Most of what you pay for in a dental bridge sits either side of the gap, not in it. A conventional bridge for one missing tooth is made of three linked units: a crown on each neighbouring tooth and a false tooth suspended between them. That is why a three-unit bridge typically costs about $3,500 to $6,500 across the Australian market, and why the condition of those neighbouring teeth shapes both the price and the long-term outlook.
Written by Dr James Tran, dentist at Lumi Dental.
A three-unit bridge is three crowns joined together
The supporting teeth are called abutments, and the replacement tooth in the middle is the pontic. Each unit is made by a dental laboratory, so the fee reflects the clinical work on each tooth as well as the lab work for every unit.
The figures below are typical Australian market ranges to help with planning. They are not Lumi Dental fees, and a firm quote is only possible after an examination and X-rays.
| Treatment | Typical market range |
|---|---|
| Single crown | About $1,500 to $2,500 |
| Conventional three-unit bridge | About $3,500 to $6,500 in total |
| Single implant with crown (for comparison) | About $4,000 to $7,000 |
Resin-bonded and implant-supported bridges are priced differently, depending on the design, the number of units and, for implant bridges, the number of implants and any bone grafting. Bridges covering longer gaps cost more because there are more units to make.
Four designs, each with its own trade-offs
| Design | How it is held | Often suits | Main trade-off |
|---|---|---|---|
| Conventional | Crowns on the teeth both sides of the gap | A gap with sound teeth on both sides, front or back | Both neighbours are reshaped permanently |
| Cantilever | A crown on one side only | Low-load areas, such as a small front tooth | One tooth carries all the load |
| Resin-bonded (Maryland) | Thin wings bonded to the back of the neighbouring teeth | Front teeth, or a younger patient waiting until an implant is possible | Little drilling, but can come unstuck under heavy biting |
| Implant-supported | Two or more implants instead of natural teeth | Several missing teeth in a row, or weak neighbouring teeth | Surgery, a longer timeline and a higher fee |
A bridge is not the only answer to a gap. Our guides on a bridge versus a partial denture and implant, bridge or denture lay out the alternatives.
What adds to the bill
Work needed before the bridge is the most common reason a final cost lands above the headline range. A supporting tooth may need a root canal, a core build-up or a new filling first, or the gums may need treatment. Those items are charged separately. Material choice matters too: full zirconia and layered porcelain are priced differently from porcelain fused to metal. Ask for an itemised written treatment plan with fees that lists every tooth involved, the material, and any preparatory work, so there are no surprises.
From planning to fitting
A conventional bridge usually takes two or three visits over a few weeks. The planning appointment covers your medical history, X-rays, photographs and a scan, and a discussion of materials. Sometimes a 3D X-ray is used to check the bone and roots.
At the preparation visit, the supporting teeth are numbed and shaped so the crowns can fit over them. The prepared teeth are scanned and a temporary bridge is fitted while the final one is made. At the fitting visit, the temporary comes off and the new bridge is tried in, checked for colour, fit and bite, adjusted and cemented. A short review a few weeks later is common.
Implant-supported bridges take longer, because the implants need time to join with the bone before the bridge can be attached. If a lab piece does not fit perfectly at try-in, it may be sent back; our article on why lab work sometimes gets remade explains what that means for your timeline.
Sensitivity afterwards usually settles
Because local anaesthetic is used for the preparation, the appointment itself should not hurt. The supporting teeth can be sensitive to cold or pressure for a few days afterwards, and over-the-counter pain relief used as directed on the label is usually enough. If sensitivity lasts more than a couple of weeks, or biting on the bridge hurts, see your dentist. The bite may need a small adjustment, or a supporting tooth may need further checks.
Survival is high, and the supporting teeth carry most of the risk
A systematic review comparing different types of bridges (Pjetursson and colleagues, Clinical Oral Implants Research, 2007) estimated 10-year survival at about 89% for conventional tooth-supported bridges, 80% for cantilever bridges and 87% for bridges supported only by implants. For conventional bridges, the most common problems were biological: decay in a supporting tooth and loss of the tooth’s nerve. Implant-supported bridges had more technical problems, such as chipped porcelain and loose screws.
Material also plays a part. A later review (Pjetursson and colleagues, Dental Materials, 2015) estimated five-year survival of about 94% for metal-ceramic bridges, a little higher than for the all-ceramic bridges in the included studies, although for most all-ceramic types the difference was not statistically significant.
Since decay under a supporting crown is a leading cause of failure, daily cleaning under the pontic matters more than anything else. A floss threader, a thicker floss designed for bridges, or a small interdental brush all work, and your dentist or OHT can show you the technique.
Bridge or implant for one missing tooth
For a single gap, both are often reasonable. An implant replaces only the missing tooth and leaves the neighbours untouched, which makes it the more conservative choice when the bone is adequate and surgery is suitable for you. A bridge can make more sense when the neighbouring teeth already have large fillings and would benefit from crowns anyway, when bone is limited and grafting is not wanted, when there are medical reasons to avoid surgery, or when treatment needs to be finished sooner. For several missing teeth in a row, an implant-supported bridge avoids putting a long span on natural teeth.
How bridges are planned at Lumi Dental
Bridges are part of everyday general and restorative care at Lumi Dental. Planning uses a 3D intraoral scanner and, where needed, the Orthophos 3D X-ray, and the practice has an in-house lab. Every option for the gap is discussed, including leaving it if that is reasonable, and you will usually receive an itemised written treatment plan, often by email, before any tooth is prepared. Health fund claims can be made on the spot through HICAPS. Read more about crowns and bridges at Lumi Dental.
Questions about bridges
Will my health fund cover a bridge?
Many extras policies that include major dental pay part of the cost of crowns and bridges, usually within an annual limit. The amount varies widely, so ask for the item numbers on your quote and check them with your fund before treatment.
Does a bridge harm the supporting teeth?
Shaping teeth for a conventional bridge is permanent. When the bridge fits well and is cleaned carefully, the supporting teeth can stay healthy for many years, but decay under the crowns and nerve problems are the most common complications, which is why some people with healthy neighbouring teeth choose an implant instead.
Can I have a bridge if I grind my teeth?
Usually, yes, though a custom night guard is often recommended. Heavy grinding is a common reason porcelain chips.
How soon after an extraction can a bridge be fitted?
The gum and bone need time to heal and reshape first, so the final bridge is usually made some weeks to months after the extraction. A temporary bridge or a removable plate can fill a visible gap in the meantime.
