Just some advice really, please. Since having my ceramic braces fitted about a year ago I always get a pressure sore from the main archwire on the top right hand side of my mouth. Where my lip sits on the wire it tends to cut in and dig, no matter how much wax I put on it. I play on a Denis Wick heritage mouthpiece and pre-braces I never got the pressure mark/ring on my mouth. I do get that now, which is fine as it doesn't cause any major problems, but what I am noticing is now is, as time goes, my embouchure is sliding across my face!! Pre-brace my mouthpiece sat just slightly to the right of centre, but now my entire embouchure seems to have slid to the right-hand side of my mouth. I think this is a sub-conscious thing that means that the hole in the m/p is now over the area that causes pain so there is less pressure from the rim. Anyway, having a discussion with a couple of other people, they have said that it doesn't matter too much if the embouchure isn't perfectly centered, as long as it doesn't slide up or down on the lip. So..... do I try and correct this, or just keep playing off to one side for another year and correct it when I get the braces off?
