If you are exploring options to replace missing teeth, you have probably come across the term “permanent dentures.” The tricky part is that permanent dentures can mean several different things depending on who you ask. Some dentists use the term to describe high-quality removable dentures. Others use it to describe implant dentures. Many patients use it to refer to fixed full arch implants that never come out.
This guide explains what permanent dentures actually are, the differences between all the options, and how to decide which treatment may be right for you.
What Are Permanent Dentures?
Permanent dentures is a term for tooth replacement solutions designed to stay securely in your mouth for long periods of time, instead of regular dentures which are typically removed daily. However, the phrase “permanent dentures” can generally refer to three very different categories.
1. Final or premium removable dentures
Some practices call the final, custom-made denture the “permanent” denture. These are still removable, but they are designed to fit better and last longer than temporary healing dentures.
2. Implant dentures
Also called snap-in dentures, overdentures, or implant-supported dentures. Two or more implants are placed in the jaw and the denture snaps onto them. The implants stay in permanently, but the denture (the tooth portion) can be removed at home.
3. Fixed full arch implants
Also known as All-on-X or fixed implant bridges. These use four to six implants per arch and a permanent, non-removable full bridge that is screwed into the implants. Only your dentist can remove it.
Because the term “permanent dentures” is used inconsistently across the industry, patients are often unsure which solution they are reading about. Understanding these categories is the first step toward choosing the right option.
Types of Permanent Dentures Explained
Premium removable dentures
These are the most affordable option. Patients receive an initial healing denture after extractions and then a final custom denture once the gums have healed. They are still removable, but they fit much better than older styles. They do not stop bone loss in the jaw.
Implant dentures or snap-in dentures
These use two to four implants per arch. The denture snaps in and out. Benefits include more stability, less slipping, and better chewing ability than removable dentures. The denture must still come out for cleaning.
Fixed full arch implants
This is often what patients mean when they search for permanent dentures. These are non-removable and act like natural teeth. Fixed full arch implants stay in the mouth at all times, restore almost full chewing ability, and prevent bone loss in the jaw.
Benefits of Permanent Dentures
Although the benefits differ based on the type of solution, most permanent denture systems offer:
- Improved stability when eating
- Better speech
- Greater comfort compared to loose traditional dentures
- Better confidence when smiling and laughing
- Less or no need for denture adhesives
- A more natural look and feel
- The ability to prevent bone loss if implants are used
Fixed full arch implants provide the highest level of stability and function, but they also require the largest investment.
How Long Permanent Dentures Last
Durability depends on the type of permanent denture:
- Removable premium dentures often last about 5 to 7 years.
- Implant dentures can last many years, although the denture portion may eventually need to be replaced.
- Dental implants are designed to last a lifetime with proper care.
- Fixed implant bridges often last 10 to 20 years or longer, depending on material and care.
Patients often wonder whether the denture or the implant is the “permanent” part. In most cases, the implants are permanent, while the restoration sitting on top – the crown, or visible part – may eventually need replacing.
Are Permanent Dentures the Same as Dental Implants?
Not always. Dental implants are the titanium or zirconia posts placed in the jawbone. Permanent dentures refer to the denture or bridge that attaches to those implants. Implants can support a single crown, a bridge, a snap-in denture, or a fixed full arch restoration.
Patients sometimes confuse these terms, which is understandable, because much of the online information combines them. Always clarify whether a dentist is talking about the implants themselves or the teeth (visible portion) attached to them.
What Do Permanent Dentures Cost?
Costs vary widely depending on the type of treatment and the number of implants.
General ranges include:
- Premium removable dentures: lower cost range
- Implant dentures: higher upfront cost but more stable and cost-effective long term
- Fixed full arch implants: the highest investment, often ranging from $20,000 to 50,000 per arch in many clinics nationwide. For up-to-date pricing, please reference the Smart Arches dental implants cost guide.
Dental insurance may cover part of the treatment, especially the denture portion, but insurance rarely covers full arch implants in full.

How Long Does the Process Take?
The timeline depends on whether implant-based dentures are used. Most patients go through these steps:
1. Consultation and 3D scan
2. Any extractions or preliminary work
3. Placement of implants
4. Healing period of several months while bone fuses to the implants (a process called osseointegration)
5. A temporary denture during healing if needed
6. Final denture or permanent bridge placement
Fixed implant bridges may allow for immediate temporary teeth, but final teeth still require healing first.
Who Is a Candidate for Permanent Dentures?
Patients may be candidates if they have:
- Missing all or most teeth
- Good general health
- A strong enough jawbone, or willingness to undergo bone grafting
- A desire for better stability than traditional dentures
A 3D cone beam scan is required to determine whether bone levels are adequate for implants.
Permanent Dentures vs Snap-in Dentures vs All-on-4
Here is a simplified comparison:
Traditional dentures
Most affordable
Least stable
No implants used
Snap-in dentures
Uses 2 to 4 implants
Removable
Much more stable
Lower cost than fixed full arches
Fixed permanent dentures or All-on-4
Uses 4 to 6 implants
Does not come out
Highest chewing ability
Most expensive
Most natural feel
Patients often confuse snap-in dentures with permanent dentures, so ask your dentist whether the denture will be removable or fixed permanently in your mouth.

Which Permanent Denture Option Is Right for You?
The best choice depends on your budget, your bone health, your expectations for stability, and whether you want a removable or non-removable solution. A consultation that includes a full exam and 3D scan is the most accurate way to determine which option will work for your smile.
Permanent dentures can be life-changing, but understanding the differences between each type helps ensure you choose the treatment that fits your goals, comfort level, and long-term health.
