Dental Hygiene Generally, dental examinations and cleanings are recommended every 6 months for children. At home, help your child brush his or her teeth as needed and encourage good oral hygiene. Common Dental Problems and Concerns One of the first dental concerns that parents face is teething. Teething can make a baby uncomfortable and cranky - but it's a normal developmental stage for a child. Dental Procedures Most children have sealants applied to their back teeth to help protect them from decay. Older children may need braces or other devices to help with teeth alignment.
