Feno is an oral-care brand focused on making daily brushing simpler and more consistent. Its offerings may help reduce common brushing issues such as missed spots, uneven pressure, or rushed technique.
The brand’s product line revolves around the Smartbrush, its accessories, and an app that tracks brushing habits and highlights areas that may need more attention. It aims to support you if you want a faster routine or find it difficult to stay consistent with manual brushing.
In this review, we’ll take a closer look at Feno’s product lineup, the potential advantages and limitations of its approach, and what current users say about their experience to help you understand whether the brand is the right fit for your needs.
As per the official website, Feno offers smart devices, personalized cleaning tools, and microbiome-based insights to support a more informed daily hygiene routine. It focuses on making oral care more measurable by pairing hardware with app-driven analysis rather than relying solely on traditional brushing methods.
Its core product, the Feno Smartbrush, uses a Wi-Fi and Bluetooth–enabled smart handle, an HD oral scanner, and the Feno Plus app to track brushing patterns and provide personalized reports.
Feno also offers a range of supporting products, including TrueFit Mouthpiece™, which is available in six sizes, and uses a flexible plate and 18,000 soft bristles to provide full-mouth coverage in a short brushing cycle.
The brand’s Feno Foam Toothpaste and Foam Refill use a micro-foam formula to reach tighter spaces, support enamel health, and maintain freshness.
To make its system more accessible, it also provides comprehensive bundles such as the Founder’s Edition Bundle, Founders Edition Plus, Elite Oral Health, and a Starter Kit. These may include combinations of the Smartbrush, Snap Charger, TrueFit Mouthpiece, Feno Foam, and a tongue scraper, with some bundles adding a year of analytics or coaching through the Feno Plus platform.
The Salivary Microbiome Test Kit may help you understand the balance of microorganisms living in your mouth. Periodontal disease begins when bacterial biofilms attach to tooth surfaces and release enzymes and inflammatory byproducts that weaken tissue and bone.
As these biofilms mature, they can create pockets that shelter additional pathogens. As oral microbes can enter the bloodstream, shifts in the salivary microbiome have been linked to broader issues such as metabolic changes, cardiovascular strain, and chronic inflammation.
The makers state that this Microbiome Test Kit analyzes the relative abundance of key microbes in your saliva, highlighting those associated with gum inflammation, tissue breakdown, or protective activity. This helps you understand which biological pathways may be shaping your current oral health and guides more targeted next steps.
The kit pairs with the Smarthandle, a scanning device that captures high-definition images of your teeth and gums. Wireless connectivity allows your oral health metrics to be stored and monitored through the Feno Plus app, with a travel-friendly battery and magnetic charging system built in for routine use.
The system also combines Feno Foam, which may help neutralize odor-causing volatile sulfur compounds, supporting longer-lasting freshness. This kit may reduce routine disruption of harmful biofilms through mechanical and ingredient-based mechanisms.
As per the official website, the TrueFit Mouthpiece provides full-mouth coverage using 18,000 ultra-soft nylon bristles arranged on a flexible plate. This plate adapts to your dental arch, allowing the bristles to contact multiple tooth surfaces at once. Nylon bristles are engineered to bend under low force, which helps reduce abrasive wear on enamel while still providing enough mechanical action to disrupt plaque.
You can choose from six mouthpiece sizes, each shaped to align more accurately with individual arch dimensions. A closer anatomical fit supports more uniform bristle contact along the gumline, where microbial accumulation tends to be highest.
The accompanying FitKit app uses AI measurements of your jawline and dental arch to guide size selection, helping ensure that the mouthpiece reaches tight or curved areas where manual brushes often miss. As biofilm tends to reestablish itself within hours, the makers suggest replacing the mouthpiece every three months to help maintain bristle integrity and cleaning efficiency.
The TrueFit Mouthpiece supports routine removal of plaque before it matures into more resilient layers that are harder to remove by reaching hard-to-access zones and applying consistent motion.
The Founders Edition Plus package combines hardware, consumables, and digital tools to support a more measurable approach to oral hygiene. It includes the Feno Smartbrush with its wireless charger, a personalized TrueFit Mouthpiece, three tubes of Feno Foam, a tongue scraper, and a 12-month subscription to the Feno Plus platform. These component contributes differently to cleaning, monitoring, and interpreting oral health patterns over time.
The Smartbrush functions as a scanning and brushing device. Its high-density soft nylon bristles are engineered to flex under pressure, helping the brush reach irregular tooth contours while minimizing excess abrasion on enamel.
