I briefly read over your other posts, and it sounds like you are afraid of what the dentist will think, and that they are going to tell you that you need a bunch of expensive work done. I understand your fears.
First of all, though, as many of the others have already said, the dentist will not judge you. They will be happy that you came in, and that they can help you. People who get regular cleanings and routine x rays still have major issues. If you have read any of my posts, I have gone to the dentist every 6 months for cleanings, and still have had multiple infections, including a huge abscess on my front tooth.
Depending on the size of the break in your front tooth, a crown may be an easy fix. I broke my front tooth as a child, and they just did a filling. It abscessed this past year, and now I am getting a crown. About half the tooth was broken at the time.
I just saw that you have an appointment! Yay!
As far as money, my husband put it best. We can't afford it, but we can't NOT afford it. Your teeth can affect your health and quality of life. We are in a lot of debt right now, due to my dental procedures, but we know that it has to be done or the cost will be greater later. There are options where you can do payment plans, or sliding fees, depending on where you live, like Care Credit.
