What is the life of the appliance?
A. This largely depends upon you. You should take care of the appliance as outlined in the instructions. If you are a tooth grinder (bruxer), the appliance will wear out more quickly. The worst case is about 4 months, and this would be very unusual. They can also last 18 months. So on average, your appliance will last 9 12 months. Still, this is only pennies per night, resulting in healthy, restful sleep for the whole household.
