I have been on warfarin for the last 3 months and I have 3 more months to go. About 2 months ago I started tasting the medicine and complained to the RN. She couldn't figure out why that was happening. For the last 6 weeks, I have been getting a yellow film on my teeth, my gums are beet red. I have been brushing 2 x's a day, flossing, rinsing with hyrdogen peroxide and Listerine. About an hour after I have brushed my teeth, the taste is back and the film is there. Many years ago I was diagnosed with receding gums and had a couple of loose teeth that were extracted. Due to being on unemployment, I have not been able to get to a dentist in about 6 years. My gums don't bleed when I brush or floss but they do burn for a bit when I rinse with the solutions I mentioned above. I also have a chronic gurd problem that was diagnosed 12 years ago and I take Omeprazole once a day for that. I know that acid can be deadly to the teeth. Could this be an adverse reaction to warfarin? I already have diahreah (sp?) due to the warfarin. This occurs any where from 3 - 5 times a day and definately 20 - 30 minutes after I eat. I had surgery on my knee in August and ended up with 2 to 3 blood clots in my leg. They say I have to stay on warfarin for 6 months. Can I do anything else to improve this reaction.
