A dentist says he feels "strangled" by NHS contracts and believes NHS dentists may not exist in two years' time.
Dr Harj Singhrao, who has a practice in Newbridge, Caerphilly, said money was allocated on a "one size fits all basis" meaning in high need areas like his, he had to lose money in order to provide good care.
It comes as the British Dental Association (BDA) Cymru published an open letter accusing the Welsh government of "peddling half- truths", adding more practices were looking to hand NHS contracts back.
The Welsh government said: "We are working to ensure the NHS dental contract is fairer for patients and to the dental profession."
