Retainers don't fit - do I wear them anyway? My bottom retainer won't fully snap on. I didn't wear my retainer (which I should wear every night) for a month and now it doesn't fit.

it was very painful but I've been forcing it for a week and it's not painful anymore but the bottom retainer is not fully on and no amount of pushing seems to work - should I keep using it even though it's not completely on or should I just not bother? The top retainer fits fine.

I think it may be my growing wisdom teeth pushing my bottom teeth out of place so I was going to keep wearing it at night even though it's uncomfortable.
