Toothache?

Summer

I'm 7W2D today and randomly last night my tooth started aching pretty bad. I was recently at the dentist and had no cavities or anything so it seems strange. Did some googling and read that sometimes it can happen in early pregnancy. Just don't know if I have to go back to the dentist or if it will just pass. Sigh. Anyone else getting toothaches for seemingly no reason in 1st trimester?
