Losing a tooth - whether from decay, gum disease, trauma, or extraction - is more than a cosmetic issue. Missing teeth affect your ability to chew, your speech, and the long-term health of your jawbone. The good news is that modern dentistry offers three reliable ways to replace missing teeth, each suited to different situations.
This guide breaks down the honest pros, cons, costs, and ideal candidates for dentures, dental bridges, and dental implants.
Quick Comparison
| Dentures | Bridge | Implant | |
|---|---|---|---|
| Teeth replaced | Multiple (or all) | 1–4 | 1 or more |
| Removable? | Yes | No | No |
| Preserves bone? | No | No | Yes |
| Damages adjacent teeth? | No | Yes (crowns required) | No |
| Lifespan | 5–10 years | 10–15 years | 25+ years |
| Approx. cost (AUS) | $1,500–$4,000 | $1,800–$3,500 | $4,500–$6,500 |
Option 1: Dentures
Dentures are removable appliances that replace missing teeth and the surrounding gum tissue. They come in two main types:
- Full (complete) dentures - replace all teeth in the upper, lower, or both arches
- Partial dentures - replace one or more missing teeth when some natural teeth remain
How dentures are made
Dentures are custom-made from impressions of your mouth. The base is typically acrylic resin; the teeth are porcelain or acrylic. Partial dentures usually have metal clasps that attach to remaining natural teeth.
Pros of dentures
- Most affordable upfront option, especially for multiple missing teeth
- No surgery required
- Can be made quickly
- Easy to adjust or reline as your mouth changes over time
Cons of dentures
- Removable - must be taken out for cleaning, can feel unnatural
- Less stable than fixed options - can slip or click when eating and speaking
- Bone resorption continues - without a tooth root, the jawbone gradually shrinks, causing dentures to become loose over time and requiring relining or replacement
- Lower dentures in particular can be difficult to keep in place
- Some foods remain difficult to eat (hard, sticky, chewy items)
Ideal for
- Patients missing most or all of their teeth
- Those who need an affordable short-term solution
- Patients who are not candidates for surgery
Cost of dentures in Australia
| Type | Typical Cost Range |
|---|---|
| Partial denture | $1,200 – $2,500 |
| Full upper or lower | $1,800 – $3,200 |
| Full upper and lower | $3,000 – $6,500 |
Option 2: Dental Bridges
A dental bridge is a fixed prosthesis that fills a gap left by one or more missing teeth. It consists of one or more artificial teeth (pontics) anchored to crowns placed on the natural teeth on either side of the gap (abutments).
How a bridge is made
The teeth on either side of the gap are prepared (filed down) to support the crowns. Impressions are taken and sent to a dental laboratory, which fabricates the bridge. A temporary bridge protects the prepared teeth while the permanent one is being made. At a second appointment - usually 1–2 weeks later - the permanent bridge is fitted and cemented.
Pros of bridges
- Fixed and non-removable - functions more like a natural tooth than dentures
- No surgery required
- Generally completed in 2 appointments
- Covered by most major dental (Extras) health funds
Cons of bridges
- Requires grinding down healthy adjacent teeth to act as anchors - this is a permanent, irreversible change
- Does not prevent bone loss at the extraction site - the jawbone still shrinks because there is no root stimulating it
- Cleaning underneath the bridge (beneath the pontic) requires special flossing tools
- May need replacement after 10–15 years
Ideal for
- Patients missing one to three teeth in a row
- Those who want a fixed (non-removable) solution without surgery
- Patients who already have crowns on adjacent teeth (so no extra damage is done)
Cost of bridges in Australia
| Type | Typical Cost Range |
|---|---|
| Three-unit bridge (1 missing tooth) | $1,800 – $3,500 |
| Four-unit bridge (2 missing teeth) | $2,500 – $5,000 |
Option 3: Dental Implants
A dental implant replaces not just the crown of the missing tooth, but also the root. A titanium post is surgically placed into the jawbone, where it fuses with the bone over several months (osseointegration). A custom crown is then attached to the post.
How implants are placed
- Consultation and planning - X-rays and/or a CBCT 3D scan to assess bone volume. If bone grafting is needed, this is done first.
- Implant surgery - the titanium post is placed under local anaesthetic. Most patients are surprised at how straightforward this is.
- Healing (osseointegration) - 3–6 months for the implant to fuse with the jawbone. A temporary crown may be provided during this time.
- Crown placement - the permanent ceramic or zirconia crown is attached via an abutment.
Pros of implants
- Most natural-feeling - they look, function, and feel like natural teeth
- Preserve the jawbone - the implant root stimulates bone just like a natural tooth root, preventing the bone resorption that occurs with bridges and dentures
- Don't damage adjacent teeth - no grinding down of healthy teeth
- Longevity - the titanium post can last a lifetime; the crown typically 15–25 years
- Easier to clean - brush and floss normally
- Improved confidence - no denture adhesive, no risk of slipping
Cons of implants
- Higher upfront cost than bridges or dentures
- Surgery required - though usually done under local anaesthetic as an in-chair procedure
- Treatment time - the full process takes 4–9 months (or longer if bone grafting is required)
- Not suitable for patients with insufficient bone (without grafting), heavy smokers, or uncontrolled health conditions
Implant options for multiple missing teeth
- Implant-supported bridge - 2 implants can support a 3–4 unit bridge, avoiding the need for one implant per missing tooth
- All-on-4 / All-on-6 - a full arch of teeth supported by just 4–6 implants; transforms complete denture wearers in as little as a day
- Implant-supported denture (overdenture) - a denture that clips onto implants for dramatically improved stability
Cost of dental implants in Australia
| Procedure | Typical Cost Range |
|---|---|
| Single implant (post + crown) | $4,500 – $6,500 |
| Bone graft (if needed) | $1,000 – $2,500 |
| Implant-supported bridge (2 implants + 3 crowns) | $8,000 – $12,000 |
| All-on-4 (full arch) | $25,000 – $40,000 per arch |
Which Option Is Right for You?
| Your Situation | Likely Best Option |
|---|---|
| Missing 1 tooth, healthy adjacent teeth | Implant (if budget allows) or bridge |
| Missing 1–3 teeth, crowns already on adjacent teeth | Bridge (repurposes existing crown prep) |
| Missing most or all teeth, limited budget | Dentures |
| Missing most or all teeth, want a fixed solution | All-on-4 implants |
| Wearing loose dentures | Implant-supported overdenture |
| Bone loss at extraction site | Implant with bone graft |
The right answer depends on your specific bone structure, overall health, number of missing teeth, budget, and lifestyle priorities. The best way to decide is a consultation with your dentist, who can examine your X-rays and provide a personalised recommendation.
