How Much Revenue Is Your Hygiene Department Actually Leaving on the Table?

Ask a dentist and a hygienist the same question about the same appointment and you get two different answers.

We surveyed 102 dentists, hygienists, and office managers for The State of the Hygiene Appointment 2026. Seventy-two percent of dentists said they were very confident their hygiene appointments meet best-practice standards. Twenty-nine percent of hygienists agreed.

That is a forty-three point gap inside the same practice. And it usually shows up in one number.

The number most practices can't produce on demand

What share of your hygiene codes are periodontal codes?

Most owners can't answer that without pulling a report. When they do pull it, the answer is usually under 3%. That is the national average. Wendy Briggs, RDH, who has audited thousands of practices, says most of the ones she sees come in under 2%.

The benchmark is 20 to 30%.

Periodontal disease affects 47% of adults 30 and older, according to the CDC. More than 70% of adults 65 and older have it. A practice billing perio on 2% of its hygiene codes is not seeing a healthier population than everyone else. It is not finding what is there.

This is not a skill problem. It's a time problem.

Two more findings from the same survey:

• 11% of practices chart full-mouth perio at every hygiene appointment.
• 60% say full-mouth perio charting is the first task cut when the schedule runs behind.

Read those together. Full-mouth charting is the first thing to go, and it goes often enough that only one practice in nine still does it every time.

Briggs tells a story about an audit of a highly progressive fifteen-suite practice. Excellent clinicians, good systems, busy schedule. Only 19% of their patients had a periodontal chart recorded in the last two years.

"If you're not doing a full comprehensive chart, you're not going to find it."

You can't bill what you didn't diagnose. You can't diagnose what you didn't chart. Everything downstream of the chart — the conversation, the treatment plan, the code — depends on an exam that actually happened.

What the gap is worth

Briggs doesn't ask practices to go from 2% to 30%. She asks for ten percent in year one.

For a solo hygienist seeing about 1,200 patients a year, perio codes at 1% utilization run roughly $12,000. Briggs puts a 10% improvement on that at $120,000 to $150,000. For a practice running three or four hygienists and 4,000 patients, the same 1% utilization is closer to $40,000 today, and the same 10% move is worth $400,000 to $600,000.

"Year one, we just want a 10% increase. We're not going from 2% to 30% overnight. But that 10% bump is still hundreds of thousands of dollars."

Nothing in those numbers requires a single new patient, a new operatory, or a longer day.

Check your own practice in about ten minutes

Pull these six numbers for the last twelve months and put them next to the benchmark.

• Hygiene share of total production — under 25% is underperforming; target 30 to 35%.
• Production per visit, non-assisted — under $150 is underperforming; target $200 to $300 and up.
• Fluoride acceptance rate — under 50% is underperforming; target 80% or better.
• Perio codes as a share of hygiene codes — under 5% is underperforming; target 20 to 30%.
• Perio chart frequency — spot probing or "only when something looks wrong" is underperforming; target a full chart at least annually.
• SRP case acceptance — under 40% is underperforming; target 60% or better.

Start with the perio row. It is almost always the widest gap, and it is the one that moves the others.

The fix is not a target on your hygienist

The reflex is to set a number and hold the team to it. That is the wrong move, and it is the fastest way to lose a good hygienist.

Look again at why charting gets cut. It is not reluctance. It is a thirty or forty minute appointment with a full-mouth exam, radiographs, a cleaning, preventive services, and a real patient conversation in it. When something has to give, the longest task on that list — the one that normally needs a second set of hands to record — is what gives.

The goal is not more treatment. It is a complete exam on every patient. Do that and the diagnosis follows, the conversation follows, and the codes follow. Skip it and none of them can.

So the question isn't how to make your team chart more. It's how to give the appointment enough room that charting stops being the thing that gets cut. In the same survey, 52% of practices said they want technology to reduce documentation time. They already know where the room is.

Where Alta Voice fits

Alta Voice Perio charts the exam by voice. Your hygienist calls out pocket depths, bleeding points, recession, and mobility, and the chart fills in while both hands stay in the patient's mouth. No second person recording. No stopping to type. Practices report up to 60% less time spent on charting and four to eight minutes back on every hygiene appointment.

That matters for one reason. The full-mouth chart still happens on the day you're running behind.

Two things worth doing this week

Pull your perio code percentage. Just that one number. If it starts with a 1 or a 2, you now have a rough idea what that is worth.

Then read what your peers said about the appointment itself — where the time goes, what gets cut, and why the dentist and the hygienist so often describe the same thirty minutes differently.
