@Jenlyn62  Admittedly that type of wear and tear is likely to happen over time.  Unfortunately, it is a thin line between a snug enough fit to keep the bottle secure (in various riding conditions) and potentially too much pressure being applied as you describe.

If you would like to compare a different style that might be a little less snug, I would recommend this REI Junction cage or one of the Planet Bike cages.

Hope this helps!
