How Do Dentists Detect Cavities?

admin — Tue, 24 Nov 2009 12:26:03 +0000

Cavities are detected a number of ways. The most common are clinical (hands-on) and radiographic (X-ray) examinations. During a dental exam, the dentist uses a handheld instrument called an explorer to probe the tooth surface for cavities. If the explorer “catches,” it means the instrument has found a weak, acid-damaged part of the tooth — a dental cavity. Dentists can also use a visual examination to detect cavities. Teeth that are discolored (usually brown or black) can sometimes indicate a dental cavity.

Dental X-rays, especially check-up or bitewing X-rays, are very useful in finding cavities that are wedged between the teeth or under the gum line. These “hidden” cavities are difficult or impossible to detect visually or with the explorer. In some cases, none of these methods are adequate, and a dentist must use a special disclosing solution to diagnose a suspicious area on a tooth.

Gum Disease and Premature Birth

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.

Periodontal Disease and RA

Rheumatoid arthritis (RA) is an autoimmune disease marked by inflammation and painful joints. People with RA are more likely to have periodontal disease, and one study found that they had more missing teeth than people who don’t have RA.

Chronic inflammation is common to both conditions. Although scientists haven’t found evidence that one condition causes the other, a 2009 study found that people with a severe form of RA had less pain, swelling, and morning stiffness after their periodontal disease was treated.
