Differnt types of fillings

Differnt types of fillings

There are a number of different filling materials in use in dentistry.thir are so many types of classifications but we will classify them into :

a.Tooth coloured as

-Composite fillings.

-Glass ionomer

-Porcelain inlays and onlays

b.Non tooth coloured

-Gold inlays and onlays

-Amalgam

Composite fillings

Composite fillings are tooth colored materials and are made from powdered glass quartz, silica or other ceramic particles added to a resin base. Composite has shades in order to match your teeth but over time staining and discoloration can happen.

My advice for people putting composit is to do regular checkups regularly regular every 6 months or whenever they experience any sensitivity or pain.

Glass ionomer fillings

One of the advantages of Glass ionomer fillings is that they form a chemical link with the tooth and also release fluoride, which helps to prevent further tooth decay.

Glass ionomer filling is fairly weak. They can be used on baby teeth and ‘non-biting’ surfaces such as around the ‘necks’ of the teeth. In our surgery we use it as temporary filling material in order to last for longer time than temporary ones.

Porcelain inlays

Porcelain inlays can be made in a laboratory or now in the surgery room using digital technology (called CADCAM) to design and prepare perfectly fitted porcelain inlays. Porcelain can be hard wearing and long lasting. It can also be colored to match your natural tooth.

Gold inlays and onlays

Gold is the most long-lasting ,most ideal , long lasting and hard-wearing filling material .An inlay is small and placed within the biting surface of the tooth. An onlay can cover a larger area of the tooth including cusps.. An advantage of gold is that it does not tarnish and has great strength, but expensive.

Amalgam fillings

Amalgam fillings are silver incolour. Its composed of  silver alloy( 35% silver, and 15% tin, copper and other metals) combined with mercury . Amulgum has been used as a filling material for at least 150 years, its is long lasting and hard wearing It is usual for an amalgam filling to last sometimes up to 15 to 20 years.

Amulgam fillings are usually used on the back teeth what we call molars or grinder teeth, where we need it as chewing compressive strengths can reach up to 30 kilogram.

In regards for the safety use of Amalgam fillings Researches have been carried out for over 100 years. No so far, reputable ‘controlled’ studies have found a connection between amalgam fillings and any medical problem. Mercury in dental amalgam is not poisonous once it is combined with the other materials in the alloy. Its chemical nature changes so that it is harmless
