a Root Canal?

I may recommend root canal treatment if you're experiencing any of the following:

• Severe, persistent toothache — especially pain that throbs or worsens when you lie down
• Prolonged sensitivity to hot or cold that lingers after the stimulus is removed
• Deep decay that has reached the pulp of the tooth
• A cracked or fractured tooth where the crack extends into the pulp
• A dental abscess — a pocket of pus caused by infection, often accompanied by swelling, a bad taste, or a pimple on the gum
• Darkening of the tooth — this can indicate that the pulp inside has died
• Trauma — a blow to the face can damage the pulp even if the tooth looks intact externally

In some cases, a tooth may need root canal treatment even without obvious symptoms. This is sometimes discovered during routine X-rays, when I can see signs of infection at the root tip.

Why Save the Tooth?

Keeping your natural tooth is almost always the best option. A root-canal-treated tooth, properly restored with a crown, can last a lifetime. Extracting the tooth creates a gap that can cause neighbouring teeth to shift, affect your bite, and lead to further problems down the line. Replacing a missing tooth with an implant or bridge is also considerably more complex and expensive than root canal treatment.

The Treatment Process at a Glance

Root canal treatment is typically completed over one or two appointments:

1. Diagnosis — I'll take X-rays and assess the tooth to confirm that root canal treatment is the right approach.
2. Treatment — under local anaesthetic, I remove the infected pulp, clean and shape the canals inside the root, and seal them.
3. Restoration — a permanent crown is placed over the treated tooth to protect it and restore its full strength and function.

For a detailed walkthrough of each stage, see my guide on what to expect during root canal treatment.

After Treatment

Most patients feel significant relief almost immediately after the procedure, as the source of infection and pain has been removed. Some mild soreness for a few days is normal and easily managed with over-the-counter painkillers.

I've put together a detailed root canal aftercare guide covering everything from pain management to long-term care.

Success Rate

Root canal treatment has an excellent success rate — around 95% when the tooth is properly restored with a crown afterwards. With good oral hygiene and regular check-ups, a root-canal-treated tooth can last just as long as any other tooth in your mouth.

If you're experiencing tooth pain or any of the symptoms described above, don't wait for it to get worse. Early treatment gives us the best chance of saving your tooth comfortably and effectively. Contact my practice in Carlow to arrange an assessment.
