As a dental expert with extensive experience in oral health and treatment, I've encountered a variety of dental issues and procedures, including root canals. Root canal therapy is a common procedure that can save a tooth that has been damaged by severe decay, infection, or injury. Knowing when you need a root canal is crucial for preserving your dental health. Here are some signs and symptoms that may indicate the need for this dental treatment:


1. Severe Toothache: If you experience intense pain in a tooth, especially when you bite down or apply pressure to the area, it could be a sign that the pulp inside the tooth is inflamed or infected.


2. Pain and Sensitivity: Sensitivity to hot or cold that persists even after the stimulus is removed can indicate a problem with the tooth's nerve. This is because the nerve may be irritated or dying, which can be a result of deep decay or a crack in the tooth.


3. Swelling or Pimple-like Bump: An abscess, which is a sign of a severe infection, may present as a swollen area or a small, pimple-like bump on the gums near the painful tooth. This is a clear indication that the infection has spread beyond the tooth and into the surrounding tissues.


4. Discoloration of the Tooth: A tooth that has undergone significant internal damage may appear darker than the surrounding teeth. This is because the nerve and pulp inside the tooth may have died, leading to a change in the tooth's color.


5. Unexplained Pain: Sometimes, a tooth may hurt without a clear cause. This can be particularly concerning if the pain is persistent and doesn't improve with over-the-counter pain medications.


6. Fever or Glands Swollen: Systemic signs of infection such as fever or swollen lymph nodes in the neck can also accompany a severe tooth infection that requires a root canal.

7.
Pain Spreading to Other Areas: Pain that radiates to the jaw, ear, or even the head can be a sign that the infection is spreading and that a root canal may be necessary.

8.
Previous Dental Work: If you've had a crown, large filling, or other dental work and you're experiencing pain, it could be due to complications that necessitate a root canal.

9.
Cracked or Fractured Tooth: A crack or fracture in a tooth that extends to the pulp can cause severe pain and may require a root canal to treat the damage.

10.
X-ray Examination: Often, a dentist will use X-rays to examine the tooth and surrounding bone. Changes in the bone or the appearance of the tooth on X-ray can indicate the need for a root canal.

It's important to seek professional dental care if you're experiencing any of these symptoms. A dentist can perform a thorough examination and recommend the appropriate treatment, which may include a root canal if the tooth's pulp is infected or damaged.

Now, let's proceed with the translation into Chinese.
