Invisalign Trays No 30! Well finally no 30/50 so I am positively middle aged with this thing. The tightness of the trays seems to really vary from set to set, and this set feel incredibly loose again, after pinch tight no 29. 2 more weeks and then I am getting my 3D scan (I hope rather than the “goo” set) and a mid course adjustment – hurrah! This means that I may have to wear this set for 2 weeks + 3 weeks – so my only concern is that is how to keep them really clean and fresh with 5 weeks of wear. I am going to avoid the strong cleaning products on the market as I am far too nervous about getting an allergic reaction, so I will just have to keep dunking them in the listerine and water cocktail. My mother actually commented on how nice my teeth were looking, so big smiles all round. My only concern at this stage is what the mid course correction might lead to, and how many additional attachments and additional weeks treatment I might need. Whilst I have got used to these things I have been rebelling recently and had them out all day this week, so must not slack off too much when I have invested so much over the past year. Keep smiling……….
