Wound in mouth infected. Be infected?

Because the level of infection in The Saliva can never be zero there is always a chance of secondary infection to a healing wound. Please follow the instructions given by a dentist meticulously so that the post operative healing phase is as comfortable as possible. There are some symptoms of localised infection which can be checked by you only---- localised elevation of temperature is the simplest test---- please check whether the cheek on the extraction side is warmer than the cheek on the opposite side and if it is so it is a sign of infection. Swelling and redness in the area will also indicate the same. But even if that is the case the appropriate antibiotics should not be taken as self medication and you should consult your dentist for the same. Regards
