Teeth eroded and appear yellow

Yellow discoloration of teeth due to erosion may be caused by improper diet, poor oral hygiene habits, dental caries, chronic periodontitis, or gastroesophageal reflux disease. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified healthcare professional. Specific analysis is as follows:

1. Improper diet: Long-term consumption of high-sugar and acidic foods—such as candy and soda—can lead to erosion of tooth enamel by acidic components in these foods, gradually causing teeth to turn yellow. It is recommended to adjust dietary habits by reducing intake of sugary and acidic foods and increasing consumption of fresh fruits and vegetables such as cabbage, apples, and pears, which helps maintain oral acid-base balance.

2. Poor oral hygiene: Incomplete brushing or irregular dental cleaning may result in plaque and tartar buildup, leading to tooth decay and discoloration. It is advised to improve oral hygiene practices, including regular brushing, flossing, and professional dental cleanings, which can effectively prevent tooth erosion.

3. Dental caries: Typically caused by bacterial plaque forming on the tooth surface, these bacteria produce acidic substances that erode the hard tissues of the tooth, resulting in decay and yellowing. This condition may also be accompanied by tooth pain and swelling. Timely medical intervention with cavity filling procedures is recommended for treatment.

4. Chronic periodontitis: This is an inflammatory disease of the periodontal tissues, usually initiated by dental plaque. The bacteria involved not only cause inflammation and infection around the teeth but also promote tartar accumulation, leading to yellowing of teeth. Symptoms may include redness and swelling of the gums and bad breath. Patients are advised to follow medical instructions for treatment with medications such as ibuprofen tablets, metronidazole tablets, or penicillin V potassium tablets.

5. Gastroesophageal reflux disease (GERD): This condition may be associated with factors such as consuming high-fat foods or alcohol. After onset, stomach acid may reflux into the mouth, causing corrosion of the teeth. Prolonged acid exposure can damage the enamel, leading to yellowing. Additional symptoms may include gastric discomfort and acid regurgitation. Patients should follow medical advice to take medications such as esomeprazole magnesium enteric-coated tablets, rabeprazole sodium enteric-coated tablets, or lansoprazole tablets.

In daily life, patients are advised to drink plenty of warm water, maintain adequate sleep, and avoid spicy and irritating foods such as chili peppers and Sichuan pepper, all of which are beneficial for recovery.
