I have had several crowns in for 7 years, and am in the process of having 3 implants where I had a bridge.

I am always having to use inter-dental brushes and floss, but don’t seem to be able to get all the debris out from between my teeth. My gums are healthy but have started to shrink away from my crowns a little. Would it be safe to use one of the recommended oral irrigation systems, or would it make my gums recede more?
