Dental Health and Tooth Fillings

Dental Health and Tooth Fillings

Dental Health is one of the important factors which one should not ignore. In dental health, cavity is one of the most common problem which one faces. Decay happens over a period of time and the result is a cavity. Teeth are covered by a hard material called enamel, which gets eroded by acids produced by bacteria, this in turn leads to the cavity. A filling helps to restore a tooth damaged by decay back to its normal shape and function, and helps prevent future decay by removing areas where bacteria can enter the tooth.

There are various types of fillings available:

Amalgam Fillings – Amalgam fillings which are made from a mixture of metals including mercury and silver, is usually used for fillings in the back teeth. These fillings are very strong and last for a longer time.

Gold Fillings – Gold fillings are made from gold and are durable. They do not match the colour of the teeth and are usually expensive.

Composite Fillings/ White fillings – These are BPA free fillings and are mostly used for kids. They are also known as white fillings because they match the colour of the teeth. White fillings are composite resin fillings, which means they are made from a combination of elements, which includes glass and plastic. They’re designed to both hide the cavity and protect the teeth.

Glass Ionomer – These fillings are made from acrylic and Fluor aluminosilicate, which is a component of glass. This type of filling is quite durable and mostly used in people with a lot of decay in the part of the tooth that extends below the gum.

Ceramic Fillings – They are more brittle and can break but they are also more resistant to staining. They are made of porcelain and are same colour as the teeth, so they look natural. They are quite expensive and can cost more than gold fillings also.

What Steps Are Involved in Filling a Tooth?

First the dentist uses anaesthetic to numb the area around the tooth to be filled. Next, a drill, laser or abrasion instrument is used to remove the decayed area. Once the decay has been removed, space is prepared for the filling by cleaning the cavity of bacteria and debris. If the decay is near the root, dentist may first put in a liner made of composite resin, or other material to protect the nerve.
