Has anyone ever done or worked with myofunctional therapy? I have been for about a year. I think it has helped with nasal breathing. I wanted to try alternatives to the CPAP because I was diagnosed with sleep apnea last year. I also have high blood pressure and I’m a former smoker but I don’t drink. I noticed some red spots and it looks like some irrational near my back teeth. I showed it to the dentist and it thinks it may be because of a crown. Could red spots be a sign of irrational from the myofunctional brace?
