Oral Microbiome: The Key to Oral Health
Did you know...
-
The mouth can host 700 types of bacteria, fungi, viruses, archaea, and protozoans.
-
The average person has around 250 species from a pool of around 700 documented oral residents.
-
The only part of the body that has more microbiota is the gut
-
53% of the microflora have not been formally identified
-
Your mouth is the first line of defense against viruses and infections.
What is the oral microbiome?
Microbiome refers to the complex ecosystem that exists in our teeth, gums and mouth. It refers not just to bacteria, but also yeasts, fungi and viruses. It sounds alarming, but if managed well then this tiny microsystem works symbiotically with the body to promote both health and wellbeing.
Oral microbiome bacteria develop from birth
The community of microorganisms begins to form pretty much from birth. It experiences surges in activity when a new tooth breaks through. Microparticles from food, drink and even in the air we breathe, find an ideal environment in the mouth to thrive and flourish.
Oral microbiome in health and disease
The role of oral microbiome in health and disease prevention is an important one. Gum disease, tooth decay and bad breath can all be prevented by paying attention to oral care.
The microbiome system in the mouth is one of the most complex and diverse in the whole of the body. The mouth acts as a gateway to the whole body. As such a healthy microbiome is the first line of defense against harmful bacteria in foods, air, water, and airborne disease.
Oral microbiome and cancer
Studies as early as the 1950s showed a correlation between periodontitis and leukemia. However, more recent studies have shown a link to various other cancers that can be affected by oral microbiome. Whilst this does sound alarming, there is a positive aspect to this. Research into the link between oral microbiome and cancer is identifying bacteria, fungi and protozoans that actually help to fight cancers.
How to improve your Oral Microbiome
Oral microbiome can be controlled by good oral health habits, balanced diet and self-care. Likewise, stress, some medication and genetics can sometimes work against maintaining a healthy oral microbiome.
- Maintain good oral hygiene through brushing and flossing to remove plaque and harmful bacteria
- Avoid harsh alcohol based mouthwashes that can disrupt the balance of beneficial bacteria
- Rinse with a probiotic mouthwash
- Reduce sugar intake which feeds the harmful bacteria
- Avoid smoking and drinking
- Keep saliva flowing through chewing gum and staying hydrated
- Avoid mouth breathing that can dry out your mouth
- Eat a microbiome friendly diet with plenty of fibre rich foods
Maintaining oral health and overall health and wellbeing is more than just maintaining a good oral hygiene. It's important to consider all of our lifestyle choices and environment when working to restore balance within our mouths.
However, choosing oral care products that work in harmony with the beneficial bacteria is crucial for maintaining the right balance.

from 1654 reviewsGreat product , after 14 days , teeth are no longer sensitive and the annoying coffee stains are practically gone ! Really impressed with this product and a great taste

Ordered a few times now and will continue to, we love truthpaste

Really good toothpaste, excellent product.

It took a little while for me to get used to the neem oil as I use it in my garden for pest control and don’t like the smell… anyway, after a week of everyday use, I don’t even notice it anymore. Wonderful toothpaste which leaves my mouth feeling fresh all day with the added bonus of knowing it’s natural ingredients! Thanks Truthpaste!! I think I’ll be a lifelong fan!!!

Brilliant. Doesn’t foam (thank goodness) doesn’t taste of mint (phew!) and isn’t sweet except for a faint, natural warmth with a hint of sweetness. Leaves my teeth and gums very clean and comfortable, and takes very little of the product to do so - thank you

If you want whiter teeth, if you want healthier teeth and if you don’t want chemicals then get it I been using it for 18 months now and it’s the best I’ve ever used, recently changed the favour from fennel to mint and the mouthwash is incredible. Don’t question buying it.

Mouth feels so much better after using this, thought I’d try it as don’t like using fluoride and this has a better feel all round give it a try 100% Heathy option

I love this mouthwash.

At last, toothpaste that doesn’t strip all the skin from inside my mouth

This new toothpaste has a great fresh minty taste, cleans thoroughly, and apparently rejuvenates the enamel as it goes... no more sensitivity to, or the need for, fluoride and harsh chemicals of normal toothpaste... my mouth and gums are finally happy...

I love the paste of this wonderful toothpaste. Leaves you with fresh breath. Natural.

I absolutely love this toothpaste! It has a great consistency and a refreshing taste. After using it, my teeth feel as clean and polished as they would after a visit to the dentist.
