Symptoms of metal allergy

Dental materials (particularly metals) cause mainly allergies on the oral mucosa or on the skin.
Local reactions in the mouth cavity: burning mouth, tingling tongue, dry mouth, ulcers, redness, gingivitis, inflammation  of oral mucosa, tongue, lip; pathologic hornification, leukoplakia.
Remote skin reactions: burning, itching, redness, blisters, eczema, dermatitis, hair fall.

Metal allergy test:

The above listed dental metals and acrylic allergens are used to test the most common contact allergens. Epicutan (patch) test is most suitable for testing allergies to dental materials
Tiny quantities of allergens are applied to the upper back; they are kept in place with hypoallergenic adhesive tape. Results will be interpreted from the reactions of the test sites.

Dental metals: Nickel, Chrome, Cobalt, Silver, Gold, Amalgam, Mercury, Zirconium, etc.

Acrylic allergens: Acrylates, UV absorbents, fragrances, composite dental resins, preservative agents

According to skin tests, 35-40% of tested patients have allergic reaction to some dental material; 15% men, 85% women.  2/3 of them is allergic to one, 1/3 of them is allergic to more materials. Metals triggered most of the positive allergic reactions.

How metal allergy can be managed?

The only and most efficient way is to avoid the allergen metal. Once a metal allergy has been developed, it will remain for the rest of life. Unfortunately, actually there is no procedure to heal metal allergy. In many cases, avoiding the metal means: don’t wear some jewels, refrain from some cosmetics, have dental fillings, replacements, implants changed.
