To the Editor: Customer loyalty has little to no value when it’s billing time these days. With the same dental practice for 50 years I have seen dental costs go from affordable to going through the roof. As a senior, veteran, depending on my Social Security for income, I can no longer afford $400-$500 for two pinhole cavity fillings. When I was still working at 74, I once calculated that I would need to work 30-40 hours to pay for one dental procedure. Has the dental professional caught up with brain surgeons? Two weeks ago I wrote to my dental provider that it was necessary to forego my next appointment for two pinhole cavities for lack of funds. Did I in turn receive even an acknowledgement of this notice? No I did not.
