The area can get a bacterial infection that leads to pus cavities forming in the gums; symptoms include severe headaches and toothaches,the infection can travel to the brain and be fatal.
Fillings are made of different materials so your dentist will choose whichever one he feels is best for you based on how big your cavity is and where it is located. They will also consider the cost – some fillings are more expensive than others.
Different materials that are used to make fillings and restorations come with both advantages and disadvantages.

Composite resin The filling can be direct – the dentist used a special blue light to bond it to the tooth right away, or it can be indirect where the dentist takes a mold of the tooth, sends it to a dental lab for them to create the filling and then insert it into place using a special kind of bonding agent.
Gold Alloy A gold alloy filling is the strongest filling of them all. These kinds of fillings are made from a mix of gold and several other metals. It looks much better than a composite resin filling which is silver.
Advantages of Tooth-Colored Restorations?
There are many advantages to tooth-colored restorations. Resin Onlays are bonded to the teeth creating a tight, superior fit to the natural tooth. Such restorations can be used in instances where much of the tooth structure has been lost. The tooth remains intact and stronger.
Since the resin used in tooth-colored restorations contain fluoride this can help prevent decay. The resin wears like natural teeth and does not require placement at the gum line, which is healthier for your gums!
