An allergy is an inflammation or disorder that occurs when the body comes into contact with or accumulates a substance (allergen) that is the source of the allergy.

Allergens in metal allergies due to silver teeth are,Metal ions dissolved in the mouth by salivaIt is.

Metals have the property of becoming metal ions when exposed to moisture. Simply put, it is like silver teeth that come into contact with saliva gradually dissolving.

The metal ions of silver teeth dissolved in the mouth,It accumulates in the body over a long period of time through direct contact with the mucous membranes of the mouth or when swallowed with saliva, causing allergic reactions.

Metal allergies develop slowly, so it is unlikely that you will develop an allergy immediately after having silver teeth.

Most often, symptoms such as inflammation of the mucous membranes of the mouth and eczema of the hands and feet appear about five years after the silver teeth are placed.

Symptoms of metal allergy caused by silver teeth

Symptoms of metal allergy caused by silver teeth include

• It occurs where the silver teeth are in direct contact with the "Contact metal allergy"
  • stomatitis
  • glossitis
  • glossophagia
  • lichen planus
  • Taste disorder, etc.

• caused outside of the mouth by metal ions accumulated in the body.Systemic metal allergy"
