My left wisdom tooth has begun to come through, and although it s straight, at the moment it has only half come through, and the gum that is still covering it has been sore, along with the left side of the very back of my mouth , I realised the other day that there was pale yellowy puss coming out of the gum when I squeezed it, and now the flap is becoming loose, and when is wobbles a small section of gum around the back and side of the molar infront moves too, what should I do? and is this normal?
Hello, the problem u had described is called peritonitis. It means the swollen and painful gums due to erupting tooth. This problem can be prevented by proper cleaning of region and use of mouthwashes. If the problem is recurrent in nature then a radiograph is taken to find out the position of erupting tooth and its eruption angle.  Later on as per radiographic findings the treatment is carried out. Either extraction of erupting wisdom tooth or simple operculectomy to expose the erupting tooth. Sometime cheek bite is caused by upper and lower wisdom tooth due to wrong angulation of their cusps at that time both upper and lower teeth needs to be removed.if pus formation is there u need to take antibiotics and analgesics to treat infection immediately.
