is it my teeth that give me problems or is it something else

I thought I answered this last week, but it must not have gone through. First, you sound like you need to be rinsing your mouth carefully with warm salt water several times a day to help with the infection. But it sounds also like possibly the infection is loose elsewhere. I would hightail it to a medical clinic and get some help. If you are running a fever you absolutely must seek medical care. For chewing ease, eat easy-to-chew recipes. You can find a cookbook full of them in One Pot Galley Gourmet. They are all easy-to-cook, easy-to-chew, one pot meals. How long has this been going on? You could have an impacted or abcessed tooth perhaps. Those can be excruciatingly painful and actually quite dangerous and serious.
