Do I Need a Root Canal? Signs and Symptoms You Shouldn't Ignore
5/20/2025
Tooth pain isn't something to ignore — especially when it's persistent, sharp, or accompanied by other symptoms. It's often your mouth's way of telling you something is wrong. In many cases, this can be an indication that the inner pulp of a tooth has become infected or inflamed, meaning a root canal could be needed to relieve pain and save your tooth.
At Austin Center for Endodontics, we help patients find relief with diagnosis and precise care. Recognizing the early signs you need a root canal can help prevent more serious dental issues and allow for timely, comfortable treatment.

What is a root canal?
Root canal treatment is a dental procedure used to treat infection or damage in the inner pulp of a tooth. During a root canal procedure, your endodontist will remove the inflamed or infected tissue, clean and disinfect the inside of the tooth, and then seal it to prevent further infection. Modern root canal treatment is highly effective, often virtually painless, and helps preserve your natural tooth — allowing you to avoid extraction and maintain a healthy smile.
How do you know if you need a root canal?
If you're wondering how to know if you need a root canal, it's essential to understand the common symptoms that indicate a deeper problem. Ignoring these signs can lead to worsening infection and even tooth loss. Here are some of the most telling signs you need a root canal:
- Persistent or severe tooth pain: One of the most common root canal symptoms is ongoing or intense tooth pain. This discomfort may be constant or triggered by biting, chewing, or pressure. If the pain doesn't go away with over-the-counter remedies, it could indicate a serious infection inside the tooth.
- Prolonged sensitivity to heat or cold: If your tooth is overly sensitive to hot or cold temperatures, this could point to nerve damage that may require root canal therapy.
- Swollen or tender gums: Inflamed, swollen, or painful gums around a specific tooth may be a sign of a tooth abscess, which often requires a root canal to treat effectively.
- Tooth discoloration: A tooth that turns gray or dark compared to the surrounding teeth may be showing signs of internal damage or decay. This type of discoloration can indicate that the pulp inside the tooth is deteriorating, signaling the need for root canal treatment.
- Pain when biting or touching the tooth: Increased pain when biting down or even lightly tapping the tooth can be a sign that the inner pulp is infected. If the pain worsens with pressure, you may be a candidate for root canal therapy.
What does root canal pain feel like?
Root canal pain can vary from person to person. For some, it may feel like a sharp, stabbing pain, while others may experience dull, throbbing aches or sensitivity that won't go away. Pain may also radiate to the jaw or ear on the same side of the face. If you're experiencing persistent or unexplained dental pain, it's time to see a specialist.
Why prompt treatment matters
Delaying a necessary root canal can result in the spread of infection, damage to nearby teeth, including cracked teeth, other necessary treatments, including an apicoectomy, or even tooth loss. The sooner the problem is treated, the more likely it is that your natural tooth can be saved. Early intervention with a root canal also leads to faster healing and less discomfort.
