Cyflwynir mwyafrif y mynediad at wasanaethau deintyddol yng Nghymru mewn lleoliadau gofal sylfaenol gan gontractwyr annibynnol – ymarferwyr deintyddol ar y ‘stryd fawr’ gyda chontractau’r GIG. Mae system contractau deintyddol y GIG wedi’i seilio ar ddarparu triniaeth cam hwyrach. Nid yw’n cael ei harwain gan anghenion na’i mesur ar sail canlyniadau. Mae hyn yn golygu nad oes cymhelliant ariannol arwyddocaol ar hyn o bryd i ddeintyddion ganolbwyntio ar atal – i newid i ofal ataliol, defnyddio sgiliau’r tîm cyfan a ‘mynediad’ agored oddi mewn i’r system bresennol.
The majority of access to dental services in Wales is delivered in a primary care setting by independent contractors -‘high street’ dental practitioners holding NHS contracts. The NHS dental contractual system has been built around providing later-stage treatment. It is not needs led or outcome measured. This means there is currently no significant financial incentive for dentists to focus on prevention - to shift to preventive care, make use of the  skills of the whole team and open ‘access’ within the current system.