During use, the system delivers 250 strokes per cycle and operates on a 20-second full-mouth timer when paired with the TrueFit Mouthpiece. The mouthpiece’s bristle array cleans all tooth surfaces simultaneously, reducing the role of individual brushing techniques
The Feno Plus platform extends the system beyond brushing by collecting imaging and usage data from the Smartbrush. These visuals may show early changes such as redness along the gumline, tartar accumulation, or dark spots associated with demineralization.
As per the official website, the additional components, such as the tongue scraper, contribute to daily hygiene by removing debris and volatile sulfur compound–producing bacteria from the tongue surface. Tongue coatings can act as a reservoir for odor-causing microbes, so mechanical removal helps reduce their population.
The included Feno Foam provides foaming action that could reach narrow spaces, and its formulation supports routine plaque disruption when used alongside the Smartbrush.
Feno Foam Toothpaste is formulated to expand into a fine, micro-foam that moves into narrow spaces between teeth and along the gumline. Its structure allows the foam to remain in contact with surfaces where plaque biofilm tends to accumulate.
Biofilms form when oral bacteria produce sticky polysaccharides that help them adhere to enamel and protect themselves from mechanical disruption.
The foaming texture of the paste increases surface coverage, helping the formulation reach areas that may coat less evenly, especially when paired with the TrueFit Mouthpiece.
The toothpaste contains xylitol that certain oral bacteria cannot effectively metabolize. Species such as Streptococcus mutans attempt to take up xylitol through their carbohydrate transport systems, but they cannot convert it into usable energy. This process disrupts their internal metabolic cycle, reducing their acid production and limiting their ability to bind to enamel.
Natural wild mint extract in this formula may help neutralize volatile sulfur molecules produced by bacteria on the teeth and tongue. It could help disperse odor-causing sulfur gases and provide a cleaner mouthfeel after brushing. Mint also contains mild phytochemicals that may support a refreshing sensation without relying on harsher synthetic additives.
The Founder’s Edition Bundle combines Feno’s full set of oral care tools, offering both mechanical cleaning and digital tracking features. The bundle includes the Feno Smartbrush, which consists of the Smarthandle and Snap Charger, a TrueFit Mouthpiece, three bottles of Feno Foam foaming toothpaste, and a tongue scraper. The makers state that the Founder’s Edition Bundle could help address plaque formation, biofilm buildup, and changes in oral tissue over time.
As per the official website, the Smartbrush functions as both a cleaning and imaging device. Its embedded scanner captures high-definition views of tooth surfaces and gumlines, allowing the system to detect early changes such as plaque accumulation, redness associated with inflammation, or areas where brushing patterns may be inconsistent.
The TrueFit Mouthpiece provides full-arch cleaning using a bristle plate designed to conform to your dental arch. Consistent bristle contact helps mechanically disrupt plaque biofilm, which is a structured layer of bacteria protected by a polysaccharide matrix. Breaking this matrix is an essential step in reducing the bacterial load that contributes to inflammation, decay, and gum irritation.
The bundle also includes three bottles of Feno Foam, which may support distribution into tighter spaces where plaque tends to accumulate. On the other hand, the tongue scraper is provided as an additional tool for daily hygiene.
As per the official website, the Elite Oral Health system combines daily cleaning, imaging, and biomarker tracking to give you a more detailed view of your oral environment. Instead of relying solely on manual technique, the system uses a personalized mouthpiece that provides a uniform 20-second full-mouth clean.
Daily scans captured by the Smartbrush document changes in gum color, surface texture, and visible plaque accumulation. The system’s disease-risk detection feature analyzes visible oral changes that may correlate with broader health concerns. Conditions like cardiovascular disease, diabetes, and chronic inflammation often show early oral indicators, including increased gum bleeding, slower healing, or shifts in microbial balance. While these signs are not diagnostic on their own, they can serve as prompts for follow-up care or additional evaluation.
Subscription access to the Feno Plus platform connects your scan data with real-time professional guidance. Dental experts can interpret changes in your images and brushing patterns, offering context for observations such as recurring plaque hotspots or signs of localized irritation. This reduces the delay between noticing an issue and receiving informed feedback.
The system also includes a salivary microbiome test that examines bacterial composition and biomarkers linked to gum health. Variations in microbial communities can reflect changes in acidity, immune response, or biofilm activity.
