We Asked Experts: Are Teeth Aligners Safe?

By Lan Pham, Kaelyn Johnson, MPH, RD
Thinking about getting teeth aligners and wondering if they’re safe? Read on for more about teeth aligner safety and what experts have to say about the devices.

If you’re looking into options for straightening your teeth, you may be asking yourself, are teeth aligners safe? Researchers are actively studying teeth aligners in regards to a number of factors, including safety. But there’s already evidence that aligners are safe. In fact, the devices could even improve your dental health.

Teeth Aligners and Your Dental Health

Invisible teeth aligners are often used as an alternative to braces. They are snug, clear, mouthpieces that fit directly over the teeth. Typically, they are made of plastic or acrylic material. Unlike braces, they can be removed for activities like eating, flossing, and brushing your teeth—making it easier to maintain a clean mouth.  

You can typically use teeth aligners for mild-to-moderate straightening needs as well as minor issues with spaces between the teeth. Correcting these problems can improve your overall dental health, as straightened teeth are easier to clean. Another benefit of teeth straightening is decreased amounts of bacterial accumulation in your mouth. 

But are teeth aligners safe? “Teeth aligners, when under the direct supervision of an orthodontist, are indeed safe and highly effective at achieving tooth movement,” Greg Asatrian, DDS, MS, tells WebMD Connect to Care.

There is also evidence that using teeth aligners can even promote better dental health. A 2014 systematic review published by the European Journal of Orthodontics found that clear aligner users experienced significant improvements in their periodontal health. This means that the supporting structures of their teeth demonstrated health improvements as a result of aligner treatment. 

There are a number of online teeth aligner providers. Choosing a provider that offers orthodontist or dentist supervision throughout your treatment is the best way to ensure your safety.
