HOPE worldwide operates three social enterprise dental clinics in Sham Shui Po, Kwai Fong and Prince Edward. Starting from 2019, we go to elderly centers and community centers to provide dental examinations and oral hygiene education for grassroots elders and families. Most elderly centers participate in our dental check-up event every year. The evaluation of the event found that 65% of the elderly started to establish the habit of going to the dental clinic for teeth cleaning every year after participating in the dental check-up event, so that they can maintain oral health and reduce the risk of tooth decay and high dental surgery expenses.