Feno claims that their Smartbrush contains an oral scanner and camera setup that gathers detailed images of the teeth and gums. These images reportedly sync to the Feno Plus app, where AI models and licensed dentists claim to provide insights, reports, and personalized recommendations based on the scans. This setup allows the brand to claim that daily brushing becomes part of a monitored, tech-supported wellness routine.
The brand also claims that its U-shaped Smartbrush uses a high number of bristles, more than a standard toothbrush, which may allow it to clean multiple tooth surfaces and the gumline at the same time. This feature is presented as part of the connected system that blends mechanical cleaning with ongoing digital evaluation.
Feno claims to follow a data-driven approach by treating everyday oral care as an activity that can be measured, tracked, and adjusted through digital tools. The company states that its app compiles brushing information over time, produces oral wellness reports, and highlights trends in user habits. It also highlights that the app updates guidance based on changes in brushing behavior, gum condition, or other signs detected through the Smartbrush.
The brand links its approach to scientific findings showing that oral health indicators, such as inflammation and plaque buildup, may relate to broader systemic concerns, including cardiovascular risks.
Feno positions its monitoring tools as a way to observe oral markers more regularly, rather than relying solely on occasional dental visits by referencing these connections. This perspective supports the idea that continuous data collection can play a role in maintaining oral wellness.
Several products contribute to this system, including the TrueFit Mouthpiece, the Salivary Microbiome Test Kit, and the Feno Foam Toothpaste. The Smartbrush gathers usage data, while the mouthpiece and microbiome kit are presented as tools for measuring additional oral indicators. The app uses information from these sources to generate feedback and AI-based suggestions that may help you adjust your daily routines and address specific risk factors.
Feno has a newly launched brand identity because it entered the oral care market only recently with the release of its Smartbrush technology in mid-2024, developed through Share Ventures. As a young company emerging from a venture studio, it does not yet have the established reputation, long-term testing history, or consumer familiarity that more traditional oral-care brands have built over many years.
The early stage of the brand means that long-term user feedback and performance data are limited. While initial reviews and industry attention have helped introduce the brand, there is not yet sustained evidence showing how its products perform with extended use or how well customers remain engaged over time. Early offerings such as the TrueFit Mouthpiece, Founders Edition Plus, and Feno Foam Toothpaste are still too new to demonstrate multi-year reliability or consistent repeat-purchase patterns.
As the brand depends mainly on direct-to-consumer sales through its website and online marketing, exposure remains narrow without support from major retailers, dental professionals, or clinical channels.
Quip and Feno both focus on improving oral health, but their approaches differ substantially in design, technology, and user experience.
As per its official website, Quip offers a familiar brushing framework supported by products such as the Sonic Toothbrush, Ultra™ Next Generation Smart Sonic Electric Toothbrush, Rev Oscillating Toothbrush, Rechargeable Cordless Water Flosser, Daily Strengthening Anticavity Toothpaste, and Rapid or Ritual Dissolvable Whitening Strips. These tools support traditional brushing habits through timed vibrations, gentle sonic motions, pressure sensors, and app-based habit tracking. The brand’s emphasis remains on consistency and proper technique rather than changing how brushing is performed.
Feno, on the other hand, introduces a more technology-driven and automated oral-care system. Its lineup includes the Feno Smartbrush, Feno Smarthandle, TrueFit Mouthpiece, Feno Foam, Tongue Scraper, and advanced tools like the Salivary Microbiome Test Kit.
Bundled offerings such as the Founder’s Edition Bundle, Founders Edition Plus, and Elite Oral Health combine these components into a suitable routine. The Smartbrush combines Wi-Fi, Bluetooth, and a high-definition intraoral scanner that works with the Feno Plus app to deliver personalized oral-health insights based on proprietary AI analysis.
The device designs further illustrate their different priorities. Quip maintains a traditional long-handle format across its Sonic, Ultra, and Rev models, requiring standard brushing motions supported by guided cues.
Feno uses a U-shaped TrueFit Mouthpiece equipped with 18,000 ultra-soft nylon bristles sized through the AI-driven Feno FitKit, enabling full-mouth cleaning in about 20 seconds. This approach aims to reduce technique variability by providing near-complete coverage automatically.
Their use of technology also sets them apart. Quip’s smart features focus on strengthening daily habits through reminders, tracking, and brush-head replacement notifications. Feno’s system is more diagnostic. Its Smarthandle captures dental imaging, offers a 7-day battery life, supports wireless charging via the Snap Charger, and provides detailed oral-health reports through AI and professional review. This positions Feno as an option that extends into monitoring and preventive insights, not just brushing.
