Amalgam vs Composite

In order to choose the treatment that is best for you, it is important to know the difference between the two. Continue reading for more information about amalgam and composite fillings in San Jose.

What are Amalgam Fillings?

Commonly known as “silver” fillings, amalgam has been in use for over 150 years. It is a mixture of metals that is firmly compacted into the tooth in order to restore the tooth structure and fill the site of decay.

In order to place amalgam fillings, the dentist will first ensure that all signs of decay are removed from the tooth. They will then take a capsule of powdered alloy and mix it with liquid mercury to form the pliable, putty-like amalgam material. The amalgam material is then packed into the tooth, where it quickly hardens. The dentist will then file off any spots that are too high for the patient’s bite and the appointment is concluded.

Amalgam fillings are extremely strong and durable and have been known to last patients their entire lifetime, making them extremely dependable. They are also the cheaper option when compared with composite fillings.

While amalgam fillings can be very beneficial, there are some negative aspects to consider, as well:

• Many people do not like the look of amalgams, as they are easily detectable and look like “metal”.
• Amalgams are a mixture of mercury, lead, copper, and nickel. Mercury and lead have proven to be toxic.
• Amalgam fillings require a deeper and wider space to be drilled out prior to filling. This may eventually lead to further damage should the filling crack, break, or fail.
• Metals expand with extreme hot or cold; this could lead to the fracture of the tooth in some cases, which could lead to the need for a root canal.

Due to the reasons listed above, dentists usually strongly prefer the use of composite fillings for their patients.

What are Composite Fillings?

Also known as “white” fillings, composite fillings are comprised of a durable resin material that is matched to the shade of the patients’ teeth.

To place composite fillings, the dentist will remove all decay in the tooth. They will then need to ensure that the area is completely dry during the entire time that they will be working, as composite fillings will not correctly bond to the tooth if they become wet. The dentist will carefully work to apply a bonding solution to the tooth and then place the composite material inside the tooth. The material remains in a putty-like form until it is cured by a UV light. It is then that it hardens and can then be smoothed and filed as needed.

Composite fillings have become wildly popular in modern dentistry, mostly due to the fact that they are nearly impossible to see without the help of an x-ray. The biggest drawback of composite fillings is that they are not as durable as amalgam fillings, and in most cases must be replaced after some time has passed. They are more expensive than amalgam fillings, so for those who are on a budget, composite fillings may not be the best option.

After you have a filling placed, whether it be composite or amalgam, it is common to experience some sensitivity. Your dentist will instruct you on how to best care for your tooth post-op and will most likely suggest that you refrain from foods that are hard, sticky, or extremely hot or cold.
