You may find your gums bleed more easily while you are pregnant. This is caused by the increased blood supply to the oral tissues during pregnancy. You should brush at least twice daily using a soft toothbrush and floss daily.
It is recommended to continue routine dental care during pregnancy. If dental work is necessary, it is safe for the dentist to use a local anesthetic such as Novocain. Please inform your dentist that you are pregnant, and if X-Rays are required, they can be safely performed with the abdomen shielded.
