I can't sleep because of my brother's snoring. what should i do?

If possible..: Have him see a physician to rule out sleep apnea which can be life threatening. The physician can also offer suggestions if there is only snoring.

Physician first: If the physician rules out sleep apnea or other medical issues, then the dentist can construct an easy to wear specialized mouth guard that helps to reduce snoring or mild sleep apnea. For people who are overweight, loss of excess weight may provide improvement.
