The short answer
Yes. Publish a price per visit type, and the price of any plan or package, editable by you without ringing a developer.
A hygiene visit is not an implant case. It is a known quantity with a known duration, and the price is the first thing a patient wants to know. A site that will not say it is a site that sends the patient back to the search results.
The objection, and why it does not hold here
The usual argument against published prices in dentistry is that treatment varies by patient, and a number on a page will be wrong for half of them. For complex restorative work that is a fair point.
Hygiene is different. You know how long a new patient visit takes, you know how long a returning visit takes, and you charge accordingly. The variation is a longer appointment or an added extra, both of which can be stated as a line on the same page.
The second objection is competitors. They can already find your prices by ringing your reception and pretending to be a patient, which takes about ninety seconds. Withholding the number costs you patients and costs a competitor nothing.
What actually stops bookings is ambiguity
Patients are not put off by a number. They are put off by not knowing whether the number they saw is the number they will pay.
So publish three things, not one:
The price. Per visit type, with the duration beside it.
Whether it is fixed or a from price. If more time or heavier work costs more, say so on the line, not at the chair.
What changes it on the day. One sentence, in your words, about what happens if the appointment needs longer than booked. That sentence prevents nearly every awkward conversation at the desk.
Where it goes
A price list page of its own, because that is what people search for and link to. A short version on the home page, so somebody who never leaves the first screen still sees a number. And a line on the what-happens page, near the booking button.
Every price line gets its own Book button, deep linked to that appointment type. The price list is where the decision gets made, so it is the worst possible place to make somebody navigate.
Keep it in step with the booking tool
Set your prices in Dentally, Software of Excellence, Cliniko, Jane, Acuity or Square Appointments first, then write the website from what the tool holds. A confirmation email that quotes a different number to the page the patient read costs more goodwill than any missing feature.
When fees rise, change three places on the same day: the booking tool, the website records and any printed sheet at reception. Put all three in the one calendar reminder.
Build it so you can edit it
The reason so many dental sites carry two-year-old prices is that the price list was built as a picture or a PDF, and changing it meant ringing whoever built the site. Build it as records with fields instead, so a fee change is a two-minute edit by you.
Editable also means honest. A price list that is easy to change stays correct, and a price list that is hard to change quietly becomes a lie.
Plans belong on the same page
If you run a membership or a hygiene plan, show the monthly price next to the pay-as-you-go price so the reader does not have to do the arithmetic. Two visits a year and a discount on extras is a common shape, and it only converts if the saving is visible.
The regulatory note
Advertising and fee transparency rules for dental professionals differ by country, and in some places there are specific requirements about how fees and any regulated scheme are displayed. Check what applies to you with your own regulator, because a website should never be the reason a clinic falls short of its advertising rules. This is orientation, not legal advice.
Where this sits
A visible, editable price list is one of the six things every hygiene clinic website we build carries, alongside direct-access messaging and booking with recalls, and the same pricing pattern runs through our dental practice websites. Our own packages are on pricing, for the same reason. Say the number, say what changes it, and let the patient book.
