If an existing part of a denture such as a clasp, tooth, or flange is broken and replaced or repaired, this is a 'Repair of a denture' which is free of charge to the patient irrespective of the charge paying status.
There is no time restriction to how long after the original appliance was made for a repair to be given.
If there is an open Course of Treatment (CoT), the denture repair would be expected to be claimed as part of this CoT.
If there's no open CoT, a new FP17 claim can be submitted with 'Repair of a denture'. This will award 1 Unit of Dental Activity (UDA).
