The worst are the ones who have just had a smelly lunch, a fag or coffee. Yuck.
I tell them to use mouthwash. I always have bottles of water and a couple of glasses in the room and a bowl of mints.
It is amazing how much difference just having a drink of water can make to a clients breath, I'd say about 75% of the dodgy breath people are 'cured' once they have had some water.
And I must admit that I just tell them that their breath needs a little freshening up. But obviously if their dental hygiene leaves a lot to be desired I will not kiss them or let them give me oral.
I did once have a client who only had a stump of his lower front tooth left in his mouth. He was shocked when I wouldn't kiss him! He wasn't that old either. He said he hated dentists, and I said so did I and that was why I wasn't going to let him put his mouth anywhere near me. I still shudder when I think about him.
