If the wisdom tooth is inclined and the gum over it is swollen, it is most likely that the tooth is impacted (stuck, and not likely to come out fully). It would be advisable to get an X-ray done, and see if it needs removal. As for relief, you could rinse with warm salt water.
Next Steps
Visit a dentist for X-ray and if removal is needed get it done from an Oral surgeon.
Health Tips
Watch for swelling and severe pain. It is usually a sign of an infection.
