Is mouth tape regulated? How the FDA treats tapes, strips and sleep products

Nasal strips are regulated as Class I medical devices under their own FDA regulation, 21 CFR 874.3900. Mouth tape has no classification regulation written for it, so how the rules apply depends mostly on what a product claims to do. Low-risk products sold for general wellness, such as sleep management, fall under an FDA policy that doesn't examine them before sale.

That's less alarming than it sounds. Most sleep tapes and strips are simple, low-risk products, and the system is built to spend its attention on higher-risk ones. Here's how it works and what it means when you shop.

How does FDA decide what counts as a medical device?

FDA decides what counts as a medical device based on intended use. FDA says a product is a device if it meets the definition in section 201(h) of the Food, Drug, and Cosmetic Act. That includes an instrument or related article intended for use in the diagnosis of disease, or in the cure, mitigation, treatment or prevention of disease, or intended to affect the structure or any function of the body, without working mainly through chemical action.

FDA tells makers to define the intended use and indications for use of their product to decide whether it fits. In practice, that means the words on the box and the website matter a great deal. The same strip of tape can be described in ways that land it in different places.

What are the three device classes?

FDA has set classifications for about 1,700 generic types of devices, grouped into 16 medical specialty panels, and each type is assigned to one of three classes. Class I includes devices with the lowest risk and Class III those with the greatest risk.

FDA's consumer page gives examples. Class I devices such as elastic bandages, tongue depressors and exam gloves are subject to general controls only, and most are exempt from premarket notification. Many moderate-risk Class II devices are sold after 510(k) clearance, which means the maker showed the device is substantially equivalent to one already legally marketed. Class III devices generally need premarket approval.

How are nasal strips and nasal dilators regulated?

Nasal strips have the clearest answer. Under 21 CFR 874.3900, a nasal dilator is a device intended to provide temporary relief from transient causes of breathing difficulties resulting from structural abnormalities and/or transient causes of nasal congestion associated with reduced nasal airflow. The regulation says it decreases airway resistance and increases nasal airflow.

The same section describes the external version: one or more layers of material with a spring material attached and a skin adhesive that holds it to the nose, acting with a pulling action to open the nares. The internal version is metal or plastic placed inside the nostrils. Both are Class I (general controls) and exempt from the premarket notification procedures in subpart E of part 807, subject to the limitations in 21 CFR 874.9.

Those limitations matter. Under 874.9, a maker still has to submit a premarket notification if its device is intended for a different use than legally marketed devices of that type, or works using a different fundamental scientific technology. There's more on how the strips themselves work in how nasal strips work and nasal strips vs nasal dilators.

Is there a regulation for mouth tape?

There's no regulation written specifically for mouth tape. When we searched Title 21 of the eCFR, the federal rules the FDA works under, for the phrase "mouth tape" in October 2026, it returned no results. The nearest neighbor is 21 CFR 880.5240, medical adhesive tape and adhesive bandage, which covers a strip of fabric or plastic coated on one side with adhesive. That regulation lists its uses as covering and protecting wounds, holding together the skin edges of a wound, supporting an injured part of the body or securing objects to the skin. It's Class I and exempt from premarket notification, subject to limits.

Mouth tape isn't among those listed uses, and we're not going to guess how FDA would treat any particular product. What we can say is that the claims a brand makes are the main thing that shapes where a product sits.

For contrast, mouthpieces for snoring are regulated more tightly. Under 21 CFR 872.5570, intraoral devices for snoring and for snoring and obstructive sleep apnea, including tongue retaining and mandibular repositioning devices, are Class II with special controls.

What is FDA's general wellness policy?

FDA updated its guidance on general wellness products in January 2026. It says FDA's device center does not intend to examine low-risk general wellness products to determine whether they are devices, or whether they comply with requirements such as registration and listing, premarket notification and labeling.

To qualify, a product has to meet two factors: it's intended only for general wellness use, and it presents a low risk to the safety of users and others. The first category of wellness claims makes no reference to diseases or conditions, and the guidance names sleep management among them, alongside relaxation, stress management and physical fitness.

The guidance also sets limits. A product isn't low risk if it's invasive, implanted, or involves a technology that could pose a risk without specific regulatory controls. FDA adds that being Class I doesn't necessarily mean a product is low risk for this policy. And in plain words, it says a product's inclusion under the policy does not establish that it has been shown to be safe or effective for its intended use.

What do "registered" and "FDA approved" mean on a label?

"Registered" and "FDA approved" mean different things on a label. FDA says mere registration of an establishment or listing of a device does not denote approval of the establishment or the device, nor does it mean that a product may be legally marketed. Approval is the premarket review used for the highest-risk devices. If a simple tape says "FDA approved", read it as a reason to ask questions. Our eight questions to ask before buying a sleep gadget covers this in more detail.

Who checks the claims in ads?

The FTC checks health claims in ads. Its health products guidance says claims about health benefits must be backed by competent and reliable scientific evidence, and it describes randomized controlled trials as generally the kind experts would require. Marketers must also have at least the level of support they claim to have. A brand that says "clinically proven" needs research that actually tested its product for that benefit. We look at common examples in mouth tape marketing claims.

What does this mean when you're shopping?

Light regulation says nothing either way about whether a product works. The research is small but encouraging. A small 2022 study of mouth breathers with mild sleep apnea found snoring roughly halved after a week of taping, though there was no comparison group (the research). In a 2000 placebo-controlled trial in people with chronic rhinitis, nasal strips lowered snoring frequency.

What the system leaves to you is reading claims carefully. Look for a brand that describes its product's purpose plainly, names its materials and says who shouldn't use it. Our guide to choosing a sleep tape brand has a checklist, and what mouth tape is made of explains the materials. Before your first night, check your nasal airflow with the nose test, and read is mouth taping safe? if you have any health conditions.
