Some children outgrow it, but if it develops into a habit as she grows up, it can cause a lot of problems for her, such as TMJ. Ask your dentist what you can do about it; some would prescribe a mouth guard to prevent teeth grinding.

According to experts, when choosing a toothpaste for a child, parents should remember a few things:


*Choose a non-abrasive toothpaste because it can damage the enamel.
*The fluoride level should be low, especially if the child is too young to learn to spit out the toothpaste.
Get toothpaste in flavors that they will like, because adult toothpaste may be to strong for their liking.
Make sure that it doesn’t contain sodium lauryl sulfate (SLS) because it causes canker sores.

Children who are active in sports are also vulnerable to mouth injuries, especially if they do not wear mouth guards. In such cases, it is important to know the steps to take in case a dentist cannot be reached right away.

If your tooth has been knocked out:

* Rinse the tooth with clear water.
* If possible (and if you’re alert), gently put it back in the socket or hold it under your tongue. Otherwise, put the tooth in a jar with milk or wrap in a wet cloth.
* If the gum is bleeding, hold a gauze pad, a clear handkerchief, or a tissue tightly in place over the wound.
