At Richmond Fine Dentistry we believe in using quality dental materials and keeping in tune with the latest dental techniques and philosophies.
Like painting, surface preparation is paramount and we spend time meticulously preparing the tooth for the restoration. Similarly the finish is important and we ensure the filling is well contoured, polished and you are able to floss effectively.
We offer a full range of tooth coloured restorations:
Dental caries, or dental decay, is a common disease, which causes cavities and discoloration of both permanent and deciduous or “baby” teeth. As the disease progresses in a tooth it becomes weaker and its nerve may be damaged.
Dental decay occurs when bacteria in the mouth make acid which then dissolves the tooth. Bacteria only produce this acid when they are exposed to sugar. If you have a sensible diet, a good flow of saliva, a cleaning routine and your teeth get an appropriate fluoride exposure, you are less likely to get decay.
You can prevent decay by:
Saliva is the best natural defence against decay. The acid from bacteria can be neutralised by saliva. A reduced flow of saliva (*dry mouth) can increase your risk of decay.
Causes of Dry Mouth (Xerostomia)
In the mouth, there is a constant demineralisation (strengthening minerals like calcium and fluoride being dissolved by acids) and remineralisation (strengthening minerals being re-deposited on the teeth from saliva). If your demineralisation is happening at a greater rate than remineralisation, you get loss of tooth substance.
If your mouth is acidic a good deal of the day from, say, excessive and constant intake of acidic soft drinks or constant sugar intake, then the demineralisation wins and you have problems.
If you are careful with the diet, then your saliva is more neutral and you will get good remineralisation to constantly repair the teeth.
Early dental caries is reversible. Minerals can be deposited back onto the tooth surface if you can modify your diet and oral hygiene. We can treat early areas of caries with topical fluoride, and if you are careful with your diet and cleaning no other treatment may be required.
A more advanced area of dental caries will require a "filling" or restoration. We will remove the damaged and infected soft tooth structure and repair the tooth. It is important to have this done as early as possible to preserve the strength of the tooth and prevent bacteria damaging the tooth pulp.
It is very important to listen to your dentist’s advice on how to eliminate the cause of your caries. Don’t think that just fixing a cavity will stop the disease from occurring in other areas of the mouth.
Other ways you may help prevent dental caries with your diet are:
Ceramic technology can be used to create highly aesthetic inlays, onlays, veneers and crowns. Once the prepared tooth has been scanned with a camera, the dentist designs the crown or inlay on the computer. Subsequently, a milling machine cuts the restoration from an industrially prefabricated ceramic block and your dentist will directly insert the crown in your mouth.
Ceramics meet the highest aesthetic expectations and are biocompatible. Ceramics do not cause any allergic or undesired reactions, such as possible discolorations of the mucus membranes or change in taste. Therefore, they are called biocompatible. Ceramic restorations do not have metal core. Therefore, light can shine through the restorations as it does in natural teeth. In addition, the adjoining gum will show no dark metal edges when this technology is used crowning teeth. Ceramic material is colour-fast and wear resistant. In addition the low heat conduction protects the dental nerve, which is very sensitive to temperature changes.
Composite resin fillings (white)
These are white or tooth coloured fillings which are made of a plastic material mixed with small glass particles and can be used on all teeth.
Bonding is useful for improving small irregularities but is less successful than veneers in the treatment of some problems. The tooth is prepared by etching the surface with a gel.
The surface is then painted with a bonding liquid that sets firmly when a special light is shone on it. A putty like resin is molded onto the tooth and shaped. The light is again used to harden it. The set resin is then trimmed and polished.
Traditional amalgam silver fillings have been successfully used in dental restorations for over 150 years.
There are however, several disadvantages with the placement of an amalgam filling; the most obvious of course is its silver/grey colour, which can detract from your overall smile. It is also possible that the amalgam can cause the tooth to discolour and develop a grey shade.
Amalgam fillings also require a more substantial amount of natural tooth structure to be removed during preparation than a white filling. Unlike white composite fillings, amalgam due to their metal content, are more prone to expand and contract with temperature changes from consuming hot and cold foods and drinks and lead to cracked tooth syndrome.
At Richmond Fine Dentistry we are obsessive about mercury hygiene, when we remove amalgam we use:

Micro-dentistry adopts the philosophy of early detection of tooth decay and minimal treatment procedures so as to preserve as much natural tooth structure as possible, of which micro-air-abrasion plays an integral role.
Micro-air abrasion is a modern technique that uses a fine stream of air-and powder mix to treat mild tooth decay more accurately and with less removal of healthy natural tooth enamel than conventional drilling. It is a gentle, quiet and painless technique that for most cases does not require you to have a local anaesthetic injection.
A tooth prepared using micro-air-abrasion requires a much smaller filling than a drilled tooth, thereby making the final restoration stronger and longer lasting. Once prepared, your tooth is restored using highly durable tooth coloured composite resin making your filled tooth indistinguishable from your natural teeth, so you are able to retain your beautiful, natural looking smile.
Children benefit from the application of micro-air-abrasion. Early detection of tooth decay is especially important in children, as early childhood tooth loss can cause a range of long-term dental health complications. Because micro-air-abrasion is gentle and quiet, children are much more relaxed during their appointment and often unaware of what is being done, as no part of the equipment touches their tooth.
Children’s teeth are also restored using tooth coloured composite resin so they can keep their happy, beautiful smile for many years.
