Most likely this is simple PERICORONITIS
(inflammation of gum tissues surrounding erupting third molars).
this is a simple but painful condition in young age, seen in most of the patients with eruting third molars. the condition will subside within a few days after following these simple therapies. first maintain a good oral hygeine, especially brush on that side twice a day even if it hurts slightly, supplemented with CHLORHEXIDINE
mouthwash in warm water. or alternatively you can use warm SALINE rinse (mix a pinch of salt in warm water).
Also, you can use tablet of (Ofolaxacin+ ornidazole
) combinaion along with a pain killer (Diclofenac
Sodium+ PCM). both to be taken twice a day for atleast 3 days..
the swollen lymph nodes
are a part of this pericornitis, which will also subside in a day or two..
