Like everything else your child does for the first time, the first visit to the dentist can be very important in shaping subsequent attitudes. So it's important to make sure the first visit is a successful one.
Start by preplanning. Don't wait for an emergency. When you call to make an appointment, be sure to let us know that it is your child's first time. Usually an introductory visit simply involves letting your child sit in the 'special chair', getting to know each other, and possibly having their teeth polished.
Be careful not to communicate any anxiety to your child. Please don't mention the possibility of discomfort (because there will not be any), or even say things such as 'It won't hurt'. Instead, just tell your child something like 'We'll be visiting the dentist. You'll get to sit in a special chair and help the dentist count your teeth. And the dentist will tell you how to keep your teeth healthy.'
What's the best age for a first visit? Generally around age three. Of course, we would want to see any child who you suspect has cavities or who has had an accident that injured a tooth. But the best idea is to schedule the first visit early, before your child has a toothache, accident, or any type of dental problem.
