hello visit the dentist and get it checked.if the treatment is required you can get a consent from your physician and then start with your treatment.

Hi. If all your root canal treatment have been done properly and If those teeth are covered with a crown then there is no reason for you to worry. Since you are planning for pregnancy it is highly recommended that you visit a dentist now to check for your oral hygiene status and to get full mouth cleaning and polishing of your teeth done as there is a tendency of swelling of gums and bleeding from gums in pregnant females of they have existing gums disease. Also it will help you to find any new decay in your mouth and enable you to do a filling in time to prevent any further root canal. Regards, Dr Varun Bhatia
