Bonding is a method of restoring tooth surfaces as well as covering discolourations, cavities and deformations with composite resin - the material is available in various colours which can be matched to the colour of the dentin and the tooth. In this way, dental crowns can be given a smooth and aesthetic appearance. When carrying out the bonding procedure, the dentist must have the necessary manual skills - the appearance of the restored tooth will depend on his/her dexterity.
