Just curious. This week went to my 6 mthly hygienist visit and saw a different one to usual. Before she started she was measuring something to do with my gums and said *Last time you were a 2, this time it's a 1* and sounded quite pleased. I forgot to ask her afterwards - what's being scored and can I make it even better? Just curious really! My usual hygienist must take the masurement but never tells me about it!
