NHS dental charges in England are based on the course of treatment you need rather than the number of appointments required to complete it.
If your treatment includes procedures from more than one band, you normally pay the charge for the highest band included in that course of care. Some patients are entitled to free NHS dental treatment or help with dental costs 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, while Band 3 covers more complex restorative treatment such as crowns, bridges and dentures.
