How to send post-treatment care instructions automatically via WhatsApp

After a tooth extraction, a composite filling, or a periodontal treatment, patients leave the practice with a printed aftercare sheet — and most of them forget where they put it within 24 hours. When they do have questions, they call the practice. When the practice is closed, they call NHS 111 or search online and find alarming advice. Automating post-treatment care instructions via WhatsApp eliminates all three problems: patients have aftercare guidance on their phone, it arrives at the right time, and it invites them to reply with questions.

TL;DR

• Sending post-treatment care instructions via WhatsApp puts aftercare on patients' phones — where they'll actually look for it.
• Automated follow-up messages at 4 hours and 24 hours post-treatment catch problems early and reduce unnecessary calls.
• Treatment-specific templates ensure every patient gets the right instructions for their procedure.

Why printed aftercare sheets aren't enough

The printed aftercare sheet is a physical object that competes with car keys, appointment cards, and everything else in a patient's pocket. Studies of patient recall show that most people retain less than 50% of verbal medical instructions given immediately after a procedure, and that percentage drops further when the patient is still numb, anxious, or in discomfort.

WhatsApp delivers the same information to a device patients check dozens of times per day, at a moment when they are at home and able to read it properly. It also allows two-way communication: a patient who is worried about swelling at 8pm can message the practice and receive an automated response that either reassures them or advises them to seek urgent care.

Setting up treatment-specific aftercare templates

Effective WhatsApp aftercare requires templates matched to treatment type. A patient who has had a scale and polish needs different instructions from a patient who has had a lower third molar extraction. Sending generic aftercare to everyone is better than nothing, but it misses the opportunity to be clinically precise.

Common treatment categories that benefit from dedicated templates include:

Extraction (simple and surgical): Post-operative bleeding management, what to do if the socket re-bleeds, when to eat and what to avoid, signs of dry socket, pain management guidance, and when to contact the practice.

Composite and amalgam fillings: Bite sensitivity explanation, how long to wait before eating on the treated side, what to do if the bite feels high after numbness wears off.

Periodontal treatment (scaling and root planing): Post-treatment sensitivity, recommended interdental cleaning routine, when to expect improvement, follow-up appointment timing.

Whitening (in-chair and take-home): Food and drink to avoid during the treatment window, sensitivity management, how to use take-home trays correctly.

Crown and bridge: Temporary crown care, signs that the temporary has come loose, what to avoid eating.

Orthodontic adjustments: Wire comfort, wax application for rubbing, what to do if a bracket comes off.

Each template is created once in CodeWords and triggered automatically based on the treatment type recorded in the appointment in your practice management system.

The automated aftercare sequence

A post-treatment WhatsApp sequence typically runs over 24–48 hours:

Message 1 — sent 1–2 hours after appointment ends This is the core aftercare message. It contains the treatment-specific instructions in plain language, broken into short paragraphs or a numbered list that is easy to read on a phone screen. It ends with: "If you have any questions, reply here and we'll get back to you."

Message 2 — sent 24 hours after appointment A brief check-in: "How are you feeling after your [treatment] yesterday? If you have any concerns, we're here." This message is short — its purpose is to invite a response from patients who are experiencing problems but haven't reached out.

Message 3 — sent if the patient replies with a concern This is handled by Cody, CodeWords' AI automation assistant, which can recognise common post-treatment concerns (soreness, sensitivity, swelling, bleeding) and respond with appropriate guidance. Anything flagged as potentially urgent is routed immediately to a clinician or the on-call team.

Reducing out-of-hours calls

Out-of-hours patient calls are a significant burden for dental practices, particularly for practices that operate an emergency line or that are part of an NHS out-of-hours rota. A large proportion of out-of-hours contacts are from patients who had treatment earlier in the day and are worried about something that is entirely expected — soreness after an extraction, sensitivity after a filling, numbness that hasn't fully resolved.

A 24-hour WhatsApp aftercare sequence addresses many of these contacts before they happen. When a patient already has a message on their phone explaining that some soreness is normal for the first 24 hours and that they should contact the practice if they experience X, Y, or Z, they are more likely to self-triage correctly and less likely to call at 11pm worried about something that will resolve overnight.

Practices using automated post-treatment WhatsApp follow-up report a 20–35% reduction in out-of-hours contacts related to routine post-operative concerns.

Building patient confidence and reviews

Post-treatment follow-up has a secondary benefit that many practices overlook: it generates goodwill. A patient who receives a check-in message 24 hours after a painful extraction and has a positive reply experience is more likely to leave a Google review, recommend the practice to a friend, and attend their next appointment reliably.

Automated follow-up demonstrates that the practice is attentive beyond the appointment itself. At 24 hours post-treatment, if the patient's response indicates they're happy, CodeWords can include a soft prompt: "Glad to hear it — if you have a moment, we'd love to hear your feedback: [review link]." This places the review request at the optimal moment — when the patient is relieved the treatment went well and positively disposed toward the practice.

Integration with your PMS

For treatment-specific templates to trigger correctly, CodeWords reads the appointment type from your PMS after the appointment is marked as complete. Integration is available for Dentally, Practice Web, and Carestream.

The workflow is: appointment marked as completed in PMS → CodeWords identifies treatment type → appropriate template is queued → first message sends 1–2 hours later. No manual intervention is required.

Getting clinical sign-off on templates

Before going live, have the aftercare templates reviewed by your clinical lead or principal dentist. Templates that will go out automatically under the practice's name should reflect the practice's clinical standards and be consistent with advice from the British Dental Association and NICE guidelines where applicable.

Once templates are approved, they can be locked so that they are not edited without clinical review. This is particularly important for clinical claims — for example, what constitutes "normal" post-extraction bleeding versus a reason to seek urgent care.

Try it with one treatment type first

The easiest starting point is extraction aftercare, which is typically the treatment type that generates the most out-of-hours patient concern. Set up a single template, have it reviewed by your principal, and run it for 30 days. Track out-of-hours contacts related to extractions before and after, and measure any change in review volume.
