Weird question....

I had a miscarriage in June at 6 weeks. I have had normal pregnancies with healthy children in the past. So I was completely devastated and shocked when I miscarried..... of course I feel like something could be wrong with me.... So my brain has gone crazy thinking of all the what if’s....

Has anyone ever heard of a miscarriage caused by an oral/tooth infection? I have a cracked tooth that needs a filling. And of course I’m thinking to myself “ hmm, what if u have an infection and it caused a miscarriage 🤔”...... But now I’m wondering if anyone has experienced this or heard of it? I do not have any pain, swelling or signs of infection for that matter. Thanks in advance!
