What are the Benefits and Drawbacks of Becoming a Dental Hygienist?
When considering a new career path, it's important to weigh the pros and cons of the profession in order to make sure you understand all of the reasons for and against your decision. Here are some common benefits and drawbacks of a career in dental hygiene:
Benefits
- Flexible hours—One of the major draws to this field is the flexible nature of the work. As mentioned above, fewer than 40 percent of all dental hygienists work full time, with most only working a few days each week. This fact alone makes dental hygiene a very popular career choice for those with families, especially parents who want the ability to spend more time at home.
- A social work environment—Becoming a dental hygienist can be an excellent choice if you would enjoy working closely with others, including dentists, dental assistants, and patients. Additionally, as you build a practice over a long period of time, you can develop relationships with patients.
- The chance to help others—As a dental hygienist, you will be responsible for front-line dental care. You will not only be cleaning teeth but also delivering important care and education that can contribute to your patients' improved health. Plus, you can help make their visits a pleasant experience by providing your services in a kind and compassionate manner.
- Varied surroundings—Many dental hygienists work on a contract basis, allowing them to spend time in a variety of offices. If you choose this route, you could be working with a wide range of different health and dental professionals, as well as patients.
- Strong demand for your services—The outlook for a career in dental hygiene is expected to be very good in the coming years thanks to the many reasons mentioned previously.
- Fascinating work—A career as a dental hygienist means that you will be working in a field that is both fascinating and continually advancing, especially when it comes to preventive care and connecting oral health with overall well-being.
- Contracting benefits—As a contractor, you could enjoy the opportunity to choose which clients you take on, what days you work, and more. You could also negotiate items such whether your pay structure is hourly, daily, or commission-based.
Drawbacks
- Sitting for long periods—Due to the necessity of spending long stretches of time bent over while cleaning teeth, many dental hygienists experience neck and back pain. However, there are measures you can take to ensure you exhibit good posture, such as sitting in an ergonomically correct chair.
- Patients in pain or distress—Not everyone enjoys going to the dentist. This means that you may have to perform cleanings and examinations on individuals who are in pain or are experiencing anxiety.
- Small spaces to work in—While cleaning teeth or performing other procedures, you will be working in someone's mouth, which doesn't leave you much room. As a dental hygienist, you will need to hone your ability to navigate this small space using precision.
- Instability of contract work—If you become a contract dental hygienist, you will have to deal with things like patients cancelling without notice, meaning you won't be paid for no-show appointments.
- A large gender gap—According to the American Dental Hygienists' Association (ADHA), 97 percent of dental hygienists are female. So if you are a male thinking about entering this field, you might be the exception.
- Potential health hazards—As a dental hygienist, you could be working with individuals in all states of health, meaning there can be a risk of infection through airborne or blood-borne pathogens. However, this risk can be minimized through stringent safety measures and infection control practices.
- Chemical exposure—Dental offices are home to a variety of chemicals and irritants, such as silica dust, anesthetic gas, and beryllium, which can cause health problems. But, by following safety practices and procedures, this risk can be controlled.
- The smell of bad breath and the sight of tooth decay—Since you'll be working in patients' mouths, it's safe to assume you will be coming into contact with bad breath, rotten teeth, and even food, which can be a little gross.
