Did you know tooth decay is the biggest threat to your little one’s smile? Although cavities are preventable, more than half of children over the age of 6 have had at least one. Decay is the most chronic condition in America. It’s even more common than childhood asthma. Good oral hygiene habits, a healthy diet, and regular dental care can keep dental caries at bay, but is there more you could do to safeguard their smile? Studies have found silver diamine fluoride (SDF) is just as effective as dental sealants when used to protect against decay.
