This inflammation is caused directly by plaque which forms each day on everyone's teeth. Plaque is the colorless, sticky film of organized bacteria which live and grow on the surfaces of teeth. When this growth is not mechanically interrupted by proper brushing and flossing, the byproducts of plaque irritate the gum tissue. The body then forms a defense of certain cells which fight against these irritants. This process results in inflammation.
Inflammatory changes affect the gum tissue adversely.
Unfortunately, most folks don't realize the problem because there is no pain associated with this type of inflammation in most cases. Warning signs include red, irritated gums that bleed easily. Your dentist will check your gums for gingivitis at your exam and assist you in treating it. Fortunately, gingivitis is reversible. If diagnosed, it can be effectively treated.
