Difficulty in completely opening the mouth is called trismus
. this problem can occur after wisdom tooth extraction
, as it is usually a surgical extraction resulting in trauma to the adjoining tissues. If you have completed the course of antibiotics and your dentist
is sure that the extraction site looks clean then you just need to do warm saine gargles 3-4 times/day and may be a mild muscle relaxant
coupled with a pain killer to relax the strained muscles and help in healing. The pain should reduce and then you should be able to open your mouth fully without any difficulty soon. If the problem continues i strongly advice you to re visit your dentist for a thorough check up.
