When my lower wisdom tooth and surrounding gum was sore a few years ago I had swollen glands and a sore throat on the same side. I found ibuprofen worked best as it's an anti-inflammatory. Make sure you have something to eat before you take it though(even just a biscuit or piece of fruit)because taken on an empty stomach it can damage your stomach lining.
hey my daughter is 4 and has a tooth coming (where adults get there wisdom tooth) she also has a swollen gland on this side. I thouth the worse that she had cancer but had her at the ENT and he said he thinks it the tooth.
