Advice for teeth during pregnancy

I don’t have any kids yet. I want to soon. One of the reasons I’m super nervous about being pregnant is because of my teeth.

I have always had issues with my teeth. I get cavities easily. And I recently found out that I have gum disease. I do brush my teeth twice a day. But I do eat a lot of sugary foods and drink soda.

I’ve heard that pregnancy can cause problems with your teeth. But since I have issues already, I’m worried I’m gonna lose all my teeth.

Did you have any issues when you were pregnant and do you have any advice on this ???
