Want to Prevent Disease? Keep Your Mouth Clean

By Michael A. Smith, MD

When I was a young doctor completing a cardiovascular rotation at the University of Utah, Dr. Steven L. Miller, a research cardiologist at the university, discovered that bacteria from your mouth are the same bacteria found within unstable arterial plaques. The implication was huge.

For the first time, doctors started to think of your mouth as a tool for seeding vital organs with disease-causing bacteria. Soon there was an explosion of research confirming Dr. Miller’s initial discovery that bacteria from your mouth are associated with disease throughout your body.1

So what does all of this mean? Well, don’t forget to take care of your teeth and gums if living a healthy life is your goal. That may seem like a silly thing to say, but according the CDC, people generally aren’t taking good care of their mouths.

CDC: Poor Oral Hygiene is Common

The National Center for Health Statistics, a division of the CDC, prepared a report using data from the National Health and Nutrition Examination Survey from 2005 to 2008. Here are the report's key findings:

  • 20% of children aged 5 to 11 and 13% of teens between the ages of 12 and 19 had at least one untreated cavity.
  • 25% of adults between the ages of 20 and 44 had at least one untreated cavity.
  • 20% of adults over 65 had at least one untreated cavity.
  • 39% of children and 52% of teens had a dental restoration, such as a filling or root canal.
  • Restoration rates were nearly 90% for adults over 65.
And it’s not just cavities. The high acidic content of fruits juices and sports drinks, for instance, can erode enamel and allow for bacterial growth. Besides daily brushing and flossing, we wanted to discuss some nutrients for improving oral health.

CoQ10 is Good for Your Gums

The antioxidant CoQ10 aids energy production in the body. Research has found that people with gum disease are often significantly deficient in CoQ10.2 Initial evidence suggests that topical CoQ10 supplements may be effective in slowing gum disease by reducing bleeding and swelling.3

While additional research is needed, the consensus is that CoQ10 helps supply the energy needed for the body to heal and repair mouth tissue.

Xylitol Prevents Bacterial Growth

Pure xylitol is a white crystalline substance that resembles and tastes like sugar. It is found naturally in fruits such as plums, strawberries, and raspberries. Xylitol is used commercially to sweeten sugarless gum and candies.

It has 40% fewer calories than regular sugar and appears to have none of sugar’s negative effects on insulin release.4 It is also believed to prevent cavities by inhibiting the growth of cavity-causing bacteria such as Streptococcus mutans.5

A double-blind, placebo-controlled study of 2,630 children compared a standard fluoride toothpaste with one that also contained 10% xylitol. Over a three-year period, children given the xylitol-enriched toothpaste developed notably fewer cavities than those using the fluoride-only toothpaste.6

Lactoferrin Heals Mouth Ulcers

Lactoferrin, a naturally occurring antimicrobial agent, is found in saliva and gingival fluid, as well as in breast milk, tears, and other bodily fluids. Lactoferrin may bind to and slow the growth of periodontitis-associated bacteria.7 In an animal study, locally applied lactoferrin powder appeared to support the healing of oral lesions.8

Tea Tree Oil Eases Gum Inflammation

A recent study in the Australian Dental Journal showed that a toothpaste gel containing tea tree oil, used twice daily, reduces the presence of gingivitis compared to placebo.9 Tea tree oil’s anti-inflammatory and antimicrobial properties may be responsible for its effects in promoting oral health.

Squalene Promotes Healthy Cell Growth

Extracted from shark liver oil, squalene has been embraced for its antioxidant properties. Squalene has been used as an adjunct therapy in the management of some cancers. A recent study found high doses of squalene to be beneficial against bacterial, viral, and fungal infections.10

Are You Minding Your Mouth?

There are many ways to improve your health: eating a healthy diet, exercising regularly, and periodically visiting your doctor. Health-conscious adults should certainly add proper oral hygiene to this list of health fundamentals.

Oral hygiene is a simple way to improve your well-being today and greatly increase your chances of enjoying a healthy, disease-free future. Are you minding your mouth?

When talking to a dental student, I was surprised to hear that there are actually people that come into the clinic requesting to have all of their teeth pulled. The people that make this inquiry have a false notion that having their teeth taken out will mean that they don't have to work on their oral health any longer.

I am completely agree with your views, mouth cleaning is very important as it may cause many severe diseases. Usually people take it very light and they do not worry about oral hygiene. When talking about health we need to take care of all kinds of hygiene factors. Its very important.

Corium Direct - Agreed. Most people don't take oral hygiene very seriously but they should!
