Pérdida de hueso por falta de dientes !!!

When a tooth is lost, the jawbone beneath it no longer receives stimulation from chewing. As a result, the body begins to break down the unused bone — a process called bone resorption.

Research shows that up to 25% of the jawbone can be lost within the first year if a missing tooth is not replaced. This bone loss mainly affects the alveolar bone, which supports the teeth, and it progresses most rapidly during the first 6–12 months.

Over time, bone loss can lead to shifting teeth, bite problems, facial changes, and difficulty placing dental implants later. What starts as a single missing tooth can gradually affect overall oral health.

Replacing missing teeth early — especially with options that restore chewing forces — helps preserve jawbone strength, facial structure, and long-term dental health.

Alzheimer’s may be linked to gum bacteria, new research shows.

Yes, the disease might not come from your brain at all — but a oral infection.

Emerging research suggests a surprising connection between gum disease and Alzheimer’s disease, offering a potential breakthrough in understanding—and possibly preventing—one of the most devastating brain disorders.

Scientists have found Porphyromonas gingivalis, the bacteria responsible for chronic gum disease, in the brains of deceased Alzheimer’s patients.

In lab experiments, mice infected with the bacteria developed hallmark Alzheimer’s features, including amyloid beta, a protein long associated with the disease. Even more striking, toxic bacterial enzymes were found in people with early brain changes linked to Alzheimer’s—well before any symptoms appeared—hinting that the infection may trigger damage years in advance.

This discovery is fueling hope for new treatments. One experimental drug, COR388 (developed by Cortexyme), has already shown promise in reducing both the bacteria and amyloid beta buildup in animal models. While more studies and human trials are needed, the findings support the idea that Alzheimer’s could have an infectious component, not just a degenerative one. For now, researchers are cautiously optimistic—but the implications are big: maintaining good oral hygiene could do more than preserve your smile; it might also help protect your brain.

Una investigación emergente sugiere que la enfermedad de Alzheimer puede estar relacionada con un culpable inesperado: la enfermedad de las encías.

Un estudio descubrió la presencia de Porphyromonas gingivalis, una bacteria responsable de la periodontitis crónica, en el cerebro de los pacientes de Alzheimer fallecidos.

Los investigadores encontraron que cuando los ratones fueron infectados con las bacterias, colonizaron sus cerebros y provocó la producción de beta amiloide, una proteína comúnmente asociada con el Alzheimer. Esta evidencia fortalece la hipótesis de que la enfermedad podría tener orígenes infecciosos en lugar de ser únicamente un trastorno neurodegenerativo.
