Can any one remove my fear
Hi, your gum bleeding isn't from leukemia. We can know that from a variety of reasons, including your history with the bleeding and also that platelets have to get much, much lower to cause bleeding.
I suggest not worrying about leukemia, but concentrating on conquering the gum problem instead. Good luck.
Well, probably the first cause to suspect for lowering platelets would be some infection, whether the gum infection or any other infection such as even a virus. Infection causes inflammation, and inflammation causes platelets to get 'sticky' and clump together, which uses them up.
Mental stress can be involved. "RESULTS: MPV was found to be significantly higher... and platelet count was found to be significantly lower in the [high anxiety] group"

Antibiotics of the type called 'sulfa' might result in platelet destruction. Then the body tries to make up the difference by rushing new platelets into production.
New platelets are bigger than old platelets, so that makes the MPV (average size) higher.

Bleeding from low platelets would possibly start to occur at 100 or even 50 or less. You'd also expect easy bruising in arms and legs, etc., at that point.
Yes, everyone makes new blood cells all the time. Whether your platelet count increases depends on if you are making more than you are losing. There is no way to predict what will happen at the moment.
