Tooth problem while pregnant

Dee ay

So I’m 31 weeks pregnant is it normal to feel like I can slightly move my front tooth with my tongue sometimes! but when I move it with my finger it does not move I’ve been to the dentist she said nothings wrong with my teeth but because I have the beginning of gingivitis, I’m so annoying and paranoid that my tooth might fall out, never had this problem before with my first pregnancy anyone feeling the same thing ?
