What Are Microbeads In Toothpaste?

People curious about microbeads in toothpaste

Scientists are continually looking for new ways to improve oral care products, and using microbeads in toothpaste used to be a popular method of adding abrasive qualities to the product. Now that microbeads have been banned, you can rest assured that you can find a toothpaste that works effectively for you and doesn't harm the planet. Learn why the eradication of microbeads spells good news for your health and the environment's health, too.

What Are Microbeads?

The Australian Department of Environment and Energy defines microbeads as "small, solid, manufactured plastic particles that are less than 5 millimeters and don't degrade or dissolve in water." They are an ingredient in a variety of personal care products and have a few different purposes. Microbeads are used as an exfoliant or abrasive agent, they allow for a timed release of active ingredients, they add bulk to personal care product formulas and they may prolong a product's shelf life. These capabilities, plus the inexpensive manufacturing costs, may account for this ingredient's popularity.

The Environmental Issue

Because microbeads aren't biodegradable, they pose a significant environmental concern. Research from the New York State Office of the Attorney General shows that microbeads can escape undetected into rivers and oceans after being washed down the drain, since their small size means they often aren't captured by regular sewage treatment systems. The report found that approximately 19 tons of microbeads are washed down New York drains each year!

The beads can be mistaken as food by fish, birds and other wildlife. When animals fill their stomachs with microbeads, they may spread the plastic up the food chain. This can lead to contamination of the fish we eat, since microplastics soak up pollutants in waterways, according to the Australian Department of Environment and Energy. Once in the environment, microbeads are almost impossible to remove.

Alternatives

The good news is that the U.S. Food and Drug Administration has addressed the issue. Thanks to the Microbead-Free Waters Act of 2015, the manufacturing, delivery and sale of any rinse-off products containing microbeads smaller than 5 millimeters have been outlawed. This ban extends to cosmetics, toothpastes and over-the-counter drugs. Many manufacturers have replaced microbeads with sustainable, biodegradable options, such as crushed nut shells and apricot kernels, according to the New Zealand Ministry for the Environment.

Toothpaste Abrasivity

If you previously turned to a toothpaste with microbeads because of their potential abrasive properties, there are plenty of other toothpastes available. Abrasive toothpastes are often used for their ability to scrub surface stains from teeth. But choosing a toothpaste that's too abrasive, or using a hard-bristled toothbrush, can wear down the outermost layer of your teeth called the enamel.

That's why it's important to search for an American Dental Association Seal of Approval when shopping for toothpastes. The ADA Seal of Approval is only awarded to toothpastes with a relative dentin abrasivity (RDA) score of 250 or less, ensuring that the toothpaste won't harm your enamel.

With microbeads banned from toothpastes for good, you can browse the personal care aisle with confidence that you'll find a product that cleans your teeth effectively without negatively affecting the environment.

Common Conditions During ADULTHOOD

As we get older, dental care for adults is crucial. Here are a few of the conditions to be aware of:

Gum disease – if your home care routine of brushing and flossing has slipped and you have skipped your regular dental cleanings, bacterial plaque and tartar can build up on your teeth. The plaque and tartar, if left untreated, may eventually cause irreparable damage to your jawbone and support structures, and could lead to tooth loss.

Oral cancer – according to the National Institute of Dental and Craniofacial Research, men over the age of 40 have the greatest risk for oral cancer. About approximately 43,000 people will be diagnosed with cancer of the mouth, tongue or throat area, and the ACS estimates that about 7,000 people will die from these cancers. The use of tobacco products and alcohol increases the risk of oral cancer. Most oral cancers are first diagnosed by the dentist during a routine checkup.

Dental fillings break down – fillings have a life expectancy of eight to 10 years. However, they can last 20 years or longer. When the fillings in your mouth start to break down, food and bacteria can get underneath them and can cause decay deep in the tooth.
