To restore Decay tooth

A cavity or tooth decay occurs when the enamel or dentin de-mineralised and infected with bacteria. The infected and de-mineralised part of the tooth/teeth is removed and the space is restored with filling material.

Types of Restoration

  • Amalgam Restorations

  • Composite Restorations

  • Glass Ionomer Restorations

  • Indirect Restorations

Amalgam Restorations

Dental amalgam is the most researched and tested restorative material among all in use.

Positives of Amalgam Restorations :

  • It is durable.

  • Easy to use.

  • Highly resistant to wear and tear.

  • Can withstand very high chewing loads.

Disadvantages of Amalgam Restorations :

  • There could be some short-term sensitivity to heat or cold after the filling is done.

  • It is silver coloured and does not look natural.

  • The dentist may need to remove more tooth structure to accommodate an amalgam filling
    when compared to other types.

Composite Restorations

  • Composite fillings are durable and are fracture-resistant.

  • Recommended in small and mid-size restorations in teeth that handle moderate chewing pressure.

  • Less tooth structure is removed during preparation, resulting in a smaller filling than that of an amalgam.

  • Composites can also be "bonded" or adhesively held in a cavity, which allows the dentist to
    make a more conservative repair to the tooth.

Glass Ionomer Restorations

  • Glass ionomers are translucent, tooth-coloured material which are primarily used in teeth
    that are not subject to heavy chewing pressure, as they have a low resistance to fracture.

  • They are mainly used in small non-load bearing fillings or on the roots of teeth.

  • Glass ionomers release a small amount of fluoride, which is beneficial to patients at risk of decay.

Indirect Restorations

  • Sometimes the best dental treatment for a tooth is a restoration made in a lab from a mould.

  • These custom-made restorations require two or more visits.

  • Materials used to fabricate these restorations are metal and ceramic.

  • The strength of this type of restoration depends on an adequate thickness of ceramic
    and the ability to be bonded to the underlying tooth.

  • They are highly resistant to wear and tear.
