These wedge-shaped grooves near the gumline are called abfraction lesions—a type of non-carious cervical lesion (NCCL). They're caused by tooth flexure from grinding (bruxism) or a misaligned bite, which creates microfractures in enamel and dentin. Over time, abrasive brushing or acidic exposure can worsen the damage. Even if painless, they weaken tooth structure, trap plaque, and may lead to sensitivity or fractures. Treatment involves correcting bite forces (e.g., night guard), gentle brushing, and possibly restoring the area with composite or glass ionomer. Early management preserves tooth health, prevents complications, and avoids more invasive treatments later.

Dentistry is one of the world’s oldest medical professions, dating back more than 9,000 years.

The earliest records of dentistry date to 7000 BCE

By 5000 BCE, Sumerian texts mentioned tooth decay, attributing it to "tooth worms"— an idea that wasn't debunked until the 1700s.

In 1840, the first dental college opened in the U.S., soon followed by the formation of the American Dental Association.

Harvard founded the first university-affiliated dental school in 1867. Meanwhile, dental innovations emerged, such as Colgate’s mass-produced toothpaste in 1873 and toothbrushes soon after.

Interestingly, good oral hygiene wasn’t widely practiced in the U.S. until after World War II, when soldiers brought back brushing habits from abroad.

Research shows Alzheimer’s disease may be linked to an unexpected culprit — gum disease.

A study discovered the presence of Porphyromonas gingivalis, a bacteria responsible for chronic periodontitis, in the brains of deceased Alzheimer’s patients.

Researchers found that when mice were infected with the bacteria, it colonized their brains and triggered the production of amyloid beta, a protein commonly associated with Alzheimer’s. This evidence strengthens the hypothesis that the disease could have infectious origins rather than being solely a neurodegenerative disorder.

The study also revealed that toxic enzymes from the bacteria were present in individuals who had Alzheimer's-related brain changes but had not yet been diagnosed with dementia, suggesting the infection may begin years before symptoms appear.

This discovery opens the door to new potential treatments. A pharmaceutical company, Cortexyme, developed a compound called COR388, which showed promise in reducing both bacterial infection and amyloid beta accumulation in animal trials. While human trials are needed to confirm its effectiveness, the study underscores the importance of oral hygiene in brain health. Scientists remain cautiously optimistic, emphasizing that with no new dementia treatments in over 15 years, investigating all possible causes is crucial. While more research is needed, the link between gum disease and Alzheimer’s highlights a simple yet vital message: taking care of your teeth might help protect your brain in the long run.