Quip provides a streamlined, accessible way to improve brushing habits, while Feno offers a more advanced, system-level approach that combines automation, diagnostics, and preventive insights.
Mode emphasizes simplicity, design, and everyday usability through the Mode Electric Toothbrush, priced around $99-$148. It also features a completely wireless charging dock that frees counter space, and the built-in nightlight adds convenience without introducing complexity. The brand’s overall product range remains intentionally limited to essentials such as the toothbrush, the Mode Brush Head 3-Pack (starting at $30), and the Mode Charging Case (regularly $40, discounted to $30). Even the subscription model is straightforward, offering a three-pack of brush heads at intervals the user selects, with the ability to pause or cancel at any time.
Feno takes a more expansive and technology-driven approach by offering a full ecosystem that extends beyond brushing. Its lineup includes the Feno Smartbrush, TrueFit Mouthpiece, Feno Foam Toothpaste, the Feno FitKit, and options like the Salivary Microbiome Test Kit. These components are also available in bundled formats, including the Founder’s Edition Bundle, Founders Edition Plus, and Elite Oral Health.
The Feno Smarthandle integrates Wi-Fi and Bluetooth connectivity, a high-definition oral scanner, and AI-supported assessments reviewed by dental professionals. The system works with the Feno Plus app to provide personalized insights into brushing patterns and overall oral health.
The brand also features TrueFit Mouthpiece, available in six sizes, which is designed for full-mouth coverage, completing a clean in roughly 20 seconds using 18,000 soft bristles and 250 strokes per cycle.
While both brands aim to enhance the user’s oral care routine, Mode offers a streamlined, design-focused option for an easy brushing experience. Feno focuses more on an integrated and data-informed system that combines hardware, app connectivity, personalized analytics, and diagnostic tools. Mode focuses on ease of use and aesthetic clarity, whereas Feno delivers a broader, more technologically advanced approach to oral health.

Most customers describe the Smartbrush as efficient, comfortable to use, and noticeably quicker than traditional brushing methods. Many users highlight the device’s ability to deliver a thorough clean in under 30 seconds, along with improvements in how their teeth and gums feel.
Many users describe the support team as responsive and helpful, especially when addressing early technical concerns such as motor, charging, or usability issues. The brand’s willingness to provide replacements and follow up appears to contribute positively to customer confidence, even when initial defects occurred.
However, a few users highlighted durability concerns, app functionality gaps, and the need for additional accessories. Some customers even mention delays or communication difficulties. These insights suggest that while the core product and service experience receives strong feedback, there is room for improvement as the brand evolves.
Our evaluation indicates that Feno presents a modern approach to oral care, supported by largely dependable customer service, while continuing to refine its technology and user experience.
Feno positions itself around advanced oral-health technology, centered on the Feno Smartbrush. The brand highlights that this device uses 18,000 bristles, a built-in oral scanner, and a personalized TrueFit mouthpiece to clean the entire mouth in 20 seconds. Feno also integrates app-based insights, AI-supported health monitoring, and optional salivary microbiome testing.
To understand how customers currently perceive the brand, we reviewed its Trustpilot rating, where Feno holds a 4.6 score based on more than 40+ reviews. This indicates a strong level of satisfaction among early users. However, the brand does not currently have a profile on the Better Business Bureau, which limits access to third-party oversight commonly used to track complaint patterns.
Feno shows promising early trust signals based on customer feedback, but the lack of BBB records means it is helpful to keep watching how the brand is examined by independent sources over time.
Feno focuses on bringing more measurable insight to everyday oral care through smart tools, app-based analysis, and microbiome indicators. The system observes your brushing habits, identifies changes over time, and offers feedback based on brushing analytics, AI-supported assessments, and salivary trends.
However, the brand is still early in its development, and long-term performance data, clinical validation, and broad user feedback remain limited. The experience depends heavily on the accuracy of software interpretation, and the brand’s reach is still narrow, which makes independent evaluation less available.
Before considering Feno, make sure you consider its insights as supportive, not diagnostic. It is essential to continue routine dental care and interpret microbiome results cautiously. You should also monitor for gum sensitivity when adjusting to new brushing patterns, avoid relying on the app for medical decisions, and review any unusual changes with a professional rather than assuming they reflect true oral trends.
