Around 2,100 people attended dental hospitals in Cork and Dublin for a free check-up today as part of a campaign aimed at raising awareness of certain types of cancer.
"Due to the huge public response, the hospitals were unable to see a further 1,000 people who will be directly invited to attend for a checkup shortly," organisers of Mouth, Head and Neck Cancer Awareness Day said.
An analysis of the checkups will be available over the coming weeks.
Mouth, head and neck cancers are largely preventable as the two major risk factors are consumption of tobacco and alcohol.
On an ongoing basis people are being encouraged to contact their dentist or GP if they have any concerns.
