Paediatric dentists are dedicated to the oral health of children from infancy through the teen years. They have the experience and qualifications to care for a child’s teeth, gums, and mouth throughout the various stages of childhood. Children begin to get their baby teeth ​during the first 6 months of life. By age 6 or 7 years, they start to lose their first set of teeth, which eventually are replaced by secondary, permanent teeth. Without proper dental care, children face possible oral decay ​and disease that can cause a lifetime of pain and complications. Early childhood dental caries—an infectious disease—is 5 times more common in children than asthma and 7 times more common than hay fever. About 1 of 5 (20%) children aged 5 to 11 years have at least one untreated decayed tooth.
