Restorative Fillings

Restorative Fillings

What are restorative fillings?

Fillings are needed if you have tooth  decay or a broken tooth. If the filling is very large then sometimes crowns or inlays / onlays maybe needed to protect the tooth further. There are three main types of fillings , amalagam metal fillings, composite white fillings and glass ionomer fillings in certain situations. 

Composite Fillings

These are tooth-coloured aesthetic fillings.

The main advantages are:

Superior aesthetics 

Composite fillings can be made to look smooth and glassy, which gives a natural-looking surface ideal for matching the appearance of front teeth. To give an even more natural appearance, various stains can be added to match existing teeth precisely.

Bonding

Composite material can be bonded to the tooth substance. which helps to strengthen and support the remaining tooth structure as well as keeping the filling in place better that other types of filling.

Strength

Composite fillings are made from a mixture of different components. The proportions and even the materials used can vary depending on the exact requirements of the filling. For example, for back teeth, fillings need to be strong to withstand chewing, but for front teeth the appearance of the filling is more important.

Glass lonomer Fillings

Glass Ionomer is a polymer made from organic acid and modified glass particles. Fillings made of this material are mainly used near the gums. They are often used for filling children's teeth.

The main advantages are:

Adhesion

Glass Ionomer is naturally adhesive to tooth substance, which prevents leakage and minimises disruption to the seal of the filling, preventing bacteria getting inside the tooth.

Fluoride

These fillings release fluoride over time, helping to strengthen and harden the enamel adjacent to the filling. This has the effect of preventing further decay around the filling.

Tooth-coloured

Glass Ionomer fillings are available in different shades to match the colour of the existing tooth.


Metal Amalgam Fillings

This is one of the longest-standing materials used in dentistry. Its contents are 40%-50% mercury, and the rest is alloy powder consisting of silver, tin and copper. More modern materials are slowly taking over from amalgam, but there are still some cases where we need to use it.

Silver Vs White Cosmetic Fillings

Bonded Ceramic Onlay

For larger cavities, or replacing large fillings, we recommend bonded ceramic restorations, such as ceramic onlays or crowns

The main advantages are:

Strength

Modern-day crowns or onlays made with zirconia and pressed ceramics has improved strength as well as a natural appearance. This allows us to use ceramics in situations where there is increased bite pressure.

Accurate fit

As these are individually hand-made by a ceramic technician or digitally milled in the dental laboratory using measurements of the tooth, they are specifically made to fit precisely for that tooth.

Superior aesthetics

The ceramic restoration can be made using a layered technique which allows different parts of the restoration to have their own colour and translucency to match the surrounding tooth material.

Bonding

As the ceramic can be bonded to the tooth substance, it will provide an accurate and stable fit, seal and support to the tooth structure.
