Oral Irrigator Patents: Leaders, Trends & White Space 2026
Oral irrigator and home dental care device patents: who holds the claim space now
Concentrated at the top. The leading five assignees hold 279 of 349 records in scope — 79.9% of the field — leaving a long tail of single- and few-filing entrants. Filings rose from 2 records in 2017 to a peak of 105 in 2021, then fell to 12 by 2024 — an 89% decline over that three-year span. Because publication typically lags filing by around 18 months, the 2025 and 2026 counts shown are still incomplete and should not be read as confirmation the field has gone quiet.

Common questions on oral irrigator patents
Who holds the most patents in oral irrigators and home dental devices?
The ranked list covers 37 companies, and it is heavily front-loaded: the leading assignee alone accounts for 116 of the 349 records in scope, versus 14 at fifth place and 6 at tenth. The top five assignees combined hold 279 records, or 79.9% of the field. That level of concentration means a new entrant is filing into space already well covered by a small number of established players, particularly in core dentistry-framed claims (A61C).
Is the oral irrigator patent field still growing?
Filing volume peaked at 105 records in 2021 and had fallen to 12 by 2024, an 89% drop over that three-year span. That looks like a clear slowdown, but publication typically lags filing by around 18 months, so the 2025 and 2026 figures in the dataset are still incomplete. The honest read is that the field passed its peak filing intensity several years ago and has since consolidated, rather than that it has stopped moving entirely.
What technical areas in oral irrigators are least covered by existing patents?
Relative to the dominant A61C dentistry classification, which covers 80.2% of the 349 records, several adjacent mechanisms are thinly claimed: positive-displacement pump architecture (F04B) sits at 4.9%, digital data processing and app connectivity (G06F) at 2.9%, and image-based processing (G06T) at just 2.6%. These lower-density classes are where a specific, mechanism-level claim is less likely to run into dense prior art than a general device claim would.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Oral Irrigators and Home Dental Care Devices covering 2015–2026, data cut-off 2026-07-31.
