Anyone whose ever been to a bad dentist would see the merit in this. I used to go to a &quot;budget&quot; dentist when I was a kid and had very painful experiences, it can be excruciatingly painful if the dentist doesn&#x27;t know what he&#x27;s doing.. or doesn&#x27;t care.<p>This is not a point that transfers 1:1 to a hair stylist.. the odds and consequence of a stylist cutting me vs a dentist tapping a nerve is.. huge.
