Yes, permanent dentures exist, and they’re one of the most popular options for replacing a full arch of missing teeth. Unlike traditional removable dentures that sit on your gums and come out at night, permanent dentures are fixed prosthetics anchored to dental implants surgically placed in your jawbone. They stay in your mouth at all times, function much like natural teeth, and typically cost between $3,055 and $7,294 per arch.
How Permanent Dentures Differ From Traditional Ones
Traditional dentures rest on your gums and are held in place by suction or adhesive. They can slip during eating or speaking, and you remove them daily for cleaning and sleeping. Permanent dentures, by contrast, are screwed or cemented onto titanium implant posts embedded in your jawbone. Only a dentist can remove them.
The clinical term you’ll hear most often is “implant-supported bridge” or “fixed implant-supported prosthesis.” These are full arches of replacement teeth, usually made from ceramic or acrylic, that attach to small connector posts sitting on top of the implants. Because the implants fuse directly with your bone over time, the result feels stable and solid in a way removable dentures never do. You bite, chew, and speak without worrying about shifting or clicking.
The All-on-4 Approach
The most common method for placing permanent dentures uses just four implants per arch. Two are placed vertically near the front of the jaw, and two are angled up to 45 degrees in the back. Angling the rear implants lets them grip into denser bone further forward, which often eliminates the need for bone grafting that older implant techniques required.
One of the biggest selling points is speed. In many cases, a temporary fixed bridge is screwed onto the implants the same day as surgery, a process sometimes marketed as “Teeth in a Day.” You leave the office with a functional set of teeth, though this initial bridge is made from acrylic and serves as a placeholder. After your jawbone fully fuses with the implants, a process that takes roughly 3 to 6 months, your dentist replaces it with a stronger, more natural-looking final prosthesis.
What the Timeline Looks Like
The full process from consultation to final teeth typically spans 4 to 8 months, depending on your healing speed and whether you need any preliminary work like tooth extractions or bone grafts. Here’s the general sequence:
- Surgery day: Implants are placed and a temporary bridge is attached. Most people take a few days to a week off for initial recovery.
- Healing period (3 to 6 months): The implants gradually fuse with your jawbone. During this time, you’re eating and functioning on the temporary bridge, though you’ll want to stick to softer foods for the first few weeks.
- Final prosthesis: Once the implants are fully integrated, your dentist takes impressions and fits the permanent bridge, which is made from more durable materials like ceramic or zirconia.
How Long They Last
Permanent dentures are a long-term investment, but they aren’t indestructible. A 10-year study published in the International Journal of Oral & Maxillofacial Implants found that full-arch ceramic bridges had survival rates around 90% at the decade mark, while acrylic-based bridges (sometimes called Toronto bridges) came in lower, around 74% to 88% depending on whether they were placed in the upper or lower jaw. Lower jaw restorations tend to perform better because the bone there is denser.
The implants themselves can last decades or even a lifetime with proper care. It’s the prosthetic teeth sitting on top that may need repair or replacement over the years, whether from normal wear, chipping, or changes in your bite.
Who Can and Can’t Get Them
Most adults with missing teeth or failing teeth are candidates, but a few factors can complicate things. Adequate jawbone density is essential since the implants need solid bone to fuse with. If you’ve been without teeth for years and your bone has deteriorated, you may need grafting first, or your dentist may use angled implants to work around thin areas.
Several health conditions can increase the risk of implant failure:
- Uncontrolled diabetes: Slows wound healing and raises infection risk, making it harder for implants to fuse with bone.
- Heavy smoking (more than 10 cigarettes a day): Nicotine restricts blood flow to the surgical site, and research consistently shows higher failure rates in heavy smokers.
- Active gum disease: The same bacteria that destroy gum tissue around natural teeth can attack implants, causing a condition called peri-implantitis.
- Severe teeth grinding: Implants lack the natural shock-absorbing cushion that surrounds real tooth roots. Grinding creates intense mechanical stress that can loosen screws, fracture crowns, or cause bone loss around implants.
- Recent radiation to the head or neck: Can impair bone healing and raise the risk of serious jawbone complications.
Age matters too, but not in the way you might expect. There’s no upper age limit for implants as long as you’re healthy enough for minor surgery. The real restriction is on the young end: implants shouldn’t be placed until skeletal growth is complete, typically age 18 or older, because a fixed implant won’t move with a growing jaw.
Cost Per Arch
A 2024 survey across all 50 U.S. states found the average cost for a full arch of implant-supported permanent dentures is roughly $3,976, with prices ranging from about $3,055 to $7,294. That covers both the surgical placement of implants and the prosthetic teeth. If you need both upper and lower arches, you can roughly double those numbers.
Dental insurance rarely covers the full cost of implant-supported restorations, though some plans contribute toward the prosthetic portion. Many dental offices offer financing through third-party lenders, letting you spread payments over several years. The upfront price is significantly higher than removable dentures, but permanent dentures don’t require adhesives, relines, or the frequent replacements that conventional dentures need every 5 to 7 years.
Cleaning and Daily Care
Permanent dentures can’t be popped out for a soak, so your cleaning routine looks more like caring for natural teeth, with a few extra steps. Brush at least twice a day with a soft-bristled toothbrush, paying extra attention to the gum line where the prosthetic meets your tissue. An interdental brush, the small cone-shaped kind, is useful for reaching under the bridge and around the implant posts where a regular toothbrush can’t go.
A water flosser is one of the most helpful tools you can own. It uses a pulsating stream of water to flush food particles and bacteria from the gaps between the bridge and your gums. Floss threaders work for the same purpose, guiding regular floss underneath the bridge to clean areas you’d otherwise miss. Finish with an alcohol-free antimicrobial mouthwash to reduce bacteria buildup. Your dentist may also recommend a specialized titanium-safe brush to clean the implant posts without scratching them.
You’ll still need professional cleanings, typically every 6 months, where your dental team can check the implants, tighten any screws if needed, and clean areas that are difficult to reach at home.
