Microplastics & Your Mouth: What CU Anschutz Research Means for You

TL;DR: New research from CU Anschutz is raising questions about microplastics and oral health, prompting a look at how you can reduce exposure in your daily life.

Last updated: October 12, 2026

Emerging research from the University of Colorado Anschutz is shedding light on a growing concern: the potential impact of microplastics on our oral health. While the full scope of this issue is still being explored, the findings are prompting a closer look at our daily habits and environments. These tiny plastic particles, found in everything from water bottles to cosmetics, are increasingly ubiquitous. Scientists at CU Anschutz are investigating how these microplastics might interact with our mouths, from our teeth and gums to the broader oral microbiome. This exploration is crucial for understanding potential long-term health implications. Given these developments, it’s a good time to consider practical steps you can take this week to potentially minimize your exposure. Simple changes can make a difference in your daily routine. One immediate action is to be mindful of single-use plastics. Opting for reusable water bottles and food containers, and choosing products with less plastic packaging where possible, can reduce the amount of plastic waste that eventually breaks down into microplastics. Another area to consider is your personal care products. Many items, like toothpaste and scrubs, can contain microbeads, which are a direct source of microplastics. Checking ingredient lists and opting for microbead-free alternatives is a straightforward step. For those in San Antonio, Texas, if you're considering professional dental care to address any emerging oral health concerns, it's wise to discuss this research with your dentist. You might ask a licensed, insured dental professional: "Are there any new oral hygiene practices recommended given the growing concern about microplastics?" and "What signs should I watch for that might indicate an issue related to environmental particles in my mouth?"

Taking proactive steps now, even as research unfolds, can contribute to your overall well-being. If you're in the San Antonio area and want to ensure your oral health is in top shape, scheduling a dental appointment is a helpful suggestion.
