Eligibility for NHS dental care can depend on various factors, including your age, income, and immigration status. Children under the age of 18 are usually eligible for free NHS dental treatment. Adults may have to pay for some services, but those on certain benefits or low incomes might qualify for reduced fees or free treatment. If you're unsure about your eligibility, it's best to check with your local NHS dentist. They can provide specific information regarding what treatments are available to you based on your circumstances.
