Liz. Invisalign. Day – lost count right now…..Back to the dentists yesterday and pleased to say I have been given 3 sets of replacement trays treated in a different product, or in a “different way”…. I am not told more than that so don’t really understand exactly what Invisalign have done but I am keen to try. The lack of information from them is frustrating. My cough has nearly gone but I am left with acute pain on coughing or sneezing so back and forth to the doctors where yesterday I was given a course of antibiotics and sent off for a chest x ray. I won’t try the new trays until the course of antibiotics is finished and the x ray comes back all clear.  I just want to get on with the process now. I did ask my dentist if I cannot tolerate the new trays what my options are, and was surprised how he really pressed the invisalign as being the best treatment for me…..I had always understood that I was in some way compromising an optimal treatment plan because of my desire to want to have an invisable system, and the freedom to take them out of my mouth when I wanted. He stated that the ability of the Invisalign to expand the jaw (is that right?) was why Invisalign had an advantage over traditional railway tracks. He agreed I would probably struggle with lingual but needs might lead me to a hybrid solution. So for now I will wait another week then back to Tray Set No 2 treated in the new product (ugh going backwards) but NO Retainer Brite this time around either. In the meantime I am enjoying my cups of tea, diet coke and snacking galore whilst I can before the Invisalign diet is upon me once again.
