but happens very frequently. There isn’t a device in the world that positions the jaw forward that doesn’t put pressure on your teeth to move in that direction unless it is bone anchored, and those are basically never used. Some people’s teeth are resistant to the movement or get enough drift back during the day, or they already have plenty of space between their front teeth, so it doesn’t cause a big enough problem, but oftentimes it does. I get several of these cases referred to me every year.

That doesn’t mean the device shouldn’t be used. It definitely accomplishes its intended purpose but we should be aware of the side effects to decide if it’s worth it. If he can’t tolerate a CPAP for example it could be a worthwhile trade off.
