Not sure myself, a lot of unfixed and constant typos to me would indicate illiteracy. Usually, when a person reads well, they also spell well. The two go hand in hand in hand. I taught my daughter to read at the age of 3 and she quite naturally became the local spelling bee champ.

I'd be wary of any doctor or dentist with poor communication skills, if there are problems later you'll probably get the big shrug that naturally goes along with that.

A good doctor is meticulous not sloppy. And even if it were from mercury poisoning earned on the job, slack is not the way to go. If a doctor that treats AIDS patients acquires AIDS would you still want to visit him too? A dentist that acquires mercury poisoning on the job indicates a dentist that only thinks he knows what he is doing, but obviously is too dumb to treat himself (and probably others) properly. Not a good choice of advice in my opinion.

I visited this one dentist after already being mercury poisoned, just a regular dentist, for an opinion, this dentist has a very good reputation locally... and I say to him that I have mercury poisoning... this is when all my teeth still hurt... and the guy says to me incredulously..." I have a few amalgam fillings in my molars and they don't bother me" . I asked him if he wanted to see the the test results that were in my briefcase but he declined, I guess he didn't want to even begin to discuss it. So i go home and I am thinking about this... and I guess it's a good thing that the guy is not a heart specialist treating people who have had heart attacks... because you know, his heart is fine so far...

I did not go back there.
