Executive Summary#
Technology and ingredient innovation are changing China's oral care market, creating premium segments in which consumers are willing to pay more for performance they can see. Sweep-vibration electric toothbrush technology was the fastest-growing functional concept in 2024. Hydroxyapatite toothpaste grew 155.6% YoY to CN¥ 460 million, in a segment that is highly concentrated and sold at premium prices. We believe these two waves of innovation show the market moving away from competition on commodity products towards competition on differentiated products that carry more value.
Where Functional Innovation Is Happening#
China's oral care market is developing along two axes at once, expanding into new functional claims while existing claims are deepened through technology upgrades. Moojing Market Intelligence's concept analysis shows that sweep-vibration has the highest social media word frequency of any functional concept (163.0), and that this attention comes with strong commercial traction.
Established functional concepts such as antibacterial (CN¥ 5.40 billion) and breath freshening (CN¥ 8.09 billion) keep large absolute sales but grow more slowly, which is characteristic of mature positions in a market. The strongest growth comes from newer concepts, and three-sided toothbrush designs, smart technology and fully automatic operation are early-stage opportunities with considerable room to grow.
Functional concepts in oral care: social word frequency and sales, 2023 and 2024#
| Concept | Word Frequency | 2023 Sales (CN¥M) | 2024 Sales (CN¥M) |
|---|---|---|---|
| Breath | 24.5 | 7895.0 | 8093.8 |
| Antibacterial | 56.8 | 5238.0 | 5400.3 |
| Cavities | 10.0 | 3533.0 | 4345.4 |
| Wide Head | 47.0 | 1534.0 | 2065.9 |
| Stain Removal | 36.2 | 2152.0 | 1665.1 |
| Brightening | 25.4 | 1865.0 | 1611.8 |
| Three-Sided | 60.9 | 1038.0 | 1573.2 |
| Smart | 13.6 | 1803.0 | 1433.7 |
| Sweep-Vibration | 163.0 | 468.0 | 1422.3 |

| Anti-Sensitivity | 81.2 | 1477.0 | 502.2 |
| Fully Automatic | 141.8 | 1365.0 | 463.4 |
| Battery Life | 54.6 | 1013.0 | 455.8 |
| Enamel | 53.3 | 823.0 | 434.0 |
| Orthodontic | 39.5 | 524.0 | 383.3 |
| Medical-Grade | 12.5 | 471.0 | 360.4 |
| Plaque | 37.1 | 757.0 | 218.6 |
| Tongue Coating | 67.3 | 126.0 | 31.0 |
| Tartar | 11.4 | 4000.0 | 2119.9 |
| Enamel (alt) | 17.6 | 293.0 | 252.1 |
The distribution points to three kinds of opportunity for brands entering the market: technology differentiation (sweep-vibration and AI), specialised health claims (medical-grade and orthodontic) and sensory enhancement (long-lasting fragrance and enamel care). We believe brands positioned where emerging technology meets a proven consumer need have the strongest growth potential.
Sweep-Vibration Changes the Electric Toothbrush Market#
The electric toothbrush market reached CN¥ 7.57 billion in 2024, growing 4.8% YoY, but the headline figure hides a large structural change. Unit volumes fell 11.7% while average selling prices rose 18.6% to CN¥ 149.6, which confirms that consumers are trading up to more advanced cleaning technologies.
Sweep-vibration technology is at the centre of this shift. It combines sweeping and vibrating motions for more thorough cleaning, and its sales grew faster than those of any other functional concept in 2024.
The technologies in the category are maturing in a clear order. Sonic technology remains the baseline, and its sales fell 19.5% YoY as it became standard and could no longer command a premium price. Multi-mode and bone conduction each grew 240.0%, micro-bubble 188.4% and AI integration 87.1%, while display screen features grew 174.9%, which indicates growing demand for smart, connected oral care devices.
This pattern of "basic function standardization combined with high-end function diversification" means that brands need to keep sonic as a baseline while investing in one or more differentiating technologies if they want to compete at higher price points.
Hydroxyapatite: The Ingredient Changing Toothpaste#
Ingredient innovation in toothpaste follows the same pattern as technology innovation in electric toothbrushes. Hydroxyapatite, a calcium phosphate compound and a major component of teeth and bones, has become the fastest-moving ingredient concept in oral care, and toothpaste containing it reached CN¥ 460 million in sales in 2024, up 155.6% YoY.
