Don't worry: Plenty of kids grind at night. They usually outgrow it. Wear on the baby teeth is less alarming since they will fall out when the permanent ones come in. With a palatal expander, the occlusion will change and hopefully improve. If they don't, then the expander is not working. Sounds like you may want to talk to your sons orthodontist to get a better idea of what to expect from treatment.

Dont worry yet: The purpose of a palatal expander is to create more room to move teeth to their proper positions. Once the space is created, the orthodontist will put wires on the teeth to ensure that they move to the correct occlusion--especially the permanent molars. The jaws on a 7 year old is expanding and still growing. Permanent molars are the size they are going to be 20 years from now.

Don't worry: Grinding in children is normal. Often when using palatial expander a the teeth won't line up. It will be addressed in the next phase of treatment.

If your son snores then you should have tonsils and adenoids evaluated by doctor

Don't worry: He's a work in progress. For successful correction of side-to-side problems expansion is quite common, and often slight over-expansion is accomplished because there is some snap-back tendency. Please discuss your concerns with your qualified pediatric dental specialist or qualified orthodontic specialist to check this for you.
