Overtime Rules for Dental Offices: Workweeks, Daily Overtime and Comp Time

Overtime starts with the workweek.

Under the Fair Labor Standards Act (FLSA), a non-exempt employee must be paid at least one and one-half times their regular rate for every hour worked over 40 in a workweek.

The law sets no ceiling on how many hours an employee aged 16 and older may work in a week, and it does not require premium pay for weekend or holiday work as such — only for the hours that pass 40.

A workweek is a fixed, regularly recurring period of 168 hours — seven consecutive 24-hour periods.

It need not match the calendar week: it can start on any day and at any hour, and different employees can have different workweeks, say Monday–Sunday for the front desk and Saturday–Friday for chairside staff.

Once an employee's workweek start is set, it stays fixed; you can change it only if the change is intended to be permanent and is not designed to evade overtime.

Two workweek mechanics to watch:

• No averaging. The FLSA takes a single workweek as its standard and does not permit averaging hours over two or more weeks. An employee who works 30 hours one week and 50 the next is owed overtime for the 10 extra hours in the second week — even on a biweekly pay schedule.
• All hours count together. You must total every hour an employee works for you in the workweek, even across unrelated assignments — chairside Monday, front desk Tuesday. Hours worked for joint employers are added together, which matters when one owner's practices share staff; whether two offices count as joint employers is fact-specific.

Three rules keep the 40-hour line honest.

Overtime earned in a workweek is generally paid on the regular payday for the period in which that week ends.

The overtime requirement cannot be waived by agreement between you and your employees.

And an announcement that overtime will not be permitted, or will not be paid unless authorized in advance, does not impair an employee's right to be paid for overtime hours actually worked.

Salaried staff are not automatically outside the rule: a non-exempt employee is owed overtime whether paid hourly or by salary, and a fixed salary for a workweek longer than 40 hours does not satisfy the FLSA.

Whether an employee is exempt at all is its own analysis — a duties test plus salary tests, not job titles.

Federally, the minimum salary for the executive, administrative and professional exemptions is $684 per week as of this guide's October 2026 check.

The regular rate is where dental overtime math goes wrong, because it is more than the hourly rate whenever a bonus or commission is part of the pay.

It is an hourly figure: total pay for the workweek, minus the statutory exclusions, divided by total hours actually worked — whatever the pay basis.

It includes all remuneration for employment except what the statute excludes, and it cannot be set by agreement: a handbook line saying overtime is paid on base rate only does not decide it.

Some payments stay out of the calculation: reimbursed expenses, genuine overtime and holiday premiums, discretionary bonuses, gifts on special occasions, and pay for occasional periods when no work is performed — vacation, holidays, illness.

A bonus tied to a predetermined formula — production bonuses, attendance bonuses — does not qualify for that exclusion and must be included.

A bonus is nondiscretionary when employees know about it and expect it, and the fact that you keep the option not to pay a promised bonus does not make it discretionary.

To count as discretionary, you must retain discretion over both whether to pay and how much until quite close to the end of the period the bonus covers.

One structure settles the math on its own: a bonus paid as a percentage of total earnings — both straight-time and overtime earnings — satisfies the overtime rules on the bonus without recomputation, as long as the plan is not a device to evade overtime.

Commissions and production pay belong in the regular rate too, whether the commission is the sole pay or sits on top of a salary or hourly rate.

When a commission is paid weekly, it is added to the week's other earnings and divided by total hours worked to get the regular rate, and the employee is owed an extra half of that rate for each overtime hour.

Paying commissions monthly, or on any delayed schedule, does not excuse you from including them; when a commission covering several weeks is paid later, you may pay overtime on the base rate first, but the additional overtime due on the commission must be paid once it can be computed.

Our research found no DOL document written for dental hygiene pay specifically, but the commission rules are generally read to cover percentage-of-production pay for a non-exempt hygienist.

The math differs by pay basis; the overtime duty does not:

Banking overtime hours as future time off — comp time — is a public-sector tool.

The FLSA authorizes compensatory time off in lieu of overtime pay only for employees of public agencies: states, political subdivisions and interstate governmental agencies.

