Baby teeth can get cavities and it's important the cavity be caught early because enamel, especially on the front teeth is very thin. Getting a filling is a safe, normal dental procedure that will restore your child's tooth and prevent further tooth decay. But won't they just fall out? Cavities in baby teeth progress quickly and if not addressed can cause your child pain and could affect the developing permanent tooth.
