Dentures Complete Guide
Types, Costs, and Implant Overdentures

The idea that 'dentures are uncomfortable' is outdated. With advances in precision lab technology and implant-supported dentures, a well-made denture can restore about 70–80% of natural chewing power. Prosthodontists at Seoul BD Dental have organized everything about partial dentures, complete dentures, and implant overdentures.

01What is a denture

A denture is a removable prosthetic device that replaces missing teeth and the surrounding gum tissues.

The medical term for a denture is removable denture. Because patients can insert and remove it themselves, it differs from fixed prosthetics such as crowns and dental bridges that are cemented in place, and from dental implants anchored in the bone.

A denture is not simply a 'tool to fill a gap.' Over time, tooth loss leads to jawbone resorption, changes in facial shape, and diminished speech and chewing function. A well-designed denture enables restoration of chewing function, speech, and facial profile (contour)simultaneously.

Main components of a denture

02Comparison of denture types

Based on the number of remaining natural teeth, gum condition, and your budget, there are five main denture options.

TypeWho it's forProsCons
Complete Denture (Complete Denture)No natural teeth remaining (edentulous)Most affordable; non-invasiveChewing power about 20~30% of natural teeth; lower stability
Partial Denture (Partial Denture)When some natural teeth remainMore stable than a complete denture; preserves natural teethClasps (hooks) may show; may stress natural teeth
Precision-Attachment Partial DentureFor partial-denture patients who prioritize estheticsNo visible clasps; excellent stabilityHigher cost (1,500,000~3,000,000 KRW; approx. $1,095~$2,190); crown(s) may be needed on natural teeth
Implant Overdenture (2~4 Dental Implants)For edentulous patients whose complete denture is loose or unstableChewing power about 60~70% of natural teeth; stability greatly improvedAdditional Dental Implant cost (3,000,000~6,000,000 KRW; approx. $2,190~$4,380)
Implant-Supported Fixed Prosthesis (All-on-4/6)For patients seeking full restorationChewing force 70~80% of natural teeth; feels like your natural teethCost: highest (per arch 15–30 million KRW; approx. $10,950–$21,900)

Denture vs. Dental Implant Comparison

Dental implants may seem superior in every way, but depending on the patient’s condition, dentures are often more suitable.

Implant Overdenture — a middle-ground solution

Using 2~4 implants to solve the biggest complaints of complete dentures (rocking/looseness) is Implant OverdentureIt is. The cost is about 1/3~1/5 that of a Full-Mouth Implant, and chewing force is 2~3 times that of a conventional denture. For patients age 65 and older, Korean NHIS covers 2 implants with a 30% patient share, making it the most cost-effective option.

03Denture Costs (2026)

For patients age 65 and older, dentures are covered by Korean NHIS with a 30% patient share.

Non-covered (out-of-pocket) (under 65 or outside Korean NHIS)

Eligibility for Korean NHIS denture coverage

If you are age 65 or older and have partial or complete edentulism after registering with the National Health Insurance Service, once every 7 years coverage is available. If lost or damaged, remaking within 7 years is 100% out-of-pocket; exceptions are recognized for events such as natural disasters or oral cancer surgery. Implant Overdenture coverage is limited to 2 implants per lifetime.

Costs vary by clinic, materials used, and denture precision. Your exact out-of-pocket amount will be explained after diagnosis during consultation.

04Denture fabrication process

Denture fabrication typically requires 4–6 visits over about 3–6 weeks.

Visit 1: Diagnosis and preliminary impressions (about 30–40 min)

Oral examination, panoramic X-ray, and assessment of your gums. If any areas need extraction based on the condition of your existing teeth and gums, we treat those first and begin full fabrication after the gums heal (about 4–8 weeks). A primary alginate impression is taken to make your custom tray.

Visit 2: Definitive impressions (about 30–40 min)

Using the custom tray made at visit 1, we take definitive impressions. We perform the "border molding" process to capture the movement of the muscles around the gums—this is the most important step for determining denture stability and seal.

Visit 3: Bite registration (about 30 min)

Using a wax rim, we determine the precise maxilla–mandible relationship, lip support, smile line, and midline. Because this step directly affects your facial appearance and speech, the prosthodontist's clinical experience is one of the most important factors.

Visit 4: Try-in (about 30–40 min)

We place a wax trial denture with the artificial teeth set in and check facial appearance, speech, bite, and esthetics. You review it in a mirror, and we revise it to reflect your feedback. Thorough revisions at this stage lead to higher satisfaction with the final result.

Visit 5: Final placement (about 30–40 min)

We deliver the completed denture, adjust the bite, check for sore spots, and provide instructions on use and care.

After visit 6: Post-delivery adjustments (about 15–30 min, 2–4 visits)

Return regularly about 1, 2, and 4 weeks after delivery for sore-spot adjustments and fine bite tuning. As your gums adapt to the new denture, they change subtly, so follow-up adjustments are essential.

