Invisalign Trays No 23/52! Again I have felt almost no pressure from the upper tray – and do wonder if the arch is actually being widened at all as planned – it is very hard to tell and after 10 months now, it is the one area that is difficult to see improvement to the molar positions.  I have got a little lazy and especially with so many Christmas mince pies and bubbles being consumed, the trays have been out more than in. I am soooo glad I do not have to deal with the power chains associated with lingual braces that my friend is having to contend with that stained over time. I just now am waiting to get to the half way mark – that is February  time, and it will be huge boost to my moral to get there – can’t wait to get over the half way milestone. What did throw me a few weeks ago was my dentist now saying that I could have a replanned treatment with no IPR arghhhhh- it could extend treatment by a year!!!!! Apparently this was not an option when I started the Invisalign treatment plan. I am torn as do not think having any enamel stripped off your teeth can be a good thing – but I can’t face another year of plastic. Dilemma – any shared experience on this would be really welcomed please – does IPR risk sensitivity and decay?
