It's recommended to schedule your child's first dental visit by their first birthday or when their first tooth appears, whichever comes first. This helps child to get familiarised with dental check-up. If you wait till, they have cavities or pain, they may develop life-long phobia and avoid Dentist. Prevention is best and most gentle way for children and would make their dental visit very fun and pleasant.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
