I will add my 2 cents for what they're worth. Not much, I can assure you.
My 3 siblings and I all have/had bad teeth. We are older than Jack Bristow and 20/20, but were raised on a farm and we didn't have city water. No fluoride, but our dentist was always giving us "fluoride" treatments in the office. I don't think it helped much and wonder how much it cost my parents!
I began my dry eye odyessy almost 10 years ago after Lasik surgery. Two years ago, I was diagnosed with Sjogrens. Duh, duh, duh. All those ophthalmologists I traveled to see in other states, highly profiles docs, not one of those suckers or even my own Lasik fellow ever suggested Sjogrens. My rheumy guessed the start of my Sjogrens was about the time of my Lasik. (No connection intended on her part.) I have much more than dry eyes and mouth, many neurological things going on. It was me who led the docs to this diagnosis.
Is this the reason I've always had bad teeth? Most are now caps and crowns and have been for many years. No sibling reports autoimmune symptoms. My daughter has good teeth, but does have autoimmune as in Type I diabetes and Graves disease.
Jack Bristow, I hope you do what you feel is the right thing for you. I also hope it's not enormously expensive. But, you're quite young and if you think this is your cause, or even partly, it might be worth the investment. Nix to bad teeth, dry eye, autoimmune problems, bad doctors, etc. etc.
Don't trust any refractive surgeon with YOUR eyes.
