Failing Amalgam

Amid the present controversy, there are Dental and Health issues you should be aware of!

At my dental clinic in Portland, Oregon, I see many mercury fillings every day that have been placed anywhere from a few months to thirty or more years ago. Most patients assume that once placed these mercury fillings last a lifetime.

In my clinical experience I find with older mercury fillings (greater than 10 years):

  • Internal cracks that if left to propagate would result in either root canal treatment or a fractured cusp (needing a crown) or both.
  • Most of these teeth contain significant levels of decay.

Bravo Smile is proud to be a mercury-free dental practice.

This image below is a tooth that had a FAILING AMALGAM. It had to be prepared for a full crown. Decay, shown as the dark area, still needs to be removed. The decay is very close to the pulp and the tooth ultimately required root canal treatment.

The images below show two FAILING AMALGAMS with gaps and corrosion around the margins.

 

A tooth with a failing amalgam: It had to be prepared for a full crown. Decay, shown as the dark area, still needs to be removed. The decay is very close to the pulp and the tooth ultimately required root canal treatment. A tooth with a failing amalgam: The tooth to the left had lesser marginal gaps, however, the decay under this FAILING AMALGAM had to be restored with a root canal treatment and a crown.

The two images above represent old mercury fillings. The tooth on the left has a crack through the middle of the filling. After the filling was removed there was decay into the pulp. Chips and fractures of the filling can be noted next to this large crack. Where did this large chunk of mercury filling go?

The tooth to the right had lesser marginal gaps, however, the decay under this FAILING AMALGAM had to be restored with a root canal treatment and a crown.

These teeth were originally restored while the patient was a teenager. They did not hurt before the mercury filling was removed. The patient had regular care for the last twenty years and no comment was made about possible problems.

Decayed tooth structure is essentially dead tooth material and is a great insulator. That is why patients with very deep decay under these old fillings will often report no sensitivity or pain.

I call these fillings THE FAILING AMALGAM. They contribute significantly to the number of crowns and root canals that are being done in the U.S. Mercury fillings corrode and leak over time! That is one of the main reasons why our dental practice in Portland, Oregon is completely mercury-free.
