Can it take longer for gums to heal after teeth extraction if you have gum disease ?

It can...: Gum disease typically occurs when gum tissue is aggravated by excessive plaque and bacteria combined with poor oral hygiene. When gum disease is not managed, this can result in the delayed healing of surgical areas, not to mention an increased risk of infection. My best advise is to see your dentist and hygienist before any oral surgery.

Yes .: Due to high bacterial count because of gum disease the extracting site will be slow to heal. Some times you can end up with dry socket. Its very painful if not treated. Brushing properly and flossing is a must to keep the bacterial count down. Keep your dental appointment twice a year.

Yes: An infection if occurs will slow down the healing process. The most common infection in extraction is dry socket, a situation where an infection causing loss of the clot, exposing bone to outside environment and thus termed "dry socket". Gum disease would increases pathogenic bacterial counts in tissue, making the extraction site susceptible to bacterial invasion and causing infection.
