The idea of rotting teeth and fall is really only half the concern when it comes to dental health of their children, or anyone else for that matter.
Children should start seeing a dentist as soon as they have teeth. If it appears that there is a problem with them coming in the first place, it might be wise to take them a check. These first teeth dentist can tell a lot about what children dental care they will need in the future. After that, your dentist should tell you when to see them for visit again to the dentist.

You can always take your children to your own dentist when the time comes your dental care, but that does not always work. Some children are not just for the average adult environment.
If you look around your community, you can see that there is a dentist only for children, and is led by someone who specializes in knowing how to get children to relax and get what you need to do done with much less effort.
What you will want to consider is you, but it's always a good idea to have them at least once a year for a check-up. What happens to the teeth is not as important as what happens when adult teeth come in, but problems with the first set may indicate that there may be problems with the second.
