There are several common symptoms that may indicate you need a root canal. Recognizing these signs early is essential to prevent the spread of infection, which can lead to abscesses, bone loss, or tooth loss.

Key signs and symptoms include:

• Persistent Toothache: Experiencing sharp pain specifically when you chew or apply pressure to the tooth.
• Temperature Sensitivity: Lingering sensitivity to hot or cold temperatures that remains long after the stimulus is removed.
• Gum Changes: Noticing swollen or tender gums near a specific tooth, or the appearance of a recurring pimple-like bump on the gum (known as a fistula).
• Discoloration: A grayish or darkening color on the tooth itself.
• Emergency Symptoms: Severe signs of a serious infection include facial swelling, fever, or the drainage of pus.

Because these symptoms often point to nerve damage or infection, a professional dental exam with X-rays is necessary to confirm if root canal therapy is required.
