Quick answer: All-on-4 dental implants replace a full arch of teeth using just four implants that support a fixed, non-removable set of teeth. They suit people missing most or all of their teeth, or anyone tired of loose dentures. In Ontario, All-on-4 dental implants typically cost about $20,000 to $35,000 per arch.
If you are missing most or all of your teeth, you have probably come across All-on-4 dental implants as a way to get a complete, fixed smile. It sounds almost too good to be true: a whole arch of teeth on just four posts. This guide explains how it works, who it suits, the process, and the cost, so you know exactly what to expect.

What Are All-on-4 Dental Implants?
All-on-4 is a type of full mouth dental implants treatment that supports a complete set of fixed teeth on four implants per arch. Instead of placing a separate implant for every missing tooth, your dentist uses four well-positioned posts to anchor a full bridge. The result is a fixed, natural-looking smile that does not come out at night. A closely related option, All-on-X, uses the same idea with a different number of implants based on your needs.

| Type of teeth | Fixed, non-removable |
| Best for | Missing most or all teeth in an arch |
| Typical Ontario cost | About $20,000 to $35,000 per arch |
| Time to final teeth | Usually about 3 to 6 months of healing |
How Do All-on-4 Implants Work?
The clever part is the placement. Two implants are placed straight at the front of the jaw, and two are angled at the back. That angling makes the most of the available bone, often without the need for a graft, and gives the bridge strong support. Because only four implants are needed, many people can have a full All-on-4 arch placed in fewer appointments than a mouth full of separate implants. In many cases a temporary fixed set of teeth can be placed soon after surgery, with the final teeth fitted once healing is complete.
Who Is a Good Candidate?
All-on-4 is designed for people who are missing most or all of their teeth in an arch, or who are worn out by dentures that slip and shift. Because the angled implants make good use of existing bone, many people who were told they did not have enough bone for traditional implants are still candidates. You will need reasonably healthy gums and enough bone to support the four posts, which a 3D scan confirms. A consultation is the only way to know for sure.
Benefits of All-on-4
- A fixed, confident smile: Your teeth stay put when you laugh, eat, and talk. No adhesive, no nightly soaking.
- Eat what you love: A stable bite lets you enjoy a much wider range of foods than dentures allow.
- Protects the jawbone: Like all implants, the posts stimulate the bone and help prevent the shrinkage that follows tooth loss.
- Fewer implants, lower cost per tooth: Four implants supporting a full arch is more cost-effective than replacing every tooth on its own.
- A true permanent teeth replacement: With good care, All-on-4 offers a long-lasting, fixed solution rather than a removable appliance.
The All-on-4 Process
- Consultation and 3D scan. Your dentist checks your bone and gums and builds a treatment plan.
- Implant placement. The four implants are placed under local anesthesia, with sedation options if you feel anxious.
- Temporary teeth. In many cases a temporary fixed set is placed soon after, so you are not without teeth.
- Healing. Over a few months the implants fuse to the bone.
- Final teeth. Your custom, permanent bridge is fitted and your full mouth restoration is complete.
How Much Do All-on-4 Implants Cost?
In Ontario, All-on-4 commonly ranges from about $20,000 to $35,000 per arch. That is a real investment, but it replaces an entire set of teeth and tends to cost less than placing an individual implant for every tooth. The exact figure depends on your case, materials, and whether any prep is needed. For a fuller breakdown, see our guide to dental implant cost in Woodbridge.
