Hi have swelling on the lower left gum and it feels like a burning. I cant open jaw fully as its hurts. And also pain on left gum and throat when swollowing. Any ideas of what it is, im making an appointment for the doctor tomorrow.. my name is rory, my email is  YYYY@YYYY  thankyou!
Thanks for your query, the gum swelling is because of the gum infection which is caused by food debris. This can be treated by cleaning your teeth.but the limited mouth opening could be secondary to the gum infection around the wisdom tooth causing pus formation spreading into tissue spaces.confirm the diagnosis by taking radiograph of that tooth...take a course of antibiotics and do saline gargling.maintain oral hygiene... I hope my answer will help you.take care.
