Exactly why I'm so confused about it. Also I've been living with my partner and his senior parents since 2020 as well. Even if I forgot somehow, one of them definitely would have remembered.
I found my copy of my x-ray I had when my son was about 6 months old, so I can definitely confirm I still had them in December 2019. My current dentist is absolutely lovely and always points out every little thing on my x-rays because he knows I'm nosy/curious which is how I even found out they're gone now.
My previous dentist isn't practicing anymore as far as I know, but I've been trying to track down where he went if he is. His clinic is definitely closed. Not sure if he just retired or left, or what is going ont here. No one remembers anything other than the set of 3 fillings I had to get in 2021.
I haven't gone down the rabbit hole yet of figuring out if maybe my insurance knows anything. Its on the list of stuff to do after I get everything sorted out that I was actually in for this time. The entire situation is just really weird to me. The only thing I can think of is that maybe when I got my fillings done, he also took my wisdom teeth for some reason, but I feel like I would have noticed and remembered the recovery at least?! My partner is going full conspiracy theorist with it and has a few wild ideas about it.
