What TCPA actually requires for dental SMS
TCPA distinguishes between marketing and non-marketing outbound contact. Marketing SMS — discount offers, new-patient promotions, anything pitching a service the patient did not ask for — requires prior express written consent. Non-marketing SMS, such as a recall reminder for an existing patient already in the schedule, requires prior express consent, which is a lower bar but still requires affirmative opt-in.
The dental wrinkle is that the line moves. A routine recall reminder is usually non-marketing. The moment that reminder adds a discount, a referral incentive, or a new-service mention, it pushes toward the marketing classification, and the consent standard tightens with it.
