hello and welcome to HCM forum,
i would be glad to answer your query,
In your case, the gum which is covering the wisdom tooth partially is slightly inflamed, this condition is called 'pericoronitis', it is nothing to worry about.
sometimes, food gets impacted in the gum tissue which forms a pocket around the tooth nd causes pain and swelling.
kindly perform warm saline rinses(3-4 times/day) ,it will relief pain and swelling.
It is important for you to see a dentist, he/she might prescribe medicines to resolve infection if present.
i hope i answered your query,
i wish you good health,
take care.

Hello,
In case of partially erupted wisdom tooth, flap of gum tissue is created where food impaction can occur. This condition is known as Pericoronitis and in this condition, gum tissue will appear swollen and gum tissue will appear red. Pus discharge may occur from the gums. There is difficulty in swallowing; closing the jaws and bad taste and odor is present from oral cavity. For treatment of Pericoronitis, debridement of area or operculectomy that is surgical removal of flap over partially erupted wisdom tooth can be done and if the condition recurs, then extraction of wisdom tooth may also be required. You can visit your dentist for evaluation and treatment. By the time, you visit your dentist, you can do warm saline rinses 3-4 times a day to reduce the swelling of gums and keep wisdom tooth area clean. Food accumulates in relation to wisdom tooth will aggravate the pain.

hi there
thanx for the query
yes absolutely u need to visit a dentist
you will require a small surgical procedure named OPERCULECTOMY which is cutting of that small flesh on top of your teeth under anaesthesia.
get a xray of that tooth so that if your wisdom tooth is impacted it can be extracted. which will lead to no other complications in future.
at home you can start with MOUTH WASH RINSING. take pain killer if required
do visit a dentist for x ray and further treatment.
thanx
regards

Hello there....Flesh that covers your wisdom tooth is called the pericoronal flap....any inflammation to the flap would result in Pericoronitis... As and when you occlude this flap comes between your upper and lower tooth and owing to the repeated friction it enlarges in size...that leads to small pocket between the flap and the tooth underneath, resulting in accumulation of food beneath the flap...this would result in abscess if left untreated....Pain your experiencing is because of the inflammation...
There are two ways of handling it- Operculectomy- procedure done under local anesthesia, where the flap around the tooth is excised and the tooth is retained...But there are all chances for the flap to regrow resulting in the same symptoms you are experiencing now... This is now out dated...for a permanent solution get your wisdom tooth removed...Consult a Oral and Maxillofacial surgeon for the procedure...
