In most dental offices, after the hygienist cleans your teeth, the dentist comes in to examine your teeth. Then, out of nowhere, he or she starts rattling off alpha-numeric jargon like, 3MOD, 5DO, 13MFD and so on. The dentist is not looking at a bowl of alphabet soup, but, rather, using a form of dental shorthand. The numbers represent which teeth have cavities or other problems. Tooth number one is the upper-right third molar or wisdom tooth, the farthest tooth back in the mouth. Tooth number 16 is the upper-left third molar. Tooth number 17 is the lower-left third molar, and tooth number 32 is the lower-right third molar. So, teeth eight and nine are the upper-front teeth, or the left and right central incisors, and teeth 24 and 25 are the lower-front teeth, or lower-left and right central incisors.

To understand how a cavity works, we need to have a basic understanding of the anatomy of the tooth. A tooth is composed of several layers. The outermost layer (above the gum line) is called the enamel. Enamel is the hardest and most mineralized substance in the body. Beneath the gum line, a substance called cementum covers the tooth roots. Under the enamel and cementum is the dentin. The dentin is about as hard as bone, and, unlike the enamel, dentin contains nerve endings. Beneath the dentin is the dental pulp. The pulp is a vascular tissue composed of capillaries, larger blood vessels, connective tissue, nerve fibers, and cells including odontoblasts, fibroblasts, macrophages and lymphocytes. The pulp is needed to nourish the tooth during its growth and development. After a tooth is fully mature, the only function of the pulp is to let us know if it is damaged or infected by transmitting pain.

Studies on the link between periodontal disease and preterm birth have produced conflicting results. Although some show that women with gum disease are more likely to deliver a baby before term — which sets up the baby for health risks — others have not found a link. Studies are ongoing.
Despite those conflicting results, other research has found that treating periodontal disease in pregnant women helps them carry their infants to term. In a recent study, researchers found that women with periodontal disease who completed periodontal treatment before the 35th week were less likely to deliver their babies before term than those with periodontal disease who did not get treatment.
