We have designed our products so they can be fitted without a dentist. However, if you are happy to spend the money, there is no reason why you should not involve a dentist. Your dentist could take your impression for you, or could simply give their opinion about whether or not your teeth are suitable for mandibular advancement. Your dentist could tell you if there are any obvious reasons why you should not wear a mandibular advancement splint. It is worth noting that many of our customers successfully fit a standard SleepPro, and take a SleepPro custom impression without any input from their dentist. However, if you have a non-standard bite or irregular teeth, then it may be best to get your dentist involved.
