Some bad tooth advice: try to floss with a water pick if you can, do it softly, after you brush your teeth. Follow by rinsing with 1 part hydrogen peroxide and 9 parts warm water—DO NOT swallow the hydrogen peroxide mixture, and definitely please make sure to dilute adequately with water. Are you in any state that has Medicaid? I think I remember it having a dental component. In lieu of that, a lot of dental schools offer free services. Good luck!!
