Hello and welcome to HCM,
Wisdom teeth usually erupt in the age group of 18 to 25 years or sometimes in the later part of life. you present the symptoms of swelling and pain in the gums which are the signs of infection and abscess
Wisdom teeth are often impacted in the bone and do no find enough space in the oral cavity to accomodate and the area is prone to infection due to food accumulation and improper cleaning which results in formation of abscess.
i suggest you to visit a dentist
and get a OPG radiograph done which will show the exact position of the tooth in relation to jaw,adjacent teeth and other vital structures. Accordingly surgically removal of the tooth can be planned.
Mean time you can start with antibiotic Augmentin
625mg with NSAIDs two times daily which will subside the swelling and pain.
