Hi, charmedwitch!
I'm sorry your tooth is bothering you... does it need to come out? Possibly, but I think a dentist appointment should be your first order of business.
It could be that the wisdom tooth is impacted and causing you pain, or it could be that you have an abcess or infection in the gum around/under the tooth. If the gums are loose enough, there's also a possibility that maybe something (food or debris) has gotten lodged down there and it's causing it to swell and be painful. A dentist will be able to tell you, for sure, and hopefully give you something for pain (or remove the object for you/prescribe something for the infection, too, if that's what it is).
In the meantime, you can try topical ointments like Oralgel to help relieve some of the pain (dabbing it on with a Q-tip works the best for me, personally) and also over-the-counter meds like Ibuprofen, which will help with swelling (and hopefully also help relieve some of the pain); luckily, you can use both at the same time if you want!
Good luck; I hope you're feeling better!
