Long teeth
One of the early symptoms is the visible lengthening of your teeth. When gums recede because of periodontal disease, the teeth have the appearance of being much longer than normal. This can also be accompanied by the appearance of black spaces or gaps between your teeth.
Exposed roots
Exposed roots are another symptom and can be extremely sensitive and uncomfortable. They are often a sign of periodontal disease, or can be attributed to brushing too aggressively with a toothbrush with hard bristles.
Loose teeth
When you are suffering from receding gums you may notice your teeth become loose, which can be attributed to bacteria and periodontal disease under your gums around your teeth. As receding gums worsen, the gum pockets deepen due to the loss of an attachment structure.
