Signs You Might Need a Root Canal

Root canal treatment has a bad reputation but thanks to modern technology, techniques, and dental sedation, they’re now less stressful and virtually pain-free! Plus, Sullivan Family Dental offers a variety of financial options, such as our Dental Membership Plan, third-party financing through CareCredit, HSAs, and FSAs.

In this blog post, we go over a few signs that you may need root canal therapy to preserve your natural tooth.

Increased Tooth Sensitivity

A sudden increase in tooth sensitivity is a sign that something is wrong. This discomfort is likely to flare when you drink hot or cold liquids or eat ice cream. If tooth sensitivity does not improve with anti-sensitivity toothpaste, we can utilize root canal therapy to remove the irritated nerves and eliminate the cause of your discomfort.


Tooth pain can come in varying degrees, but all toothaches are cause for concern. The sensitive innermost layer of the tooth, called the pulp, consists of blood vessels, connective tissue, and nerves. An infected or damaged pulp can cause a throbbing toothache or a sharp pain when biting down or chewing. A toothache can also be accompanied by pain that radiates through your jaw, head, and neck. Root canal treatment will involve removing the compromised pulp while leaving your natural tooth intact.

Bad Breath & a Bad Taste in Your Mouth

A dental abscess occurs when a tooth infection spreads from the pulp of the tooth down into its root. It creates a pocket of pus that can leave a bitter taste in your mouth and make your breath smell. Antibiotics and root canal therapy are necessary to remove the infection, save your tooth, and keep the inflammation and infection from spreading to other parts of your body.
