Report 01 · Patient movement in Canadian dentistry

Why patients leave their dentist — and whether the next clinic actually does better

An analysis of 106,609 moves between Canadian dental clinics, where the same Google reviewer rated one clinic and then a different one nearby, including 10,345 that followed a bad review, and the complaints written on the way out.

For most, the next clinic was rated much better: 70.6% gave it 4 or 5 stars. But 27.8% left another 1 or 2-star review.

the unhappy-switch rate of clinics that reply to most of their Google reviews

Reasons come from reading all 8,654 reviews that unhappy switchers wrote, one by one, by AI readers working to a fixed list. How that was done is in “About this study” below.

How we counted a move: the same reviewer rated one clinic and then a different clinic within 24 months and 40 km. The full method and limitations are below.

01

Why they go

What unhappy switchers said on the way out, how quickly a new clinic appeared, and how far away it was.

Why they leave

Not the drill: failed work, the bill and how they were treated

Three complaints dominate, level with each other as the main one. Pain barely registers.

We read all 8,654 reviews that unhappy switchers wrote. As the main complaint, work that failed (20.4% of those with a clear reason), how people were treated (20.4%) and cost or a surprise bill (19.1%) are level. Counting every complaint a reviewer raises, how they were treated comes up most often, in 39% of reviews, then cost (34%) and failed work (26%). Pain during treatment is the main complaint in 3% and is raised in 7%.

How we know. Keyword rules first sorted these reviews, and they failed a blind check on 23 September 2026: their “practice closed” group, for example, was right 0 times in 30. So every one of the 8,654 reviews was read whole by an AI reader working to a fixed list of 13 reasons, without seeing any earlier label. 438 were read twice by separate readers, who agreed on the main reason 94% of the time, and we checked a random sample ourselves. A review can raise several complaints, so the percentages add up to more than 100.

In their words

Work that failed or had to be redone
Went for an extraction. Was a nightmare. He broke a second tooth. Bled all over the floor. He denied any problems. Had to see a specialist. They asked if I was in a car accident. Had to have reconstruction surgery. Still suffering years later. …

How they were treated
Never again. Didn’t even make it to the actual appointment. I was chastised the minute I walked in for wearin shoes (?). Then chastised because I didn’t confirm my appointment.

Cost or a surprise bill
Even though I have enhanced dental coverage, the expense code they submitted was not covered by my insurance provider. Which is understandable. But you being in business for so many years, why wouldn’t you do a pre-authorization and inform us of the cost upfront?

Waiting or cancelled appointments
I write this standing in front of their closed and locked door at the time I am supposed to be in for an appointment. The door is locked and no one answers if I knock.

Normally our visits are efficient and courteous in friendly environment. Not today. After driving through snowstorm, and my son missing school, we were turned away for being 11 minutes late!

I was not overly happy when the hygienist asked the dentist quietly if she should be using etch on the filling they just filled. It fell out the next day. They built the filling up too much and it broke again when I tried to eat.

Not listened to or not told
Been going here for longer than I can remember. Perhaps 20 years. The new doctors are terrible. I come in with a chipped tooth. I showed them the chipped tooth. I don’t know if it’s apathy or contempt, but they had the audacity to tell me I do not have a chipped tooth.

… I’ve never in my 61 years of going to a dentist have I ever been subjected to what I endured – I only wanted a cleaning – but was told I had to have a consult – after paying $400 – teeth still not cleaned.

A disabled or vulnerable patient treated poorly
Unfortunately, this was not a great experience for my daughter, who is neurodiverse. The environment upon arrival was very congested and chaotic, which immediately overwhelmed her. A quieter, more sensory-friendly setting would have been far more suitable.

Butchered my mouth. I had a wisdom tooth pulled and she didn’t freeze me properly, I was literally screaming as she removed the tooth, I felt everything!

This use to be a very professional, friendly practice. It is now owned by a corporation or a franchise. Nothing wrong with that except the people involved have no clue.

How long they wait

28 in 100 review a new clinic that same month

The median gap is four months, versus seven months across local moves overall.

Unhappy switchers move faster than the wider group: 28% review a new clinic in the same month as the bad review, and 49% have done so within three months. People sent elsewhere without being treated, and disabled or vulnerable patients treated poorly, move fastest: a median of two months.

This is the gap between two reviews, not between two appointments, and people often write a review well after a visit.

How far they go

They change dentist, not neighbourhood

The median switch is 5.1 km, and about half of unhappy switchers stay within 5 km.

These moves are usually local: 49.6% end up less than 5 km from the clinic they left. Disabled or vulnerable patients stay closest to home, with a median hop of 3.4 km.

What happens next

Whether the switch works, who keeps switching, and whether any of this is changing.

Does switching work

Seven in ten rate the next clinic 4–5 stars. One in four gives it 1 star.

Most rate the next clinic highly, but more than one in four has another bad experience.

70.6% of unhappy switchers rate the next clinic 4 or 5 stars. At the other end, 2,872 of 10,345 — 27.8% — leave another 1 or 2-star review. The switch usually ends with a much better rating, but not reliably for everyone.

Most reviewers only ever write about one clinic: 92 in 100.

