Why does it matter?
Practice accreditation is not mandatory for private dental clinics. If the dental practice you attend undergone practice accreditation, it means that they have done so voluntarily at their own expense and time, committed to continuously improve safety and quality for patients.
Not every dental practice is accredited, so if your dentist hasn't done so yet, there's no need to worry. All dental practices must comply with many legislative guidelines, standards and requirements even without accreditation.
However, because practice accreditation involves a continual assessment and improvement of practice procedures, the ADA encourages its members to have their practices accredited.
