How a hygienist is trained
Dental hygienists complete a college program in dental hygiene, usually after taking science classes in high school. The program includes supervised clinical work with real patients. They then earn a state license, and the National Board Dental Hygiene Examination is part of that process.
Screening before the exam
Before the dentist comes in, the hygienist checks for signs of tooth decay and gum disease and passes along what they find. Screening usually includes:
- Your health history
- A head and neck check
- Blood pressure and pulse
- An oral cancer screening
- X-rays when they are needed
Cleaning and tools
Hygienists use simple tools like a mirror, along with power and ultrasonic instruments that polish teeth and gently shake loose plaque. Some of the more advanced tools include lasers and an intraoral camera. Hygienists can also apply fluoride and sealants, and take impressions when you need a crown, implant, denture or mouth guard.
What happens at your visit
- The hygienist brings you to the exam room and asks about your health and any concerns with your teeth or jaw.
- If you need X-rays, they are taken first.
- They measure your gums, remove plaque and tartar, polish your teeth and floss.
- When the dentist arrives, the hygienist points out anything that needs a closer look and helps with the exam.
- Afterward they answer your questions and update your chart.
Teaching and care instructions
Many patients know how to brush and floss but not much more. Your hygienist can show you better technique and put you at ease, especially if it has been a while since your last visit. They also explain any instructions or restrictions you should follow after a treatment.
Keeping your records
Hygienists write down what was discussed and done at each visit. Your dental record holds your personal details plus your medical and dental history. It helps us follow up on your care, it is a legally binding medical document, and it can be sent to other providers or specialists when you need it.

Common questions
What is the difference between a hygienist and a dentist?
The hygienist screens, takes X-rays, cleans your teeth and looks for possible problems. The dentist comes in afterward to examine you and handles the more complex procedures.
What is the difference between a dental assistant and a hygienist?
Assistants take X-rays, prepare instruments, take impressions and help the dentist. Unlike hygienists, they do not collect health histories, remove plaque from teeth, apply sealants or fluoride, or keep patient records.
Does a hygienist need a license?
Yes. Hygienists graduate from a dental hygiene program and meet the licensing requirements of their state, which include the National Board Dental Hygiene Examination.
What else can a hygienist do?
They can help the dentist during procedures, update your chart, show you how to care for your teeth, apply fluoride and sealants, and take impressions.
