First try to keep the area clean. Rinse your mouth 5-6 times with warm salt water. Do an OPG and then visit Oral and Maxillofacial surgeon.

Go for opg xray. If tooth is impacted then go ahead with extraction

Hello First of all you need to keep that area clean otherwise the gums in that area might become infected (pericoronitis) so rinse your mouth with lukewarm salted water after every meal Next you need to get one OPG done and then visit your nearest Oral and Maxillofacial Surgeon to get an idea about whether your wisdom tooth is in a favourable position to erupt or whether it is in an abnormal position in case of which you need to get it removed.

Kindly do not postpone treatment. Visit dentist for clinical examination and x ray. Treatment depends upon deacy, angle of tooth and space available in jaw. Meanwhile you can go through the blog in the link below.
