Cafodd Cynllun Gwên ei sefydlu a’i ariannu gan Lywodraeth Cymru i dargedu plant yn benodol mewn ardaloedd lle’r oedd y lefelau pydredd dannedd ar eu huchaf i fynd i’r afael ag anghydraddoldeb mewn clefydau deintyddol. Mae’r weledigaeth o ran ystyried y materion hyn yn yr hirdymor wedi talu ar ei ganfed, ac mae’r rhaglen yn profi’n llwyddiant ysgubol.
Designed to Smile was set up and funded by Welsh Government to specifically target children in areas where levels of tooth decay were highest to address inequality in dental disease. The foresight in taking a long-term view of the issues has paid dividends, and the programme is proving to be a significant success.
