A career as a dental hygienist is one of the highest-paying vocational jobs you can find. The average income for a dental hygienist is over $70,000 per year, and some offices offer great benefits, including vacation and sick days.
Dental hygienists are well paid for their work. They earned an average wage of $69,760 per year as of May 2011, according to the Bureau of Labor Statistics. Some hygienists earn much more, though. The top 25 percent of earners made annual salaries at or above $83,310, and the top 10 percent made annual salaries at or above $94,850. The good news for dental hygienists is that if they get tired of working in one office they should have no trouble finding work in another. The bureau projected a 38-percent increase in jobs for hygienists from 2010 to 2020. Research studies that show the importance of oral health to overall health have contributed to demand for dental practices, and subsequently, hygienists.
