I was about the same age when my troubles started. I knocked a front upper tooth out at work on nights.
at 3 am no choice but to put it back in best I could.
Stayed loose for about 6 months till I made a visit.
Over the next couple of years I had canals , 4 teeth out , a partial plate, fillings etc, every time I went he found more bollix.
I had had enough.
I fecked him off.
Last 4 years I just clean and floss and have had no issues.
I'm sure most Dentists used to be M.O.T testers.
Always finding something .
