Dr. Rosenstein used a special kind of sand paper to remove stains between the teeth. Dentists I have been to since then mistakenly refer to these stains as "decay" as if they believe the patient is too stupid to understand distinctions. Why do dentists "talk down" to patients? But the sandpaper approach is superior to drilling. He also took X-rays to check for bone loss. Sometimes I can stick a toothpick between my tooth and gum to check for bone loss. But last week I did not have a toothpick so I used a knitting needle and had to see an emergency doctor from the resulting infection. Sometimes I wish our differences of opinion re correct medication had not resulted in the termination of treatment, because he did get many things right.
