Editor’s note: This is part of a new series spotlighting promising career paths that are filled with opportunity — yet don’t require a four-year college degree.

Amy Nguyen, 34, enjoys her plaque-busting profession because she 鈥渓ikes educating people on how to take care of their teeth. Dental health is extremely important — it promotes overall health.鈥 After earning her dental hygienist degree and working for four years in the San Francisco Bay Area, where she grew up, she now earns $100,000 a year.

How she got there

Her academic path was 鈥渃hallenging,鈥 she says, but not as painful as a root canal. Nguyen initially took at Chabot Community College in Hayward. She took in 鈥渕icrobiology, anatomy, physiology, chemistry, psychology, sociology, communications,鈥 she says. She was subsequently accepted into the two-year, full-time Dental Hygiene program, where she earned her Associate degree and took courses such as radiology, pathology, patient management, head and neck anatomy, local anesthesia, and periodontics (aka gum disease). She says her favorite hours were spent on 鈥渃linic work, actually seeing patients.鈥

狈驳耻测别苍鈥檚 at Chabot included tuition, books, liability insurance, parking, vaccinations, gowns, gloves, masks, fees for state and national examinations, and an instrument kit with dental tools, such as an ultrasonic power scaler.

Landing her first job

鈥淚 got my license in September and I got my first job in November,鈥 Nguyen says. She was hired by one of her instructors at Chabot; she says the helpful faculty members tend to keep students informed of openings. Employment for dental hygienists is enviable: the . claims “100% job placement of graduates who pass the State Board Examination is typical. This is expected to continue into the foreseeable future.鈥

The day-to-day grind

Nguyen presently works three days a week in Fremont, plus one day a week in Oakland, and once a week at the Native American Health Services in San Francisco. Wearing safety glasses, a surgical mask, and latex gloves to protect herself from infectious diseases, Nguyen meticulously inspects and cleans her patients’ teeth with a variety of hand, power, ultrasound, and laser tools. She seesaws floss between clients’ gnashers to remove food particles and snaps x-rays to detect cavities and jaw problems (like overbite). After relaying her discoveries to the dentist, she instructs clients in proper ongoing oral care, recommends products and, finally, bestows the ubiquitous free toothbrush and floss as a parting gift.

What special skills are needed to be a skilled dental hygienist?

Dexterity is essential, she says. Enormous, clumsy fingers lack the fine motor skills required to safely manipulate sharp tools into a fearful patient鈥檚 mouth. This is one reason why .

Critical thinking skills are crucial for correctly evaluating dental scenarios, and it鈥檚 important to be detail-oriented and adept at following specific rules and protocol. Last but not least, especially with the odontophobes, it’s imperative to be a compassionate person with strong interpersonal communication skills. 鈥淵ou have to be a 鈥榩eople person鈥欌 Nguyen says. 鈥淏ecause you鈥檒l be constantly talking and working with a lot of different kinds of people.鈥

Why is dental hygiene such a fast-growing profession?

Baby Boomers are aging, and they鈥檙e keeping their original teeth (with considerable help). Cosmetic services like teeth whitening are also increasingly popular. Thirdly, dental insurance is more readily available; which creates millions more mouths to attend to.

The bottom line

Not every dental hygienist gets paid as brilliantly as Nguyen, but the average wage is $72,910 per year. Regionally, the crown for top pay goes to Fairbanks, AK, where dental hygienists earn $105,730 annually 鈥 which is nothing to scowl at.

What’s in store

狈驳耻测别苍鈥檚 five- to 10-year plan is to earn a Bachelor of Science (a four-year college degree) in dental hygiene at California State University, East Bay. Why? Earning this diploma will make her eligible to teach at the more than 300 dental hygiene programs registered with the Commission on Dental Accreditation, a branch of the American Dental Association.

Does anything about dental hygiene just 鈥渂ite鈥?

Nguyen admits the work can be 鈥渢edious鈥 and it 鈥渃an be hard on your back and hands鈥 there鈥檚 a high risk of carpal tunnel because you鈥檙e holding such a small instrument.鈥 Any other drawbacks? 鈥淥ften you don鈥檛 get employed full-time at one office,鈥 explains Amy, 鈥渟o you don鈥檛 get any benefits.鈥

Flashing her pearly whites now, she brightens. 鈥淚 always wanted to do dentistry,鈥 she says. 鈥淚 like smiles and teeth.鈥
