The current attendance fee at the National Dental Centre Singapore is $121 per visit, as in private dental clinics the price may be different. This includes a basic examination and diagnosis. Some further procedures and interventions will cost more, but the final price depends on the urgent treatment that you need. On average, going to a 24-hour dental centre will cost slightly more as it requires to have dentists on call to be able to treat patients without an appointment at all hours of the day.
