Thank you for the query.
Wisdom tooth usually when erupting develops pericornitis i.e.infection caused due to the foodlodgement in and around the flap and getting inflammed leading to formation of abscess . This is what has happened in you case as well, the yellow spot is the abscess . I suggest you to get an x- ray done and visit your dentist for the treatment. Operculectomy is the procedure to be performed in this case where the flap leading to food lodgment and infection will be removed exposing the teeth.This should be followed by a course of antibiotics and analgesics .If teeth is impacted and decayed then it has to be removed surgically.
Hope this information helps you.

Hello and welcome to HCM,
Wisdom tooth is the last tooth to erupt in the oral cavity and the loose flap over the tooth is the area often subjected to infection due to food lodgement and improper cleaning. Inflammation and bacterial infection leads to formation of abscess in the flap,this condition is called pericoronitis. the yellow spot is nothing but the abscess draining point. i suggest you to visit a dentist and get a x ray done which will show if the tooth is infected and the position of the tooth. accordingly abscess drainage is done with Operculectomy that is the inflammed flap is removed surgically. If the tooth seems to be impacted in jaw bone then extraction is done followed by a course of antibiotics and analgesics. thanks and take care

hello & welcome
this is known as pericoronitis.
as your wisdom tooth is partially impacted, gingival flap covering this is known as pericoronal flap, and swelling of this is known as pericoronitis.
if this become chronic than you have to visit your dentist for removal of this tooth.
in the mean time along with warm saline rinses you can start up with betadine rinses, and ibuprofen (SOS).
thanks & take care

since there is still flap covering the wisdom tooth,it has to be incised and removed by operculectomy.

betadine rinse and warm saline gargle can be done occasionally.
take complete course of antibiotics-analgesics prescribed by your dentist.

rinse your mouth after every meals.
brush your teeth twice regularly.
