Q. i have had gum disease for 15 years and had extensive treatments at bristol dental hospital.i have been trouble free for years now but have lost a significant amount of gum tissue.i was scared to smile for years. at the end of my treatment they made me a cosmetic gum shield that fits in my mouth and hides my gum loss.it works quite well and gave me back some confidence but i am always aware it is noticeable. can anything be done to for me?my teeth are ok but need whitening. i would love to have a proper smile again.can you help? no site ever mentions any help for gum loss.,
