With the mouth being the first meeting place between the outside environment and our immune systems, an in-depth understanding of the oral microbiome is key to our health and well-being. DrBonnie360 sheds light on the latest oral microbiome research, and highlights novel oral care products to help balance the oral microbiome. As DrBonnie360 says, better oral health is better overall health. Topics Include: The Ecological Plaque Hypothesis of Decay and Periodontal Disease Oral Health and its Connection to Cardiovascular, Alzheimers, and other Autoimmune Diseases What Can We Do: Food and Lifestyle Modification What’s New in Oral Well-being?

1. ORAL
MICROBIOME
EXPLORATION
@DrBonnie360

2. Imbalance of the oral microbiome can
lead to development of oral diseases
such as periodontal disease.
DISEASE
STEP 1
When vascular oral mucosal barriers are
disturbed, oral bacteria can enter the
bloodstream.
DISRUPTION
STEP 2
PENETRATION
STEP 3
Oral bacteria in the brain can trigger
inflammatory responses, resulting in
buildup of amyloid plaques.
BUILD-UP
STEP 4
Oral pathogens in the bloodstream can
penetrate the blood-brain barrier during
inflammation or in times of stress.
CAN ORAL DISEASES CAUSE ALZHEIMER’S?
Recent research has suggested that oral pathogen P.gingivalis, a key contributor
to gum disease, may play a role in Alzheimer’s Disease development.

3. If oral pathogens in the bloodstream are able to cause
inflammation and plaque build-up in the brain, then it is possible
for misplaced oral bacteria to trigger inflammation in areas of the
body that are further removed from the mouth, inducing
inflammatory diseases such as chronic or autoimmune diseases.

4. ORAL CAVITY ANATOMY

5. There are 700 different
species of bacteria that
live in different
microbial sub-habitats:
teeth, tongue, gums,
saliva, ear nose and
throat.

7. The oral microbiome is influenced by
numerous factors that alter the
composition of the microbes that
inhabit the mouth.

8. BALANCE IMBALANCE
A BALANCING ACT
A balanced oral microbiome is characterized by a healthy
diet, plaque control, and good oral hygiene.
Imbalance of the oral microbiome is influenced by a poor
diet, inadequate plaque control, lifestyle risk factors, and bad
oral hygiene.

between the outside
environment and our
immune systems.

17. Oral vascularization
allows bad bacteria
to travel to other
parts of the body.

18. Exercise activates
immune system and
reduces inflammatory
cytokines
Proper diet and choice of
foods can help maintain the
balance of the oral
microbiome
FOOD
Night eating leads to
increased dental
plaque and gingival
inflammation
Research shows that timing
of eating and exercise may
help to reduce oral
inflammation
LIFESTYLE
Water
normalizes the
pH of your
mouth
High pH foods
(>7) help to

foods
WHAT CAN WE DO?
Drink more water &
eat alkaline foods
Eat during the day &
increase exercise