22,716 Canadians have reviewed three or more dental clinics, and 429 have reviewed six or more. Some never settle; others simply review everything. Read it as a curiosity, not a finding.

The trend

Switching is not rising. Reviewing is.

The rate has sat between 3 and 5 unhappy switches per 1,000 reviews for a decade.

The raw count of unhappy switches rose from 89 in 2016 to 2,250 so far in 2026, but reviewing grew dramatically over the same period. Once the count is measured against reviews written, the unhappy-switch rate stays between 3 and 5 per 1,000 across the decade.

The dental care plan

The Canadian Dental Care Plan began rolling out in May 2024. Cost’s share of named reasons has moved between about 17% and 23% since 2019 with no clear break after the rollout, and the earlier years rest on far fewer moves. This dataset does not show the plan changing why Canadians leave.

Province and city

Quebec has Canada’s highest unhappy-switch rate

Quebec records 5.45 unhappy switches per 1,000 reviews. Nova Scotia switchers are least likely to rate the next clinic 4 or 5 stars.

Quebec has the highest provincial unhappy-switch rate in the dataset at 5.45 per 1,000 reviews. Alberta is lower at 3.75, and 75.6% of its switchers rate the next clinic 4 or 5 stars. The lowest next-clinic 4–5-star share is Nova Scotia at 58.7% of 126 moves, followed by Quebec at 65.5%.

Who loses patients

Clinics that never reply have twice the unhappy-switch rate

Review rating and reply behaviour track switching most clearly. Ownership and online booking show little difference.

Clinics that reply to most Google reviews record 3.36 unhappy switches per 1,000 reviews; clinics that never reply record 6.92. That is an association, not proof that replying prevents a patient from leaving: the clinics also differ in size and rating.

Low-rated clinics lose patients about ten times as often as top-rated ones, which is partly circular: those unhappy reviews are part of what makes the rating low. We hold the same figures for named dental groups but do not publish them, because group membership is read from clinic websites and is incomplete. Ask us if you need that cut.

What changes at the next clinic

When cost drives the switch, most still land where prices aren’t published

Seven in ten people who left over money and were glad they moved chose a clinic that does not publish its prices.

Among 1,085 people whose review complained about cost or a bill and who then rated the next clinic 4 or 5 stars, the share of clinics that publish prices rises from 26.0% to 30.0%, and direct billing from 40.5% to 43.5%. The clearer shift is reputation: the average Google rating rises from 4.62 to 4.80.

Their review complained about work that failed or had to be redone

1,157 people who complained about this and then rated the next clinic 4 or 5 stars. “Front desk praised” and the rest are mentions per 1,000 reviews at that clinic.

Clinic details are read from clinic websites as they stood on 12 September 2026. Praise counts are mentions per 1,000 reviews at that clinic. Only glad switches are counted, so each comparison is between a clinic that failed someone and one that satisfied them.

French and English

French-language switchers show half the median wait

The median gap is 2 months for French-language reviews and 4 months for English or other reviews.

Both groups have the same 5.1 km median hop. Language is detected with a simple word check on the review, so this split is indicative rather than a precise language classification.

About this study How it was built, and what it cannot show

We collect every Google review of every dental clinic in Canada. Google shows who wrote each review, so when the same person reviews two different clinics we can see the move. We never publish anything about an individual, and no clinic is named anywhere in this report.

The words we use

Move — one person reviewed clinic A, then a different clinic B within 24 months. 126,226 in total.
Local — the two clinics are at most 40 km apart. Longer hops are treated as moving house: 19,617 of them are left out.
Unhappy — the review at the clinic they left was 1 or 2 stars.
The study group — unhappy and local: 10,345 moves. Every figure on this page uses this one definition.
Glad they moved — unhappy, local, and they rated the new clinic 4 or 5 stars: 7,301.
Per 1,000 reviews — moves divided by all reviews written in that place or year, so busy cities and busy years compare fairly.

What it cannot show

It only covers people who write Google reviews, and unhappy people review more often than happy ones.
A move is worked out from two reviews. Nobody confirmed they changed dentist.
Moves over 40 km are treated as house moves, which removes real switches in rural Canada.
Timings are gaps between reviews, not between appointments.
Clinic details come from clinic websites and are current to 12 September 2026.
Everything here is a link between things. Nothing on this page shows that a clinic caused someone to leave.

What is still being validated

Done 23 September 2026: a blind check of 420 reviews showed the keyword rules could not sort reasons reliably, so all 8,654 reviews were then read whole by an AI reader against a fixed list of 13 reasons. 438 were read twice (94% agreement on the main reason) and a random sample was checked again.
Done 23 September 2026: the 12 quotes on this page were screened for names (no clinic names, no “Dr …”, no staff names from clinic websites), then each was read against the original review for identifying detail, whether it fits the reason it illustrates and whether it is fair to quote. They are the reviewers’ own words; cuts are marked “…”.
Figures for named dental groups stay unpublished while group membership is incomplete.
Re-check 2026 at year end: it is the highest rate in the series on an unfinished year.

Reporting this? Ask for the numbers behind any chart.

Every figure carries its sample size. We can share the underlying cuts for reporting or research, including by reason and province, by dental group, or for cities below our publication threshold. Journalists, researchers and dental organisations are welcome; we ask for a link back.
