How Technology is Reinventing Oral Health
For too long, oral health has been treated as a maintenance problem; something you deal with twice a year in a dentist’s chair. That’s changing fast. From AI reading your X-rays to a toothbrush that talks back to personalized probiotic pastes grown from your own microbiome data, a wave of verifiable, investable technology is reshaping what it means to take care of your teeth, and your whole body.
The Stakes Are Higher Than a Clean Smile
Let’s start with why this matters beyond aesthetics. The link between oral health and systemic disease is no longer speculative, it’s published, replicated science.
A 2024 consensus report by the European Federation of Periodontology and WONCA Europe, published in the European Journal of General Practice, concluded that periodontitis is independently associated with cardiovascular disease, diabetes, chronic obstructive pulmonary disease, obstructive sleep apnoea, and COVID-19 complications. (https://pubmed.ncbi.nlm.nih.gov/38511739/) A cross-sectional analysis of 13,772 adults using NHANES data from 2017–2020, published in Scientific Reports in March 2025, found statistically significant associations between periodontitis and diabetes, and between dental caries and hypertension. (https://www.nature.com/articles/s41598-025-92523-6)
The numbers are stark: oral diseases affect nearly 3.5 billion people globally, with the economic burden estimated at $710 billion annually. (https://www.jdentacs.com/article_234302.html) And yet, the dominant paradigm of oral care; detect decay, drill it out, fill it in, has barely changed since the 20th century.
Technology is starting to disrupt that at every layer of the stack.
AI Diagnostics: The Second Opinion That Never Gets Tired
The most commercially mature technology in this space is AI-powered dental diagnostics, and it’s already FDA-cleared and in clinical use.
Overjet, a Boston-based startup, has received FDA clearance for its AI that reads dental radiographs, detecting caries, quantifying bone loss, and identifying pathological changes—all annotated directly on the X-ray for both clinician and patient clarity. The platform integrates with existing practice management systems and has been adopted by large dental service organizations (DSOs) as a tool for standardizing diagnoses across multi-site operations. (https://scanoai.com/blog/top-10-ai-dental-company)
VideaHealth raised the bar further in January 2025 with the launch of its Caries 3.0 model, described as the most sophisticated dental caries detection system to date, aimed at improving both accuracy and consistency of diagnoses across providers. The company reports that its AI has reduced diagnostic variation by 35% and increased detection of missed pathologies by 24% compared to unaided clinicians. (https://www.videa.ai/resources)
Pearl integrated its “Second Opinion” AI into Open Dental Software’s imaging module in February 2025, bringing AI-powered radiographic examination to practices nationwide without requiring new hardware. (https://www.knowledge-sourcing.com/report/ai-in-dental-imaging-market)
The market context is significant: the AI in dental imaging sector was valued at $1.28 billion in 2025 and is projected to reach $3 billion by 2030 at an 18.6% CAGR. (https://www.knowledge-sourcing.com/report/ai-in-dental-imaging-market) Meanwhile, around 57 million Americans live in dental health professional shortage areas, according to the CDC—a gap that AI diagnostics are positioned to help close.
At the IDS 2025 conference—the world’s largest dental trade fair—AI was not a sidebar but a throughline. 3Shape’s flagship TRIOS 6 intraoral scanner debuted with a hyperspectral imaging system capturing data via white light, fluorescence, and near-infrared, enabling five simultaneous AI diagnostic capabilities from a single standard scan: occlusal caries detection, tooth wear measurement, gingival recession tracking, plaque visualisation, and proximal caries assessment. (https://instituteofdigitaldentistry.com/news/ids-2025-highlights-the-latest-breakthroughs-in-digital-dentistry/) AI has moved from standalone software to a core feature baked into clinical hardware.
Smart Devices: Your Toothbrush Is Watching
Consumer-facing smart oral health devices are becoming genuinely capable rather than just expensive novelties.
Oclean launched its X Ultra WiFi Smart Sonic Toothbrush in July 2024, debuting at CES 2024 before commercial release. The X Ultra uses bone conduction technology to deliver real-time AI voice guidance while brushing—alerting users when they’re pressing too hard, moving too fast, or missing zones—without needing headphones or speakers. Its companion app, Oclean Care+, processes brushing data and returns personalised coaching based on long-term habit patterns. Priced at $129.99, it’s designed to be disruptive on price as well as features. (https://www.globenewswire.com/news-release/2024/07/17/2914624/0/en/Oclean-Announces-Availability-of-its-First-AI-Integrated-Electric-Toothbrush-The-X-Ultra.html)
Separately, researchers in early 2024 unveiled ToMoBrush, a prototype that turns a standard sonic toothbrush into a dental screening tool by fitting it with a microphone to capture acoustic resonance signals as bristles vibrate against teeth. Because cavities alter tooth structure, they change the resonance signature—allowing the device to flag early decay without X-rays or a clinic visit. (https://eu.oclean.com/blogs/tips/using-sonic-toothbrushes-for-early-dental-disease-detection-the-rise-of-smart-health-sensing) It’s a research prototype for now, but it illustrates where this category is heading: toward passive, continuous health monitoring integrated into tools people already use.
