If plaque or calculus is not removed.

If plaque or calculus is not removed, the bacteria cause inflammation of the gums called gingivitis. In gingivitis, the gums become red, swollen and may bleed easily. Gingivitis is a mild form of gum disease and is usually reversible with daily brushing and regular cleaning by a dentist. This form of gum disease does not include any loss of bone and tissue that holds teeth in place. When gingivitis is not treated, can advance to periodontitis. In periodontitis, gums backs out of the tooth forming pockets that become infected. The body's immune systems resist the bacteria when the plate is scatters and grows under the gum line. Bacterial toxins and enzymes that attack the body infection usually start under the broken bone and connective tissue that holds the tooth in place. If left untreated, bones, gums and connective tissue that supports the teeth is destroyed. The teeth will eventually loosen and have to be removed.
