Response from The Pure Sleep CompanyNov 12, 2020

Some degree of soreness is normal during the first three or four full nights of use, as you become acclimated to using PureSleep. However if it didn't fit your mouth, there was probably a problem when you fitted it to your mouth and that could cause pain beyond the normal soreness. You may therefore address both problems by repeating the fitting process to make a deeper impression. If that doesn't work, try contacting our customer support department and they can swap your current PureSleep for a new one -- completely free -- so you can repeat the fitting process.
