It's totally not a big deal. They move and when then do foods will taste different and feel different too. Like one week you'll love eating something, maybe pasta, but the next week it will gag you and you won't be able to stand even smelling it.
If you google it you'll see images of it and it's quite interesting to read about it. My granddaughter has it and before I decided to be a grownup and stop fighting about food with her she would take a bite of food that she loved and she'd gag and start puking it up. I didn't know what caused it. Their pediatric dentist noticed it and told me all about it. It's like a non issue most of the time. Don't worry about it. It comes and goes, nothing to do about it, it's not a big deal.
