More likely to be stuff coming out of the extraction sites while they are still healing,,, when you eat it puts pressure on these areas and little bits of fluid come out, try some things that are a little more acidic like soft bread and butter with blackcurrant jam but warm it and strain the pips out first, orange segments and crushed pineapple the bromelein will help soothe any soreness, they will stimulate saliva production and help clearing debris too. once your mouth is fully healed you should be fine again
