Good oral health is about more than your teeth and gums — it can impact your entire body. In fact, research suggests that periodontal disease may play a role in many health problems that affect people over 50, including cardiovascular disease, type 2 diabetes, rheumatoid arthritis, inflammatory bowel disease, Alzheimer’s and other forms of dementia, and even some cancers. It may all be tied to the body’s response to chronic inflammation.

Want to make sure you’re preserving your chompers as well as your overall health? Read our Smart Guide to Oral Health, then take this quiz to test your knowledge of what you’ve learned. 

Question 1 of 10

How often does the American Dental Association (ADA) recommend that you brush your teeth?

The ADA recommends brushing with fluoride toothpaste for two minutes at least twice a day, ideally before breakfast and before bed. This helps remove plaque, bacteria and food particles without over-brushing or harming the enamel.

Question 2 of 10

At what angle should you hold your toothbrush while brushing?

Holding your brush at a 45-degree angle allows the bristles to reach the gumline more effectively, which helps remove plaque and bacteria without irritating the gums.

Question 3 of 10

If your gums bleed when you floss, what should you do?

Bleeding gums usually indicate inflammation from plaque buildup. Rather than stopping, you should increase flossing frequency and effectiveness to reduce inflammation and improve your gum health over time.

Question 4 of 10

Why should you wait 30 minutes after eating acidic foods before brushing your teeth?

Brushing too soon after consuming acidic foods or drinks can damage the tooth enamel while it’s temporarily softened. Waiting 30 minutes gives time for remineralization, which helps protect your teeth.

Question 5 of 10

Which tool is not as effective as traditional string floss?

While better than not flossing, floss picks are less effective because they don’t wrap around each tooth; they could also spread bacteria between teeth. String floss is preferred for reaching the grooves along the gumline.

Question 6 of 10

What is one benefit of using an electric toothbrush over a manual one?

Electric toothbrushes, especially high-quality, rechargeable models, generate bristle movements that create microbubbles. These can help clean even beyond where the bristles touch, improving plaque removal.

Question 7 of 10

Which of the following is not a recommended mouthwash ingredient?

Alcohol-based mouthwashes can dry the mouth and kill beneficial bacteria. Instead, dentists recommend alcohol-free rinses containing fluoride and CPC, which target harmful bacteria and help strengthen teeth.

Question 8 of 10

Why should toothpaste not be stored in a clear pump dispenser?

Toothpaste in clear containers can degrade when exposed to UV light. This weakens preservatives, may reduce fluoride’s effectiveness and could potentially lead to bacterial growth.

Question 9 of 10

What should you do if you experience tooth sensitivity to hot or cold foods?

Tooth sensitivity can be caused by worn enamel, exposed roots, cavities or gum disease. Dentists may recommend sensitivity toothpaste, fluoride treatments or even bonding resin, depending on the cause.

Question 10 of 10

Which lifestyle habit has the strongest link to oral cancers and gum disease?

Smoking and tobacco use are major risk factors for gum disease and oral cancers. Smokers are up to 10 times more likely to develop oral cancer and often suffer more severe gum deterioration and tooth loss over time.
