Open Dental vs Curve Dental: Which Is Right for Your Practice?

Feature comparison

The real pricing picture

On paper, Open Dental looks dramatically cheaper. At $149/month after the first year with no per-provider upcharge, it's the lowest sticker price in the market. Curve starts at roughly $299/month. But sticker price isn't the full story — and for most practices, it isn't even close.

With Open Dental: You need a server, either local hardware ($2,000–$5,000 upfront) or a cloud hosting service like Open Dental Cloud ($159/month per provider). You'll need IT support for updates, backups, and troubleshooting. Features that Curve includes — patient self-scheduling, digital forms, insurance verification, two-way messaging — each require a separate third-party subscription. Open Dental's eServices bundle runs $165/month for core digital tools. Weave, the most common add-on for phones and patient messaging, costs $279–$349/month with a $750 setup fee.

The math for a 2-provider practice: Open Dental base ($199/mo, year 1) + eServices bundle ($165/mo) + cloud hosting (~$125/mo) = roughly $489/month — before patient communication. Add Weave at ~$300/month and you're at ~$789/month. Curve at $299–$500/month all-inclusive suddenly looks comparable, or better. The gap that appeared to be $170/month on sticker price can flip to $289–$489/month in Curve's favor at this practice size. Open Dental offers volume pricing for larger groups — $169/month per location for 4 to 9 offices. For a 6-office group, that's $1,014/month in base fees alone, before add-ons or per-location hosting. Whether that beats Curve at that scale depends on how many per-user licenses each office needs — run both scenarios with each rep before committing.

With Curve: The monthly fee covers software, cloud hosting, automatic backups, updates, patient communication tools, insurance verification, and imaging storage. No server, no IT line items, no separate subscriptions. What you see is closer to what you pay — minus the annual commitment and renewal risk (more on that below).

The honest answer: for a solo practice with existing IT support and patient communication tools already in place, Open Dental is probably cheaper. For a practice assembling a stack from scratch, Curve often wins on total cost. Curve claims built-in insurance verification saves roughly 50 minutes per day in staff time — that's a vendor figure we couldn't independently verify, so treat it as a prompt for your own workflow analysis rather than a guaranteed return.

Curve's contract commitment

Curve requires a 12-month initial term that auto-renews annually at then-current fees. To cancel, you need to provide 90 days of written notice before the renewal date; cancel mid-term and you're on the hook for the remaining balance. For a practice that just escaped a 3-year Dentrix lock-in, this is a real improvement — but it's not month-to-month. Open Dental's initial 12-month contract drops to month-to-month after year one.

The auto-renewal clause also means your rate can increase at each annual renewal. Curve's contract renews at “then-current fees” with no published cap on increases. Startup pricing discounts, if offered, expire at renewal. Before signing, ask for a rate lock or a written cap on annual increases — see our Curve negotiation guide for specific asks to make before you sign, and our Open Dental negotiation guide for comparison.

Where Open Dental wins

• True data ownership. Open Dental is open source. Your data sits in a standard database format that you can export anytime, query directly, or hand to a developer. There's no proprietary lock-in, no extraction fees, and no vendor holding your data hostage. For practices that have been through a Dentrix data migration, this isn't abstract — it's the reason they switched.
• Customization depth. Because the source code is available, you can modify Open Dental to fit your workflow — build custom reports, create integrations via the open API, or hire a developer to add features specific to your practice. Curve gives you what it gives you. Open Dental gives you a platform to build on.
• Raw monthly cost. At $149/month after the first year with no per-provider scaling, Open Dental is unbeatable on sticker price — especially for multi-provider practices. A 10-provider practice pays the same base rate as a solo dentist, and volume pricing drops to $169/month per location for groups with 4 to 9 offices.
• Community advocacy. Across 175 practitioner reviews and forum threads, Open Dental gets the strongest organic recommendation of any PMS we reviewed. On Reddit's r/dentistry and DentalTown, practitioners describe switching as “the best thing I've done” — the kind of unsolicited endorsement that no vendor marketing budget replicates.

Where Curve Dental wins

• Zero IT burden. No servers to buy, maintain, or replace. No manual updates to install. No backup systems to manage. Curve handles all of it. For practices without dedicated IT staff — which is most practices — this removes an entire category of operational headaches.
• Built-in features that replace add-ons. Patient self-scheduling, digital forms, two-way messaging, and insurance verification are all included in the base subscription. With Open Dental, you'd assemble this stack yourself using Weave, RevenueWell, or similar tools — each with its own contract, login, and monthly invoice.
• Migration support. Curve's dedicated migration team has a structured onboarding process: an initial training session, six virtual follow-ups, and three months of proactive check-ins after go-live. With Open Dental, migration involves more coordination between your practice, the conversion service, and your IT setup.
• Ease of use and onboarding. Curve holds a 4.6/5 on G2 across 160 reviews, with ease of use as the most frequently cited positive. New front-desk staff can handle scheduling within hours rather than days, and the browser-based interface needs no local installation or configuration. Open Dental's interface is denser and more configurable — everything is accessible once your team knows where to look, but the learning curve for new hires is steeper, and that training time has a real cost.

