Increased risk of aging: worn teeth don't look just different, but they are actually more prone to decay and decay. This is because the worn teeth lose some of the enamel -- the hard protective layer, covering your teeth and preventing the bacteria from entering the rest of the tooth. The layers below the enamel, the dentin, are less strong, more porous, and more exposed.
Uneven bite: when teeth lost their natural shape, you bite marks will change, as the tooth wear, more teeth will wear over time - because we all teeth are as a system work together, rarely only is the effect of a tooth. A bite that can lead to more grinding and occlusion in your sleep will only make the wear worse. A bite can also cause a lower jaw, headache, and other facial and neck muscle pain.
Facial changes: if your teeth are badly worn and a large portion of your teeth are missing, then your lower half of your face will appear shorter, especially if your mouth is closed.
