solicemoon.....This is not something I can justify "sugar-coating"... no pun intended. I will be blunt, since I believe this is necessary. The "mouth," by it's very nature, is a perpetually open, moist, warm environment, as well as the main ENTRANCE to the body. Tooth pain, 96% of the time, indicates "INFECTION."
You need to know that the toxin created by these infections, fester and become worse with time, while in this oral environment......and obviously seep into the rest of our inside, spreading poison, throughout. It is not uncommon, that people have Dental become "septic"....and many have died from secondary infection and other issues.
If your area has colleges and/or Universities, with Medical/Dental Depts, call them to inquire as to their Dental Student programs. Final year students, while being carefully supervised Molars by experienced Dentists, accept patients and do not charge Teeth for this. Also, most communities have free health clinics.
Whatever you have to do.....do it. Please do not How Often Should I floss? ignore this or attempt to "fix" yourself.
Write something about yourself. No need to be fancy, just an overview.
