Sir, health education is fundamental for oral disease prevention and oral health promotion. However, most individuals and communities have been facing serious obstacles for accessing primary oral healthcare as well as oral health education around the world.

After experiencing different technologies such as virtual reality, augmented reality, artificial intelligence and 3D internet, we are hearing about Metaverse, which is an extension of the internet and allows interaction between users and their environment. Oral health education and conversations can be provided virtually to target groups and communities through Metaverse software by either public or private health sectors for public benefits.1 There are no travel costs, no limit to the number of participants; and it can educate different target groups, delivering different sessions from anywhere in the world. All these can provide the highest accessibility for oral health education for schoolchildren, teachers and caregivers.2,3

Nonetheless, we are aware that digital advertising is a major global business, promoting unhealthy habits and products. Therefore, governments and policymakers are urged to enact restrictive policies for unhealthy foods and habits, especially alcoholic beverages and tobacco product advertisements, on the Metaverse platform. These are all serious risk factors for non-communicable diseases. The Metaverse platform is expected to promote oral health, healthy lifestyle and wellbeing as well as preserving health equity as core values.3
