What Are They?
A filling is a specialised material designed to be compatible with teeth and which is placed into a tooth to fill a void or hole caused by decay or fracture.
What Is Important To Know About Dental Fillings?
- There are two main types of materials used in dental fillings: dental amalgam and composite resin.Each material has advantages and disadvantages;
- It can sometimes be difficult for an individual to know if they need a filling, because most small to moderate-sized cavities (areas of tooth decay) do not cause any pain or discomfort; &
- Decay is usually diagnosed by a dentist using inspection or xrays. Some cavities are too big for a filling and need to be fixed with
something larger and stronger.
More Detailed Information About Dental Fillings
How a Filling Is Done:
- Most fillings are placed only once the tooth has been anaesthetised (numbed);
- If the void in the tooth was caused by decay, the decay is removed;
- Any weak tooth enamel is also removed;
- The cavity is washed thoroughly and dried before the filling is placed;
- If composite resin is used, the cavity is first treated with some liquids which allow the composite resin to bond to the tooth;
- The filling material is packed carefully, often in stages, to prevent voids being left behind;
- Composite resin fillings are hardened via blue light activation;
- Dental amalgam and some other filling materials harden by chemical reaction;
- The filling is shaped to match the curvature of the tooth and to fit into the bite;&
- Some fillings require polishing by the dentist to achieve a smooth, easyto-keep-clean surface.
How Long Do Fillings Last?
- It depends on the many factors, the main ones being the size and location of the filling and what stresses it endures;
- A small filling in the groove on the side of a tooth endures no pressure and can last decades;
- A large filling covering the chewing surface of a molar of a person who grinds their teeth every night may last less than a year;&
- An individual’s dental hygiene, dental habits (like chewing fingernails or pens), diet and lifestyle will also have an influence on the lifetime of a filling.
Can All Teeth Be Successfully Filled?
- Unfortunately no. Some cavities are too large to be successfully filled using composite resin or dental amalgam;&
- When fillings are unlikely to be successful, your dentist will offer options that may include stronger porcelain or gold restorations, including dental crowns, inlays or inlays.
