Can I take Doxycycline Hyclate 100mg for an abscessed tooth?

                        I have an abscessed tooth and my right cheek is swollen. I have no insurance and no money to pay for an ER visit. I am about to be evicted from my rent. I have a full prescription of Doxycycline Hyclate 100mg. Can I take them to treat the abscess? If so what is the recommended dosage and for how long? I have been battling this problem on and off for a year now and cannot afford another ER trip at $600 plus prescriptions. In the past I have been prescribed Penicillin.
