A dental assistant's work outfit runs in two layers: the scrubs or uniform you arrive in, and the personal protective equipment that goes over it for patient care — safety glasses, a surgical mask, protective clothing and gloves, as the BLS job description puts it.
The rules that matter most attach to the second layer: OSHA requires your employer to provide and launder PPE at no cost to you, and taking it home to wash is not allowed.
Here is the full picture.
What does a typical dental assistant dress code look like?
Scrubs are the base layer of the job: a scrub top and scrub pants.
What varies is everything the dress-code policy adds on top — the color, whether the practice supplies the scrubs or expects you to bring them, whether you head home in them or change out at day's end, and the rules on jewelry, nails, hair and piercings.
Those day-to-day details live in the practice's own dress-code policy, so ask for it before your first shift.
State rules can reach into what you wear, too, which is why the policy is worth reading rather than skimming: California's infection-control rule, for example, dictates when protective attire must be changed — more on that below.
Dress-code rules tend to have practical reasons behind them: smooth, washable fabrics sit flat under PPE, short nails and minimal hand jewelry leave room for gloves and handwashing, and tied-back hair keeps the working field clear.
When a rule seems fussy, it is usually doing one of those jobs.

What PPE does a dental assistant wear chairside?
The protective layer is the part with federal rules behind it.
The Bureau of Labor Statistics' description of the job names the set directly: dental assistants wear safety glasses, surgical masks, protective clothing, and gloves to protect themselves and patients from infectious diseases.
BLS also notes that assistants follow safety procedures for x-ray machines — the radiation side of the work carries its own procedures, separate from the barrier wear.
Why the barrier is everyday wear rather than an extra: OSHA's dentistry topic page lists the hazards dental professionals may be exposed to, "the spectrum of bloodborne pathogens, pharmaceuticals and other chemical agents, human factors, ergonomic hazards, noise, vibration, and workplace violence."
PPE answers the exposure risks in that list — the bloodborne and chemical ones — which is why BLS's job description lists masks, eyewear, gloves and protective clothing as what dental assistants wear to protect against infectious diseases, not as surgical extras.
State infection-control rules can add detail on top of the federal baseline.
In California, for instance, title 16 section 1005 of the California Code of Regulations requires protective attire for procedures with potential spray, splash or spatter, changed daily or between patients if it becomes moist or visibly soiled, and reusable gowns laundered under Cal/OSHA's bloodborne pathogens standard.
What applies to you is federal OSHA plus whatever your state adds — your practice's policy is where the two meet.
Who pays for scrubs and PPE — and who does the laundry (OSHA)?
Start with the rule that settles the biggest money question.
Under OSHA's bloodborne pathogens standard — 29 CFR 1910.1030 — the employer shall clean, launder, and dispose of personal protective equipment required by the standard, at no cost to the employee.
If a garment is required PPE, it is not an employee expense.
Are scrubs PPE?
OSHA's interpretation letters draw the line by function, not by what a garment is called.
In a September 15, 1992 letter, OSHA stated that the standard requires the provision and laundering only of garments that are personal protective equipment: a uniform that is not PPE, and is covered by other protective garments, is not covered by that requirement.
But — quoting the letter — "If, however, a uniform provides an appropriate level of protection for workplace conditions and is worn, relied upon, and/or functions as a protective garment, the uniform would be covered by the standard."
The label "scrubs" decides nothing; whether the office relies on them as the protective layer decides everything.
And OSHA puts that determination on the employer: it is the employer's responsibility to determine whether there is occupational exposure and what PPE is appropriate.
Laundering has its own rule, and it surprises people.
OSHA's position is that employees are not permitted to take their protective equipment home and launder it — providing, laundering, cleaning, repairing, replacing and disposing of PPE is the employer's responsibility.
The dental-specific version came in a 1992 letter about gown laundering in a dental office: the standard "prohibits home laundering, but it does not prohibit the employer from laundering them on site as long as the cleaning and laundering is performed by trained individuals utilizing universal precautions and acceptable laundering methods."
On-site washing works; your washing machine at home does not.
The office does not need its own machines, either.
OSHA has said there is no requirement to purchase a washer and dryer, and contracting the laundering out to a service is an accepted option.
The trained-individuals condition is the one OSHA attaches to washing on site.
How dental offices set that training up is its own project: our infection control training guide covers it from the employer's side.
Wage law adds one more line, and it is narrower than it sounds.
Under FLSA regulations, where the nature of the business requires the employee to wear a uniform, the cost of uniforms and of their laundering is a facility primarily for the employer's benefit and cannot be counted toward wages.
That is a wage-counting rule, not a blanket ban on uniform charges — it matters where a uniform cost would bring a workweek's pay below the minimum wage.
If a uniform cost is coming out of your paycheck and you are not sure where it lands, the Department of Labor's Wage and Hour Division or your state labor agency can apply the rule to your situation.

Shoes and comfort: what works on the floor
Shoes rarely get a paragraph in the dress code until they are wrong.
The practical baseline for chairside work is a closed-toe, closed-heel shoe with a sole you can trust on a slick floor — instruments drop and fluids drip, and the operatory is no place for an open top.
Wipeable uppers matter for the same reason: whatever lands on the floor near the chair can land on your feet.
Comfort is a shift-length question, not a style one.
The work happens on your feet, at a chairside angle, so look for real arch support, a cushioned sole, and a fit that still works in hour six.
Rotating two pairs instead of wearing one out, and choosing a pair you can wipe down, are the small moves that add up over a week.
Dress for the room, not the weather.
Operatories can run cool, and a scrub jacket in your assigned color solves that without bending the dress code.
Keep a spare scrub set at work or in the car; the day a tray tips, you will want the swap to take seconds.
First-day tips: getting the outfit right
The fastest way to look settled on day one is to have asked a few questions before it: how many scrub sets the office goes through, whether there is a color or style rule, and how laundry works.
If the practice launders clinic gowns on site or sends them to a service, that is a good sign the PPE side is being handled the way OSHA describes — and that none of it should be riding home in your car.
- Ask for the dress-code policy in writing — colors, jewelry, nails, shoes
- Count your scrub sets: enough to change when one is soiled, not one set for the week
- Find where gloves, masks, eyewear and gowns are stocked in every operatory
- Confirm how the office launders its clinic gowns and PPE — on site or through a service; the protective layer is never home-washed
- Wear broken-in closed-toe shoes; brand-new shoes and long chairside days do not mix
- Keep day one plain: solid-color scrubs, minimal jewelry, hair tied back
If any answer comes back wrong — say, clinic gowns are expected to ride home in your car — raise it against the rules in the sections above rather than letting it slide.
Those rules are the office's to follow, not yours to absorb.
This page is general career and workplace information, not legal advice. PPE and laundering duties come from OSHA's bloodborne pathogens standard, and state infection-control rules can add to it; confirm what applies to you with your employer and, for your state, your state dental board or OSHA.
