The Intraoral Wearable Market: Who's Building in This Space Right Now

Intraoral wearables aren't one product category anymore. Over the past few years, they've split into at least four distinct jobs, general wellness, sports safety, hands-free input, and sleep or health monitoring, represented by products from eight companies (seven if you count Prevent Biometrics and OPRO, which build one shared product line together, as a single entry).

A category represented by several companies, technologies, and use cases is more than a single-company positioning exercise. It's evidence of an emerging market.

This piece expands on the market overview covered in ClenchAlert's guide to intraoral wearable technology. If you're new to the category, that's the place to start for the fuller definition.

The Four Jobs Intraoral Wearables Are Being Built to Do

Every product covered in this roundup fits into one of four categories, organized by what it's actually built to notice, not by who makes it:

• General wellness / awareness: helping someone notice a pattern about their own body
• Sports safety / impact monitoring: tracking force and motion during athletic play
• Input control: using the mouth as a hands-free interface
• Sleep / health monitoring: tracking a biometric signal overnight.

General Wellness and Awareness

ClenchAlert sits in this category: a cheek-worn intraoral pressure sensor built to help someone notice sustained daytime jaw pressure, not diagnose or treat it. It's covered in more detail later in this piece, the rest of this roundup focuses on the other companies building in this space, since the goal here is showing the category exists independently of any one company's framing of it.

Sports Safety and Impact Monitoring

This is the largest and most established cluster in the category, largely because it grew out of a clear, funded need: measuring what happens to an athlete's head during play.

ORB Sport makes a custom-fit smart mouthguard for combat and contact-sport athletes. According to the company's own product materials, it pairs heart-rate monitoring with movement tracking and head-impact data, including impact region and force. ORB Sport states plainly that the device "is not designed or intended for use in the diagnosis, cure, mitigation, treatment, or prevention of any disease or condition."

HITIQ's PROTEQT is an instrumented mouthguard that measures head-impact events and summarizes severity through the company's own scoring system. HITIQ markets PROTEQT as part of a broader "concussion management" suite that includes a telehealth service a more clinically framed positioning than some other products in this cluster. No FDA clearance was identified in the company materials reviewed for this article, and readers evaluating PROTEQT's claims should look at HITIQ's own site directly rather than rely on this summary alone.

Prevent Biometrics develops instrumented mouthguard sensor technology and, since 2023, has partnered with mouthguard manufacturer OPRO to bring that technology to market in OPRO-manufactured mouthguards. Prevent Biometrics' own public materials describe its head-impact-monitoring technology as FDA 510(k)-cleared.

That's a meaningfully different regulatory step than the general-wellness devices covered elsewhere in this roundup, a 510(k) clearance means the FDA reviewed the device for a specific, defined use.

This article has not independently verified the exact cleared device name, 510(k) number, or whether every current OPRO-branded configuration matches the cleared one; readers who need that level of detail should consult the FDA's public 510(k) database directly.

SISU Sense, made by Akervall Technologies, is a custom-moldable mouthguard with an embedded three-axis accelerometer that reports head impacts to a companion app. The company states directly on its product page: "The SISU Sense is not a medical or diagnostic device... The SISU Sense Hit Sense technology does not diagnose concussion."

Input Control

Augmental's MouthPad takes the category in a different direction. Custom-fabricated from a dental scan and worn over the upper teeth like a slim retainer, it's a Bluetooth device that lets someone control a phone, tablet, or computer using tongue, head, and sip gestures. It isn't a wellness product, Augmental's own materials state the MouthPad "is not intended for diagnosing, treating, curing, or preventing any disease or medical condition."

As of its 2026 public launch, Augmental reports the device is used by more than 100 people, some for up to 16 hours a day. That's evidence that at least some users will adopt a custom-fit intraoral interface for extended use when it provides enough functional value, not proof that every intraoral device is equally comfortable or tolerable across other designs or populations.

Sleep and Health Monitoring

ProSomnus's HWO2 is one of the more recent entrants in this category, and the one furthest from the sports-safety cluster in both design and purpose. It's an intraoral oximeter, custom-fabricated from a 3D scan and worn against the buccal mucosa, the inside of the cheek, overnight, tracking blood oxygen saturation and pulse rate through optical sensing, the same underlying principle as a fingertip pulse oximeter.

ProSomnus reports that HWO2 is listed with the FDA as a buccal mucosal wellness oximeter. FDA establishment registration and device listing are not the same as FDA clearance, approval, or authorization, and do not by themselves indicate that the FDA reviewed the product's performance claims.

The sensing approach behind HWO2 has also been studied independently. A peer-reviewed accuracy study (Snow et al., "A Buccal Mucosal Oximeter Accurately Measures Arterial Oxyhemoglobin Saturation," 2025) conducted at the University of Calgary's Cumming School of Medicine tested the device against gold-standard CO-oximetry and ECG readings across a range of oxygen levels, from normal down to severe hypoxia, in awake volunteers under controlled laboratory conditions.

