Goodbye To The Use Of Mercury In Dental Practices

I think we’ve all seen someone who has a silver coating on their teeth, but what exactly is that silver coating?

That silver dental package is the amalgams; they are used to repair damages present in the teeth, as are mainly cavities. The purpose of this cover is to restore the function that the tooth has lost due to the damage, covering the area affected by the restorative material and thus avoid the presence of future cavities. The problem with amalgams is that, due to the material with which they are made, there have been several cases where people suffer intoxication and is that we remember that mercury (one of the materials with which the amalgams are made) is an extremely toxic metal for humans, causing brain damage and even cancer.

Despite the fact that the treatment of amalgams was very popular due to the resistance of the material and its great usefulness, with scientific advances it has been demonstrated that, as previously mentioned, it can cause damage to health since they are made of 50% mercury, a metal that is toxic to humans and the environment; therefore, many people have chosen to remove amalgams and countries in different parts of the world have preferred to avoid the use of mercury, replacing it with special masks that will fulfill the same function as the previous ones.

There are different fillings that replace the function of the amalgams, among the most popular are:

Resin fillings

Used for veneers, crowns or to repair fractured teeth.


  • Strong and durable
  • They’re tooth-colored.
  • No damage or corroding
  • Prevents health problems
  • Aesthetics
  • Better adaptation to the tooth due to the material

Porcelain / ceramics

The restoration of the tooth by means of porcelain usually covers a larger perimeter of the tooth and simulates the color of the tooth.


  • Good resistance
  • They don’t wear so easily.
  • The material does not cause sensitivity
  • Aesthetic

Replacement of amalgams

If the amalgam is in a deteriorated state, the dentist may choose to replace the damaged amalgam with a restoration of another material. If the amalgam is in good condition and still functional, the dentist will decide, according to his criteria, if they are removed or if they stay better.

Amalgams can be removed depending on:

  • Fractures, leaks or cavities
  • Stains
  • Aesthetics
  • Hydrargyrism

For the extraction of the amalgam it is necessary to have a protocol of security and hygiene, to avoid contamination in the patient and the environment.

  • A separation is used to avoid the passage of contaminated saliva.
  • A sucker is used to evacuate the vapor generated by the mercury.
  • Amalgams are handled at a cold temperature to minimize steam.
  • The patient will receive a special liquid to rinse the mouth before the procedure, this to avoid the absorption of mercury.
  • Both the dentist and the team should use special equipment.
  • It is recommended that this procedure not be performed on pregnant women or those who are breastfeeding.

Indeed, many dentists worldwide prefer to avoid the use of mercury; last year there was a campaign called “Towards Mercury-Free Dentistry”, where different countries joined this cause to eliminate mercury from the health sector. You can consult and research dentists who do not use mercury for their treatments. We recommend you to investigate in the area of Tijuana, due to its proximity to the United States, attend foreign and national persons, look for mercury free dentist Tijuana. Remember to go for options that will not harm your health in the long run and that are friendly to the environment.
