For a suitable single-tooth site. Imaging and site preparation may be extra.
Missing-tooth comparison
Treat the gap without ignoring the neighbouring teeth.
A single implant supports its own crown through the bone. A conventional bridge uses teeth beside the gap as anchors. The choice depends on those teeth, the bone and gum at the gap, surgery, timing, cleaning, and future repair.
Uses two supporting teeth to replace one tooth between them.
Healthy adjacent teeth and an already-restored pair lead to different tradeoffs.
Implants require surgery and integration. Conventional bridges require irreversible preparation of supporting teeth. Neither option is maintenance free or expected to last for life.
Side by side
One treats the site. One recruits neighbouring teeth.
The similar starting prices describe different biological work. Implant extras can include imaging, extraction, grafting, or a temporary tooth. Bridge cost depends on span, supporting teeth, material, and whether those teeth need other care.
| Compare | Single implant and crown | Three-unit conventional bridge |
|---|---|---|
| Support | Implant fixture placed in bone supports its own crown | Two adjacent teeth support the replacement tooth |
| Starting price | From $4,500 | From $4,800 |
| Surgery | Implant surgery is required | No implant surgery, but supporting teeth are prepared |
| Adjacent teeth | Usually not prepared for the implant crown | Prepared irreversibly as bridge retainers |
| Typical timing | Often several months including integration, but varies | Often several weeks after tooth and gum assessment, but varies |
| Cleaning | Clean around the implant crown and gum margin | Clean under the joined replacement tooth with threaders or interdental aids |
| Indicative longevity | Can remain serviceable for 20 years or longer, but varies | Often 10 to 15 years, but varies |
| Future repair | Crown, screw, or implant complications can require care | Porcelain, cement, decay, nerve, or supporting-tooth problems can affect the whole bridge |
Case selection
The neighbouring teeth can decide the direction.
An implant may be discussed
- Healthy neighbouring teeth that would otherwise need preparation
- A suitable bone and gum site or an acceptable grafting pathway
- Medical and behavioural factors compatible with surgery and healing
- A patient willing to accept a longer staged process
A bridge may be discussed
- Adjacent teeth already need crowns or major restoration
- Implant surgery is unsuitable or not preferred
- The gap and anchor teeth can support a cleansable bridge design
- A shorter non-implant pathway is important
Another path may be discussed
- A removable partial denture for a less invasive or lower initial cost option
- Orthodontic space closure in selected cases
- Monitoring or accepting the space where function and movement risk allow
- Specialist review for complex bone, gum, bite, or prosthetic needs
Illustrative scenarios
The gap alone does not make the decision.
Implant may preserve neighbours
One missing tooth between healthy, unrestored neighbours
A suitable implant can replace the gap without preparing adjacent teeth, but site anatomy, surgery, cost, and healing still matter.
Bridge may combine needs
The teeth beside the gap already need crowns
If both neighbours genuinely require full coverage and can support a cleansable span, a bridge may restore them and the gap in one plan.
Broaden the comparison
Limited bone, medical complexity, or several gaps
Grafting, specialist care, a removable denture, a combination plan, or no replacement may deserve consideration.
Limits and risks
Both options move future risk somewhere.
Implant
- Surgical bleeding, infection, nerve, sinus, and grafting risks depend on the site.
- The implant may fail to integrate or lose support later.
- Smoking, gum disease, medical factors, bite, and cleaning affect risk.
- The crown or components may need repair or replacement.
Bridge
- Supporting teeth require irreversible preparation.
- Decay, nerve problems, fracture, or gum disease can affect an anchor tooth.
- Cleaning under the bridge requires additional technique.
- A problem with one support can affect the full restoration.
No replacement
- Leaving a gap may be reasonable in selected cases.
- Teeth can tip, drift, over-erupt, or change bite, but the pattern is individual.
- Function, appearance, age, and future treatment plans should be reviewed.
Before choosing
Six questions for the plan.
- 01
Do the neighbouring teeth need crowns anyway?
Avoid preparing healthy teeth without a reason, but do not ignore genuine restorative needs beside the gap.
- 02
What does the CBCT show at the implant site?
Bone, sinus, nerve, gum, and three-dimensional space affect surgery and grafting.
- 03
What is included in each starting price?
Compare imaging, extraction, grafting, temporary teeth, abutment, final crown or bridge, reviews, and future maintenance.
- 04
How will I clean the restoration?
Daily access and technique affect gum health, decay risk, and longevity.
- 05
What is the likely failure mode?
Compare implant integration and component risks with bridge anchor-tooth, decay, nerve, and span risks.
- 06
Is a removable option or no replacement reasonable?
A fixed restoration should be compared with all clinically suitable paths.
Cost beyond the first restoration
Maintenance belongs in the comparison.
Different future expenses
An implant crown starts from $1,800 if future replacement is required. Surgical or implant complications are case-specific.
A bridge may need repair or full replacement if porcelain, cement, decay, fracture, gum health, or an anchor tooth fails. The condition of each supporting tooth affects whether another bridge remains possible.

Common questions
The gap, the site, and the supporting teeth.
Can I get an implant years after losing a tooth?
Often, but the bone and gum at the site may have changed. A CBCT can assess available bone and nearby anatomy. Grafting may be needed, and some sites or medical circumstances may make a bridge, denture, referral, or no replacement more appropriate.
Is an implant more painful than a bridge?
An implant involves surgery under local anaesthetic and commonly causes temporary soreness, swelling, or bruising afterwards. A bridge avoids implant surgery but requires irreversible preparation of supporting teeth and can cause temporary sensitivity. Experiences and risks vary.
What happens if a bridge fails?
The bridge and supporting teeth need assessment. A new bridge may be possible when the abutment teeth remain restorable. Decay, fracture, gum problems, or nerve involvement can change the plan and may lead to root canal treatment, extraction, implants, or removable replacement.
Can a bridge be converted to an implant later?
Sometimes. The gap, bone volume, gum condition, bite, and supporting teeth need reassessment after bridge removal. Grafting or treatment of the adjacent teeth may be required before an implant is possible.
Are there options other than an implant or bridge?
A removable partial denture, orthodontic space closure in selected cases, accepting or monitoring the space, and different implant-supported designs may be considered. Suitability depends on function, appearance, bite, age, health, and the position of the gap.
Which option lasts longer?
Implants and bridges can both provide long service, but lifespans vary. A single implant may remain serviceable for 20 years or longer, while a tooth-supported bridge often lasts about 10 to 15 years. Gum health, decay, smoking, bite, cleaning, material, and maintenance affect both.
Does health insurance cover either option?
Some extras policies contribute towards major dental, implant surgical, or restorative items. Waiting periods, annual limits, exclusions, and benefit amounts vary. Ask your fund to assess the item numbers in the written quote.
A considered first step
Compare the site and the neighbouring teeth in one plan.
We can assess bone, gum, bite, supporting teeth, timing, maintenance, and alternatives before providing staged written costs.
