Question
A 4-year-old child has recently started grinding their teeth at night. What could be the possible causes, and how should it be treated?
Answer
The causes of night grinding may include gingivitis, periodontal disease, and tooth decay, which require medical diagnosis and targeted treatment. Additionally, gastrointestinal disorders and indigestion may also lead to grinding, so it is recommended to adopt a diet of light and easily digestible foods, avoiding excessive or greasy foods, as well as spicy and stimulating foods. Stress, anxiety, and excessive pressure may also be contributing factors, and it is advisable to seek methods to reduce stress; in some cases, anti-anxiety or antidepressant medications may be considered. Deficiency in calcium can also be a possible factor, as calcium deficiency increases neural excitability, leading to grinding, so supplementing with calcium is necessary. At the same time, it is recommended to engage in moderate light exercise.
