Why does tooth pain occur when eating sugar?

Generally, tooth pain when eating sugar may be caused by tooth sensitivity, dental caries, periodontitis, pulpitis, or hidden tooth fractures. Treatment options include routine care, medication, and root canal therapy.

1. Tooth Sensitivity: Tooth sensitivity is usually caused by damaged enamel, which leads to exposed dentin. When eating sugar, the sugar can stimulate the nerve endings in the dentinal tubules, causing pain. Maintaining good oral hygiene and avoiding sugary foods can help reduce irritation to the teeth.

2. Dental Caries: Dental caries result from poor oral hygiene, allowing bacteria to proliferate on the teeth and produce acidic substances that erode dental hard tissues. When cavities form, the sugar content in sweets can activate cariogenic bacteria, producing large amounts of acid that irritate the dentin and pulp, causing pain. Follow medical advice to use medications such as ibuprofen tablets or acetaminophen tablets to relieve pain.

3. Periodontitis: Periodontitis is an inflammation of the periodontal tissues caused by bacteria in dental plaque. Patients may experience red, swollen gums, bleeding, and possible dental calculus on the tooth surfaces. Eating sugar can irritate the local tissues, causing pain. It is recommended to follow medical advice and use medications such as minocycline hydrochloride capsules or metronidazole tablets for treatment.

4. Pulpitis: Pulpitis is usually caused by trauma, wear, or infection of the tooth structure. When the pulp becomes inflamed, it becomes sensitive to stimuli such as cold, heat, sour, or sweet substances, and eating sugar can cause pain. At this stage, follow medical advice to use medications such as roxithromycin capsules or diclofenac sodium sustained-release tablets for treatment.

5. Hidden Tooth Fractures: Hidden tooth fractures are caused by insufficient tooth hardness, structural defects, excessive biting force, or other factors leading to cracks in the teeth. When eating sugar, the sugar can seep through the cracks into the dentin or even the pulp, causing pain. In such cases, cooperate with your dentist to undergo root canal treatment to alleviate symptoms.

In daily life, develop a habit of brushing teeth regularly, use dental floss and mouthwash to maintain oral cleanliness and reduce bacterial growth. Adopt a bland diet to minimize tooth irritation and help maintain dental health.
