Pregnany is NOT a contraindication to dental treatment, although it's best to defer elective dental work (ie. cosmetic procedures) until one has given birth. In your case, since you have a severe tooth ache, your body responds to this "stress" by releasing excessive norepinephrine, epi, and cortisol. This is turn may cause your body suffer unnecessary systemic stress, and may also influence placental function. The best course of action is to resolve the pain source, which then relieves the excess epi, norepi, and cortisol output.
The x-rays are focused on your oral cavity; the percentage of scatter radiation to your abdominal area is low to begin iwith. Since you were double shielded, you fetus probably absorbed as much radiation from that x-ray as from walking around outside for a few minutes.
Penicillin is a FDA pregnancy category B drug, which means it either has not been shown to have confirmed adverse human effect in the first 1st trimester and no evidence of risk in the 2nd and 3rd trimesters, OR animal studies have not demonstrated fetal risk. In other words, pen VK is a safe drug.
