What happens to cloud dental software if my internet goes down?

With cloud-hosted software, an internet outage can stop the practice, because the database lives in the vendor data center. If you go cloud, treat a redundant or failover internet connection as essential rather than optional. On-premise software keeps working on your local network during an outage.

Does cloud software mean I no longer need IT support?

No - cloud relocates IT, it does not remove it. You still need a solid network, endpoint security, a business firewall, BAAs, and a tested path to recover your own data. A reliable internet connection and good local hardware become more important with cloud, not less.

Cloud vs on-premise dental practice-management software: pros and cons

Q: Is cloud or on-premise dental software better?

Neither universally. On-premise keeps your database on a local server, works through an internet outage, and gives full control, but you own the server and backups. Cloud reduces local hardware and shifts maintenance to the vendor, but makes your internet connection mission-critical. The right choice depends on your internet reliability and how much local IT you want to own.

Cloud vs on-premise dental practice-management software

On-premise software keeps your database on a server in your office; cloud (hosted) software keeps it in the vendor's data center and you reach it over the internet. On-premise gives you more control and works through an internet outage, but you own the server, the backups, and more local IT. Cloud reduces local hardware and shifts maintenance to the vendor, but makes your internet connection mission-critical. Neither is universally "better" - it depends on your practice.

On-premise: pros and cons

Pros:

Works even when the internet is down - the database is on your LAN.
Fast local performance for imaging and charting on a well-built network.
Full control over your data, configuration, and backups.

Cons:

You own the server, its lifecycle, and its replacement.
Backups, patching, and security are your responsibility (directly or via your IT provider).
More local hardware and more local IT to manage.

Cloud / hosted: pros and cons

Pros:

Little or no on-premise server to buy, maintain, or replace.
The vendor handles much of the patching, scaling, and infrastructure backup.
Access from multiple locations is often simpler.

Cons:

Your internet connection becomes mission-critical - an outage can stop the practice.
Ongoing subscription cost instead of a capital purchase.
You depend on the vendor's uptime, security, and data-export terms.

The questions that decide it

How reliable is internet in your area, and can you afford a failover connection? Cloud without redundant internet is a single point of failure.
How much local IT do you want to own? On-premise trades convenience for control.
Multi-location plans? Cloud can simplify multi-site access.
What does your chosen software actually support? Some systems are on-premise-first, some cloud-first, some both. (See Open Dental vs Dentrix vs Eaglesoft.)

Either way, the fundamentals do not change

Cloud does not eliminate IT - it relocates it. You still need a solid network, endpoint security, a business firewall, BAAs, and - even with a hosted database - a clear, tested path to get your own data back. "Tested restore" matters in both models. (See do my dental backups actually work? and what happens to your data when you switch.)
