Private dental patients in the UK are navigating a "broken" complaints system that leaves them with little protection when treatment goes wrong, according to consumer group Which?. A survey of 1,009 patients who had experienced problems found that 39% felt costs were excessive, 22% paid more than quoted, and 16% reported feeling pressured into specific treatments — painting a picture of an industry where transparency and accountability are sorely lacking.

The complaints pathway itself is a major sticking point. Most patients (62%) didn't even bother complaining to their practice, fearing it would damage their relationship with their dentist or simply believing nothing would change. Of those who did complain, nearly half received only a verbal apology with no financial or clinical resolution. The Dental Complaints Service — the next step in the process — cannot award compensation or make binding decisions, leaving patients in a regulatory no-man's land.

By the Numbers:

• 39% of surveyed patients felt costs were excessive
• 22% paid more than originally quoted
• 26% were dissatisfied with treatment quality
• 10% reported a direct clinical mistake
• Only 9% escalated complaints to the Dental Complaints Service
• 63% of those who didn't escalate said further action felt pointless

Why it matters: Which? is urging the government and regulators to establish a mandatory independent ombudsman for private dentistry — one with real teeth. The Competition and Markets Authority has already launched a market study into private dental services, signaling growing scrutiny of an industry that has expanded rapidly as NHS dentistry continues to struggle with chronic underfunding.
