We rendered 20 randomly drawn Canadian dental websites in a real browser and counted the fields a patient must fill in to request an appointment. The median is 5 or 6, the lightest ask for 4, and only four of the eighteen with a form ask for 8 or more. Form length is not this market’s conversion problem, and we will not sell it as one. What we did find: 6 of 20 clinics put no form on the homepage at all, and 2 have no native form anywhere — you have to find the page before you can start.
Why we measured this
Our earlier study of how 195 Canadian dental sites capture an inquiry found that 65.6% have a contact form and 94.4% have a click-to-call link. It could not tell us anything about what those forms actually ask for, and “your form is too long” is one of the most common things an agency will say in a free audit. We wanted to know whether it is true here before we ever said it to anyone.
So we drew 20 clinics at random from the 127 our crawler had flagged as having a form, opened each one, and counted.
How many fields does a dental appointment form ask for?
Five or six, typically. Across the 18 clinics in the sample with a form of their own, the median is 5.5 fields and the mean 6.9. Five of the eighteen ask for four or fewer. Nine sit in the five-to-seven band. Four ask for eight or more.
The usual shape is name, email, phone, preferred time and a message box. That is a reasonable thing to ask of somebody who wants an appointment, and it is close to the minimum that still lets a front desk call them back with something useful to say.
The long tail is where it gets uncomfortable: one clinic asks for 16 fields and another for 17 before you can request a first visit. Those are outliers, not the norm, and they are the only two in the sample where we would open a conversation by talking about the form.
The harder problem is finding the form at all
Only 12 of the 20 clinics have an appointment form on the homepage. Six require you to navigate to a contact or new-patient page first. Two have no native form anywhere we looked — both hand off to a third-party booking widget loaded in an iframe, which works if the widget loads and leaves no fallback if it does not.
A patient who has just decided to act is at their most willing in that moment. Asking them to find the right page first spends some of that willingness on navigation. Trimming a form from six fields to four moves far less than putting the six-field form where the decision happens.
- A short form on the homepage, not only a button that scrolls somewhere.
- The same form on the treatment pages that bring people in, not only on contact.
- A phone number next to it, because most dental inquiries are still calls.
- A visible fallback when the booking widget is a third-party embed.
Our first measurement was wrong, and the way it was wrong is instructive
We started by parsing the HTML of all 213 sites, which is fast, free and what most automated audit tools do. It returned a median of 8 fields, a mean of 10.4, and two clinics apparently asking for 97 and 185 fields.
Those two numbers were the tell. We opened both sites. One shows a four-field form — name, phone, email, message. The other shows eleven. The parser was counting inputs that exist in the page source but never render: page builders leave template copies and unused multi-step variants in the DOM, and no amount of parsing the markup can tell you which ones a patient actually sees.
Deduplicating by field name narrowed it — 185 became 93, 97 became 78 — and was still wrong by an order of magnitude. Only rendering the page fixed it. The rendered median came out at 5.5 against the static 8, so the fast method did not just produce two bad outliers; it inflated the whole distribution by roughly two fields.
If an audit tells you your dental booking form has eleven fields and you can see six on your own screen, this is probably why. It is also why our sample is 20 clinics rather than 213: we would rather report a small number we have looked at than a large one we have not.
What we are not going to tell you
That shortening your form will increase bookings. In this market the forms are mostly already short, and we have no measurement connecting field count to booked appointments at these clinics — only to what they ask. Anyone quoting you a percentage lift from removing two fields is quoting a study from a different industry.
We also are not going to tell you a form is where dental inquiries are won. 94.4% of these sites have click-to-call and the phone remains the dominant path, which is why we spend more time on what happens after the call connects than on what happens before the form is submitted.
Limits
Twenty clinics is a small sample and the median would move with a different draw. We report it because we verified every one by eye rather than trusting a parser, which we think is the better trade at this size.
The sample is also conditioned: we drew from clinics our crawler had already flagged as having a form, so it cannot tell you how many Canadian clinics have one. That number comes from the full crawl of 193 reachable sites, where 65.8% do — within rounding of the 65.6% we measured in a separate crawl earlier this month.
We counted what the form asks for, not whether it works. We did not submit anything. A form that asks for four fields and silently fails to deliver the message is worse than a long one that arrives, and that is not visible from the outside at all.

FAQ
Four to six covers it: name, phone, email, and enough context for the front desk to call back usefully. That is already what most Canadian clinics do — the median in our rendered sample was 5.5 fields. If your form is in that range, shortening it further is not the highest-value thing you could change.
Probably not, unless yours is unusual. Only 4 of the 18 clinics we measured ask for 8 or more fields and just 2 go past 15. If an audit flags your form length as a major problem, check the count on your own screen first — the automated methods overstate it.
Because they read the HTML rather than the rendered page. Page builders leave template copies and unused multi-step variants in the source, and a parser counts them all. We measured one clinic at 185 fields that way; the page shows 11. Deduplicating by field name still left it at 93. Only rendering the page gave the right answer.
On the homepage and on the treatment pages that bring patients in, not only on a contact page. In our sample 6 of 20 clinics require a patient to navigate to a second page before they can start, and 2 have no native form at all. That is a bigger friction than two extra fields.
It is fine as an addition and risky as the only path. Two clinics in our sample had no form of their own, relying entirely on an embedded widget. If it fails to load, is blocked, or is slow on a phone, there is nothing behind it. Keep a simple form and a phone number as the fallback.
We cannot tell you that from this data and we will not pretend otherwise. We measured what forms ask for, not what they produce. Published conversion figures for form length come from other industries, and dental inquiries skew heavily to the phone — 94.4% of the Canadian dental sites we audited carry a click-to-call link.
