Pregnancy toothache relief

I am 32 weeks pregnant with my first child and I sadly have a terrible toothache that I will get handled a little. I tried Orajel, cold water, warm water, compress - you name it and nothing helped, some things that make it much worse. This morning it was so bad that I end up looking online for the treatment of desperate house and found several articles about BAKING SODA. Yes Arm & Hammer Baking Soda. I'm so desperate I tried it. I mixed 2 teaspoons in a half glass of warm water and stir til dissolved powder. I wash my mouth several times using the contents of the glass. Having a sensation / tingling burning, not painful. Then I take a Q-tip and wet the tip and make a paste with soda and put it directly on teeth to make sure I get in between teeth. And the pain was gone almost instantly. I dont know if you all have experienced toothache really bad but I havent slept or eaten in 2 days. I do not know if I will make another day. I do not believe the results! After about a minute I rinse my mouth with warm water becuz I do not want to swallow the paste. But she believed me when I say - if you have a toothache BAKING SODA use !!!!!! I wish I had been looking for this earlier.
