Google LSA and TikTok Are Stealing Your New Patients

Forty-six thousand eight hundred dollars. That's the annual cost of a $3,900-a-month Google Local Services Ads budget, and in a typical single-location general practice it buys somewhere around eleven genuinely new patients a month once you strip out the wrong-service calls, the no-shows, and the people who were searching your practice name anyway. LSA doesn't create demand. It stands at the door where demand already arrives and charges admission.

So here's the call you can argue with: a single-location practice spending more than $1,500 a month on LSA while posting nothing on TikTok has its budget pointed in the wrong direction. One of those channels is a toll booth on patients who already decided to find a dentist. The other is where the deciding happens. We'd move the money, and we'd do it this quarter.

55% of Your Town Already Decided Not to Come

The constraint on your schedule is almost never a shortage of mouths. In 2022, 45% of the U.S. population had a dental visit in the past 12 months, and only 40% of working-age adults 19 to 64 did, according to the ADA Health Policy Institute. Flip that: three out of five adults in your prime production age band did not sit in anyone's chair last year.

That's the whole strategic problem in one number. Those people are not comparing you to the practice across the plaza. They are not comparing at all. They have no active search, no insurance question, no pain yet. They will never type "dentist near me," which means they will never appear in your LSA dashboard, which means every dollar you put into LSA is a dollar fighting over the 40% who are already in motion.

Meanwhile the supply side keeps filling in. The Bureau of Labor Statistics puts the median annual wage for dentists at $176,110 in May 2025, with employment projected to grow 6% from 2025 to 2035 and about 4,800 openings per year. More chairs, more bidders, same 40% of adults raising their hand. That math only runs one direction: the price of intercepting an in-motion patient goes up every year, forever.

What Most Owners Get Wrong: They Grade LSA on Cost Per Lead

The specific mistake is treating cost per lead as the number that matters. The owners who make it are almost always the two-doctor practices where marketing lives with an office manager who has eleven other jobs, plus the solo owners who inherited a vendor from a study club and read the monthly PDF without ever listening to a call.

Here's why cost per lead lies. LSA charges you per lead, not per click, which sounds like it transfers risk to Google. It doesn't. A "lead" includes the patient calling to ask whether you take their plan, the patient who wanted an oral surgeon, the patient calling from four towns over, the existing patient who googled your name instead of scrolling their contacts, and the price shopper working through page one. Your dashboard scores all of those identically. Your bank account does not.

The second lie is attribution. A meaningful share of LSA charges come from branded or near-branded searches, people who already had your name from a neighbor, a hygienist, a school directory, or a sign. Google bills you to deliver a patient your existing reputation already closed. That's the actual theft in the title. You're not buying patients on LSA; you're paying rent on your own name.

The number that matters is cost per net-new patient who actually sat down and started treatment. Nobody's dashboard reports that, which is exactly why owners keep renewing budgets that don't clear their own hurdle.

Where $3,900 a Month in LSA Actually Lands

Run it with conservative, boring assumptions. These are modeled figures, not survey results, and the point is the shape of the funnel, not the decimals. Say you spend $3,900 a month at an average charged lead cost of $65. That's 60 leads.

Strip the unbookable traffic, the wrong-service calls, the out-of-area calls, the pure price shoppers, and the plan-verification calls that end in a no. Call that 30%, which is generous to the channel. You're left with 42 bookable conversations.

Your front desk books half of those, because LSA calls hit live during production hours and some go to voicemail. That's 21 appointments.

Paid-search new patients cancel and no-show at a higher rate than referrals, so take 20% off. You seat about 17.

Now the honest haircut. Assume 35% of those were branded or referral-driven searches you'd have captured without paying. Net-new is roughly 11 patients.

That puts your true cost per net-new seated patient at about $357, not the $65 on the invoice.

Now the return. If a first-visit new patient collects $700 in year one at a 60% contribution margin, each one throws off $420. Eleven of them produce about $4,586 in contribution against $3,900 in spend.

That's $686 a month of margin, or $8,232 a year, for the privilege of running a channel that requires review management, call monitoring, and someone's attention every week.

Our view: that's not a growth channel, that's a part-time job that pays $8,232 and goes to zero the moment a corporate group in your zip code decides to bid harder. And every assumption above was tilted in LSA's favor. Move the branded-search haircut to 50% and the whole thing goes underwater.

