Dentist question. Options

[Tung]

I have a question about dentist bill and my insurance policy.

Lets say i go to the dentist to get a filling, and the total is $1000. They say my insurance will pay for it, so they gave me a filling. NOW, my question is this.

If i quit my job that pay for my filling after i got my filling, will my job benefits pay for my filling? I was told that if i go to the dentist and they say i have a balance of $1000 from my job. So i go ahead and have a filling which costs $1000. After my filling, i decide to quit the job. Will my job pay for the filling or will i have to pay for it since i quit? Considering dentists and hospitals take only a certain amount of money from my health benefits and not the $1000 at once. Do you guys know what i mean?

Here's another example.

I've been told that sometimes, hospitals and dentists take some money out of that $1000 from my insurance and not just take $1000 at once. You guys know what i mean? Do they take that $1000 out at one time or do they take some each month or something? Or what if i decide to quit after i get my filling. Will my health benefits cover for my filling or will they make me pay? Remember, my dentist gave me a filling while i was under the health benefits, but after the dentist gave me my filling, i decide to quit a week later. So will my health benefits make me pay for the filling or will they?
