What Is a Dental Hygienist and Why Are They Important?

Batman to Robin: “You owe your life to dental hygiene.” Batman (1966, TV series)

This may have been scripted banter between the two characters, but it is not too far from the truth!

Studies have shown that poor oral hygiene is linked to heart disease, diabetes, oral problems during pregnancy, and erectile dysfunction.

The most apparent manifestation of poor oral hygiene is gingivitis (inflammation of the gum) and periodontitis (inflammation affecting the tissues that support the teeth). Periodontitis can even cause you to lose your adult teeth.

But is that all?

Nope! A University of Florida study revealed the presence of live periodontal bacteria in human atherosclerotic tissue, which means, there is a strong association between the development of blockages in the arteries and gum disease.

As you can see, dental hygiene isn’t to be taken lightly.

Thankfully, there are specialized professionals dedicated to preventive oral health – your friendly neighborhood Dental Hygienist!

So, what do Dental Hygienists do? They Assess, Prevent and Educate.

Assess what? Dental hygienists assess your oral health by conducting thorough examinations of your teeth and gums. They look for signs of gingivitis, cavities, gum recession, and other potential issues. They may use tools like X-rays to detect problems beneath the surface, ensuring nothing is missed. By identifying these concerns early, they help prevent small issues from becoming big, costly problems.

Prevent? That’s their specialty! Dental hygienists are skilled in performing professional cleanings, removing plaque and tartar buildup that your toothbrush simply can’t tackle. This helps reduce the risk of gum disease and cavities. They also apply treatments like fluoride and dental sealants to strengthen teeth and provide extra protection against decay.

Educate? Absolutely. A significant part of a dental hygienist’s role is empowering you to maintain excellent oral health between visits. They teach proper brushing and flossing techniques, recommend products tailored to your needs, and offer tips for keeping your smile healthy. Many also educate patients about how oral health impacts overall well-being, emphasizing the connection between the mouth and the rest of the body.

So, the next time you’re in the dentist’s chair, remember to thank your dental hygienist for being the unsung hero of your oral and overall health.
