Ive been waking up with about a teaspoon of blood in my mouth. It seems to come from the back of throat or wisdom teeth area.  Whatever it is it drains from somewhere at night. My mouth looks good in side but I am concerned.  Why does it drain only while I sleep?
Thanks for your query, I have gone through your query. The bleeding in the oral cavity could be because of the gum infection around wisdom tooth, or any cuts in the oral cavity or pulp polyp or any bleeding disorders like idiopathic thrombocytopenic purpura. Consult an oral physician and get these things ruled out. Get a complete blood investigation along with INR to rule out the bleeding disorders. If any gum infection then get your teeth cleaned and use topical gum astringents like stolen gum paint. If pulp polyp is there then get it root canal treated. If bleeding disorder is there then consult a general physician. I hope my answer will help you, take care.
