Let me list things individually:
#7 - is the tooth number
D2332 - means a 3 surface tooth colored filling in a front tooth
Since you have two D2332 charges, there were two separate fillings on the tooth (this happens sometimes)
The fee - of $266 x 2 - is what the Dentist charged you
I realize , as you do, that Dentistry is expensive. Just a thought... It is very common for people to ask if there is a cash discount, or a senior's discount, or a good patient discount, or discount for "anything"! Very often, if you ask the Dentist, or ask the receptionist to ask the Dentist - he or she will give you a discount. In fact almost always. It is done quite frequently, and you'll not be out of the norm for asking. Heck, I've discounted about $20,000 annually for well over the past 20 years plus. I hope this may help you.
