Q. I have recently recieved dentures to fill the gaps in missing teeth but these are causing problems. They are uncomfortable to the point of painful and impair my speech. Although I have most of my front teeth left it is hard to chew food properly. As I have colitus it puts my digestive system under more pressure to digest the semi-chewed food. Because I am unemployed I am wondering if it is possible to implants done on the nhs. I would be greatful for your reply.,
