Tooth pain is one of the most common dental problems people experience. It can range from mild sensitivity to severe, throbbing discomfort that affects eating, sleeping, and daily activities. Understanding what causes tooth pain and when to see a dentist can help prevent serious oral health complications.
What Is Tooth Pain?
Tooth pain, also known as a toothache, occurs when the nerves inside or around a tooth become irritated or infected. The pain may be constant or intermittent and can worsen when chewing, biting, or consuming hot or cold foods.
Common Causes of Tooth Pain
1. Tooth Decay (Cavities)
Tooth decay is the leading cause of tooth pain. Bacteria produce acids that erode the enamel and dentin, eventually reaching the tooth’s nerve.
Symptoms of tooth decay include:
- Sharp pain when eating sweets
- Sensitivity to hot or cold foods
- Visible holes or dark spots on teeth
2. Gum Disease (Gingivitis or Periodontitis)
Gum disease causes inflammation and infection of the gums, leading to pain and tenderness around the teeth.
Signs of gum disease:
- Bleeding gums while brushing
- Swollen or receding gums
- Persistent bad breath
3. Tooth Infection or Dental Abscess
A dental abscess is a serious bacterial infection that forms at the root of a tooth or in the gums. This condition requires immediate dental treatment.
Symptoms include:
- Severe, constant tooth pain
- Facial or jaw swelling
- Fever and bad taste in the mouth
4. Tooth Sensitivity
Tooth sensitivity occurs when enamel wears away or gums recede, exposing the dentin layer.
Common triggers:
- Hot or cold drinks
- Sweet or acidic foods
- Brushing or flossing
5. Cracked or Broken Tooth
A cracked tooth can expose the inner layers of the tooth, causing pain when biting or chewing.
Warning signs:
- Pain when chewing
- Sudden sensitivity
- Swelling around the affected tooth
6. Impacted Wisdom Teeth
Wisdom teeth that fail to erupt properly can cause pain, infection, and swelling.
Symptoms include:
- Pain at the back of the mouth
- Swollen gums
- Difficulty opening the mouth
7. Teeth Grinding (Bruxism)
Grinding or clenching teeth, especially during sleep, can wear down enamel and cause tooth and jaw pain.
Signs of bruxism:
- Morning jaw pain
- Headaches
- Worn or flattened teeth
When Should You See a Dentist for Tooth Pain?
You should schedule a dental appointment if you experience:
- Tooth pain lasting more than 24–48 hours
- Severe or worsening pain
- Swelling in the face, gums, or jaw
- Fever along with tooth pain
- Pain while chewing or biting
- Sensitivity that doesn’t go away
- A cracked, broken, or knocked-out tooth
Ignoring tooth pain can lead to infections, tooth loss, and more expensive treatments.
How a Dentist Treats Tooth Pain
Depending on the cause, your dentist may recommend:
- Dental fillings
- Root canal treatment

- Dental crowns
- Night guards for grinding
