It seems safe enough to simply state that your front teeth are exposed to a greater level of force than they can withstand.

For whatever reason related to the physics involved, some of the forces get focused in a region of some of your crowns (hence they chip), others are absorbed by some crowns as a unit (hence they come off), and then some forces get directed to your teeth and their crowns as a unit (with the root evidently being the weakest link for at least one tooth, hence it has broken).

It's our back teeth that are supposed to bear the highest level of forces. People who don't have back teeth (your previous situation) subsequently shift their chewing activities forward. And as a result they often have problems like you describe because front teeth aren't intended to receive that level of force (constantly and regularly).

Possibly your replacement teeth in back aren't fully functional? (Possibly they don't come into full contact when you close together, hence you still chew with your front teeth? Or possibly the habit of chewing with your front teeth simply still exists?)

Or due to previous tooth shifting and wear (as a result of the loss of your back teeth), when your dentist rebuilt your mouth they "opened" your bite (made the height of your teeth closer to what they were originally) but by an amount that was too great, hence persistent forces are created (and evidently focused on your front teeth)?

Or possibly the excessive forces that exist are due to a habit of tooth clenching and grinding? (A very common scenario.)

For a start, evaluate what your current situation is. Your jaws have a normal "rest" position (teeth fully apart by a fraction of an inch) that they should be in almost all of the time (except when you are eating or at the end of a swallow).

If yours aren't, that's probably where the excessive forces that affect your front teeth come from. (This would be a common scenario with people who clench and grind their teeth.)

If you are at rest position 99% of the time, then the question is why when you eat is such a high level of force directed too your front teeth?

With the first case, you need to quit clenching, or else wear an appliance that can help distribute the forces your habit creates.

With the second case, unless it is the situation where an old habit of chewing with your front teeth simply persists (and can be corrected), your dentist will have to figure things out.
