Oral Health the Functional Medicine Way
We all recognize the importance of maintaining good oral health, but its significance goes far beyond just a bright smile. Numerous studies have demonstrated a clear connection between oral health and overall wellness, particularly heart health, as poor dental hygiene has been linked to an increased risk of cardiovascular issues. The mouth serves as the entry point to our gastrointestinal system, making the care of our teeth, gums, and oral tissues vital for promoting optimal gut health. Neglecting oral hygiene can lead to imbalances that affect digestion and the body’s microbiome. Beyond these systemic benefits, maintaining a healthy smile is something we all strive for, and with only one set of adult teeth to last a lifetime, taking proper care of them is essential for long-term health and confidence.
Oil pulling—what does the research say?
Oil pulling, an ancient Ayurvedic practice, involves swishing oil (typically coconut, sesame, or sunflower oil) in the mouth for about 15-20 minutes.
Several studies have shown that oil pulling can help reduce plaque and gingivitis. A study published in the Journal of Clinical and Diagnostic Research found that oil pulling with sesame oil was effective in reducing plaque and gingivitis levels, with results comparable to chlorhexidine mouthwash.
It’s believed that the swishing action of oil pulling helps to mechanically reduce bacteria and debris in the mouth. The oil may also have a saponification effect (like soap), which helps remove plaque-forming bacteria.
Some studies suggest that oil pulling may reduce the amount of harmful bacteria in the mouth. Coconut oil, which contains lauric acid, is thought to have antimicrobial properties that can reduce the growth of Streptococcus mutans, a bacterium involved in tooth decay.
Research indicates that oil pulling may help reduce bad breath. A study published in the Journal of Natural Science, Biology, and Medicine found that participants who used oil pulling had reduced levels of odor-causing compounds (volatile sulfur compounds) similar to those who used mouthwash.
There is very little scientific evidence to support the idea that oil pulling can significantly whiten teeth. Anecdotally, some people report a brighter smile after regular oil pulling, but this is likely due to the removal of surface stains rather than a whitening effect on tooth enamel.
My advice is to use oil pulling as an adjunct to regular brushing and flossing. I like using the brand Desert Essence daily when I am in the shower. Be sure to spit out the oil afterwards in the waste basket so it doesn’t gunk up your pipes. Never swallow it.
Tongue scraping
Tongue scraping, the practice of using a tool to clean the surface of the tongue, has been a part of Ayurvedic and traditional medicine for centuries. It's gaining popularity in modern oral hygiene for its potential benefits in reducing bad breath and improving oral health. The back of the tongue is a primary site for the accumulation of bacteria and debris, including food particles and dead cells, which can produce malodorous compounds. Tongue scraping helps physically remove this coating and reduces the bacterial load that contributes to bad breath.
Tongue scraping has been shown to be effective in reducing bad breath. A study published in Journal of Periodontology found that tongue cleaning with a scraper reduced volatile sulfur compounds (VSCs)—the main contributors to halitosis—significantly more than brushing alone.
Research shows that tongue scraping can reduce the microbial load in the mouth, particularly bacteria associated with bad breath, tooth decay, and gum disease. A study published in International Journal of Dental Hygiene indicated that regular tongue scraping significantly reduced the amount of Streptococcus mutans (a bacterium linked to cavities) in the mouth.
Tongue scraping has been found to be more effective than toothbrushing alone in removing bacteria and debris from the tongue. While brushing can clean the surface, the specialized design of a tongue scraper allows for more thorough removal.
Some evidence suggests that tongue scraping can enhance taste perception. A study published in Journal of Clinical Periodontology found that regular tongue cleaning improved taste sensitivity, particularly for bitter and salty tastes. By removing the coating on the tongue, taste buds are more exposed and functional.
Food particles and dead cells that accumulate on the tongue can impair taste sensitivity. Regular cleaning allows the taste buds to function optimally.
What about mouthwashes?
While mouthwashes may be recommended for certain periodontal conditions, usually they are meant to be used short-term. Gone are the days of alcohol-based Listerine type recommendations. In fact, frequent use of alcohol-based mouthwashes has raised concerns about the potential link between alcohol and oral cancer. While a direct causative relationship has not been definitively established, some studies suggest a correlation between high alcohol content mouthwash and oral cancer risk, especially in heavy drinkers or smokers. As a result, many people prefer alcohol-free formulations. Alcohol-based mouthwashes can also contribute to dry mouth, which may exacerbate oral health problems like cavities and gum disease.
If you prefer to use a mouthwash occasionally, I recommend the brand Natural Dentist which is an herbal/botanical mouthwash that is alcohol-free and SLS free. It also contains aloe vera to soothe and prevent bleeding gums.
Flossing
Other essential oral health practices include:
Flossing twice a day, in the morning and before bed. Be sure to choose non-toxic floss—I'm a fan of Burst, which uses a thicker, black thread. It's incredibly satisfying to see the soft plaque come off on the dark floss, and it has motivated me to become a more consistent flosser!
Using a soft-bristled electric toothbrush and brushing for two minutes, both in the morning and before bed, to ensure thorough cleaning.
Opting for a hydroxyapatite-based toothpaste, which helps strengthen enamel. I recommend Boka, and my favorite flavor is ElaMint. Boka’s formula is free of SLS and fluoride, making it a great choice for those concerned about fluoride overexposure.
Lastly, to maintain optimal oral health, find an excellent dentist and visit them at least twice a year. Dentists perform oral cancer screenings, assess your airway, and can evaluate alignment issues or TMJ (Temporomandibular Joint Dysfunction).
