How much should a white tooth filling cost?
A white tooth filling in Canberra usually costs $150 to $400. A small filling on one surface of a tooth sits near the bottom of that range. A larger white filling covering two or more surfaces runs higher, up to around $450. White fillings cost more than silver ones because they take more skill and time to place. For big repairs, a lab-made white filling (a porcelain inlay or onlay) costs a lot more, from about $650 upwards.
White filling versus silver: the price difference
Most people asking about a white filling really want to know two things. What does it cost, and why is it dearer than the silver kind? Here is how they compare in Canberra.
Filling | Typical Canberra cost | How it looks |
White composite, 1 surface | $150 to $250 | Matches the tooth |
White composite, 2 or more surfaces | $250 to $450 | Matches the tooth |
Silver amalgam | $80 to $150 | Grey metal |
Porcelain or ceramic inlay/onlay | $650 to $2,000 | Matches the tooth, for large repairs |
So a white filling costs you roughly $70 to $250 more per tooth than the silver equivalent. On a front tooth or anywhere that shows when you smile, most people happily pay the difference. On a hidden back molar, the choice is more about longevity than looks.
There are two kinds of white filling
This is the part most price pages leave out, and it explains the wide range. Not all white fillings are the same.
A direct composite filling is the everyday white filling. Your dentist places soft resin straight into the cleaned cavity, shapes it, and sets it hard with a light, all in one visit. This is the $150 to $450 option.
A porcelain or ceramic filling (an inlay or onlay) is made in a lab and bonded in at a second visit. It is used when the cavity is too big for direct composite to hold well. It is much stronger and lasts longer, but it costs far more, often $650 to $2,000. If a dentist quotes you well over $500 for a "white filling," they usually mean this lab-made type, not a standard one.
Why white fillings cost more to place
Silver amalgam is quick. You pack it in and it sets. Tooth-coloured composite asks a lot more from the dentist. The tooth has to be kept perfectly dry, the resin is built up in thin layers, each layer is light-cured, and the final shape is trimmed and polished to blend in. That extra chair time is the main reason for the higher fee. The material itself also costs more than amalgam.
Two other things move the price within the white range: how big the cavity is, and how many surfaces of the tooth it touches. Dentists quote per surface, so a filling wrapping around two or three sides costs more than a single small spot.
Are white fillings worth the extra cost?
For most people, yes, especially on teeth that show. Here is the honest picture, though.
Modern composite is strong and typically lasts 5 to 10 years with good care. Years ago silver fillings clearly outlasted white ones. That gap has narrowed a lot, but on a large filling in a big molar, a very durable option like porcelain or a crown can still be better value over time, even though it costs more upfront. A good dentist will say when that is the case rather than push the pricier option.
The upsides of white are real. It bonds to the tooth so less healthy tooth is removed, it has no mercury, and no one can tell it is there. Whether that is worth the extra is a personal call, so ask your dentist to talk it through before you decide.
Keeping the cost down
A few things genuinely help. Most extras policies pay a rebate towards a general composite filling, so check what your health fund covers before you book. Catching decay early matters too, since a small filling always costs less than a large one, which is a good reason not to skip your regular check-up. And prevention beats any filling: Canberra's fluoridated tap water helps, and fissure sealants can protect deep grooves before decay starts.
Frequently asked questions
How much should a white tooth filling cost? In Canberra, a standard white (composite) filling usually costs $150 to $400. Small single-surface fillings are cheaper, larger multi-surface ones cost more, and lab-made porcelain fillings for big repairs start around $650. The size of the cavity and the material decide the final price.
Are white fillings worth the extra cost over silver? For most people, yes. White fillings look natural, bond to the tooth, and contain no mercury. The extra is usually $70 to $250 per tooth. On large back molars, a stronger option can sometimes be better long-term value, so ask your dentist.
Does private health insurance cover white fillings? Usually in part. Most extras policies pay a set rebate towards a general composite filling, and you cover the gap. The rebate depends on your fund and level of cover, so confirm your limits before treatment.
