Fillings are used if a tooth has been damaged by decay or is worn or broken. There are different types of fillings available at One Dental Practice.
Amalgam fillings are silver, metal fillings. Amalgam has the benefit of being very strong and long-lasting and the dentist can complete the work in one appointment.They are the least expensive option.
Composite Resin Fillings
Composites are known as white fillings. They are made from plastic and glass particles. The colour of the resin used for the filling is carefully chosen by your dentist so that it matches the tooth it is being placed in, making it a more cosmetic option. Composite resin fillings take slightly longer to complete as they have to be applied in layers which must be cured using a visible blue light. When a layer has cured the next one can be applied until the tooth is restored.
Glass Ionomer Fillings
Glass ionomer is made from acrylic and fluoroaluminosilicate. These fillings are also tooth coloured. They are used for fillings in young children, fillings at the gum margin in adults and for temporary fillings. Glass ionomers also stick to the teeth like composite resin fillings although they are not as strong. They release fluoride which, is the same ingredient in toothpaste used for reducing any further tooth decay.
Root Canal Fillings
Root canal treatment is used when the nerve of a tooth has died or has been damaged and, channels in the roots have become infected. In the middle of the tooth is a soft centre where the nerve lives, called the dental pulp. This goes right down to the end of the root. Bacteria in the pulp cause it to die. The bacteria then spreads along the root channels causing inflammation, which may cause pain and facial swelling, more commonly known as a dental abscess. To treat the infected tooth it may be necessary to perform a dental extraction but it is preferable to save the tooth by cleaning out the root channels and taking away the dead, infected pulp. Once cleaned the root channels are sealed and restored using a filling or a crown.
