(Concern) Is it okay to get cavity treatment during pregnancy?

I signed up for dental insurance.

I plan to get cavity treatment after one year because I can be covered then.

I have plans to have a baby by the end of this year, so if I need to get cavity treatment, I think I will do it during pregnancy.

Is it safe to undergo cavity treatment during pregnancy?

Is it dangerous if I don't use anesthesia like when extracting wisdom teeth?

I'm worried about this.

I have two dental insurances, one I will keep for life and the other is for cavity treatment and will be discarded afterward.

Should I have the baby and get cavity treatment even if it means taking a bit of a loss financially?

I'm 고민 whether to get a cavity treatment during pregnancy to avoid losing money.
