Dentist says gum and teeth strong. Have some gum desease. However the overbite is now very pronounced. There is a nerve reaction of teeth pulling back when attempting to put front teeth together as of this week. Can now feel back top teeth on tongue and movement of jaw when lie down. Dentist stating clean teeth is not helpful as teeth are generally clean and have not experienced such fast teeth movement before. Which type of specialist can help with this? Periodontist, ear nose and throat etc? Any advice welcome.
