Patients expect the price on a treatment plan to be the absolute final price for their treatment, which makes perfect sense from their point of view. After all, when I get a bill for an amount, I expect to be paying that amount and not anything less or more. So when going to a private dentist, and paying for a service, should you not expect this same kind of pricing? What are all of these “hidden fees” anyway?
Please consider the following scenario: when asking for the price of an extraction, the dentist gives you a price. Upon consultation, they notice that the tooth next to the one you want to get extracted also needs work done, or it may not survive the extraction itself. You also did not think about replacing the tooth you extracted, because you are not a medical professional, but extraction will cause the loss of the adjacent teeth as well. So to keep your teeth in your mouth, which is the job of the dentist, your bill just went up significantly. This is why “hidden fees” exist, because medical science is not an exact science, and each case, and each mouth, is different, and many times these differences only make themselves apparent once the procedure is already underway.
All of the issues should become apparent at a consultation session, after a panoramic dental x-ray. It may still be the case that certain things are not, and they come up during the procedure you have chosen for yourself, but you should be well aware of it ahead of time.
