Thanks Jeanie for you reponse. I actually had a dentist appointment today for a cleaning but my hygienst canceled my appointment. I asked if the dentist had anything opened and he did, so I went to see him. He filed the broken tooth down even more. He feels that my tongue is irritated right where the broken tooth is. He could see the sore. He took pictures for me to take to my ENT. Told me to rinse with warm salt water three to four times a day. I see my ENT in a couple weeks and will have him look at it. I hope it heals and that this is what is causing my pain. But, I just can't help form thinking that my cancer is back. I keep telling myself its not cancer until they say it is cancer. Thanks again for your response. I hope things get better for you. I will be thinking about you.
