Certificate programs can be completed in 2-3 years. Students will be educated in courses such as dental hygiene practice and theory, local anesthesia, dental pharmacology, oral and general pathology, and periodontology. The classroom part includes oral biology, community dental health, dental materials, nutrition in dentistry, and legal responsibility in dentistry. They also require high school diploma or GED, minimum age of 18, high school courses in math, chemistry, and English, minimum of a “C” average, and college entrance exam scores.
The salaries of dental hygienist vary. If you want to have a high salary, you should move to big cities because the prices tend to be more, or you can further your education so that you can make more money that way also. The normal hourly average is around 21 dollars an hour and for the yearly average it would be about 45,000 dollars to over $43 an hour, or $93,000 per year.
