I almost decided not to switch to these Invisalign trays on the basis that I have a seriously sore throat. But. But. But. The ever nagging little voice in my head that thinks that my teeth will end up going back 5 stages if I don’t complete this thing properly keeps telling me that I need to follow all the instructions exactly to the letter, so switch I did. I figured that the panadol would probably help my throat too, right?
