Qualification for dental benefit is based on satisfying certain PRSI conditions, which vary depending on the age of the person concerned. In this case, the person concerned would need to have paid 260 PRSI contributions at Class A, E, H, P or S, since first starting work, and also have at least 39 qualifying contributions paid at the correct rate, or credited, in the relevant tax year/s on which the claim is based.
While she has 260 PRSI contributions paid since first starting work, she does not have 39 contributions paid or credited in any year between 2013 and 2016; the relevant the tax years on which the current eligibility check is based. As a result, she does not qualify for dental benefit at this time.
However, if the customer has a Medical Card, she should contact her local HSE office, who will be able to advise her on her entitlements under the HSE scheme.
I trust this clarifies the matter for the Deputy.
