Bristles...

...on brushes for Tiny Tuesday "B" things today...

Roy has recently had a crown on a back tooth, and he was advised to use the orange inter-dental brushes at 0.45mm round it, rather than floss. He's discovered he needs the next size up ( red - 0.5mm ) for the gaps between some of his other teeth. The night-time beauty routine gets longer as we get older... ;)
