Failing composite filling

I am in my 20s and had a compositing filling done on the side of my central incisor but it cracked after 4 years. Already replaced once but it would only be a matter of time before this one also fails.

The second dentist said there is a chance I need to get root canal if the new filling fails again. I feel so duped by my first dentist. It shouldn't have been drilled and filled in the first place.

1.Is there any permanent solution to this? Remove the filling altogether and hope for the saliva to redeposit enough minerals?
2.Everytime the fillings gets replaced, the dentist drilled deeper and deeper into dentin and removed more natural teeth structure. Is there anyway around this?
3.There is some report that says scientists are trying to use calcium ion solution to regrow dentin naturally? When do you guys think that new technology will happen?

How can you be sure it shouldn't have been restored in the first place? Is the filling failing because of recurrent caries or because it is simply falling out due to improper retention?

This question is bordering on asking for medical/dental advice, which is not permitted on these forums, but I can tell you what they teach us at my school.

There is no way that you will be able to fully remineralize the tooth if you remove the restoration. Once enamel is removed for a prep it doesn't "grow back".

if a composite restoration breaks or fails after 4 years, that's not abnormal. If you have to replace a restoration, odds are pretty good that your tooth will have to be prepped more, which means more tissue removal. Once the prep reaches the pulp cavity, the necessity of a root canal goes way up.

Dentists currently use Dycal or something similar to promote dentin mineralization, but results vary.

In no way should any of this be interpreted as medical or dental advice.

This question doesn't just border on asking for medical advice, it does. As Lemon says, we can't answer that part of your questions. I will say this:

1. There is no such thing as a 100% guaranteed permanent solution to this situation. Similar to that there is almost never a 100% guaranteed solution to any medical "cure." Anything you do will still have a chance of failing at some point in the future.

2. There is no current timetable to the release of any products that will regrow dentin to the amount you are talking about.
