Hello and thank you for your question.
The only thing you can do is extract the tooth. If this has been bothering you for 6 months, you should have been putting money to the side to help cover the cost of the extraction. Taking antibiotics long term is only placing a bandade on it and not treating the problem. This can cause the bacteria to become immune to the antibiotics and become more dangerous. The lumps
are either abscesses
, inflamed lymph
nodes or the combination of the two. Google free dental
clinics near your area, if you have to travel 50 miles, it would be worth it if you cannot afford the treatment. This can be deadly and should not be left to linger.
I speak these words out of concern for your health and hope that you get this taken care of soon.
Best wishes and good health
