It is best to start children getting used to going to the dentist when they are young. Also, if there is a problem developing it will be better for the child and you as the parent if the the problem is caught early on.
Children
are very impressionable. It is therefore very important to only
leave them with good impressions of whatever it is they are doing.
The power of suggestion not only works in adults, it works equally well
if not better in the young child. When talking to your kids about
the dentist, always use it in a good context, not something bad and
horrible. This way your child will be more comfortable which makes
them enjoy their dental visit rather than fear it.
