NHS dental charges are based on the level of treatment required for each complete course of care. You normally pay one charge for the course, even when treatment requires more than one appointment.
If treatment from different bands is needed within the same course, the highest applicable band determines the charge. Some patients may qualify for free NHS dental treatment or help with the cost depending on their circumstances. Band 1 covers assessment, diagnosis and preventive care. Band 2 includes additional treatment such as fillings, root canal treatment and extractions. Band 3 covers more complex restorative treatment including crowns, bridges and dentures.
