Leo is always at pains to help you to relax. Recently I had a filling and the anaesthetic, which usually takes ages to disappear and you usually bite the inside of your mouth and feel like you've had a stroke, is now completely different. Only your tooth is numbed, not the soft tissue around it, and it is brilliant. There is no discomfort and your mouth is back to normal as soon as the procedure is completed. It is absolutely magic. I will never again dread a filling as I used to.
