Google Ads vs Facebook Ads for dentists: where the first full-arch dollar goes

Most practice owners asking this question have already decided to spend the money. What they are really asking is which platform is less likely to waste it.

The answer is less about the platforms than about which job you need done this quarter.

Search finds demand. It does not create it.

Google Ads reaches people who have already concluded something is wrong and gone looking for a fix. That is the most valuable audience in dentistry and also the smallest. Someone typing “all on 4 cost” has done the emotional work already. You are not persuading them that treatment exists. You are persuading them to have it with you.

The catch is volume. In most metros, the number of people searching full-arch terms in a given month is finite and modest, and you can reach the ceiling of it faster than you expect. A practice running search well will hit a point where more budget buys worse searches, not more cases. That moment is not a failure. It is the channel telling you it has given you what it has.

Start on Google anyway

For a practice putting its first real dollars into paid media, search is almost always the right opening, and the reason is diagnostic rather than strategic.

Search fails legibly. If the campaign does not produce, you can see exactly where it broke: the search terms report shows what you actually paid for, the landing page shows where people left, and your booking data shows whether the consults were real. You can launch it this week without a production shoot. And because intent is high, the gap between an ad click and a seated consult is short enough that you learn something inside a month.

That last part is what most owners are actually buying with a first campaign. Not cases. Information about their own funnel.

Run search for a quarter and you will know your cost per booked consult, your show rate, and whether your consult converts. Practices skip this and go straight to a big multi-channel launch, then spend six months unable to say which part is broken.

What Google will do to your budget if you let it

Left alone, Google will spend your money on “dentist”, “tooth pain” and “dentures near me”, and it will bill every one of those at implant prices.

This is the single most common leak we find in dental accounts, and it is not subtle. Broad match with no negative keyword discipline turns a full-arch campaign into a general dentistry campaign that happens to cost forty dollars a click. The fix is unglamorous: tight match types, a negative list that grows every week, and someone actually reading the search terms report rather than the dashboard summary.

The second leak is the destination. Expensive full-arch clicks sent to a practice homepage ask a frightened, expensive visitor to navigate. A homepage is a menu. What that click needs is one page that answers candidacy, gives a cost range, mentions financing and offers a single next step.

Meta’s job is different, and so is its scoreboard

Facebook and Instagram reach the much larger group of adults living with failing dentition who have not searched for anything. They know their teeth are a problem. They have not yet decided it is a solvable one, and many of them assume the answer is dentures.

That is real, addressable demand, and search will never touch it.

But it behaves differently. The person who sees your ad on a Tuesday evening is not in a decision moment. They are in a recognition moment. Weeks can pass between that and a booking, and the creative has to do work that a search ad never has to do. It has to make the procedure sound survivable, and it has to show a real outcome on a face that looks like theirs.

The mistake that kills most Meta budgets

A practice runs search at a certain cost per lead, launches Meta, sees a higher cost per lead in week three, and shuts it off.

We see this constantly, and it is the wrong comparison. Cost per lead on Meta is measured against a colder audience over a longer decision window. Held to a search benchmark inside thirty days, it will always look worse, right up until the month those people start booking and the practice attributes the lift to something else.

If you are going to run Meta, commit to judging it on booked and seated consults over a rolling window, and accept that some of those consults will not be traceable to a click. A patient who saw your ad in March and searched your practice name in May shows up in your analytics as organic. That is not a measurement failure to be solved with better software. It is what demand creation looks like.

The number that actually settles it

Neither channel wins on cost per click or cost per lead. Both of those can be improved by attracting worse people.

The comparison that matters is cost per booked, qualified consult, and then what those consults do once seated. Take a practice with a $30,000 average case, closing three in ten seated consults. Every seated consult is worth $9,000 in expected revenue before it happens. Against that, a channel producing consults at $600 apiece and a channel producing them at $1,100 are both profitable, and arguing about which is cheaper misses that the practice should probably be running both at capacity.

What would change the answer is a close rate of one in ten. Then no channel is cheap, and the money belongs in the consult room rather than the ad account.
