Dental restorations

There are many types of filling materials available, each with their own advantages and disadvantages. You and your dentist can discuss the best options for restoring your teeth.

1) Amalgam Fillngs

A silver amalgam filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a silver-coloured filling.
Amalgam fillings, along with composite (tooth coloured) fillings, are still widely used today. An amalgam filling is more commonly used in the back teeth since the colour is not as aesthetic as a composite filling.
As with most dental restorations, amalgam fillings are not permanent and will someday have to be replaced. However, they are very durable and they restore the bite of the tooth.

2) Composite Fillings

A composite (tooth coloured) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc, in the same way an amalgam filling is used.  Because composite fillings are tooth coloured, they can be closely matched to the colour of existing teeth, and are more aesthetically suited for use in front teeth or the more visible areas of the mouth.

As with most dental restorations, composite fillings are not permanent and may someday have to be replaced. However, they are very durable, and will last many years.

3) Porcelain or Metal Inlays

An inlay restoration is a custom made filling made of metal, gold, or tooth-coloured porcelain. Porcelain inlays are popular because they resemble your natural tooth. An  inlay is made by a professional dental laboratory and is permanently cemented into the tooth by your dentist.

Inlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Inlays are an ideal alternative to conventional silver amalgam and composite fillings. Also, they are more conservative than crowns because less tooth structure is removed in the preparation of inlays.

As with most dental restorations, inlays are not always permanent and may someday require replacement. However, they are highly durable and will last many years, giving you a beautiful long lasting smile.

4) Porcelain / Metal Onlays

An onlay restoration is a custom made filling made of metal, gold, or tooth-coloured porcelain. Porcelain onlays are popular because they resemble your natural tooth.

An onlay is sometimes also referred to as a partial or half crown. Onlays are made by a professional dental laboratory and are permanently cemented onto the tooth by your dentist.

Onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Onlays are an ideal alternative to crowns (caps) because less tooth structure is removed in the preparation of onlays. Onlays are essentially identical to inlays with the exception that one or more of the chewing cusps have also been affected and need to be included in the restoration.

As with most dental restorations, onlays are not always permanent and may someday require replacement. However, they are highly durable and will last many years, giving you a beautiful long lasting smile.

5) Porcelain / Metal Crown (CAP)

A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.  Crowns are made to match the shape, size, and colour of your teeth giving you a natural, long-lasting beautiful smile.

Crowns can be made of different materials, and they include:

– All metal crowns.  These can be made of non-precious metal alloys or from gold alloys and they are silver or gold in colour.  Metal is strong and hard-wearing, making these crowns extremely durable especially where chewing forces are high.

-Porcelain bonded to metal crowns.  This is the most common option for a crown.  A metal base is made and tooth-coloured porcelain is applied in layers onto it.  They are a good choice for front and back teeth.

-Full porcelain crowns. Made wholly from porcelain, these are popular because they give a more natural colour match with your natural teeth. They are suitable for front teeth and in some situations, the back teeth.

Crowns are highly durable and will last many years with proper care, but like most dental restorations, they may eventually need to be replaced.

Porcelain Fixed Bridge

A dental bridge is a fixed (non-removable) device and is an excellent way to replace missing teeth.  Typically, a bridge consists of two crowns that are cemented onto two anchoring teeth or implants (such anchors are called abutments), and are attached to pontics (artificial teeth), filling the gap created by one or more missing teeth.

There are several types of bridges. You and your dentist will discuss the best options for your particular case. The “traditional bridge” is the most popular type and is usually made of porcelain bonded to metal resembling your natural teeth. As with most dental restorations, bridges are durable and will last many years with proper care, but may someday require replacement.
