Your Best Hygienist Will Leave This Year - Here's What It Costs and How to Stop It

Run the numbers before you read anything else: losing one full-time hygienist for a single hiring cycle costs a typical two-hygienist practice roughly $70,000 in lost production, temp coverage, recruiting, ramp-up, and lapsed recall. Keeping that same hygienist by paying $4 more per hour costs about $5,900 a year. That's the whole argument. Everything below is the arithmetic and the specific moves that make the retention side actually work.

The reason this matters right now is that the hygienist labor market never went back to normal after 2021, and the demographic math says it won't. If you have two hygienists, the odds that neither of them is currently browsing job postings are not in your favor.

The Odds Are Worse Than You Think

Start with what hygienists say about their own plans. RDH Magazine's 2024 salary survey of 1,802 hygienists found that 19% had changed jobs in the previous year and 42% were actively looking for new opportunities. Not "open to a conversation." Actively looking.

The newer DentalPost industry salary report softens that a little and sharpens it in another direction. It found 71% of hygienists say they're happy in their current job, which sounds reassuring until you read the next line: 27% are still considering leaving their current role for higher pay, a better work environment, or better benefits. Happy and leaving are not mutually exclusive. A hygienist can genuinely like your team, like your patients, like your operatory, and still take $6 an hour more across town. That same report found nearly three in ten hygienists plan to retire before or by 2030.

So model it this way. If roughly a quarter of hygienists are considering a move in any given year, and you employ two, the chance that at least one of them is in that group is high enough that you should be planning for it rather than hoping around it. That's not a scare tactic. That's just how independent probabilities work when the base rate is 27%.

Why This Cycle Is Different

Practice owners have been told about staffing shortages since 2021 and a lot of you have tuned it out. Fair. But the supply side has structurally changed, and the numbers make that clear.

The Bureau of Labor Statistics counts about 225,300 employed dental hygienists, projects 8% employment growth from 2025 to 2035, and projects roughly 15,000 openings per year on average over that decade. Most of those openings come from replacement, meaning people leaving the occupation entirely, not new operatories opening. Layer the DentalPost retirement finding on top of that: a large retirement wave is inside a labor pool that already can't fill its annual openings.

On the demand side, the ADA Health Policy Institute reports that only 60% of dentists say they have an adequate number of hygienists on staff, and among dentists actively recruiting one, 91% called the process very or extremely challenging. ADA News confirmed the same pattern in its five-year retrospective: about 62% of dentists named staffing shortages their single biggest practice challenge heading into 2025, roughly 90% of those recruiting a hygienist in late 2024 called it very or extremely challenging, and 30% to 40% of dentists were actively recruiting a hygienist or assistant at any given moment.

Read that last stat again. A third of your competitors are recruiting right now. Your hygienist doesn't have to go looking for an offer. An offer will find her.

The one piece of good news in the ADA data is direction: the "very or extremely challenging" figure fell from about 95% in late 2022 to about 90% in late 2024. The market is loosening. It is loosening at roughly two and a half points a year, which means you are still hiring into a hard market for the rest of the decade.
