I have my full sympathies with you on your condition. However you have to visit an dentist asap and you will surely need antibiotics first to start with treament so as to take care of your infection and pain. if it is an emergency then you can go to ER who will examine and give you immediate treatment. For the timebeing you can take pain killer tabs and do warm saline rinses 2-3 times a day. The other place for you could be trying a dental school who are specialist in these kinds of treatment and are definately cheaper than privat dentists. For finding affordable dentist or free dental treatment you have to google hard. for finding these kinds of treatment you can read this link which can be helpful to you...http://www.identalhub.com/article_free-dental-treatment-493.aspx
