Q. My mother is 72. She takes approx 2mg of Warfarin daily as she has a mechanical aortic valve. Her INR is extremelly erratic and she has to have blood tests twice weekly as INR can vary from 2 to 4 within a week. She has lost 2 teeth which are within the visible smile (and 2 others to the side of her mouth). She has just had a plastic bridge constructed and is totally dissatisfied with it. It is enormous and is shaped to the roof of her mouth (has 4 attached dentures). She cannot eat or sleep with it and feels sick as she has a constant gagging feeling. She only really needs the 2 teeth replaced. Is there another option? A metal bridge? Teeth rooted into the gum mechanically? Dental implants? Clearly she is not a straight forward case due to the INR fluctuation but any advice or alternative to the current situation would be greatly appreciated. I live in London and she can stay with me for any procedures. Many thanks
