Private dental charges
The cost of private dental treatment varies from dentist to dentist. Most dental practices are very transparent with their private treatment pricing so you should be able to look up the private treatment costs of your local dentist online. They will also be able to provide you with their prices in the practice.
On average, it's likely your private dental treatment will cost more than going through the NHS.
However, with private treatment, you will receive additional time with your dentist which they will spend looking at your mouth for early signs of oral health problems. They'll have more time to spend with you to discuss and improve your oral health routine as well.
