Market challenge


Oral health challenges and dental cavities affect a large number of people worldwide and are substantially caused by a lack of sufficient oral hygiene combined with certain diet and lifestyle choices. They are particularly prevalent in developed countries such as the US and Europe, often due to high sugar consumption. According to the World Health Organization (WHO), dental cavities have risen to be the number 1 non-transferable condition in the world.1

Dental cavities are the result of plaque forming on the surface of the teeth. Acid-producing bacteria can adhere to the plaque, converting some of the sugars in food and drinks into acids that break down the tooth over time. The global oral health care market is growing and expected to continue its growth journey.



Children, teens with braces, and the elderly are at higher risk of oral health conditions 

People of all ages can get dental cavities, but some groups have a higher risk of developing cavities than others.1

  • More than 60% of schoolchildren around the world experience dental cavities at some point4
  • Thinner enamel and less mineralization in primary teeth put children at higher risk for dental cavities5, 6
  • Wearing braces increases plaque levels by up to three times compared to people not wearing braces, indicating a higher risk of cavities7
  • 27% of adults in the United States have an unattended tooth condition8 
  • Dental root exposal as well as reduced salvia production promotes the occurrence of dental cavities. These are common in the elderly population, increasing their risk of developing dental cavities9, 10
