Diet & the Oral Microbiome
How eating patterns, sugars, hydration and routine oral care interact with the environment of the mouth.
The oral environment changes throughout the day. Diet, saliva, hygiene, tobacco exposure, medications and dental disease can all influence conditions in the mouth. No supplement cancels out frequent sugar exposure or inadequate oral hygiene.
Useful priorities
| Area | Practical focus |
|---|---|
| Added sugars | Frequency matters for tooth-decay risk. |
| Hydration | Supports normal saliva function. |
| Oral hygiene | Brush with fluoride toothpaste and clean between teeth as advised. |
| Persistent symptoms | Seek dental evaluation rather than relying on supplements. |
