Estrogen oral contraceptives can have negative effects on periodontal health. While pills with a high estrogen content have been traditionally associated with these negative impacts, there have been recent studies linking modern low-estrogen pills to periodontal disease. Increasing attachment loss, as reduction of the connective tissue surrounding the tooth, has been noted, with a study published in 2007 finding that twice as many patients with aggressive periodontal disease were pill users.* These women tended to have higher levels of plaque, gingivitis and bleeding upon probing, although differences here were not statistically significant.
Because of these potential side effects, it is important to inform your dentist of all the medications you are currently taking, making sure to mention changes in your overall or dental health from the time of your last visit.
