Teeth issues with pregnancy

I have never been pregnant but I am planning with my bf to have a child soon.

I am a little scared about dental problems with pregnancy. I have always had issues with my teeth. When I was younger , I had crooked teeth and needed braces. And as I got older, my teeth have gotten cavities easily. I always brush my teeth and go to the dentist often. But my teeth are not the healthiest.

I recently found out that my mom actually lost her teeth when she was pregnant with me. And she has dentures.

I have researched it a lot and since my teeth are not the strongest, I’m worried about having issues or losing my teeth during pregnancy.

Have any of you ladies dealt with that? Any advice ??