Who should choose which

For a general dentistry practice doing bread-and-butter restorative work, both systems cover the clinical workflow. The deciding factor is whether your team has the appetite to manage infrastructure and assemble a software stack versus handing that responsibility to a vendor. Neither system includes a built-in orthodontic module, and each handles specialty billing differently — if either applies to your practice, verify compatibility before signing.

Open Dental fits tech-comfortable practices with existing IT support, multi-provider groups where per-provider pricing compounds fast, and any practice that wants to choose its own tools for communication, imaging, and analytics rather than accept whatever's bundled. The open-source model also suits practices that have been burned by proprietary data lock-in and want infrastructure they own outright.

If Open Dental is your match: request a demo, budget $2,000 for initial setup, and plan for a post-conversion setup appointment with a certified Open Dental trainer (approximately $50/hour for a 1-2 hour session, waived if completed within 30 days of conversion). For a broader look at value-focused options, see our best-value dental software rankings.

Curve is the better fit for practices that want to eliminate IT management entirely, teams that prioritize fast onboarding for new staff, and practices migrating off a legacy system that want the smoothest possible transition.

If Curve is your match: request a demo, ask for current pricing for your practice size in writing (Curve offers Starter, Standard, and Premium tiers), and get the contract terms — specifically the auto-renewal date and your cancellation deadline — before you commit. Our best software for small practices and best software for multi-location groups cover both in more depth.

Imaging compatibility

Imaging integration is the question the sales process rarely answers directly — and for a practice with DEXIS sensors, a CBCT unit, or Planmeca hardware, it can determine whether a switch is feasible at all. Neither vendor leads with this in their pitch.

Open Dental integrates with most DICOM-compatible imaging systems — DEXIS, Apteryx, Planmeca, and Sidexis — via bridge connections. Curve integrates with major imaging platforms but doesn't publish a compatibility list. Curve's browser-based architecture generally works with imaging software running locally, but the specific integration depends on your hardware model and the imaging software's own bridge support. Practices on DentalTown have noted confusion around Curve's imaging compatibility, particularly with hardware-connected sensors.

Before signing with either system: ask for written confirmation that your specific imaging hardware is supported. Get the answer from someone technical, not from sales. If the rep can't produce written compatibility confirmation, that's a reason to dig further before committing.

Billing and claims processing

Claims processing matters as much as charting, and this comparison rarely comes up in demos. Open Dental supports multiple clearinghouses — you choose your vendor and negotiate your own rates. ERA/EOB posting requires a third-party add-on, which means an additional contract, login, and integration to manage. Curve includes integrated billing, but confirm which clearinghouse they use, what the per-claim fees are, and whether you can switch clearinghouses if you're unhappy with claim turnaround times. A built-in billing workflow is convenient right up until you can't change it.

Migrating between the two

Moving to Curve from Open Dental: Curve's migration team handles the technical conversion. The actual go-live moment — when your team stops using Open Dental and starts in Curve — takes about 30 minutes when properly planned. The full process (data conversion, verification, training) takes 2-4 weeks from kickoff. Plan to run both systems in parallel for 24-48 hours after go-live, and schedule the cutover for a Monday morning. Insurance claims in progress often don't transfer cleanly and may need to be recreated. Curve states the final migration phase takes roughly 3 business days — that's their figure, and DentalTown reports suggest it can run longer when data cleanup is needed pre-migration. Ask your migration rep for a timeline in writing, not just a range from the sales deck. Post-migration support includes an initial training session, six virtual follow-ups, and three months of proactive check-ins. For more detail on what to prepare, see our guide to switching from Open Dental.

Moving to Open Dental from Curve: Curve's “Get My Data” feature exports your database in Excel-compatible format at any time — but images and documents require a separate support request, and Curve's data policy caps their max liability at three months of fees. Confirm your data export rights in writing before initiating any migration. Open Dental's conversion services cost $800–$1,400, and you'll need server infrastructure or cloud hosting in place before migration begins. Plan for a few days to one week to complete Open Dental setup and verification before going live.

One strategic note on vendor dependency: Curve was acquired by Constellation Software, a serial acquirer of vertical market software companies. Constellation's model is to hold products long-term and raise prices gradually — a different risk profile than a PE firm that flips in 3-5 years, but worth factoring into a multi-year infrastructure decision. Open Dental's open-source model is explicitly designed to prevent exactly this kind of vendor dependency. For more on the Curve direction, see our guide to switching from Curve Dental.

Also consider

If you're comparing these two, you're likely a practice looking for an alternative to the legacy incumbents. Dentrix vs Open Dental and Dentrix vs Curve Dental cover how each stacks up against the market leader. For multi-location groups or growing DSOs, Denticon (Planet DDS) is worth evaluating — it's designed specifically for multi-site operations in ways that neither Curve nor Open Dental prioritize out of the box. Our best software for multi-location practices covers it alongside both options here.
