How would the dentist know you have sleep apnea unless you fell asleep in the dentist chair?! As the above says go for a sleep study and they can find out what you have. I went for a sleep study and found out I have sleep apnea and restless leg syndrome so consequently my sleep is interrupted a lot. I cannot or do want to wear a mask at night. Too uncomfortable.

For reduction of sleep apnea and lessening risk of a heart attack then reducing weight can help.

Also you are supposed to drink water during the night even though you have to go to the bathroom more frequently. This can reduce the chance of a heart attack apparently. I am not a med professional.
