If a tooth is hurting, can i take antibiotics instead of having to do dental work?

Check with Dentist: For my OB patients that have dental/gingival infections or require antibiotics after a dental procedure, certain antibiotics are safe to take while pregnant. However, if your dentist/dental surgeon feel that the problem you have requires a dental procedure, antibiotics will not take the place of that. Continuing good oral hygiene during pregnancy with regular brushing and flossing is important.

Toothache: It depends on what is causing your toothache. Antibiotics can help if there is an infection like an abscess. If it is caused by a big cavilty or a crack, antibiotics will not help.
