It’s best to leave it up to the experts, like an endodontist or a general dentist, to determine whether you need a root canal. However, there are some common signs and symptoms that may indicate the need for a root canal. If you experience any of the following, you should schedule an appointment with your dentist as soon as possible.

Toothache

Persistent or severe toothache could indicate the need for a root canal. An intense, continuous toothache, especially when chewing or applying pressure to the tooth, could be a sign of an infected or damaged pulp within the tooth.

Tooth Sensitivity

If you experience tooth sensitivity to hot or cold, it could be caused by infection. If you feel sharp pain or sensitivity in response to hot or cold beverages/foods and the discomfort lingers after the stimuli is removed, it may indicate pulp inflammation or infection.

Tender Gums

Swollen or tender gum tissue can indicate a range of oral health issues that need addressed. Inflammation around a specific tooth or a small, raised bump on the gum near the affected tooth may suggest an underlying problem best solved with root canal therapy.

Tooth Discoloration

Sometimes, an infected tooth may change color. A tooth that has turned dark or discolored may indicate that the inner pulp is compromised, and a root canal may be necessary.

Bad Breath

An infected tooth can release unpleasant odors or tastes due to increased bacterial activity

Weakened Tooth Support Structures

Loose or wobbly teeth usually indicate a problem. An infected tooth may cause the ligaments and bone that hold the tooth in place to weaken, leading to looseness.

Issues with Previous Dental Work

Previous dental work may need repaired at some point. In some cases, poor dental work may lead to issues down the road. If you've had previous dental work (fillings, crowns) on a tooth, and it has become sensitive or painful, your dentist may investigate and determine if a root canal is needed.

Thanks for Reading!

If you’re experiencing any of these issues, make sure you make an appointment with your dentist soon. Don’t ignore these signs or attempt to self-diagnose or treat the problem. Delaying treatment for a tooth that requires a root canal can lead to further complications, severe pain, and the potential for tooth loss.
