FILLINGS
Most people have fillings of some kind; in the past these have been amalgam (silver coloured) fillings, but most recently most private dentists can offer alternative solutions depending on what is required individually.
White fillings can be used to repair teeth which have been chipped,broken or decayed, and are usually offered to repair "front" teeth as they are the same colour, and come in a range of shades so they can be matched to your original teeth.
CROWNS & BRIDGES
A CROWN (Cap) is an artificial restoration that fits over the remaining part of a tooth, giving it the shape of a natural tooth which may have been broken or weakened by decay.
A BRIDGE is usually used where there are only a few teeth to replace, or when the missing teeth are only on one side of the mouth.