Across 325 matched blood-oxygen readings, the device measured within an accuracy root-mean-square error of 2.94%; across 346 matched pulse-rate readings, within 2.08%. That study provides controlled-condition accuracy evidence for this specific measurement task, it doesn't, by itself, establish performance across all overnight users, clinical conditions, or home environments.

It's still a useful reference point for this roundup: it shows part of the intraoral sensing category is being independently tested and published, not just described in marketing copy.

Market Landscape at a Glance

Where ClenchAlert Fits

Among all of this, ClenchAlert occupies a specific, narrow lane: a general-wellness, daytime-only device built around one signal, sustained pressure associated with daytime tooth contact, rather than motion, position, or a sleep-time biometric.

It doesn't require a dental scan or bite registration; it's designed for user placement according to the instructions provided. When it detects sustained jaw pressure, it delivers a gentle vibration cue:

Notice. Release. Reset.

That's the full extent of what it claims to do, covered in more detail in the pillar guide and in ClenchAlert's guide to how intraoral wearable sensors work.

Why This Category Is Fragmenting Into Different Jobs

The pattern across this roundup is specialization, not convergence. As intraoral wearables have moved from an idea to real products, they haven't collapsed into one generic "smart mouthguard", they've split along the lines of what problem each one is solving.

Sports-safety devices need fast motion and impact data for people managing athlete risk in real time. An input-control device needs precise position sensing and little else. A sleep-health device needs a stable, accurate biometric reading across hours of stillness. A wellness-awareness device needs to reliably tell a sustained behavior apart from ordinary background noise.

Those are different engineering problems, and, as this roundup shows, increasingly different regulatory postures, the same broad category now spans general-wellness products, a manufacturer-listed wellness oximeter, and at least one line of products built on FDA-cleared impact-monitoring technology. That range is strong evidence that "intraoral wearable technology" describes an active, emerging category, rather than a term created for one product.

What ClenchAlert Is Not

ClenchAlert is not a mouthguard, night guard, bite guard, or dental appliance, and it is not a substitute for one. It is not intended to diagnose, treat, cure, mitigate, or prevent bruxism, TMJ disorders, headaches, tooth damage, sleep disorders, or any medical or dental condition. It is designed for awake, daytime use only.

ClenchAlert does not replace a dentist, physician, or sleep specialist. If a dentist has noticed tooth wear, or if jaw pain, headaches, or sleep concerns persist, those are conversations to have with a qualified professional.

Frequently Asked Questions

What companies make intraoral wearable technology? Several, building for different purposes. ORB Sport, HITIQ, and the Prevent Biometrics/OPRO partnership build for sports-safety impact monitoring. Augmental builds for hands-free device control. ProSomnus builds for sleep and health monitoring. ClenchAlert builds for daytime jaw-pressure awareness.

Is a smart mouthguard the same as an intraoral wearable? Not exactly. A smart mouthguard is one type of intraoral wearable, usually built for sports-safety impact monitoring. The broader category also includes devices that aren't mouthguards at all, like retainer-style oximeters and bitewing-style pressure sensors.

Are any intraoral wearables FDA-cleared? Some report holding FDA clearance for specific uses. Prevent Biometrics, whose technology is used in OPRO's instrumented mouthguards, describes its head-impact-monitoring technology as FDA 510(k)-cleared.

Other products in this category, including ClenchAlert, are marketed for general wellness and self-awareness rather than diagnosis or treatment. Products with appropriately limited wellness intended uses may not require 510(k) clearance, but regulatory status depends on each product's specific claims, functions, and intended use, it isn't something a company can establish just by calling a product a "wellness" device.

What's the difference between a wellness wearable and a medical device? A general-wellness wearable is built to help someone notice a pattern about their own body, without diagnosing or treating anything. A medical device with FDA clearance has gone through a specific regulatory review tied to a defined use, such as head-impact monitoring. Both exist within the broader intraoral wearable category, and it's worth understanding which kind of product you're looking at.

Start With Awareness

The intraoral wearable market is bigger, and more varied, than any single product page can show. Sports-safety mouthguards, input-control devices, sleep oximeters, and daytime wellness sensors are all part of the same emerging category, each built to notice something different. ClenchAlert's part in it is narrow and specific: helping you notice sustained daytime jaw pressure, with a gentle vibration cue and nothing more claimed.

Explore ClenchAlert and see how a gentle jaw-pressure cue can become part of a daytime awareness practice.

For daytime awareness practice only. Not a medical or dental treatment.

ClenchAlert^® is intended for general wellness, self-awareness, and educational support only. It is not intended to diagnose, treat, cure, mitigate, or prevent bruxism, TMJ disorders, headaches, tooth damage, sleep disorders, or any medical or dental condition.
