NHS: Dentist check-ups cut a worry for patients
Most adults in Wales will now be invited to visit the dentist only once a year instead of every six months.
That has worried some patients who said "it was very reassuring" to go twice a year.
Wales' new chief dental officer, Andrew Dickenson, said improvements in oral health mean seeing a dentist that often is "outdated".
Prof Dickenson said the change will allow practices to take on up to 112,000 new NHS patients a year.
But the British Dental Association (BDA) said his claims "look like they've been cobbled together on the back of an envelope".
