How to cure tooth decay in 4-year-old baby

4-year-old tooth decay can be remedied by oral care, diet adjustment, regular oral examination, filling treatment, root canal treatment or tooth extraction. 1. Oral care Teach your baby the correct brushing method, brush teeth every morning and evening, use fluoride toothpaste for children. Rinse after meals and develop good oral hygiene habits. 2. Dietary adjustments Limit the amount of sugar your baby eats, especially sticky candy and sugary drinks. Increase intake of fruits, vegetables and fiber-rich foods. 3. Regular oral checkups Take your baby to the dentist for regular oral checkups and cleanings. The dentist can detect problems early and provide appropriate treatment. 4. Dental fillings If the tooth decay is not serious, the dentist may choose to fill the damaged tooth. Filling can stop the tooth decay from developing further. 5. Root canal treatment or tooth extraction For serious tooth decay, root canal treatment or tooth extraction may be needed. This depends on the degree of tooth damage and your baby's overall oral health. The best way to prevent tooth decay is to establish good oral hygiene habits, regular check-ups and early treatment. Maintain good communication with dentists and develop appropriate treatment plans according to your baby's specific conditions. Parents should also lead by example and demonstrate good oral care to help your baby develop healthy oral habits.
