I agree that dental treatment can be very expensive. I imagine a dentist would argue that they have spent a lot of time and money, and hard work on their qualifications and dental materials and equipment are very expensive to buy. My best suggestion to anyone looking for affordable dental care would be to contact dental schools in your area. Appointments will take longer but students are closely supervised. There may well be a charge for treatment but costs will be lower. Dental tourism might be worth considering, but bear in mind that if anything goes wrong then you may have trouble getting it put right.
