I was thinking about it again today and I have changed my diet somewhat. I'm trying to lose some weight and added vinegar to my regular salad dressing to dillute it. Also, I brush my teeth an extra time with my husband's "whitening" toothpaste in the morning if I have a cup of coffee.

I get my teeth cleaned twice a year and I had it done last week. They tell my my gums are excellent and I floss each night so no extra gunk on the teeth.

I hope it's only that and not a consequence of the Tysabri. Thanks for your response, you're a real asset to the forum.
