Inflamed gums

It’s odd I have amazing straight teeth, never had a cavity but I’m always having gingivitis come and go. Now with pregnancy hormones they’re puffy again.

I’m brushing 3 times a day, flossing, have a water pick etc and seems a bit better but not a huge dent. Thinking of going to get a cleaning BUT is any numbing agent they use bad for you ??? While pregnant ?? They’re sensitive I absolutely need them to numb
