Metal Fillings Versus White Fillings

Different dentists work differently. Each uses equipment and materials that they believe will achieve the best results for their patients.

However, there are naturally advantages and disadvantages to the types of fillings available and on offer for your teeth. Here we are going to discuss the differences between metal fillings and white fillings.

Metal Fillings (Amalgam)

Metal fillings have been used in dentistry for around 150 years. These filings are made of an inexpensive mixture of Zinc, Tin, Copper, and Mercury.

However, metal filling restorations are very rarely used in today’s modern dental surgery. This is because they look rather unpleasant, and can leak metals into the surrounding tooth structure. This can cause what is called an ‘Amalgam Tattoo’, where the entire tooth can become blackened or gray.

Most people’s concerns are that the mercury in the filling can leak and be absorbed into the system. Indeed this is quite possible, and can cause the patients a wide range of health issues.

In addition, metal fillings do not seal to the tooth structure. They just lie beside the tooth, and thus there is a high risk of bacteria forming under the metal fillings causing tooth decay underneath.

This decay is hard to pick up as it will be under the filling, and not even an x-ray would not show it since it is metal based and would block the image.

Amalgam fillings vontact and expand with heat sometimes causing slight hairline cracks to appear in the tooth.

Therefore it is not recommended for an amalgam filling to be used in any tooth structure.

White Fillings (also known as composite fillings)

White fillings have been used in dentistry for around 25 years.

A white resin material called composite can be used as a restoration. This material is organic polymer mixed with inorganic parts consisting of glass and quartz.

These composite fillings have many advantages. One of the first advantages is that the dentist can remove only the decay in the tooth for this restoration. Other restorations will need larger cavities for strength.

In addition, the look of the tooth is more aesthetically pleasing. This is since there are a wide varied range of materials on the market, allowing the dentist to choose the best one to match the tooth structure.

Composite filling restorations are the first choice for front teeth.  Composites take longer for the dentist compared to amalgam fillings, but the patient is generally very pleased with the results.

There are a lot of cosmetic dentists who spend their days replacing metal fillings for composite fillings.

So contact a cosmetic dentist and replace and repair all the old black cracked metal fillings, in order get a fresh healthy mouth.
