Dear Dr. Wallace:

I was told by my orthodontist shortly after I got my braces off that I apparently tend to grind my teeth at night. I was told to get a night guard or Invisalign type of product. Both of these options are expensive, and I know this because my mom bought me a night guard, but I lost it at a slumber party in the county next to ours.

Write to Dr. Wallace at rwallace@galesburg.net.
