Why does my tooth hurt when my stomach hurts?
Generally, stomach pain accompanied by toothache may be caused by factors such as mental stress, excessive fatigue, gastroesophageal reflux disease (GERD), pulpitis, and peptic ulcer. If discomfort occurs, it is recommended to seek timely treatment at a qualified hospital. The specific analysis is as follows:
1. Mental Stress
Long-term mental tension and anxiety can disrupt the autonomic nervous system, not only affecting normal gastric motility and secretion functions and causing stomach pain, but also leading to muscle tension around the teeth, resulting in tooth pain. It's important to learn emotional regulation in daily life through deep breathing, meditation, listening to calming music, and other methods to relax the body and mind.
2. Excessive Fatigue
Chronic physical exhaustion weakens immune function and affects normal gastrointestinal function, making one prone to stomach pain. Fatigue may also increase sensitivity to pain, making minor tooth discomfort more noticeable. Work and rest schedules should be balanced to avoid prolonged high-intensity labor, and ensure 7-8 hours of sufficient sleep daily.

3. Gastroesophageal Reflux Disease
In patients with GERD, stomach contents may reflux into the esophagus and even the mouth. Substances such as gastric acid can irritate the mucous membranes of the esophagus and mouth, causing stomach pain, while acid contact with teeth may lead to tooth sensitivity and pain. Treatment under a doctor's guidance with medications such as omeprazole enteric-coated capsules, rabeprazole sodium enteric-coated tablets, and domperidone tablets is recommended.
4. Pulpitis
Pulpitis refers to inflammation of the dental pulp, which causes severe pain that may radiate to the head and face, sometimes mistaken for stomach pain. Additionally, intense pain may affect gastrointestinal function, causing stomach discomfort and pain. Prompt visit to a dentist is necessary, and pain-relief medications such as ibuprofen sustained-release capsules, paracetamol tablets, and metronidazole tablets may be used under medical guidance.
5. Peptic Ulcer
Patients with peptic ulcers may experience periodic and rhythmic gastric pain, which may radiate to the head and face, including the teeth, through nerve reflexes, causing tooth pain. Ulcers may also impair nutrient absorption, reduce immunity, and indirectly affect dental health. Medications such as hydrotalcite chewable tablets, bismuth potassium citrate capsules, and famotidine tablets should be used under a doctor's guidance.
In daily life, maintaining good eating habits, eating meals regularly, and avoiding picky eating are important. Oral hygiene should be maintained, and regular dental checkups are necessary. Appropriate physical exercise should be performed to enhance physical resistance.
