These professionals are often the first line of defense in preventing dental issues and promoting overall oral health. Their work not only helps individuals maintain their smiles but also contributes to their overall well-being.

The Educational Path

Becoming a licensed dental hygienist requires a structured educational journey. Here are the essential steps:

Next, you’ll need to enroll in an accredited dental hygiene program, typically offered at community colleges, technical schools, or universities. These programs usually take around two to three years to complete and culminate in an associate’s degree or bachelor’s degree in dental hygiene.

During your program, you’ll gain knowledge in subjects such as anatomy, physiology, radiography, and dental hygiene techniques. You’ll also gain practical experience through clinical rotations, allowing you to apply what you’ve learned in a real dental setting.
