Chew on This: How Losing Teeth Might Weaken Your Memory

by

We’ve all heard that “you are what you eat,” but new research suggests that how you eat might be just as important for your brain. A fascinating new study from Hiroshima University, published in Archives of Oral Biology, has revealed a startling connection between tooth loss and cognitive decline. It turns out that losing your molars doesn’t just change your smile—it might actually be shrinking the memory centers of your brain. The Study: Chewing vs. Nutrition For a long time, scientists noticed that people with fewer teeth often suffered from memory issues. The common theory was that tooth loss led to a poor diet (like eating less protein), and that lack of nutrition caused the brain to suffer. To test this, researchers at Hiroshima University studied aging mice. They split them into groups to see what mattered more: the physical … Read more

A New Ally Against Pain? Magnesium Shows Promise After Wisdom Tooth Surgery

by

The discomfort following wisdom tooth extraction is a familiar challenge for many. While nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are the go-to for pain relief, researchers are continually searching for ways to enhance comfort and recovery. Exciting new findings suggest that a common supplement, magnesium, could be a valuable addition to the post-surgical pain management regimen. A recent study published in Pain Research and Management titled “The Effect of Oral Magnesium Supplement on Postoperative Pain Following Mandibular Third Molar Surgery: A Split-Mouth Randomized Placebo-Controlled Trial” (Sutthipat Nimkulrat and et. al. Jan. 23, 2025) indicates that combining an oral magnesium supplement with NSAIDs can significantly reduce pain at rest 24 hours after third-molar surgery. The study delves into magnesium’s potential as an analgesic adjuvant. Magnesium is known to block N-methyl-D-aspartate receptors, a mechanism that has shown promise in managing postoperative pain … Read more

Wisdom Tooth Dilemma: Orthodontists Grapple with Prophylactic Extraction Decisions

by

For many young adults, the discussion of wisdom tooth removal comes hand-in-hand with orthodontic treatment. Often, these “third molars” are extracted preventively, driven by concerns about impaction, potential crowding, or even future complications. Yet, despite how common these discussions are, a surprising lack of consensus exists among dental professionals regarding the proactive removal of asymptomatic wisdom teeth. A recent study published in the American Journal of Orthodontics and Dentofacial Orthopedics titled “Factors influencing prophylactic extraction of mandibular third molars in orthodontic practice: A cross-sectional study” (Hila Ziv-O et. al. Volume 167, Issue 6, pp. 673-680 mJune 2025) sheds light on this variability, underscoring the need for clear, evidence-based clinical guidelines. The research aimed to explore the factors influencing these crucial decisions among orthodontists in Israel. Through an online survey conducted in July 2024, 88 active orthodontic specialists and residents provided insights into … Read more

Hydrocortisone Shows Promise in Reducing Pain and Swelling After Wisdom Tooth Removal

by

An interesting article titled “Efficacy of Hydrocortisone, Povidone-Iodine, and Normal Saline as an Irrigating Solution During Surgical Removal of Impacted Mandibular Third Molars: A Randomized Controlled Trial” written by Faheem Ahmed and et. al. appears in Cureus published February 01, 2024. The study sought to compare the effects of three irrigating solutions, hydrocortisone, povidone-iodine, and normal saline, on pain, trismus, and edema following removal of impacted lower wisdom teeth. Wisdom tooth removal, also known as the surgical removal of impacted third molars, is a common dental procedure, often accompanied by pain, swelling (edema), and difficulty opening the mouth (trismus). Researchers have been looking for ways to alleviate these post-surgical concers. The study metnioned in this article compared the effectiveness of three irrigation solutions used during surgery. The study involved 105 patients between the ages of 18 and 40 who needed … Read more

Stannous Flouride Combination Can Eliminate Dental Cavities

by

An interesting article titled “Iron oxide nanozymes stabilize stannous fluoride for targeted biofilm killing and synergistic oral disease prevention” written by Yue Huang and et. al. appears in Nature Communications, vol. 14, No. 6087, 2023. The article discusses a potent therapeutic synergism using approved agents while providing facile stannous fluoride stabilization, to help prevent oral disease and dental caries (cavities). The authors describes a new method for using iron oxide nanozymes to stabilize stannous fluoride and improve the ability to kill biofilms. Biofilms are communities of bacteria that can form on teeth and other surfaces in the mouth. They are difficult to remove and can lead to tooth decay and other oral diseases. Stannous fluoride is an effective antimicrobial agent, but it is unstable and can be difficult to deliver to the site of infection. Ferumoxytol, an iron replacement, stabilizes stannous fluoride … Read more
