What is a baby dental well visit? The health of baby’s teeth are incredibly important to his early development, and by the age of 2, baby should have a full set of teeth. We invite children as early as 2 years to our dental practice for full dental evaluation, and of course younger any time a parent is concerned a baby’s mouth and oral development. We are always happy to have parents bring the under-one children with them; we love to discuss pacifier and teething advice, too!
