Overview

Summary of dataset and variables

This StatsWales cube presents data for adults and children treated by gender and local health board, for each 24-month period ending March for adults and each 12-month period ending March for children.

Data collection or calculation

Statistics are based on patients treated at dental practices in Wales. This means that this data includes non-Welsh residents treated in Wales but does not include Welsh residents treated outside of Wales. This is because Welsh Government has access to FP17W data from dental practices in Wales only.

A separate FP17W level dataset, supplied by NHS Business Services Authority, is used to derive counts of patients treated by patient characteristics. Totals derived from this dataset are higher than the equivalent headline figures published on StatsWales: Adults treated at Welsh dental practices over the last 24 months and Children treated at Welsh dental practices over the last 12 months because patients whose most recent treatment within a reference period took place in England, but who also received earlier treatment in Wales during that period, are excluded from the headline measures but retained in the FP17W‑level dataset. At Wales level, counts for adults treated over the last 24 months are no more than 0.9% higher, while counts for children treated over the last 12 months are no more than 4.3% higher.

The percentage of the population treated in each 24-month and 12-month period are calculated using the mid-year population estimates from the Office for National Statistics (ONS). The ONS revised the estimates for mid-2022 and mid-2023 on 30 July 2025, and therefore statistics for the percentage of the population treated have been revised. This has resulted in small changes ranging between 0.1 and 0.5 percentage points at Wales level.

Data only available for the financial year ending in March 2022 onwards. As the adult measure is based on a 24-month reference period, the first year of available data is the 24-months ending March 2023.

The National Institute for Health and Care Excellence (NICE) recommends that adults are recalled for dental check-ups at intervals of three months to 24 months depending on the individual’s oral health status. The guidance also recommends that the longest recall period for children (aged under 18) is no longer than 12 months. Therefore, statistics on adults treated are based on the previous 24-month period; statistics for children refer to the previous 12-month period.

Each patient is counted only once even if they have received multiple episodes of care during the reference period.
