Why have my dental crowns sunk in? (photos)

your smile is not even, and you will need to change the crowns, and abutments, provably is good time for you to have a more nice and even smile, with veneers not he side teeth, and crowns over those implants,the effect of crowns sunk, will be corrected.

Despite a CHRONOLOGICAL age, some people aren't done growing until later in life.  Women usually are done around age 21, men aged 25.  SOME people are done earlier, but to KNOW for sure then certain tests must be done.  Without knowing what it looked like in the past (for comparison) it is hard to comment.The photo does NOT make me think that this is the case.  The gumline is how we normally judge any eruption, etc. If the tips of the crowns (the incisal edges) are shorter, then it is possible the material is not as durable as other materials, and would need to be remade to correct it.  It may also be an indication of a grinding movement, but that normally affects more teeth than what appears in the photo.
