Hi, what you have is called pericornitis. Pericoronitis is an inflammation of the gum tissue usually on the back portion of the gums around a tooth. It can be either chronic or acute. Acute pericoronitis can have swelling, fever and pain which indicates an infection that is not under control. Pericoronitis is not generalized gum disease (like periodontitis) because it is only found around one specific tooth. It is caused by debris that has not been removed and now is infected due to bacteria arising from the breakdown products in the space (sulcus) around the tooth.
You need to use warm salt water rinses: you can dissolve ½-teaspoon of salt in 8 ounces of water as hot as can be safely tolerated, and rinse vigorously for about 2 minutes at least every 2-3 hours. Please do NOT put any heat on the outside of your face and elevate your head when sleeping.
If this continues you will need to get an RX for an antibiotic.
