Dental Hygienist Training and Certification Process Details

In order to become a dental hygienist, a candidate must first complete a college program in dental hygiene. Students in the program may earn an associate degree at a community college, a bachelor's degree at a four-year university, or a graduate degree. Admissions to programs in dental hygiene usually require a background of high school courses in science.

After completing the academic college-level courses, dental hygienist candidates must then complete a supervised clinical experience with patients. Once the program is finished, dental hygienists must earn their state license in the practice. According to the American Dental Association, some states also require candidates to earn a passing score on the National Board Dental Hygiene Exam.

How Dental Hygienists Help With Patient Screening

During routine exams and cleanings, dental hygienists may also assist the dentist with patient screenings for some conditions. They may assess the patient's oral health and use the periodontal chart to evaluate the patient's potential for gum disease. They may also inquire about any other health issues or chronic conditions for the patient.

Some dental hygienists may also perform cancer screenings during the examination, such as oral cancer. These dental professionals also examine the head, jaw, and neck to spot potential problems. Dental hygienists also may take X-rays of the teeth and mouth to determine if there are cavities or other oral issues.

Recommendations and Documentation

Another aspect of a dental hygienist's job is to counsel patients and provide advice for optimal oral health. They may educate patients about the importance of proper brushing and flossing and provide suggestions for oral hygiene techniques. Dental hygienists also may offer recommendations for different types of toothbrushes and flossing products.

Proper oral care at the dentist also requires documentation of treatment and the condition of the patient's mouth and teeth. The dental hygienist works with Desert Dream Dentistry & Spa to document the condition of the gums, teeth, and screening results. Effective record-keeping helps providers monitor possible problem areas.

When a Dental Hygienist Treats Patients

Dental hygienists are usually involved in a patient's regular, routine cleaning appointment. It is vital to schedule periodic appointments according to the dentist's recommendations. During a standard appointment, the patient may start treatment with the dental hygienist. Here are the parts of the visit where a dental hygienist may be involved:

• Health History: Before starting any examination or cleaning, the dental hygienist may first review the patient’s health and history. The dental provider reviews the patient’s dental records and health information. Then, the provider may discuss the patient’s concerns before going to the next step of the appointment.
• Teeth Cleaning: Next, the dental hygienist cleans the teeth. They may use a professional polisher to remove build-up and stains on the enamel. They also use tools to remove tartar and plaque from the teeth and the gum line.
• Fluoride Treatment: Some dental hygienists may provide preventative services during a routine visit. Fluoride treatment helps keep the teeth healthy and strong. Dental sealant application to prevent tooth decay may also be part of a routine appointment.

Frequently Asked Questions About a Dental Hygienist

Q. What is the difference between a dental hygienist and a dentist?

A. Dental hygienists and dentists have very different roles within a dental practice. A dental hygienist will conduct oral screenings, update your patient information, take x-rays, do a thorough cleaning, and look for potential problems. The dentist will come in following the cleaning to do an exam and will also handle more complicated procedures.

Q. What sort of training do dental hygienists have?

A. Dental hygienists have graduated from an accredited dental hygiene program and have taken and passed state exams to receive their license. During their studies, dental hygienists take classes in head and neck anatomy, pathology, nutrition, and medical ethics. Most programs take about three years to complete.

Q. What do dental hygienists do?

A. Dental hygienists have several different roles in an office. They can assist the dentist during procedures, update the patient's chart, show patients how to care for their teeth, perform oral health screenings, and remove plaque from the teeth. They can also apply fluoride and sealants to teeth as well as take impressions.

Q. What is the difference between a dental assistant and a dental hygienist?

A. It can be easy to confuse dental assistants and dental hygienists as they perform many of the same duties. Dental assistants can take x-rays, prepare instruments and equipment, take impressions of the teeth, and assist the dentist during procedures. However, unlike dental hygienists, they do not collect patient health history, remove plaque from the teeth, apply sealants or fluoride, or do any patient documentation.

Q. Does a dental hygienist receive certification or licensure?

A. Dental hygienists must complete at least an Associate's degree in dental hygiene. They must then pass the National Board Dental Hygiene Examination (NBDHE) in order to achieve licensure. This exam is the only one required by all 50 states.
