Career Information

Dental hygienists work in clinical, corporate, public health, research, and educational settings. They can serve as program administrators, and some have become successful entrepreneurs, starting their own businesses.

Dental hygienists provide a range of preventive and therapeutic dental services, including dental hygiene assessment and care planning. Services include oral dental and periodontal examination, scaling and debridement, pain management, radiography, dental sealants, in-office whitening, and oral hygiene instruction. Dental hygienists are professionals, licensed by the state in which they practice, who complete extensive educational and clinical preparation in oral disease prevention.

The salary of a dental hygienist depends on the responsibilities associated with the specific position, the practice setting, and the geographic location of employment. Full- or part-time employment and benefits are factors. Dental hygienists earn salaries equal to healthcare personnel with similar training and experience such as nurses.

NHTI encourages students to research the dental hygiene career and connect with local association members. Students may join an association at a reduced rate as a student member. The student chapter of the American Dental Hygienists’ Association is an active service organization at NHTI.

NHTI encourages dental hygiene graduates to pursue a bachelor’s degree. Our graduates successfully transfer to colleges and universities around the country. Because of the extensive knowledge and skills of dental hygienists, professional organizations are discussing the bachelor’s degree as the entry-level degree for dental hygiene.

Students are subject to random screenings throughout the program without exception. Students learn procedural and cost information during the admissions process and are responsible for associated testing costs.

Bloodborne Pathogens and Infectious Diseases

Dental Hygiene students may be exposed to blood-borne pathogens and infectious diseases. Faculty provide students with theory and instruction on infectious diseases, mechanisms of disease transmission, and infection control procedures to reduce the risk of disease transmission. Current instruction includes protocols published by national public health agencies, the Occupational Safety and Health Administration, and the U.S. Centers for Disease Control and Prevention.

Health Requirements

Once admitted, students must provide documents for clinical clearance to the Health Services Office by the deadline. Failure to do so will prohibit them from entering the program. Students must maintain clinical clearance throughout the program to remain enrolled and progress in the program.

NHTI arranges professional liability insurance for students, applying fees to student accounts.

Health, Character, and Technical Standards

Dental Hygiene students must demonstrate the knowledge, skills, and behaviors deemed essential for the practice of dental hygiene. The program adheres to the NHTI Statement of Nondiscrimination. Reasonable accommodations for students with disabilities are made to the extent that there’s no fundamental alteration to curriculum, course objectives, or health, character, and technical standards of the program.

Students must be able to learn, integrate, analyze, and synthesize data. Comprehension of three-dimensional and spatial relationships is necessary. Consistent, accurate, and quick integration of information is required, especially in emergency situations.
  • Somatic sensation and functional use of all senses is required. Exteroceptive (i.e., touch) and proprioceptive (i.e., position, pressure, movement) is mandatory. Students must also be able to observe demonstration at a distance and close at hand; performance of procedures in the classroom, lab, and clinic is required. Students must be able to see fine detail, focus at several distances, and discern variations in color, shape, and texture to differentiate normal and abnormal structures. Students must be able to use tactile sense to perceive and interpret vibrations associated with clinical procedures. Visual and intellectual ability is necessary to acquire information from documents such as charts, radiographs, computer images, and other modes of delivery. Students must have sufficient hearing to develop reasonable skills of percussion and auscultation.
  • Sufficient fine and gross motor function is required to perform a variety of clinical procedures essential to providing dental hygiene care for patients. Examples of essential motor skills include manipulation of small objects and materials, palpation, percussion, auscultation and other maneuvers. Fine motor ability is a critical necessary skill. Gross motor ability is required in order to perform functions such as basic life support, transfer and position of patients as well as the operator position around the patient and dental chair. Students must be able to operate both foot and hand controls.
