For a typical 6-person dental office (dentist, two hygienists, an assistant and two at the front desk), Yodl is our first pick: $12 a month flat with a signed BAA on that plan. Microsoft Teams Essentials ($4 per user a month paid yearly, as of November 2026) is the pick if you already live in Microsoft 365, and Spruce Health is the pick if you also want patient texting from the practice number.
What a dental office actually sends all day
Dental chat is not small talk. It is the assistant telling the front desk that the crown for the 2 o'clock patient came back from the lab and needs a seat appointment. It is a hygienist out sick at 7 a.m. and six recall patients to move. It is the front desk asking the dentist to confirm phase two of a treatment plan before presenting the fee. It is a photo of tooth number 30 with the question 'watch or restore?'. Every one of those messages ties a name to care, which makes it protected health information (PHI).
That is why the app matters. A vendor that stores PHI for you is a business associate under HIPAA and must sign a Business Associate Agreement (BAA), the contract that binds it to protect that information, before the first message. Consumer apps do not sign one, so a WhatsApp group for the hygiene schedule is a problem even when nobody thinks of it as a medical record.
How we chose
- A BAA on the plan a 6-person office would buy, not an enterprise tier.
- Price for 5 people, then the real number for 6.
- Channels for front desk, hygiene and the doctor, plus photo and PDF sharing for lab slips and x-rays.
- Apps on staff phones and a desktop at the front desk.
- Audit and retention controls, and honesty about what the tool lacks.
All prices are as of November 2026, from each vendor's own site. They change, so verify before you buy.

The tools, one by one
Yodl
Yodl is first because a 6-person office pays $12 a month ($10 for the location with 5 users, plus $2 for the sixth) and the BAA is signed on that plan. Set up #front-desk, #hygiene, #lab-cases and a private #doctor channel, drop the lab slip PDF or the intraoral photo straight into the thread, and search 'crown' next week to find it. Roles let a part-time biller read #front-desk without posting, and the audit viewer with CSV export shows who saw what. It has no voice or video calls, no SSO yet, and the iPhone app is in beta.
Microsoft Teams Essentials
Teams Essentials is $4 per user a month paid yearly, so 6 people cost $24 a month on an auto-renewing annual subscription. Microsoft's HIPAA BAA applies by default through its Online Services Data Protection Addendum on commercial plans. If the office already runs Outlook and Excel through Microsoft 365, Teams is sitting there with the BAA included; the trade is a heavier app built around meetings.
Google Chat (Google Workspace)
Google Chat comes only with Workspace. Business Starter is $7 per user a month on an annual plan or $8.40 flexible, so 6 people cost $42 or $50.40. An admin accepts the BAA in the Admin console and Google lists Chat among the covered services.
Zenzap
Zenzap feels like WhatsApp with to-dos, checklists and AI agents, and it can migrate WhatsApp chats. Business+ is $50 total a month for up to 5 users with the annual toggle selected by default; a sixth user moves you into the 'Up to 20 users' tier, which shows 'Book a Demo' instead of a price. HIPAA compliance with a signed BAA is an add-on with no published price.
Spruce Health
Spruce is patient communication with team messaging included: a HIPAA phone line, two-way patient texting for confirmations and post-op check-ins, e-fax for referrals and video visits. Basic is $24 per user a month, taxes and fees extra, so 6 people cost $144, and the BAA applies to all trials and plans. All users must be on the same plan. It is the right buy when patient texting is the main goal.
Slack
Slack Pro is $8.75 per user a month on monthly billing, so 6 people cost $52.50, but Slack's HIPAA support is limited to Enterprise plans with an executed BAA and DLP monitoring. Using Pro means keeping patient information out of chat entirely, which in a dental office is close to impossible. See Yodl vs Slack.
Pumble
Pumble is free for unlimited users with 10 GB per workspace, and Pro is $2.49 per seat a month billed annually. Our research found no HIPAA or BAA statement on its pricing or security pages, so it belongs to the holiday-party channel, not the lab-case channel.
Which one for your office
- Single-location office of 4 to 10 people: Yodl, $10 plus $2 per person above 5.
- Already paying for Microsoft 365: Teams, with the BAA already in place.
- Email on Gmail and Drive: Google Chat on Workspace.
- Patient texting is the real goal: Spruce Health, and consider Yodl for staff who never text patients.
- Two or three offices under one owner: Yodl at $10 per location.
- Two or three people total: Chanty Business at $3 per user a month billed annually, with a BAA, costs less than $10.
Yodl is $10 a month for 5 people with a signed BAA, on the pricing page.
A dental office moves patient information all day, so the chat app must sign a BAA on the plan you buy. For 6 people, Yodl at $12 flat is the cheapest way there; Teams and Google Chat work if you already pay for the suite.
Frequently asked questions
Can hygienists and the front desk use WhatsApp for schedule changes?
Not for anything with a patient name in it. WhatsApp's terms say Meta is not a business associate, so there is no BAA, and a name next to an appointment time is PHI.
Can we discuss lab cases in chat?
Yes, inside a tool that has signed a BAA. Share the minimum necessary: the patient, the case, and what needs to happen, in a channel only the people involved can see.
What happens when a hygienist leaves?
Remove the user the same day. In an invite-only workspace with roles and an audit log, that ends their access and leaves a record; in a WhatsApp group, the chat history stays on their phone.
Is Pumble HIPAA compliant?
Our research found no HIPAA or BAA statement on Pumble's site. Treat it as a general chat tool and keep patient information out of it.
Does a dental office need end-to-end encryption?
No. HIPAA treats encryption as an addressable safeguard, and tools like Teams, Google Chat and Yodl encrypt in transit and at rest without end-to-end encryption so that audit and search work.
