I can't give you an opinion without seeing you but I will strongly suggest that you see a dentist asap. I am sorry for your childhood experiences and I can certainly understand your reticience to see a dentist but there are many excellent practitioners out there who are empathetic to your needs. You are only delaying what will be necessary with the chance of more work than is needed if you make regular visits.
A friend of mine used it when she had bleeding gums and it worked out quite well for her.
