Yesterday I was told by my dentist that I have bone loss in I use peroxide mouthwash, floss, whitner, scrape my whole teeth with a pic thing to keep the stains of because of drinking and tea and smoking, use listerine. I'm really upset... I have problems with my back, fibro and chronic fatique, osteoarthritis, etc. I asked the dentist how this could happen and he mentioned steriods. I have been getting blocks for 3 - 4 years on my back, 3 to 4 a year. It is my understanding these have steriods in them. I am very sensitive to medications, and at one time took steriods and my throat almost closed up, so my pain mgt Dr. is very careful giving me steriods. Is it possible it is the steriods that caused this?
