What should be done for a child's toothache caused by dental caries?

When children experience toothache due to dental caries, parents can take the following measures: 1. If the pain is mild, try applying a clean, cool, damp towel or ice pack to the affected area to help alleviate discomfort. However, avoid direct contact between the ice and skin to prevent frostbite. Additionally, adjust the child's diet to avoid excessive consumption of sweets or cold foods, which may further irritate the tooth. 2. If the pain is severe, seek prompt medical attention. Under the guidance of a physician, anti-inflammatory and pain-relieving medications may be used to alleviate symptoms. Please note that medications only offer temporary relief and cannot cure dental caries. 3. Depending on the severity of the decay, the dentist may recommend fillings or root canal treatment. Fillings involve using dental materials to seal the cavity and prevent further progression of the decay, while root canal treatment involves removing infected pulp tissue to eliminate infection and preserve the tooth. Parents should schedule regular dental checkups for children to detect and treat dental caries promptly.
