Dental Researchers Test No-needle Anesthesia, No-drilling Cavity Care

Imagine having a decayed tooth repaired, painlessly, without drilling or shots of anesthesia to numb the area. Wishful thinking? Not if two studies being conducted at the University at Buffalo’s School of Dental Medicine show positive results. In one study, funded by a $100,000 grant by Apollonia, LLC, researchers in the school’s Center for Dental Studies are testing a nasal spray that numbs the upper teeth. “If this study is successful,” said Sebastian Ciancio, D.D.S., principal investigator on the study, “it may mean the end of dental injections when dentists are performing procedures on the upper arch.” The second study, set to begin in coming months, will test the use of ozone to kill bacteria in a decayed tooth and its potential to eliminate the need for the dreaded drill, at least to repair simple cavities. Researchers at UB and […]

Improper Consumption Of Acidic Foods Could Lead To Destroyed Enamel

Fruit, yogurt, citric and soft drinks, may seem like harmless snacks and beverages, but improper consumption and overuse may lead to devastating and permanent damage to teeth. It’s known as tooth erosion, the break down of tooth structure caused by the effect of acid on the teeth that leads to decay. According to David Bartlett, BDS, PhD, who will lead a discussion at the Academy of General Dentistry’s 55th annual meeting in San Diego, titled, “Acid Erosion-Why is it Important to My Patients?”, “Early diagnosis and prevention of the effects of tooth erosion are fundamental to keeping teeth healthy for life.” “Sipping or holding acidic drinks in the mouth before swallowing increases the risk of erosion on dental enamel,” says Dr. Bartlett. Dental enamel is the thin, outer layer of hard tissue that helps maintain the tooth’s structure and shape […]

Teen Tooth Trauma Prevalent In Ontario

Nearly one in five Ontario Grade 8 students shows evidence of damage to his or her front teeth, says a new University of Toronto study. This the first study of dental injury done in Ontario, says David Locker, a professor with the U of T Faculty of Dentistry. Similar studies have been done in other countries because tooth trauma is considered one of the most severe conditions children can experience. “Once you break an anterior tooth, you carry that with you for life,” says Locker. “Although it can be treated, there’s a likelihood you’ll need to repeat that treatment every 10 years. The cost of initial treatment can be quite high, depending on the injury, and the lifetime cost is estimated to be as high as $250,000 for four teeth.” Locker and his research team examined a random sample of […]

Root Beer – The Safest Soft Drink for your Teeth

Exposing teeth to soft drinks, even for a short period of time, causes dental erosion—and prolonged exposure can lead to significant enamel loss. Root beer products, however, are non-carbonated and do not contain the acids that harm teeth, according to a study in the March/April 2007 issue of General Dentistry, the AGD’s clinical, peer-reviewed journal.  That might be something to consider during the next visit to the grocery store. Consumers often consider soft drinks to be harmless, believing that the only concern is sugar content. Most choose to consume “diet” drinks to alleviate this concern. However, diet drinks contain phosphoric acid and/or citric acid and still cause dental erosion—though considerably less than their sugared counterparts. “Drinking any type of soft drink poses risk to the health of your teeth,” says AGD spokesperson Kenton Ross, DMD, FAGD. Dr. Ross recommends that […]

Impacted wisdom teeth cause numbness in your tongue and lower jaw

Impacted wisdom teeth can cause a variety of problems, including numbness in the jaw and the tongue. However, this is uncommon. Impacted lower (mandibular) wisdom teeth are often very close to a large nerve (inferior alveolar nerve) that controls feeling (sensation) to the lower jaw, teeth and tongue. Treatment of impacted wisdom teeth typically involves their surgical removal (extraction). This procedure may cause temporary numbness in your jaws, tongue and teeth. However, numbness in the lower jaw and tongue before surgical removal of impacted wisdom teeth is unusual and may indicate a problem that requires further evaluation. In some cases, impacted wisdom teeth can be associated with cysts and tumors — usually noncancerous. Other types of growths also can occur in the jaw area and result in the symptoms you describe. Consult your dentist about the numbness you’re experiencing. A […]
