I’m really torn on what to do and I need opinions.

I will be 28 weeks tomorrow, I am considered what my doctors called “high risk, but on the lesser scale” because I had a premature baby my last pregnancy and they never determined why because labor progressed so quick (baby made it to 35+6). I made an appointment with a dentist for tomorrow but now I am rethinking it. I have cracks going across one tooth (but nothing actually broken off or going all the way through the tooth yet) and what feels like a deep cavity on the tooth next to it on the side. Neither hurt yet.

On one hand, I’m scared to do it now because I have dental anxiety and usually use laughing gas.

On the other hand, I want to get it done because I feel like I’ve been stressing about it for a little while and will just continue to until after baby. And I don’t want to have to try to be giving birth with a bad tooth ache or get to a bad point
