The short answer
For most practices it is not either-or. Facebook and Instagram ads come from the same Meta Ads Manager and follow the same rules, so one campaign can run on both. The real difference is reach by age: in Pew Research Center's 2026 survey, Facebook is used by 70 percent of U.S. adults and Instagram by 51 percent, and the gap is widest for people over 50. Run both placements, break the results down by platform, and move budget toward the one that books more appointments for your practice.
One ad system, two apps
Meta owns both apps, and ads for both are created, paid for and reported in the same Ads Manager account. A single campaign can appear in the Facebook feed, the Instagram feed, Stories and Reels on either app. Meta's reporting can then split the results by platform and by position, so you do not have to guess which app did the work.
That changes the question. Instead of picking a platform up front, decide who you want to reach, set up one campaign, and let the platform breakdown show where your bookings come from.
Who uses each platform
Pew Research Center surveyed 5,511 U.S. adults between January and June 2026. These are the shares who say they ever use each app:
| Group | ||
|---|---|---|
| All adults | 70% | 51% |
| Ages 18 to 29 | 69% | 79% |
| Ages 30 to 49 | 78% | 64% |
| Ages 50 to 64 | 71% | 41% |
| Ages 65 and older | 59% | 21% |
| Women | 77% | 56% |
| Men | 63% | 45% |
| Rural residents | 76% | 40% |

Two things stand out for practices. Facebook reaches most adults in every age group, while Instagram drops off sharply after 50. And Instagram only leads among adults under 30. Usage is not the same as response to ads, so treat these numbers as a starting point for your test, not a verdict.
Matching the platform to the service
Think about who usually books each service at your office, then read the table again:
- •Implants, dentures and other services for older adults. Facebook does most of the work. Among adults 65 and older, Facebook use is nearly three times Instagram use.
- •Family and children's dentistry. Parents are often in the 30 to 49 group, where both apps reach most adults. Run both.
- •Whitening, aligners and other cosmetic services for younger adults. Instagram is worth a real share of the test here, alongside Facebook.
- •Rural and small-town practices. Facebook reaches far more rural adults than Instagram, so start there.
Rules that apply on both
Meta's Advertising Standards cover Facebook and Instagram alike. Three points come up most for practices:
- •No personal attributes. Ads may not assert or imply something about the viewer's health. "Missing a tooth?" implies a condition; "Implant consultations in Sacramento" does not.
- •Cosmetic procedures are 18 and older. Meta's Health and Wellness standard requires cosmetic procedure ads to target adults and bans statements that attack someone's appearance. The age rule does not cover dental products such as whitening products, but it does cover cosmetic treatments.
- •Neutral conversion names. Since September 2, 2025, Meta flags custom conversions that suggest a specific health condition and blocks them from new campaigns. Name events after the action, such as "Appointment request", not the treatment or condition.

Creative for each placement
The message can stay the same everywhere. The shape and pacing should not:
- •Feeds. A clear photo of your office or team, one sentence about the service, and a direct button such as Book Now or Call.
- •Stories and Reels. These fill the phone screen, so make a vertical version. Put the main point at the start, keep text away from the edges, and add captions so the ad still works with the sound off.
- •Real photos. Use your own team and office rather than stock images, so patients recognize the place when they arrive. Before you use any patient result, follow our before and after photos guide.
- •One landing page. Send both platforms to the same service page so differences in results come from the platform, not the page. Our landing page guide covers what that page needs.
How to test and split the budget
- Set up tracking for calls and appointment requests first, with neutral event names. Our conversion tracking guide explains the setup.
- Create one campaign for one service, targeted by location around your office and by age where the service calls for it.
- Leave both Facebook and Instagram placements on, with the same ad in feed and vertical sizes.
- After a few weeks, break the results down by platform in Ads Manager and match them with the bookings your front desk logged.
- Shift budget toward the platform with the lower cost per booked appointment, then test a new ad on the other one before you switch it off.
There is no fixed split that suits every practice. A rural implant office may end up almost entirely on Facebook, while a cosmetic practice near a university may see a strong Instagram share. If you also run Google Ads, compare all channels on the same measure, cost per booked patient. Our paid advertising team can set up the tracking and tests for you.

Frequently Asked Questions
Should a dental practice advertise on Facebook or Instagram?
Usually both, from one campaign. Facebook and Instagram ads are built in the same Meta Ads Manager and follow the same Advertising Standards, so you can show one campaign on both and let your own results decide where the budget goes. Facebook reaches more adults overall in Pew Research Center's 2026 survey (70 percent against 51 percent), while Instagram reaches slightly more adults under 30.
Which platform reaches older patients for implants or dentures?
Facebook. In Pew's 2026 survey, 71 percent of U.S. adults aged 50 to 64 and 59 percent of those 65 and older use Facebook, compared with 41 percent and 21 percent for Instagram. If most of your implant or denture patients are over 50, Facebook placements will reach far more of them.
Is Instagram better for cosmetic dentistry ads?
It can be, for younger adults. Instagram use is highest among 18 to 29 year olds (79 percent in Pew's 2026 survey). Keep in mind that Meta requires ads for cosmetic procedures to target people 18 or older and does not allow ads that put down someone's appearance, on either platform.
Do I need different ads for Facebook and Instagram?
You need different sizes more than different messages. Feeds, Stories and Reels show ads in different shapes, so make a vertical version for full-screen placements and check that text is readable on a phone. Keep the offer, wording and landing page the same so you can compare results fairly.
How do I know which platform brings more patients?
Break down your campaign results by platform in Ads Manager, then compare the booked appointments your front desk records for each, not likes or clicks. Give the test enough time to collect a meaningful number of bookings before you move budget.
Can I target my existing patients or people with a dental problem?
Be careful. Meta's Advertising Standards do not allow ads that assert or imply a viewer's health condition, and since September 2025 Meta flags custom conversions that suggest a health condition so they cannot be used in new campaigns. Target by location and broad age instead, name your conversion events neutrally (for example, Appointment request), and ask your own advisor before uploading any patient list.
