Implant vs bridge — what each treatment actually involves
| Factor | Implant | Bridge |
|---|---|---|
| What it is | Titanium post inserted into jawbone, topped with a crown | Three-unit crown spanning the gap, anchored to adjacent teeth |
| Effect on adjacent teeth | None — stands alone | Adjacent teeth ground down to support anchors — permanent |
| Bone preservation | Yes — stimulates bone like a natural root | No — bone at gap site gradually resorbs over time |
| Procedure duration | 3–9 months total (healing time required) | 2–4 weeks (two appointments) |
| Typical lifespan | 15–25+ years; can last lifetime with care | 10–15 years before replacement typically needed |
| AU cost (single tooth) | $4,500–$7,000+ | $3,000–$5,000 |
| Feel and function | Closest to natural tooth | Good — but slight difference in cleaning routine |
| Cleaning | Brush and floss normally | Requires floss threaders or water flosser under bridge |
The cost calculation most patients miss
A bridge at $4,000 that needs replacing twice in 30 years costs $12,000 and involves preparing healthy adjacent teeth twice more. An implant at $6,000 placed once and maintained well may cost less over the same period — and the adjacent teeth remain intact throughout. Ask your dentist to walk you through the 20-year scenario for both options.

Prepare
AU costs and what your health fund actually covers
AU private health funds treat implants and bridges differently — and the distinction is not always clear in policy documents.
| Component | Implant | Bridge |
|---|---|---|
| Crown (prosthetic tooth) | Usually covered under Major Dental — check item number 615 | Usually covered under Major Dental — item numbers 613/643 |
| Implant post (titanium fixture) | Rarely covered — most funds exclude the post itself | N/A |
| Abutment (connecting piece) | Sometimes covered — varies by fund | N/A |
| Bone graft (if needed) | Rarely covered | N/A |
| Waiting periods | Typically 12 months for Major Dental | Typically 12 months for Major Dental |
Before committing: Call your health fund with the specific item numbers your dentist has quoted. Ask: "What do you pay for each of these item numbers, and what is my annual Major Dental limit?" The gap between the fund's schedule fee and your dentist's fee is your out-of-pocket — your dentist's overall quote figure does not change based on what your fund pays.
Annual limits apply: Most funds cap Major Dental benefits at $1,000–$2,000 per year. If your implant costs $6,000 and your fund pays $800 toward the crown, your out-of-pocket is $5,200 — not $6,000 minus your full annual limit. Confirm this calculation with your fund before treatment begins.

Assess
Are you suitable for an implant?
Not everyone is a candidate for implants. These are the main factors your dentist will assess before recommending one.
Factors that support implants
- Adequate bone density and volume at the site
- Healthy gums — no active periodontal disease
- Non-smoker or willing to stop during healing
- Well-controlled systemic health
- Healthy adjacent teeth (no existing crowns)
- Willingness to commit to 3–9 month process
Factors that complicate implants
- Bone loss at site (may need grafting first)
- Uncontrolled diabetes
- Active gum disease
- Heavy smoking
- Bisphosphonate medication (osteoporosis)
- Previous head/neck radiation treatment
Bone grafting note: If there has been significant bone loss since the tooth was extracted, bone grafting may be possible before implant placement — adding 3–6 months and $1,500–$3,000+ to the total cost. This is not always necessary. A CBCT scan (3D dental X-ray) gives a definitive picture of available bone. Ask whether this is included in the consultation or quoted separately.
R
Decide
The decision guide — which option fits your situation
| Your situation | Likely better option |
|---|---|
| Adjacent teeth are healthy with no existing work | Implant — avoid grinding healthy teeth for a bridge anchor |
| Adjacent teeth already have crowns or large fillings | Bridge may make sense — anchors are going on teeth that need crowns anyway |
| Budget is the primary constraint right now | Bridge — lower upfront cost, though higher long-term |
| You want the result that feels most like a natural tooth | Implant |
| You need treatment completed quickly (wedding, event) | Bridge — 2–4 weeks vs 3–9 months |
| Tooth extracted recently (within 6 months) | Implant — less bone loss, may avoid grafting |
| Tooth gap has been present for years | Assess bone first — grafting may be needed for implant; bridge may be simpler |
| Confirmed insufficient bone, grafting not wanted | Bridge |
The question to ask your dentist
"If it were your tooth and these were your circumstances, which would you choose — and why?" A dentist who answers this directly, with reasoning specific to your situation, is giving you clinical judgment. One who deflects to "it's your decision" without walking you through their thinking may be avoiding accountability. You want both the recommendation and the reasoning.
