Individuals with gingivitis can have red or purple colored gums. Healthy gums cover each tooth up to its neck, and are firmly attached to the jawbone. Healthy gum tissues cover and protect the roots of teeth. Gum tissues are known for being dense. The gums have a concentrated supply of blood vessel just below the mucous surface or moist gum surface. The gums have a deep, pink color. They are connected to the rest the mouth. The gum tissue may be damaged when the bacteria that cause gingivitis, which causes plaque on teeth, release toxic byproducts. This can trigger a response from the immune system. In response to the cellular damage, the immune system activates mechanisms that help repair and mediate tissue. The dilation of blood vessel in the affected region is one of the mechanisms used. The gums of an individual will turn red, purple, swollen and inflamed when the blood vessels that are concentrated in the gums dilate.
