Tooth Filling

The best way to catch the caries in early stages is regular check ups by your dentist.

In our clinic we do our best to preserve the integrity of your teeth. Careful examination of your teeth will enable us to pinpoint cavities, X-rays will also help locate and see the extent of caries. We will then decide on the best method to restore the integrity of your tooth.  

Not all the caries require filling.

Caries on its initial stage will cause color changes on the enamel, the outermost layer of your teeth. The discoloration might be brown or sometimes opaque white spots. While the caries is on the enamel layer, with an effective oral hygiene measures, the minerals in your saliva may even repair the demineralized spots. We may apply topical fluoride in order to give your teeth extra strength. Fluoride has been shown to form fluoroapatite on the enamel which is even harder than hydroxyapatite (tooth hard structure) itself.  

Once a tiny cavity on the enamel layer forms bacteria finds their niche to grow and attack dentine. The dentine is softer than the enamel. So the caries can sneak inside dentin layer, hidden underneath the enamel. At this stage, hot cold and sweet stimuli may cause sensitivity. In some individuals caries will advance without causing any symptoms. When caries progress, the unsupported enamel will collapse. The food fragments get trapped in the cavity and you may feel the cavity by your tongue. This stage may be too late for simple fillings.  

Treatment of caries in early stages

While the cavity is still small and have not affected the pulp then caries removal and filling will suffice. There are several filling materials available. Previously popular amalgam filling material has gone out of fashion. Today, composite dental fillings are used that is coloured to match the shade of your teeth. So the fillings are practically invisible.
Another material, glass-Ionomer cement is also tooth coloured. It is not as strong as composite but has some decay-preventing ablities. It may be used underneath composite filling and preferrebly used to fill baby teeth. Sometimes short-term (‘temporary’) fillings may be used which then replaced by permanent counterparts.  

After the filling

Following treatment, your tooth may feel sensitivity to pressure, cold air, sweet foods or changes in temperature for a few days to weeks. If your complaints persists, let us know so the cause can be investigated.

 

Treatment of caries in advanced stages

When the cavity is too large there's not enough tooth left to support a filling. The tooth structure may break by chewing forces. In some cases dentin pins are used to enhance the composite resin. Often times, various types of customised restorations called inlay or dental crown made of porcelain may be needed to protect the tooth structure.
