Although this type of tooth wear is considered part of the normal aging process, more rapid dental attrition may be due to larger dental problems. Overtime, if dental attrition is left untreated, it can wear away the enamel, exposing the dentin of the tooth. This can lead to tooth sensitivity and decay. • Dental erosion is the loss of the surface of your teeth due to acids you eat or drink, or acids coming up from your stomach. These acids can dissolve the crystals that make up your teeth, leading to tooth surface loss. These acids can also soften the tooth surface, making it easier for them to be worn away by abrasion or tooth grinding. This is known as acid wear. • This oral pathology consists of the wear and tear and weakening of the enamel, generally through a mechanical cause. Although the process initially affects the tooth structure, it ends up damaging the cervical area of the tooth as well. • Dental abfractions are v-shaped notches that appear near the gingival margin. These lesions are not caused by decay. Rather, they are the result of certain dental conditions, such as bruxism (teeth grinding).
