I'm 32 f, and 21 weeks pregnant. I noticed a rough patch when I flossed for a few weeks to months maybe. However I flossed on Friday evening and a chunk of tooth/filling came away. Im not sure if it was filling or tooth, I've struggled with cavities since I was a young child so I've had many, unfortunately.

This is my question: can I use the temporary filling stuff like the CVS brand filling and crown temporary fix for basically a month. The reason I'm asking is because i don't have dental coverage until next month. I don't want to incur debt before my baby comes, but if it's debt or risk to my baby I'll go for debt. Any help would be great thanks.
