It is normal to drool all the time after tooth extraction, you can swallow the saliva and the condition will gradually improve without special treatment. After tooth extraction, due to pain, do not dare to swallow saliva, so saliva will always gather in the mouth, so that the patient has a kind of salivation (drooling) feeling. This is normal and is considered to be an increase in reflex salivation caused by a combination of pain, nerve damage and psychological effects. With the above condition just swallow the saliva and do not brush and gargle on the same day to prevent increased bleeding due to dislodging of blood clots caused by gargling. Try not to spit the saliva out, as the act of spitting also reflexively increases salivation. After tooth extraction, it is recommended to pay attention to oral hygiene to avoid food debris falling and retaining leading to infection and other situations. If any abnormal redness, swelling or fever occurs during the recovery period, you should consult a doctor promptly.
