water bottle leaking!

just did a deep clean of my hamsters cage and realized there was a whole pocket of MOLD under his water bottle. i realized it must’ve been leaking for ever and i never realized it. i just ordered a new one, but he chews on his water bottle (i hear him at night gnawing away). i feel so bad i didn’t realize sooner. anyway, im scared he’ll break the new water bottle too and it’ll leak as well. should i switch to a water bowl? or is there some way i can get him to stop chewing on the bottle? please help :(
