Dental Metal Activity Meter

The Dental Metal Activity Meter is used to measure galvanic current. Galvanic current is a term that has been used in dentistry for over 100 years. It is a condition created by the presence of dissimilar metals in the oral cavity of the teeth and gums, with saliva serving as the electrolyte.

What does galvanic current?

Have you ever felt a “shock” to your teeth caused by a piece of tin foil or a spoon that touches a sliver or mercury filling in your mouth? If you answer yes to this question, you’ve experienced a galvanic event.

Galvanism can cause a metallic or salty taste in the mouth, increase salivary secretion, and burning or tingling sensation of the tongue. Other systemic complications may include headaches, chronic fatigue, memory loss, sleep deprivation and even irritability due to its effects to the central nervous system.

Measurement with Dental Metal Activity Meter

The Dental Metal Activity Meter can be used to measure electrical charges on fillings, crowns and metallic appliances. Metals will not necessarily always cause the galvanic effect in the mouth. It depends on the specific metal and alloy being used along with quantity and placement in the mouth. However, knowing that some of the above symptoms could be dental related may provide you with an opportunity to evaluate your mouth from a different perspective and discover once and for all if there is a galvanic current present in one or multiple sites in your mouth.
