<s>[INST] Hi, I m very concerned about my 6 years old son. I noticed him to spit out saliva more often or wipe it out with his shirt. A lot are also retained on his mouth when he speaks. He was not like this before. I just noticed it for 2 months now. Thank you so much. Worried Mom [/INST] Hi,From history it seems that he might be having some infection in oral cavity like ulcer in the mouth, decayed carious teeth or some tarter ed deposition on his teeth.Consult oral surgeon and get examined.Ask him to do antiseptic water gargles.Keep  local oral hygiene clean and healthy.Ok and take care. </s>