Why can't it be done "all at once, quickly"?

Each stage requires 1–2 weeks of lab fabrication time. And because gums are living tissue, patients need time to adapt and be adjusted at each step to achieve the best final result. Ads that promise "made in 3 days" can differ greatly in post-delivery fit and precision, so please choose carefully.

05Denture adjustment period and discomfort

On average, it takes 2–4 weeks to fully adapt to a new denture; in some cases it can take as long as 2–3 months.

Typical course during the adjustment period

TimeframeCommon experienceCare tips
Days 1–3Foreign-body sensation, excessive saliva, awkward speech, some sore spotsSoft foods; cut food into small pieces
Days 4–7Sore spots develop → first adjustment neededDon't wait—come in for an adjustment
2~4 weeksChewing function gradually recovers; speech adaptsBiting large apples or tough meats is still difficult
1~3 monthsAdapted to most foods; use feels more naturalDevelops a fully "my own" feel

Common challenges and solutions

Foods to avoid (early adaptation period)

Warning signs you should not ignore

Mild foreign-body sensation is normal at first, but if you have persistent, significant pain in a specific area or the same spot becomes raw and ulceratedyou need a pressure-spot adjustment. Enduring it will make the gums break down more and delay healing. During the first 2 weeks, expect 1~2 adjustment visits per week

06Denture care

Dentures require more meticulous care than natural teeth. Poor care can cause denture stomatitis, bad breath, and accelerate jawbone resorption

Daily care

Care to do 1~2 times per week

What not to do

Regular checkups

07Implant Denture (Implant Overdenture)

A prosthesis that adds 2–4 implants to an existing complete denture to greatly improve stability and chewing ability.

Implant Overdentureis one of the most recommended prosthetic options for fully edentulous patients. Complete dentures rely only on suction and gum shape, so they loosen and wobble over time; implants anchor the prosthesis directly to the jawbone, significantly improving stability.

Differences by number of implants

TypeStabilityChewing efficiencyCost (per arch)
Complete denture (0 implants)Low20–30% of natural teethAbout 1,000,000–1,500,000 KRW (approx. $730–$1,095)

Benefits of an Implant Overdenture

Drawbacks and considerations

If your parent can’t chew because their complete denture is unstable

Over 60% of complete denture wearers say, “It’s hard to chew.” As jawbone resorbs over time, the denture becomes looser; the most cost-effective solution then is an Implant Overdenture with 2 Dental Implants. For those 65+, Korean NHIS covers up to 2 implants with a 30% patient co-pay. With an average personal co-pay of 700,000 KRW (approx. $511), this option can greatly improve your eating quality.

08Frequently Asked Questions

We’ve compiled the questions patients ask most about dentures.

Q.Can dentures be covered by Korean NHIS if I’m under 65?

As a rule, coverage applies only to those 65 and older. However, if you have multiple tooth loss due to oral cancer or maxillofacial trauma, you may qualify for a special coverage exception—please consult us during your visit. For the general population under 65, treatment is non-covered (out-of-pocket).

Q.I’m having a very hard time adjusting to my denture. Can I switch to implants?

Yes, it’s possible. However, not everyone can switch to implants right away; it depends on your jawbone condition and overall health. If the bone has resorbed significantly, a Bone Graft (GBR) may be needed. Also, rather than jumping straight to full implants, an Implant Overdenture (2–4 Dental Implants + Denture)offers a good balance of cost, adaptation, and function. We recommend a thorough evaluation first to assess your individual condition.

Q.Can I sleep with my denture in?

It’s not recommended. Your gums need rest at night, and sleeping with dentures can cause denture stomatitis (Candida yeast infection), accelerate jawbone resorption, and lead to bad breath. After brushing before bed, remove your denture and soak it in water or a denture storage/soaking solution—this is the standard recommendation.

Q.My denture keeps coming loose—can I use adhesive (denture glue)?

It can be used as a temporary measure, but denture adhesive is not a definitive solution. Frequent loosening is a sign that your jawbone has resorbed and the denture has become loose. Visit your dentist for Relining to refill the inside of the denture to match your gums; if resorption is severe, consider a remake or converting to an Implant Overdenture.

Q.How long does a denture last?

With good care, the average lifespan is 5–7 years of use. However, because jawbone resorbs over time, even an intact denture can become loose against the gums, requiring relining or a remake. The 7-year Korean NHIS coverage interval is a practical benchmark for average lifespan.

Q.How is an Implant Overdenture different from a standard Dental Implant?

After placing the implant, if we put a fixed prosthesis (Crown · Dental Bridge)on top, that’s a standard Dental Implant, a removable Denturethen it’s an Implant Overdenture. An overdenture can be taken out after meals for cleaning, making hygiene easier, and because it uses fewer implants, the cost is lower. However, fixed prostheses feel more stable—closer to natural teeth. We decide based on the patient’s jawbone condition, budget, and ability to maintain oral hygiene.
