Can saliva predict cavities before they happen?
Decay is a process, not an event. A saliva test shows which children are heading for trouble - while it's still reversible.
A cavity that a dentist can see is the end of a long story. Weeks and months earlier, the balance of germs in the mouth shifted, the saliva's ability to neutralise acid weakened, and enamel quietly began to lose minerals.
What saliva can tell us
- Streptococcus mutans and Lactobacillus levels - the germs most closely linked to decay.
- Buffer capacity - how quickly saliva neutralises acid after a sugary snack.
- Combined with a diet and habits questionnaire, this gives a cavity risk score rather than a count of holes already there.
Why that matters for children
Two children with no visible cavities can have very different futures. A child at high risk may benefit from more frequent fluoride varnish, sealants, a stricter snack plan and earlier recall visits. A low-risk child may need nothing extra.
Cavity Wizard is building India's salivary caries-risk test. Ask in a consult whether your child would benefit from one.
