I’m about to give up hope here; is there any dentist that will fill in a cracked wisdom tooth?

I live in USA and my options for dental care are extremely limited. I have drove hours at a time to get dental help off and on my whole life, but I developed a chip/crack in my wisdom tooth over the New Year and managed to have a dentist look at it who was about an hour away from where I live.

I’m not in any pain from the chip, but I don’t want it to get any worse. This specific dentist office refused to do anything to fill in the chip, but were insistent I have all four of my wisdom teeth removed asap, and were overall unhelpful.

Besides money problems, I have health issues that make having any kind of major surgery dangerous, so I’d also have to find someone who could operate with those health issues in mind.

Is it true that despite having your wisdom teeth grow in fine, a dentist won’t fill one in? I just want the truth. I am so tired of being told contradicting answers by these dentists.
