Toothaches

Not really sure if this is the best place for this post but I’m going to try. I have supper sensitive gums and teeth. Every time I brush my teeth I get really bad toothaches two sometimes three times a week. I have tried every kind of toothpaste and toothbrush out there but no matter what kind I use I always get these toothaches. Right now my left tooth right before my left molar is throbbing in pain. I tried orajel but it made me drool so much I ended up spitting it all out. I’m going to go see a dentist once my son is born (I’m 7 months due may 16th) but is there anything I can do in the meantime to manage the pain? Is anyone going through something like this? Or went through something like this?