Oral-B and Philips Sonicare continue to evolve their incumbent smart brush lines—the Oral-B iO Series includes 3D brushing tracking and integration with Apple Health and Google Fit—though at significantly higher price points. The global toothbrush market, currently valued at around $9 billion, is projected to reach $16.27 billion by 2034, driven heavily by smart device adoption.

Microbiome Science: Rethinking What “Clean” Means
Perhaps the most intellectually interesting shift in oral health is the move away from the “kill everything” model of hygiene toward one of microbial balance. The human oral microbiome hosts over 700 species of bacteria. Many of them are beneficial. Traditional toothpastes—loaded with sodium lauryl sulfate, triclosan, and alcohol-based antibacterials—make no distinction between the harmful and the helpful.
A cohort of companies is building on microbiome science to challenge this.
Viome, a Bellevue-based diagnostics company with $175 million in total funding, launched its personalised MyBiotics Toothpaste and Gel in July 2024. The product line is built on insights from Viome’s Oral Health Intelligence test, which uses proprietary RNA sequencing to analyse each user’s individual oral microbiome. The personalised formula—delivered monthly for $79—includes prebiotics and postbiotics calibrated to the individual’s Oral Health Score, based on findings from 26 university research studies. (https://www.geekwire.com/2024/wellness-startup-viome-targets-oral-health-with-toothpaste-and-gel-formulated-via-microbiome-data/)
In the academic sphere, a clinical trial published in Microbiome Research Reports in January 2025 demonstrated that a live probiotic toothpaste containing Streptococcus salivarius M18 significantly increased beneficial bacterial colonisation in the oral cavity, with effects persisting after discontinuation. Over 80% of trial participants reported a clean feeling after use. (https://www.mdpi.com/2673-8007/5/1/14)
UK-based Luvbiotics, selected as a Probiota Pioneer at a 2026 industry event, formulates oral care products using Lactobacillus reuteri and Lactobacillus paracasei—strains with established efficacy against Streptococcus mutans (a primary driver of tooth decay) and Porphyromonas gingivalis (linked to periodontitis). The brand positions itself explicitly as working with the oral microbiome rather than against it. (https://www.nutraingredients.com/Article/2026/01/12/probiotic-brand-challenges-typical-toothpastes/)
The oral probiotic market was valued at $3.09 billion in 2024 and is projected to reach $7.07 billion by 2035, growing at 7.82% CAGR. (https://introspectivemarketresearch.com/reports/oral-dental-probiotics-market/) The category is expanding rapidly beyond supplements into toothpastes, mouthwashes, lozenges, and chewable tablets.
One note of caution: some dental professionals remain sceptical of the clinical evidence base for microbiome-targeted products. As periodontist Dr. Reena Wadia noted in Business of Fashion in April 2025, influencing the oral microbiome remains scientifically difficult, and the research needs to catch up with the marketing. (https://www.businessoffashion.com/articles/beauty/the-next-wellness-frontier-oral-microbiome-products/) The underlying science is sound; the product-level claims are not always fully validated.
The Strategic Opportunity: Oral Health Is Whole-Body Health
The convergence of AI diagnostics, smart devices, and microbiome science is creating something bigger than improved dental care: it’s creating an integrated oral-systemic wellness category.
This is where the opportunity is genuinely strategic for companies in the broader health, beauty, and wellness sectors. The oral-systemic connection—that what happens in the mouth influences heart disease risk, glycaemic control, respiratory outcomes, and potentially Alzheimer’s—gives oral health technologies a claim on healthcare spending that toothpaste never had.
The AI dental market alone is forecast to grow from $421 million in 2024 to over $3.1 billion by 2034. (https://www.insightaceanalytic.com/report/ai-in-dentistry-market/3004) The innovations driving that growth—cloud-based AI diagnostics, real-time home monitoring, personalised formulations—are not incremental improvements to the old model. They represent a genuine shift from episodic, repair-focused dentistry to continuous, prevention-first wellness.
Companies that move now—forming partnerships with AI diagnostics firms, investing in microbiome R&D, integrating oral data with skin and metabolic health platforms—will be positioned to lead a market that is still being defined. Those that wait will be playing catch-up with startups that are already shipping product, publishing clinical data, and building consumer trust.
The technology is real. The science is strengthening. The market is moving. The question is who gets there first.
