Hi all, thank you for your suggestions. I will look it up and yes I catch my cheeks quite often! My mum also has a clicky jaw and her dentist was horrified when he dislocated it unintentionally when carrying out some routine dental work!! My jaw doesnt click but seems quite mobile so I will make an appointment. I have ground my teeth constantly for years and had a guard but it just made me gag!! Not an option now thanks to some false teeth!!
