What causes soreness in the lower front teeth?

Generally, soreness in the lower front teeth may be caused by improper diet, dentin hypersensitivity, caries, gingivitis, or gingival cracks. A detailed analysis is as follows:

1. Improper diet: Consuming excessive acidic foods can irritate the teeth and cause tooth soreness. It is recommended to adjust the diet and reduce the intake of acidic foods. Frequent rinsing of the mouth helps minimize residual acidic substances in the oral cavity.

2. Dentin hypersensitivity: Frequently consuming overly hard foods can cause friction against the teeth, leading to exposed dentin and resulting in hypersensitivity symptoms. Avoiding overly hard foods and reducing tooth friction can alleviate tooth soreness. Additionally, under a doctor's guidance, laser therapy may be used to reduce the diameter of dentinal tubules and improve discomfort.

3. Caries: Poor oral hygiene can lead to bacterial infection, damaging dental hard tissues and forming cavities, which may cause tooth soreness. It is recommended to rinse the mouth with mild salt water to reduce inflammation and kill bacteria. If symptoms are severe, visit a hospital to have the decayed tooth removed and use dental amalgam material for filling restoration.

4. Gingivitis: Nonspecific inflammation of the gums caused by dental plaque may lead to symptoms such as gum bleeding and tooth soreness. As instructed by a physician, ultrasonic teeth cleaning can be used to remove dental plaque and reduce irritation. For more severe cases of gingivitis, medications such as metronidazole tablets, amoxicillin capsules, and cephalexin capsules may be used under medical guidance.

5. Gingival crack: Microscopic cracks in the teeth caused by structural defects, abnormal cusp morphology, excessive occlusal force, and other factors may lead to tooth soreness. Cracked teeth can be treated at a regular hospital using light-cured composite resin restoration therapy.

There are various causes of lower front tooth soreness, and treatment plans should be selected according to individual conditions. Once soreness in the lower front teeth occurs, prompt medical attention should be sought, and treatment should be followed as advised by a doctor.
