Hi,
I think its better to get it removed without a second thought as its causing discomfort and which will later lead to inflammation of particular area and can further cause malocclusion, disfigurement of adjusent tooth structure, caries and many other trouble to other teeth in oral cavity.
Next Steps
Antibiotics and pain killer after extraction and from the next day you can start gargles with normal saline or lukewarm water to subside the inflammation.
Health Tips
Maintenance oral hygiene by brushing twice daily, do flossing, mouth rinsing with mouthwash.
