See Section 4 here:

(I suggest that the references to 'muscle, bone disorders and painful periods' might be those closest to dental pain).
Hank you...I've been given a prescription for antibiotics by the doctor, (cant get hold of the dentist) hoping the antibiotics soon kick in, I take 1 naproxen in the morning and 1 in the evening anyway, for the Arthritis, and I just wondered if I could take 1 extra naproxen at lunchtimes until the tooth pain subsides.
Thank you, yes they are 500mg my pack does also says 2 a day which is what I usually take, but if I take with a meal I hoping one extra for a couple of days wont hurt to much.
