This left-handed hygienist cannot be the only one who has had to decline an amazing job offer to work in a beautiful practice because the operatory was set up for a right-handed clinician.

Only about 10%–12% of the population is left-handed, and dental operatories are overwhelmingly designed with right-handed clinicians in mind.1 The result? Physical barriers, inefficient workflows, and a surprising amount of self-taught adaptation. Many left-handed clinicians learn through trial and error—unless they were fortunate enough to train under a left-handed or ambidextrous instructor. The rest of us? We figure it out as we go.

As a left-handed hygienist and ergonomic specialist, I have spent years breaking down the most common challenges—and more importantly, the solutions.

Obstacle 1: Delivery systems

The primary problem left-handed clinicians face in the operatory is delivery systems. When you can’t easily access your delivery tray, you are forced into repeated reaching and trunk-twisting—often under load. These movements are two of the primary contributors to musculoskeletal injury among dental professionals.²

Solution: move the delivery system. If using a rear-delivery unit, swivel it toward your dominant side. If using a chair-mounted system, rotate the delivery tray counterclockwise or across the chair to bring it to the left side. If the system can move—move it.

Obstacle 2: The patient chair

Patient chairs aren’t bolted to the floor. Consequently, they’re often moved toward the left side of the operatory to give a right-handed clinician more room to move. The obvious obstacle is that there is less room to move the delivery system or other items into a lefty position.

Solution: move the chair. Yes, they’re heavy—get help if needed. Even a few inches to the right can create enough clearance to properly position the delivery system and clinician. Where possible, consider swiveling the patient chair opposite the direction of the delivery system to allow for 12 o’clock positioning.

Obstacle 3: Hygiene school vs. real-world

Another common struggle left-handed clinicians often experience is a disconnect between what was taught in school and what works in practice. With fewer left-handed instructors, many clinicians rely on guesswork instead of guidance.

Solution: let your body guide patient positioning. If your wrist is in flexion, turn the patient away from you. If your wrist is in extension, turn the patient toward you. This may require pivoting your fulcrum or shifting clock positions to avoid chicken-winging.

Obstacle 4: Constantly reaching

One last, but not least, struggle is frequent reaching in general—for saliva ejectors, mechanized scalers, lasers, keyboards or a mouse placed out of reach that leads to trunk-twisting under load, especially during repetitious tasks like periodontal charting.

Solution: bring it all in. Ergonomic guidelines recommend keeping frequently used items within the primary reach zone—generally within approximately 12–16 inches of the body—to minimize shoulder strain and reduce the risk of musculoskeletal injury.³ Consider a cordless keyboard or mouse moved to the left. There are voice-activated software systems and small wireless keypads that can be affixed to closer surfaces by Velcro to enter periodontal assessment data. For saliva ejectors and other clinical accessories, bring them in. Consider placing the mechanized scaler insert into an empty slot on the delivery system for easy access. Bottom line? If you have to reach for it repeatedly, it’s too far away.

What can we take away from this? Being a lefty will likely always be accompanied by challenges, but they don’t have to leave us disabled or looking for ways to get out of the op. Move the delivery system, chairs, the patient, clock position, delivery tray, accessories to fit your needs. By adjusting things to your body, you avoid adjusting your body to everything else.
