Best dental clinic in Adambakkam | When Do a Child’s First Teeth Erupt? Dr. Akkshaya Dental and Aesthetics | Pediatric Dentistry in Adambakkam, Chennai A baby’s first tooth is a major milestone! Most children get their first tooth between 6 to 10 months of age, starting with the lower front teeth (central incisors). Every child is different—some may begin teething earlier or later, and that's usually normal. By the age of 3 years, most kids have a full set of 20 primary teeth. Watch for signs like drooling, mild fussiness, or the urge to chew—these could mean your baby is teething. At Dr. Akkshaya Dental and Aesthetics, we recommend your child’s first dental visit by age 1, or within 6 months of the first tooth erupting. Early visits help track growth, prevent cavities, and make your child feel comfortable with dental care.
