### input:
Hello I have a swollen gum on my back molar next to my wisdom tooth on the bottom left hand side of my mouth. It isnt really painful and Ive been to the dentist recently where I had a full clean. Is it possible i have something stuck in my tooth. It was pusy but has stopped now. I have no swelling on my face and I have had a bad infection before so I realise it is no where as painful as that. Have you any idea what it could be? Laura
