Dental Cavities - Causes Tooth decay, or dental caries, is a disease of the teeth which results in damage to the tooth structure. The cavities formed because of dental caries are called dental cavities. Unbeknownst to most, it is one of the most common of all human disorders, and is second only to the common cold! Although cavities typically occur in children and young adults, the condition can affect any person. For parents, it is important to remember that tooth decay is the most important cause of tooth loss in younger people; so ensure that your children take care of their teeth! What causes this tooth decay? Certain bacteria are normally present in the human mouth. The bacteria convert foods (especially sugar and starch) into acids. Bacteria, acid, food debris, and saliva combine in the mouth to form a sticky substance called plaque that adheres to the teeth. It is most prominent on the grooved chewing surfaces of back molars, just above the gum line on all teeth, and at the edges of fillings. Plaque that is not removed from the teeth mineralizes into calculus (tartar). Plaque and calculus irritate the gums, often resulting in gingivitis and ultimately periodontitis. The acids in plaque dissolve the enamel surface of the tooth and create holes in the tooth (cavities). Cavities are usually painless until they grow very large inside the internal structures of the tooth (the dentin and the pulp at the core) and can cause death of the nerve and blood vessels in the tooth. If left untreated a tooth abscess can develop. Plaque and bacteria begin to accumulate within 20 minutes after eating (the time period when most bacterial activity occurs). If plaque and bacteria are left on the teeth, cavities can develop, and untreated tooth decay can result in death of the internal structures of the tooth and ultimately the loss of the tooth. Dietary sugars and starches (carbohydrates) increase the risk of tooth decay. The type of carbohydrate and the timing and frequency of ingestion are more important than the amount. Sticky foods are a lot more harmful than non-sticky foods because they remain on the surface of the teeth. It is important to note as well that frequent snacking increases the time that acids are in contact with the surface of the tooth. CLICK HERE FOR THE BEST DENTAL PLANS |
