Dentistry is advertised under rules the General Dental Council enforces directly. Its guidance on advertising requires that information about services is accurate and not misleading, that the GDC registration numbers of the registrants involved appear in practice literature and online, and that the site sets out the complaints procedure — including who a patient contacts if they are unhappy with the response, which is the relevant NHS body for NHS treatment and the Dental Complaints Service for private work. Titles are the trap most practices fall into. A dentist who is not on a GDC specialist list must not use titles that imply specialist status, so 'orthodontist', 'periodontist' and 'endodontist' are off the table unless the registration supports them, and there are no specialist lists at all for dental care professionals. Practices offering facial aesthetics inherit a second problem entirely: botulinum toxin is a prescription-only medicine and cannot be advertised to the public, so the treatment page many practices run is a compliance risk before anyone reads a word of it.
Underneath that sits a commercial split that most practice websites ignore. Routine demand is high volume, low value and immediate — somebody with toothache at seven in the morning, or a family that has just moved into the area, searching on a phone and phoning whoever answers. Cosmetic demand behaves like a considered purchase. Implants, full-arch work and clear aligners run into four figures and often five, the research phase stretches over weeks, and the same person will read cost pages, look at finance options, compare three practices and book a consultation before anyone touches their mouth. Clicks on implant and aligner terms are among the most expensive in UK local search because every practice within twenty miles wants them. Running both through one campaign means the cheap, high-volume routine clicks absorb the budget and the expensive cosmetic clicks are throttled, or the reverse — either way the account is optimising against itself.
Then there is NHS demand, which is the most misunderstood part of dental marketing. Searches for an NHS dentist taking on new patients carry enormous volume and almost no commercial value to a practice that is already at capacity on its UDA contract. Attracting them fills the phone lines, exhausts reception and produces nothing. The economics that do matter are unit economics over time: a registered patient returning for examinations and hygiene appointments for a decade is worth a great deal more than the first appointment suggests, which is why an acquisition cost that looks alarming per enquiry can be entirely sensible per patient. Practices that only track cost per form fill never see this, and cut the campaigns that are actually working.
