Plaque — bacterial buildup that resides in sticky stuff on your teeth — causes decay and can lead to periodontal disease, which inflames gums and destroys supporting tissues such as ligaments and bones. And with their demise can come loose — and eventually lost — teeth

Poor oral hygiene and lack of professional care are big contributors

Other factors that put you at greater risk for periodontal disease and potential tooth loss include

Smoking

Poor nutrition

Diabetes

Hypertension

Arthritis

Changing hormones during pregnancy can also affect a woman’s response to disease. So it’s especially important to get regular professional care throughout pregnancy

People with developmental and other disabilities are at greater risk as well, due to the challenges of home care. This means caregivers need to be creative about helping with this task

Early onset of periodontal disease is another concern. “If I see a patient under 40 with periodontal disease, that’s worrisome to me because I know this person will be particularly susceptible,” says Donald S. Clem III, DDS, a periodontist in Fullerton, Calif., and the 2010-2011 president of the American Academy of Periodontology

Brush and Floss

First, wash your hands. Brush twice a day with a soft-bristled toothbrush and floss once a day

“You wouldn’t have to floss if you could reach all the parts of your mouth with a toothbrush, but you can’t — no more than you can vacuum a whole house without certain attachments for getting into corners,” Price says. If you don’t know how, ask your hygienist or dentist

Other tips to prevent bacterial growth

Use a toothpaste that contains fluoride

Wash your toothbrush once in a while in the dishwasher or place it in a cup of mouthwash

Let your toothbrush dry completely after each brushing

Don’t share your toothbrush with anyone
