my gums are bleeding too much. whenever i spit blood comes from my gums. i am facing this problem from last 3 years. before this, i didn't had any dental problem. i had consult to a dentist and done an OPG Test. but after that he told me no problem detected in test. so now i am very upset. is this pyorrhea?. is any permanent treatment available for pyorrhea?. what to do now? please suggest me.
