Very often, this is because you have not flossed in a long time. If it has been awhile, your gums may be sensitive, irritated or even bleed when you begin your flossing routine. This is perfectly acceptable. Once you begin flossing daily, your gums should no longer bleed. In the process you will be removing the plaque from in between your gums and your teeth, helping them to be in better health. At Mitchell Dental Spa we can show you how to floss your teeth properly to help ensure that you are getting a really good clean. Call (312) 642-1014 and let us know if your gums continue to bleed after a week of flossing daily.
