Hey hun, i work in a dentist and its really nothing to be worried about. Temporary fillings rarely fall out because they are still quite strong and if they did fall out you wouldn’t even notice them. so many patients we see swallow fillings without noticing because they are so small, so don’t worry about choking! I’m sure they will stay in place just fine – it will take a hell of a lot of force to make any fillings fall out lol xx
