Signs You Might Need a Root Canal

05/02/2025

A root canal is a common dental procedure that treats infection or damage inside a tooth. While the idea of a root canal can be daunting, it is often the best way to relieve pain and save a natural tooth from extraction.

Recognising the early signs of a problem can help you seek treatment before the issue worsens. Here are some key signs that you might need a root canal.

Persistent Tooth Pain

One of the most common indicators that a root canal may be necessary is ongoing tooth pain. This discomfort may be constant or come and go, but it often worsens when eating, drinking, or applying pressure.

The pain can also radiate to the jaw, face, or other teeth, making it difficult to pinpoint the exact source of discomfort.

Sensitivity to Hot and Cold

If you experience sharp pain or lingering sensitivity when consuming hot drinks, cold foods, or even breathing in cold air, it could be a sign of nerve damage inside the tooth.

This type of sensitivity often lasts longer than a few seconds and can be a warning that decay or infection has reached the inner pulp of the tooth.

Swollen or Tender Gums

Swelling or tenderness in the gums near a painful tooth could indicate an infection. You may also notice a small, pimple-like bump on the gums (known as a dental abscess), which can release pus and cause a bad taste in your mouth.

If left untreated, the infection can spread and lead to more serious complications.

Discolouration of the Tooth

A tooth that appears darker than the surrounding teeth may be a sign of internal damage. Discolouration can occur when the nerve inside the tooth dies due to trauma, decay, or infection.

This is often a sign that a root canal may be needed to remove the damaged tissue and prevent further issues.

Pain When Chewing or Touching the Tooth

If biting or applying slight pressure to a tooth causes discomfort, it could be a sign that the tooth’s nerves are inflamed or infected. This pain may start off mild but can worsen over time if the underlying issue is not addressed.

A Cracked or Damaged Tooth

A tooth that has been cracked or fractured can allow bacteria to enter the pulp, leading to infection. Even if the damage seems minor, it is important to have it assessed by a dentist, as deeper fractures can compromise the health of the tooth.

When to See a Dentist

If you are experiencing any of these symptoms, it is important to visit your dentist as soon as possible. Early intervention can help save the tooth, relieve pain, and prevent the infection from spreading.

A root canal may sound intimidating, but modern techniques ensure the procedure is as comfortable and painless as possible.

Ignoring these signs can lead to more serious dental problems, including tooth loss, so it’s always best to seek professional advice if you have concerns about your oral health.