TikTok Stopped Being a Teen Problem Years Ago

The reflex objection is that TikTok brings kids who can't consent to treatment and won't pay. Check the audience. Pew Research Center reports that one-third of U.S. adults say they use TikTok. That's not a youth channel. That's a third of the adult population in your drive time, including the 19-to-64 cohort where only 40% had a visit last year.

And the teen numbers aren't a liability, they're the ortho pipeline. Pew's teen data shows about 60% of U.S. teens use TikTok, 61% visit it daily, and 21% say they use it almost constantly. If you sell clear aligners, whitening, bonding, or anything cosmetic, the single most daily-habituated audience for that work is on a platform most practices treat as a hobby.

The economics run the other way from LSA, too. Say you pay someone $1,200 a month to shoot and edit twelve posts, mostly on your own phone between patients. If that produces two aligner starts a quarter at a $4,200 fee and a 50% contribution margin, each start returns $2,100, so two returns $4,200 a quarter, or about $1,400 a month in contribution.

That clears the $1,200 cost on case acceptance alone, before you count a single hygiene patient, and it beats the LSA line by roughly $714 a month at the same effort level.

The structural difference matters more than the margin. Turn off LSA and the leads stop the same afternoon. Turn off TikTok and the library you built keeps getting served, keeps getting searched, and keeps answering the question a nervous 34-year-old has at 11 p.m. about whether a crown hurts. One is rent. The other is an asset on your balance sheet that nobody books as one.

The Testimonial Rule That Outlives Your Video

Here's where practices get themselves in trouble fast, and where the TikTok-is-free argument collapses. Patient-facing content is advertising, and your state board treats it that way. Ohio is a clean example: under Ohio Administrative Code Rule 4715-13-01, subsection (C) restricts that "testimonials or endorsements may be made only by patients of record," and advertising must be retained for two years and produced to the board within 24 hours of a request.

Read that twice if you run reels. The friendly influencer who never sat in your chair cannot endorse you. The staff member playing a happy patient is a problem. And a 24-hour production window means you need an archive, not a vibe: every posted video, every LSA ad variant, every caption, saved with its run dates, for two years. Most practices we see could not produce last March's deleted reel in 24 hours if the board asked, and "we took it down" is not a defense when the retention clock was already running.

Rules vary by state, so pull your own board's advertising language before your next shoot. The operational answer is the same everywhere: one shared drive folder, named by date, holding the raw file, the final cut, the caption, and a signed release from a patient of record. Ten minutes per post. Cheaper than one complaint.

What We'd Do With a $4,000 Marketing Budget

We wouldn't kill LSA outright. We'd cap it at $1,200 to $1,500 a month, enough to defend your name and catch genuine emergency search, and we'd stop pretending it's growth. We'd put $1,200 into consistent short-form video with a real archive and release process, and we'd spend the rest on the two things that actually convert the 60% who aren't looking: recall reactivation on your own dormant list, and same-day answer rates on the phone.

We wouldn't take the vendor deal that bundles LSA management into a 12-month contract with a percentage of spend. That pricing pays your agency more for a channel whose cost per net-new patient you can't verify. And we wouldn't let a single-location practice run both channels on autopilot while nobody listens to the calls. Pick the one you'll actually work.

Four Moves Before Friday

Pull 30 days of LSA call recordings and tag each one: bookable, wrong service, out of area, price shopper, existing patient. Divide your monthly spend by the patients who actually seated and started treatment, and compare that number to the $65 on your invoice. Set your LSA cap at a number you'd defend in writing, then build the content archive folder with dated subfolders and a patient-of-record release form before you shoot anything. Then schedule four 20-second videos answering the four questions your front desk hears most.

What we're tracking next: whether LSA booked-appointment rates hold as more corporate groups enter the auction, and whether TikTok's in-app search starts showing up as a named referral source on new-patient forms rather than hiding inside "found you online." What would change our mind is a practice producing clean call-level data where LSA clears $200 per net-new seated patient and holds there for two quarters. Show us that and we'll move the money back.

Before you renew any marketing contract, find out what your marketing line is really doing to your overhead. Our free overhead calculator breaks your spend down by category so you can see what percentage of collections is going to patient acquisition versus the rest of the practice, and whether that $46,800 LSA budget is buying growth or buying rent. It takes about four minutes with a P&L in front of you: run your own numbers.
