Signs You Might Need a Root Canal (And Why You Shouldn’t Ignore Them)

Tooth pain isn’t something you should ignore, especially if it lingers or worsens over time. A dull ache or sharp sensitivity could be more than just a minor issue—it might indicate an infection deep within your tooth.  

If left untreated, the problem can escalate, leading to more pain and even tooth loss. A root canal in Miramar can remove the infection, relieve discomfort, and save your natural tooth. Knowing the warning signs can help you seek treatment early and avoid unnecessary complications.

Common Signs You Might Need a Root Canal

1. Persistent Tooth Pain That Won’t Go Away

Tooth pain that doesn't go away is a strong sign you might need a root canal. The pain may start off mild but can get worse over time. It may come and go, but if it lingers or becomes very painful when chewing or putting pressure on the tooth, it's a serious problem.

This pain usually comes from deep tooth decay, an abscess, or an inflamed nerve inside the tooth. If you feel pain that spreads to your jaw, ear, or nearby teeth, that's also a warning sign. If over-the-counter pain relievers don’t help, you should see a dentist for an evaluation.

2. Sensitivity to Hot and Cold That Lingers

Feeling a quick reaction to hot coffee or ice cream is normal. However, if the sensitivity lasts more than a few seconds, it could mean nerve damage. A sharp, lingering pain when eating or drinking hot or cold items may indicate that your tooth's inner pulp is inflamed or infected.

Sensitivity from minor enamel erosion usually goes away quickly. But the pain from an infected tooth nerve continues even after the temperature changes. A root canal might be the best option if you avoid certain foods or drinks because of discomfort.

3. Gum Swelling and Tenderness Near the Affected Tooth

Swollen or tender gums around a specific tooth can indicate an infection below the surface. This swelling might come and go or stay, making it feel sore or tender when touched. Sometimes, you might see a pimple-like bump (dental abscess) on the gums near the tooth.

This abscess forms when pus collects from an infection. Sometimes, it drains, leaving a bad taste in your mouth. If swelling spreads to your face or jaw, it signals a serious infection that needs immediate care.

4. Darkening or Discoloration of the Tooth

If a tooth looks gray, brown, or darker than the others, it may have a dying nerve inside. This can happen due to trauma, decay, or untreated infections, which harm the tooth's pulp. The change in color shows that the tooth is damaged, and you may need a root canal to save it.

Discoloration from stains usually affects the surface and multiple teeth, while a single dark tooth often means nerve damage. If you also feel pain or sensitivity, it's important to visit a dentist.

5. Deep Decay or a Cracked Tooth

Cavities that reach deep into the tooth can expose the nerve, which can lead to infection and inflammation. Even if decay doesn’t initially cause pain, bacteria can go deeper and affect the pulp. A cracked or chipped tooth also raises the chance of infection by allowing bacteria to enter the inner layers.

A filling may be enough for minor damage. However, if the decay or crack is too extensive, a root canal is needed to remove the infection and protect the tooth from further harm.

Why You Shouldn’t Ignore These Symptoms

Ignoring warning signs can lead to serious problems. Infections that are not treated won't go away on their own—they can spread and cause more pain, damaging nearby teeth and bone.  

A root canal treatment removes the infection while keeping your natural tooth intact, which helps you avoid extraction and replacement. The sooner you get treatment, the easier it will be to recover.
