Of course! I'm always happy to help
Beata's missing person case says that all of the teeth were her own. No dentures. No dental work mentioned (but then again, there isn't a lot of information mentioned there, not very helpful). It also mentions the town of Wejherowo as her last known place of residence in Poland. Not very helpful since she apparently went missing in the US.
Karolina, I'm very sorry your mum is missing. I hope you get some answers soon. Does your mum have a thread here? If not, it would be a good idea to start one. If you need help with talking to the Gdańsk police, I'm willing to help, I'm in Poland too. I'm also here for you if you need to talk.
