The main difference between partial and full dentures is the number of natural teeth being replaced. Partial dentures are designed for people who still have some natural teeth, while full or complete dentures replace all natural teeth in an upper or lower arch. The appropriate type depends on how many teeth are missing, the condition of remaining teeth and the overall treatment plan.
What Are Partial Dentures?
Partial dentures replace one or more missing teeth while some natural teeth remain.
They may use supporting teeth to help hold the appliance in position and can restore some chewing and speaking function.
The Canadian Dental Association describes partial dentures as removable appliances that replace missing teeth and are held in place using nearby natural teeth.
What Are Full Dentures?
Complete dentures replace all natural teeth in the upper or lower arch.
They are designed to restore functions such as:
- Chewing
- Speaking
- Supporting facial appearance
- Replacing missing teeth
The Canadian Dental Association notes that complete dentures are removable and can take time to adjust to.
Lotus Family Dental’s denture service currently describes full dentures, partial dentures and overdentures as available denture categories.
Partial vs Full Dentures: Key Differences
| Feature | Partial Dentures | Full Dentures |
| Natural teeth remaining | Some | None in the treated arch |
| Purpose | Replace selected missing teeth | Replace all teeth in an arch |
| Support | May use remaining natural teeth | Relies on fit and oral anatomy |
| Removal | Usually removable | Usually removable |
| Adjustment period | Can vary | Can require an adjustment period |
| Maintenance | Clean appliance and remaining teeth | Clean appliance and gums |
The correct choice is based on your actual dental condition rather than simply the number of teeth missing.
What Are Overdentures?
Overdentures are another denture option.
The Canadian Dental Association describes an overdenture as a removable denture that fits over remaining natural teeth or dental implants.
Lotus Family Dental also identifies overdentures among its denture options.
Whether an overdenture is appropriate depends on the supporting teeth, gums, bone and overall treatment plan.
How Do You Know Which Type You Need?
Several factors may affect the decision.
1. How Many Teeth Are Missing?
If some natural teeth remain and can provide useful support, a partial denture may be considered.
If all teeth in an arch are missing, a complete denture may be considered.
2. Are the Remaining Teeth Healthy?
The condition of the remaining teeth matters.
Your dentist may assess:
- Tooth strength
- Decay
- Gum health
- Existing restorations
- Bite
- Bone and supporting structures
3. How Does the Denture Fit With Your Lifestyle?
Patients may also want to discuss:
- Speech
- Eating habits
- Appearance
- Cleaning requirements
- Removal at night
- Adjustment appointments
4. Does the Denture Need Future Adjustments?
Your mouth changes over time, which can affect how a denture fits.
The CDA notes that dentures may need adjustment or relining as the mouth changes.
How Should Dentures Be Cared For?
Both partial and complete dentures require regular cleaning.
The Canadian Dental Association recommends:
- Cleaning dentures daily
- Removing them at night
- Cleaning natural teeth and gums
- Soaking dentures appropriately
- Avoiding hot water that could distort the appliance
- Having dentures checked regularly

What Questions Should You Ask Before Getting Dentures?
Before choosing a denture option, ask:
- How many teeth need to be replaced?
- Are my remaining teeth healthy enough to support a partial denture?
- Would a complete denture be necessary?
- Are overdentures appropriate in my situation?
- How will the appliance affect eating and speaking?
- How often might adjustments be needed?
- What cleaning routine should I follow?
- What replacement or repair options are available later?
These questions can make the consultation more productive and help you understand why one type may be recommended over another.
FAQs
Are partial dentures better than full dentures?
Neither is universally better. They are designed for different situations. Partial dentures are used when natural teeth remain, while full dentures replace all teeth in an arch.
Can partial dentures replace one tooth?
They can be designed to replace one or more missing teeth, depending on the clinical situation.
Are full dentures removable?
Yes. Conventional full dentures are generally removable.
How long do dentures last?
There is no fixed lifespan that applies to every denture. Fit, wear, oral changes and maintenance can affect when an appliance needs adjustment, repair or replacement.
Can dentures feel uncomfortable at first?
An adjustment period is possible. Persistent pain, sores or poor fit should be discussed with a dental professional.