Hydroxyapatite accelerates penetration while fluoride ingredient growth slows#
| Ingredient | Word Frequency | 2023 Sales (CN¥M) | 2024 Sales (CN¥M) |
|---|---|---|---|
| Fluoride | 33.6 | 2578.1 | 3365.2 |
| Mint | 34.9 | 1351.1 | 2050.0 |
| Hydroxyapatite | 144.9 | 325.0 | 540.3 |
| Amino Acid | 106.6 | 521.0 | 389.2 |
| White Tea | 96.3 | 540.0 | 301.7 |
| Jasmine | 91.0 | 357.0 | 223.5 |
| Herbal | 67.7 | 352.0 | 209.1 |
| Niacinamide | 90.8 | 754.0 | 208.8 |
| Rose | 67.0 | 339.0 | 110.7 |
| Lime | 42.5 | 174.0 | 86.5 |
| Longjing | 50.0 | 125.0 | 66.8 |
| Lysozyme | 61.5 | 121.0 | 37.0 |
| Calcium | 76.6 | 79.0 | 32.2 |
| Sodium Hyaluronate | 20.2 | 57.0 | 29.4 |
The data divides the ingredients into two clear groups. Fluoride is still the largest ingredient by sales, at CN¥ 3.37 billion, but it sits in the low-penetration zone of social discussion, which suggests that consumers take it for granted and do not go looking for it. Hydroxyapatite has the highest word frequency (144.9) of any ingredient, alongside CN¥ 540.3 million in sales, which shows that consumers are actively searching for and buying this emerging ingredient.
The hydroxyapatite toothpaste segment is highly concentrated and sold at premium prices, and no established second brand has yet emerged, which leaves an opening for brands with clinical credibility and the ability to tell an ingredient story.
The prominence of niacinamide, a skincare ingredient that had moved into oral care by 2024, points to a wider convergence between the two categories. As consumers learn about ingredients through their skincare routines, they apply the same way of judging products to oral care, which creates opportunities to use familiar active ingredients in a new context.
Strategic Implications for Market Entrants#
The two waves of innovation, in technology and in ingredients, have different implications for strategy. For electric toothbrush brands, the data suggests investing in sweep-vibration or AI-enabled features to avoid commoditisation in the shrinking sonic segment, and Laifen is one of the brands that has built its electric toothbrush range around sweep-vibration technology. For toothpaste brands, hydroxyapatite is a proven premium positioning that rewards investment in R&D and clinical evidence more than competition on price.
Across both categories, technology differentiation through sweep-vibration, AI and bone conduction commands significant price premiums, and ingredients marketed on clinical evidence, such as hydroxyapatite and lysozyme, appeal to health-conscious consumers who are willing to pay more. Ingredients carried over from skincare, such as niacinamide and sodium hyaluronate, open further positioning opportunities in oral care.
In a market where basic functions have become standard, we believe innovation in brushing technology or in ingredient formulation is what decides which brands win the premium segments.

Frequently Asked Questions
A shift from commodity competition to differentiation, running on two axes at once: brushing technology and formulation ingredients. Sweep-vibration technology, which combines sweeping and vibrating motions, was the fastest-growing functional concept in 2024, and as a product concept it carries the highest social word frequency, at 163.0. On the ingredient side, hydroxyapatite toothpaste grew 155.6% to CN¥ 460 million. Established concepts such as breath freshening at CN¥ 8.09 billion and antibacterial at CN¥ 5.40 billion still hold the scale, but they grow slowly, which is the signature of a mature position.
Because buyers are trading up. The category reached CN¥ 7.57 billion in 2024 at +4.8%, but unit volumes fell 11.7% while average selling prices rose 18.6% to CN¥ 149.6, so fewer brushes sold and each was worth substantially more. The technology hierarchy explains it: sonic remains the baseline but contracted 19.5% as it standardised and stopped commanding a premium, while multi-mode and bone conduction each grew 240.0%, micro-bubble 188.4%, display screen features 174.9% and AI integration 87.1%. By 2024 sonic had become table stakes, and a brand needs at least one differentiating technology on top of it to compete above the entry price.
Because consumers are actively seeking it rather than merely accepting it. Hydroxyapatite is a calcium phosphate compound and a major component of teeth and bone, and it carries the highest word frequency of any oral care ingredient at 144.9 alongside CN¥ 540.3 million in sales. Fluoride is the instructive contrast: still the dominant ingredient at CN¥ 3.37 billion, but sitting in the low-penetration discussion zone, taken for granted rather than searched for. The segment is also highly concentrated, and no established second brand has emerged, which leaves an opening for a brand with clinical evidence and an ingredient story to tell.
Skincare ingredients are migrating into oral care, and niacinamide and sodium hyaluronate appeared in toothpaste formulations in 2024. What matters most is the evaluative habit these ingredients bring with them. Consumers who became ingredient-literate through skincare routines apply the same framework to oral care: they read the active, look for a mechanism, and expect a claim they can check. That converts a category historically sold on brand and flavour into one sold on formulation, and it is the same underlying shift that makes hydroxyapatite work. For a brand it means ingredient storytelling capability has become a competitive asset in a category that never previously required one.
