Below are views of a compromised airway and one with an oral appliance solution in place.
“Boil and bite” appliances purchased in a store or on the internet may help a small number of people for a short time. They may be useful as an interim appliance temporarily when a custom appliance needs to be sent to the laboratory for adjustment or repair. They tend to not stay in the mouth very well and are not made as strong as custom appliances. They can also cause problems with chewing and pain in muscles and joints.
In a research study, over the counter appliances have been shown to be less comfortable and less effective than custom appliances. If they don’t work well a person may feel discouraged and believe that all oral appliances are no good. This would be a disservice to people who are really suffering and really may need this valuable treatment option.