A dental practice is a private employer, so the arrangement is not available to you.

Colorado's labor department puts the same point plainly for its employers: you cannot give time off instead of time-and-a-half overtime pay.

The no-waiver rule closes the workaround — an employee cannot agree to skip the premium, and a handshake deal to trade this week's overtime for a day off next month does not hold.

Offering paid time off as an ordinary benefit is a different thing entirely; the bar is on substituting time off for overtime pay that is already owed.

If the schedule is what pushes people past 40, fix the schedule and the pay design — not the paycheck.

Federal law asks only a weekly question, but state law can add a daily one: overtime that starts before an employee reaches 40 hours in the week.

Four states whose rules a dental schedule can hit are California, Alaska, Nevada and Colorado.

That is not a complete list of every state with a daily trigger, so confirm your own state's rule with its labor department.

Longer-day schedules are where these rules collide.

A four-day, 10-hour hygiene week sits at exactly 40 hours, so it creates no federal weekly overtime — but in Alaska and California each 10-hour day crosses the daily trigger.

Nevada's daily rule steps aside for an agreed four-day, 10-hour schedule, and Colorado's 12-hour daily threshold leaves a 10-hour day inside the weekly rule.

A longer-day schedule in California also raises questions this page does not cover, so confirm them with the Labor Commissioner's office or your employment counsel before you set one.

Overtime problems can start with the schedule — but the minutes around it count too.

Under the FLSA, work not requested but suffered or permitted is work time: if you know or have reason to believe an employee is working — finishing charts after the shift, for example — the time must be counted.

The workday generally runs from the start to the end of the employee's principal activities, so it can be longer than the scheduled shift on the board.

Mapped onto a practice: if you know or have reason to believe the work is happening, the operatory setup before the first patient, the morning huddle, and the charting and sterilization after the last one are all hours worked.

The same holds for work done away from the office — the notes an assistant finishes at home in your practice-management system, say — which must be counted if you know or have reason to believe it is being done, and none of it becomes non-compensable because you did not ask for it.

Lunch has its own trap.

A bona fide meal period — ordinarily 30 minutes or more — is unpaid only if the employee is completely relieved from duty; an employee required to perform any duties while eating is working.

DOL's own example is the employee who stays at the desk through lunch and regularly answers the phone: that employee is working and must be paid for the time.

A written "no off-the-clock work" rule does not fix this by itself.

Federal rules are blunt: the mere promulgation of a rule against such work is not enough — management must enforce it and cannot accept the benefit of the work without paying for it.

What works is pairing the policy with timekeeping that captures the time, and with staffing that does not depend on invisible minutes.

The carve-out is narrow: employees who voluntarily come in before their starting time or stay after closing without doing any work need not be paid for those periods.

In California, Wage Order 4 — the wage order the Labor Commissioner assigns to dental offices — defines hours worked as the time an employee is subject to the employer's control, including all the time the employee is suffered or permitted to work, whether or not required to do so.

So in California the setup-and-cleanup minutes are hours worked even when nobody ordered them.

Overtime compliance is provable or it is not.

For each non-exempt worker, FLSA records must include, among other items, hours worked each day, total hours each workweek, the basis of pay, the regular hourly rate, total overtime earnings, deductions, and total wages each pay period.

Federal law requires no particular timekeeping method — a time clock, a timekeeper or employee-written times are all acceptable — as long as the records are complete and accurate.

If you round punches, rounding clock times to the nearest 5 minutes, tenth or quarter hour is accepted only if, over a period of time, it does not result in failure to pay employees for all the time they have actually worked.

Keep payroll records for at least 3 years, and keep time cards and other basic time-and-earnings records showing daily starting and stopping times — plus wage-rate tables — for at least 2 years.

The exposure is not theoretical: an employer that violates FLSA minimum wage or overtime rules owes the unpaid wages plus an equal additional amount as liquidated damages.

Overtime is one slice of running a compliant, well-staffed practice — the dental hiring hub collects the rest of our employer guides, from pay design to screening.
