The problem: did-not-attends drain a dental practice
Missed appointments are one of the most expensive problems in dentistry. Industry figures put dental no-show rates somewhere between 10% and 30% depending on the practice and its patient base. Every missed slot is lost income, wasted clinical time, and a patient whose treatment is delayed. Traditional reminders, a letter or a phone call the patient never picks up, are easy to miss.
The fix is not working the front desk harder. It is reaching the patient on the device they always have with them, with a reminder they will actually read in time to act on it.
The evidence: SMS reminders cut failed dental attendance
This is not a marketing assertion. A study at an NHS Dental Access Centre in Scotland measured failed attendance before and after introducing SMS text reminders. The result was a statistically significant fall in missed appointments.

Why SMS works when letters and email do not
The reason SMS moves the needle on attendance is simple: it gets read, and it gets read quickly. The channel data is stark next to email.
Widely reported industry averages for opt-in business messaging, not one practice's results. SMS open rates are typically cited around 98% against roughly 20% for email. Open rate reflects visibility rather than deep engagement.
Most texts are read within minutes, so a reminder sent a day or two before the appointment reaches the patient while there is still time to confirm, cancel, or rebook, which is what turns a would-be no-show into a filled slot.
How dental practices use Smart Follow Ups SMS
The same Smart Follow Ups number that answers your practice's calls sends the reminders that keep the diary full. Each message is short, factual, and private.
Booking confirmation
When an appointment is booked, an SMS confirms the date and time so it is captured straight away.
Pre-appointment reminder
A reminder one to two days before gives the patient time to confirm or rearrange rather than simply not turn up.
Easy cancel and rebook
Patients can reply to cancel, freeing the slot early so it can be offered to someone on a waiting list.
Recall prompts
With the right consent, gentle check-up recall texts bring patients back on schedule.
The reminder timeline
Illustrative flow. Timing is configurable. A cancelled slot spotted early can be offered to another patient instead of lost.
What a good dental reminder looks like
Keep it short, clear and private, no clinical detail, just what the patient needs to act:
Riverside Dental: reminder of your appointment on Tue 12 May at 3pm. Reply Y to confirm, or call 0113 000 0000 to rearrange.
It names the practice, gives the date and time, and offers a one-tap confirm and an easy way to rebook. That keeps it firmly a service reminder rather than marketing.
Kept compliant by design
Reminders about an appointment a patient has already booked are transactional service messages, not marketing, so they sit outside most PECR marketing-consent rules. You still need a lawful basis under GDPR to hold the number, and messages should identify the practice and avoid clinical detail for privacy. Recall marketing and offers are different and need the appropriate consent. For the full detail, see the PECR and GDPR SMS compliance guide.
Set this up for your practice
Any dental practice on Smart Follow Ups can send these reminders. The same number that answers patient calls sends the texts, so patients get one consistent, professional line of communication.
