Signs You Need to See a Root Canal Dentist Immediately

A root canal is a recommended procedure when patients are facing an infection of the inner tooth pulp or root. When the pulp becomes inflamed or infected, it’s not only painful, but the infection can also spread and lead to other, more serious, dental and overall health problems. If you notice the signs of an infection, you may need to urgently see a trusted root canal dentist in Whitby. At Diamond Dental Centre, our team of experienced dentists in Whitby can help you navigate the issue and provide you with tailored care that relieves the pain and protects your smile.

Here are the top 9 signs it’s time for you to see an emergency root canal dentist in Whitby.

1. Persistent Tooth Pain

Ongoing tooth pain that does not go away is one of the most common signs that something is wrong. The pain may feel deep, throbbing, or sharp, and it can worsen when chewing or applying pressure. Persistent discomfort often indicates infection inside the tooth. If you’re in serious pain, don’t wait to contact Diamond Dental Centre. Our team is available to help. We’ll take the time to understand the cause of the pain and provide you with tailored solutions that provide the relief you need.

2. Sensitivity to Hot or Cold

It is normal to experience some brief sensitivity to hot coffee or cold drinks. However, if the sensitivity lingers long after the temperature stimulus is removed, it may signal nerve damage inside the tooth, especially if the sensitivity is new to you. 

3. Swollen or Tender Gums

Swelling around a specific tooth can indicate infection beneath the gumline. The area may feel tender to the touch or appear slightly raised. In some cases, a small bump may form near the tooth, which can signal an abscess (a pocket of pus caused by a bacterial infection). Your dentist in Whitby may prescribe antibiotics as well as a root canal treatment to control and eliminate the infection and preserve your other teeth.

4. Darkening of the Tooth

When a tooth becomes darker or discoloured compared to neighbouring teeth, it is typically the result of internal damage, including when the tooth’s pulp tissue breaks down from infections or trauma. 

5. Pain When Chewing

If biting down causes sharp or lingering pain, the nerve inside the tooth may be inflamed. This discomfort often worsens over time as the infection progresses. It’s important to address pain while eating so that it doesn’t interfere with your access to nutrition and maintaining a healthy, balanced diet. When some patients experience pain when chewing, it’s common to avoid more difficult foods like apples or nuts, which have nutritional value.

6. Prolonged Bad Taste or Odour

An infected tooth can produce a persistent bad taste in the mouth or unpleasant breath. This may occur if pus or drainage from an abscess is present. Bad breath or halitosis is often a symptom of a more serious problem rather than just ineffective oral hygiene. If you’re experiencing chronic bad breath or have a persistent bad taste in your mouth, visit Diamond Dental Centre so they can take a closer look.

7. Cracked or Chipped Tooth

A cracked or chipped tooth can allow bacteria to enter the pulp chamber and can facilitate infections. Even if the crack seems minor, by creating a gateway for bacteria, it can lead to an infection that requires root canal treatment to preserve the tooth. 

8. Previous Deep Filling or Trauma

Teeth that have undergone multiple procedures or have experienced trauma are more vulnerable to pulp damage. If discomfort develops in a previously treated tooth, it should be evaluated promptly by a trusted dentist in Whitby at Diamond Dental Centre.
