What causes low WBC count after tooth extraction?
Patient: In Dec I had a tooth pulled, 2 1/2 weeks ago I had prep done for a bridge.  I have had a sore where the novicain was injected.  A week ago doctor called saying my blood test came back with: WBC at 2.9 (range 3.6-9.1) and lymphocytes at 46 (range 24-44).  Is there a possible connection?  Thank you. Doctor: Welcome to H.C.M. I am Dr Krishna Dubey.My dear firend , there are not any connection with tooth extraction.So no need to worry. It could be due to some viral infection because lymphocytes are also slightly raised.You should repeat your complete blood count with peripheral blood film.This will very helpful to rule out any further query.Thanx.
