Saliva appears reddish/purplesish/reddish brown in the morning. Or mostly anytime I get up from sleeping even in daytime. Some days darker, some days light. Never a taste of blood and always translucent. No pain. Tops of some teeth have been sensitive. I used a toothpaste for sensitive teeth and that feeling is mostly gone now--on some teeth totally gone. Gums seem firm and of normal colour. Had a physical recently and no calls from doctor about blood tests etc--though I have yet to get the results. I feel fine and am athletic. Biggest issue is lack of sleep. Averaging 3-4 per night.
