Carbohydrates and Dental Health

  • Dental caries is associated with acid production from bacterial fermentation of carbohydrates
  • Isomaltulose is tooth-friendly and non-cariogenic
  • Isomaltulose is not readily fermented by oral bacteria
  • Its consumption does not cause the plaque pH drop associated with enamel demineralization
  • Tooth-friendly properties have been demonstrated in dental plaque pH studies

What makes a carbohydrate tooth-friendly?

A carbohydrate is considered tooth-friendly when oral bacteria do not readily ferment it to acids that lower dental plaque pH. Unlike sucrose, isomaltulose is only minimally fermented by oral bacteria and therefore produces little acid in dental plaque.

As a result, isomaltulose does not cause the critical plaque pH drop associated with enamel demineralization and dental caries.

Non-cariogenic properties of isomaltulose

The non-cariogenic properties of isomaltulose have been demonstrated in laboratory studies and confirmed in human dental plaque pH telemetry studies. Unlike sucrose, isomaltulose is not readily utilized by acid-producing oral bacteria, including Streptococcus mutans.

Consequently, plaque pH remains above the level associated with enamel demineralization, supporting the classification of isomaltulose as a non-cariogenic carbohydrate.

Relevance for nutrition and product formulation

The non-cariogenic properties of isomaltulose make it a tooth-friendly carbohydrate for foods and beverages where dental health and carbohydrate energy are both relevant. Applications include drinks, snacks, functional foods, and products intended for between-meal consumption. Isomaltulose combines mild sweetness and fully available carbohydrate energy with a tooth-friendly profile.

Conclusion

Isomaltulose is a tooth-friendly, non-cariogenic carbohydrate that is not readily fermented by oral bacteria. Unlike sucrose, it produces little acid in dental plaque and does not cause the plaque pH drop associated with enamel demineralization. These properties make isomaltulose a relevant carbohydrate choice for foods and beverages designed with dental health in mind
