What causes tooth root resorption? A: A study on external root resorption in the journal Schweiz Monatsschr Zahnmed states that trauma, periodontitis, orthodontic treatment, internal bleaching, cysts, tumors or stimuli from a necrotic dental pulp may cause tooth root resorption.
Tooth decay is a common cause of tooth loss in younger people. Bacteria are normally found in your mouth. These bacteria change foods -- especially sugar and starch -- into acids. Bacteria, acid, food pieces, and saliva combine in the mouth to form a sticky substance called plaque. Plaque sticks to the teeth. It is most common on the back molars, just above the gum line on all teeth, and at the edges of fillings. Plaque that is not removed from the teeth turns into a substance called tartar. Plaque and tartar irritate the gums, resulting in gingivitis and periodontitis. Plaque begins to build up on teeth within 20 minutes after eating. If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth, and create holes in the tooth (cavities). Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture. An untreated cavity can lead to a tooth abscess.
