Is a toothache one of the signs of pregnancy?

Toothache. No. If you are sexually active please take all necessary precautions to prevent STDs and pregnancy. See your dentist as a toothache is a sign of a cavity in need of repair.
No. It's a sign of an abscessed tooth. Infection can harm your child if left untreated. Please put down the computer or PDA, pick up the phone, and call your Dentist for safe effective care.
No. I have never associated that as one of the signs of pregnancy. Sounds like it is time to visit the dentist.
