What Do Dental Hygienists Do?

When you visit a dental office, you often interact with multiple team members with various job titles. Do you know the difference between a dental hygienist, a dental assistant, and a dentist? To answer this question, we’ll explain how dental hygienists differ from both a dental assistant and a dentist.

What Is A Dental Hygienist & What Do They Do?

Dental hygienists specialize in cleaning teeth, removing plaque, tartar, and stains. They’ll check your teeth for signs of oral disease or gingivitis, and even educate you on how to maintain good oral health. They are often involved with removing sutures and dressings, administering local anesthetics, collecting your medical history, and keeping track of your dental conditions for the dentist.

How Do They Differ From Dental Assistants?

Dental assistants can also educate patients about good oral hygiene strategies, but they aren’t allowed by law to clean your teeth, under any circumstances. Only a licensed dentist or licensed dental hygienist is allowed to do that. However, dental assistants can help the office run smoothly through various administrative functions, handing instruments to the dentist while they are performing a procedure, sterilizing dental equipment, cleaning the exam rooms, taking and developing dental X-rays, and more.

How Do Dental Hygienists Differ From Dentists?

While a dental hygienist may clean your teeth and provide general preventive care, it’s the dentist that will conduct the actual examination and perform complex procedures, such as tooth extractions, dental fillings, dental implants, and root canal therapy. They can also write prescriptions, diagnose dental issues, analyze X-rays, and more. Moreover, while both must be licensed to practice, dentists have at least a bachelor’s degree and then attend four years of dental school. Some even complete additional education to specialize in a certain field of dentistry (like our very own Dr. Brittany Stroope!) In contrast, dental hygienists require at least a two-year associate degree.

From the time I walked through the door I was treated with understanding & kindness. Everyone that I dealt with are very knowledgeable, patient & kind. I had avoided dentists longer than I care to admit but once I found Nick Dollar I will never look for another dentist. I recommend his office to ANYONE who is looking for a dentist. No one asked me to give a review...I did it because I truly believe in his work, people skills & staff is top notch. I usually dont take this kind of time for reviews but they are worth it.

So I’ve neglected going to the dentist for half my life and I decided to go here because this was the last place I went when I was 16. They still had me on file, Toni at the front desk was more than helpful. Full of laughter. The coffee machine was on point. And Ashley in the back made the scary experience enjoyable and full of positives that I will surely carry with me. See y’all at my deep clean.

I've been going to Farmington Dental for years and have never had a negative experience. I only write this review now because I had a particularly helpful visit. While there for a routine cleaning, I got to talking with Kristin about the microbiology classes I teach. She made some observations that inspired me to approach the latter half of the semester differently, and it was a super helpful change! I guess all that is to say that the workers are competent...but also pleasant and helpful. :P

I’ve had traumatic dental experiences in the past and am unfortunately one of those people who require a little more juice to get fully numbed. Farmington Dental not only managed to numb me completely but also prescribed an anxiety medication for the visit which helped ease the tension of getting in the chair. This is one of two dental experiences I can remember without experiencing pain and the other experience I was asleep. I’ll definitely be going back.
