My gums have been bleeding after brushing and flossing for about 6 months, and its getting worse. I take excellent care of my teeth, and my dentist tells me after a recent visit that I have no signs of gingivitis or dental disease. I have minimal tartar, and I see a dentist regularly. At his request, I had a number of blood tests, all of which came back completely normal (CBC, INR, AST, White Blood Cell Differential). What Next? Are there other blood tests I should consider? If i have "beautiful, almost perfect teeth" (my dentist's words), is there any use in seeing a periodontist or oral pathologist? All dental costs are out of pocket for me, so I want to avoid unnecessary exams. I am a 47 year old male, in excellent physical health with regular exercise (cardio at least 40 minutes 3x a week), on no medications, have no underlying medical conditions of which I am aware, have no bruising or rashes or fatigue, have a healthy diet and take supplemental multivitamins several times a week. Still, I'm spitting mouthfuls of blood every time I brush.
