Calls a dental office in Riverside, CA has to catch
Dental appointments are booked, moved and confirmed by phone, and a new patient whose call goes unanswered can simply dial the next practice on the list. Front desks also juggle insurance questions and hygiene recalls while patients are standing at the counter. That holds for dental offices in Riverside, CA as much as anywhere.
A few of the calls that come in to dental offices in Riverside, CA:
- A specialist's office calls to coordinate a referral.
- The front desk calls a list of patients who are overdue for a cleaning.
- A patient with a cracked tooth calls first thing in the morning asking for a same-day visit.
Texting patients
Dental front desks text appointment confirmations, reschedule requests and simple directions to the office.
Team texting on Callata runs from your business number, so replies come from the practice or shop rather than someone's personal phone. It turns on after the one-time $49 carrier registration (10DLC) is approved.
