Hygiene Department Profitability

Hygiene is the backbone of most general dental practices. It brings patients back twice a year, creates most restorative treatment, and can be profitable on its own. But when the schedule has gaps or fees fall behind wages, hygiene can quietly lose money. This calculator shows whether your hygiene department covers its own labor and supplies, and how hygienist pay compares with what hygiene collects.

What this calculator does

Enter the number of full-time hygienists, their hourly wage and paid hours, days worked, payroll taxes and benefits, patients per day, average hygiene collections per visit, the collection rate, supplies per visit and the doctor's exam collections per visit. It shows:

• hygiene profit per year, before facility and front-desk costs,
• hygiene collections per year,
• hygienist pay as a percentage of hygiene collections,
• collections per hygienist per day, and
• doctor exam collections that come from hygiene visits.

The formula in plain English

Visits per year = hygienists × days × patients per day.

Hygiene collections = visits × average fee per visit × collection rate.

Labor cost = hygienists × hourly wage × paid hours per day × days × (1 + payroll taxes and benefits %).

Hygiene profit = collections − labor cost − (visits × supplies per visit).

Labor ratio = labor cost ÷ hygiene collections. A ratio near 33% is a common target.

Exam collections = visits × exam fee × collection rate. This is shown separately because it's doctor production.

A worked example

Dr. Foster's practice has two full-time hygienists earning $52 an hour for 8 paid hours a day, 210 days a year, with 18% in payroll taxes and benefits. Each sees 8 patients a day, averaging $185 in hygiene collections per visit at a 97% collection rate, with $9 in supplies per visit.

• Visits: 3,360 a year.
• Hygiene collections: about $602,950.
• Labor: about $206,170, or 34.2% of collections, slightly above target.
• Hygiene profit before facility costs: about $366,540.
• Per hygienist per day: about $1,436.
• Doctor exams: about $179,260 more from those visits.

Raising average collections per visit by $15, through better perio diagnosis, fluoride and sealants where appropriate, or a fee review, would bring the labor ratio down to about 31.6%.

Why it matters at each career stage

If you're: Practice owner

Look at this whenever you hire a hygienist or raise wages. In a tight labor market, raising pay may be necessary. The way to protect margins is to keep the schedule full and diagnose and treat periodontal disease consistently.

If you're: Employed

If you're an associate, a strong hygiene program is where much of your restorative work comes from. Ask about hygiene schedules and recall rates when you compare offices.

Ways to improve hygiene profitability

Fill the schedule. Pre-appoint the next visit before patients leave, send reminders, and keep a short-notice list.

Diagnose periodontal disease consistently. Using clear criteria for periodontal treatment and maintenance helps patients and is often under-done.

Review your fee schedule. Hygiene fees that haven't changed in years fall behind rising wages.

Use assisted hygiene carefully. An assistant can let a hygienist see more patients, but only works with enough demand.

Watch cancellations. Track them by day and time to spot patterns.

Hygiene and the rest of the practice

Hygiene's true value goes beyond its own profit. Most fillings, crowns and other restorative treatment are found during hygiene exams. A practice with a full, consistent hygiene schedule has a steady stream of treatment for the doctors, while a practice with an empty hygiene schedule often struggles to keep the doctor busy.
