Symptoms of nerve infection in tooth?

Symptoms of nerve infection (pulpitis) in a tooth may include:

1. Persistent toothache: A severe, throbbing, and continuous pain that may worsen at night.

2. Sensitivity to hot or cold: The tooth may become extremely sensitive to hot or cold foods and drinks, and the pain may persist for a prolonged period after the stimulus is removed.

3. Spontaneous pain: Pain may occur without any apparent trigger and can be intense.

4. Swelling and tenderness: The gums surrounding the affected tooth may become swollen, tender, and red.

5. Difficulty biting: Biting or chewing may become painful due to the inflammation and sensitivity in the tooth.

6. Visible damage: In some cases, the tooth may show visible signs of damage, such as cracks, chips, or discoloration.

7. Bad breath and a foul taste: The infected pulp tissue can release gases and toxins that cause bad breath (halitosis) and a foul taste in the mouth.

8. Fever and malaise: In severe cases, a nerve infection can lead to a fever, general feeling of unwellness (malaise), and swollen lymph nodes in the neck.

If you experience any of these symptoms, it's important to visit a dentist as soon as possible. Prompt diagnosis and treatment of a nerve infection are crucial to prevent complications and save the tooth. The dentist may perform tests, such as X-rays or a pulp vitality test, to confirm the diagnosis and determine the extent of the infection. Treatment options may include root canal therapy, antibiotics, or extraction of the affected tooth, depending on the severity of the infection.
