Whether you’re considering dentures for the first time or looking to upgrade your current set, this blog will give you all the information you need to make an informed decision.
1. What Are Dentures?
Dentures are removable prosthetic devices designed to replace missing teeth and surrounding gum tissues. They restore your ability to chew, support facial muscles, improve speech, and give you a natural, confident smile.
There are several types of dentures available at Tracey Bell Clinics:
- Full Dentures – Replacing all teeth in the upper or lower jaw.
- Partial Dentures – Replacing several missing teeth while preserving remaining natural teeth.
- Overdentures – Fitted over remaining tooth roots or implants for added stability.
- Implant-Retained Dentures – Anchored to dental implants, offering exceptional fit and comfort.
Each type has its own indications, advantages, and maintenance needs, which we’ll explore in detail below.
2. Full Dentures
Full (complete) dentures are recommended when all natural teeth are missing from either the upper or lower arch—or both.
They are custom-made to sit snugly over the gums and can be crafted from different materials depending on patient preference and clinical requirements.
Advantages:
- Restore a complete smile and facial volume.
- Allow normal chewing and speech.
- Cost-effective compared to full-mouth implants.
Considerations:
- May require time to adapt to speaking and eating.
- Can become loose over time as gums and bone remodel.
- Regular maintenance is essential to avoid infections or soreness.
3. Partial Dentures
Partial dentures are designed for patients who still have some natural teeth remaining. They fill the gaps between teeth, maintaining the natural bite and preventing teeth from drifting.
These dentures usually clip onto existing teeth using discreet metal clasps or precision attachments.
Advantages:
- Preserve natural teeth, which helps maintain bone.
- More stable than full dentures.
- Usually easier to adjust to.
Considerations:
- Hygiene is crucial to avoid decay on supporting teeth.
- May require periodic adjustments.
4. Overdentures
An overdenture fits over remaining tooth roots or dental implants. Classically, they were used over retained roots treated endodontically (with root canal therapy). Today, implant-supported overdentures are more common.
Clinical situations for overdentures include:
- Patients with a few healthy tooth roots remaining, where roots can support and stabilise the denture.
- Patients unsuitable for extensive implant work but who need improved denture retention.
- Those looking for more affordable alternatives to fixed implant bridges.
Advantages:
- Improved stability compared to conventional dentures.
- Preservation of underlying bone by retaining roots or using implants.
- Enhanced chewing efficiency and comfort.
Considerations:
- Require good oral hygiene and regular dental reviews.
- Additional costs if implants are involved.
- Components (e.g. attachments) may need periodic replacement.
5. Implant-Retained Dentures
Implant-retained dentures are a modern, secure solution for patients who want the stability of implants with the flexibility of a removable denture.
They involve placing several dental implants into the jawbone, onto which the denture is anchored using special attachments.
Benefits include:
- Exceptional stability — the denture won’t slip or move during speech or eating.
- Improved bite force and chewing function.
- Reduced bone loss compared to conventional dentures.
- Slimmer, more comfortable denture design.
Considerations:
- Higher initial cost due to implant placement.
- Minor surgery is required.
- Regular implant maintenance is needed.
At Tracey Bell, we offer state-of-the-art implant systems, and treatment is fully customised to each patient’s anatomy and goals.
6. Denture Materials Explained
Different denture types use different base materials. Choosing the right material affects the denture’s comfort, longevity, and aesthetics. Here’s a closer look at the main materials we use:
A. Acrylic Dentures
Acrylic dentures are the most commonly used type, especially for full dentures. They are made from pink acrylic resin that mimics the appearance of natural gum tissue.
Advantages:
- Cost-effective and quick to produce.
- Easy to adjust and repair.
- Excellent aesthetics.
- Suitable for immediate dentures after extractions.
Disadvantages:
- Can be bulkier than other options.
- May wear down faster than metal frameworks.
- Over time, acrylic can become brittle and may break if dropped.
- Tend to need relining or replacement more often due to gum resorption.
B. Flexible Dentures (e.g. Valplast)
Flexible dentures are made from lightweight, nylon-based materials such as Valplast. They adapt comfortably to the natural contours of the mouth without rigid clasps.
Advantages:
- Comfortable and gentle on the gums.
- Highly aesthetic — no visible metal clasps.
- Lightweight and often well tolerated by new denture wearers.
Disadvantages:
- More challenging to adjust than acrylic.
- Adding teeth or making repairs is more complicated.
- Not ideal for every clinical situation (e.g. where precision fit is crucial).
- Can stain over time if not cleaned properly.
These dentures are excellent for temporary or aesthetic solutions, but careful case selection is essential.
C. Cobalt Chrome Dentures
Cobalt chrome dentures use a metal framework for strength and durability, with acrylic teeth and gum-coloured areas built on top.
Advantages:
- Superior strength and longevity — often lasting many years with proper care.
- Thinner and more comfortable than acrylic dentures.
- Excellent fit and stability due to precision design.
- Less likely to fracture.
Disadvantages:
- Higher initial cost.
- Requires more chair time and technical expertise.
- Metal framework is not easily adjustable once made.
- Not suitable immediately after extractions, as gums and bone need to settle first.
At Tracey Bell, cobalt chrome dentures are meticulously designed and fitted, ensuring optimal comfort, function, and aesthetics for long-term wear.
7. How We Take Dental Impressions for Dentures
Creating a well-fitting denture starts with accurate impressions of your mouth. At Tracey Bell, we use both traditional and digital techniques to achieve the best possible results.
