Should a gap between the teeth which is caused by a tooth loss occur, it can be closed by means of a bridge construction. To make a bridge, teeth either side of a gap due to missing teeth are ground and used as so-called bridge pillars; they are used for the attachment of an intermediate tooth. This can be manufactured from veneered tooth-coloured metal or can be all ceramic. Dental bridges can also be worn when implants are present. When gaps occur in healthy teeth, implant prosthetics are considered a sensible and simple alternative, since it means that the neighbouring teeth remain intact.
