After getting top and bottom partial dentures in August 2023, I developed sores in my mouth and on my tongue. My dentist referred me to multiple specialists before I decided to get allergic testing. I am allergic to nickel and have a list of other metal allergens. Could the allergic reaction make me feel physically sick? I feel better when I remove the partials after getting home from work, but worse during the day. Thanks. Kelli from Montgomery, AL

Kelli,

Since you experienced some relief at night when removing the partials, it’s clear your body was reacting to exposure to the allergenic metals.

Metal Allergies and Removable Partial Dentures

The number of cases where people tell us their dentist is unaware of metal allergies is alarming. Allergies and sensitivities are fundamental and essential aspects of dentistry. Yes, you can become physically sick from constant exposure to metals you are allergic to. Your sickness may be related to your metal allergies and the recent placement of removable partial dentures.

Case Study: Allergic Reaction to Mercury Fillings

One dentist had a rare case of a woman with a confirmed allergy to mercury. Due to her allergy, the dentist removed all the patient’s amalgam fillings, replacing them with composites. After the first appointment, she developed a rash and breathing difficulties due to exposure to amalgam dust. The dentist took precautions to avoid further exposure during subsequent appointments. After replacing her amalgam fillings with composites, the patient reported that her arthritis had disappeared. Her dentist was confident that her arthritis was related to her constant exposure to the metal allergen.

Nickel Allergies and Removable Partial Dentures

Consider a few facts about nickel allergies and removable partial dentures:

• Many removable partial dentures are made from a nickel-free alloy called Vitallium.
• Some less expensive alloys contain nickel or other metals that can cause reactions.
• Around 10% of women and 1% of men test positive for nickel allergies. “Are you allergic or sensitive to any metals?” should be a standard question on every dentist’s medical history form, particularly if they use non-precious metals in their restorations.

Dentists should inquire about metal sensitivities before treatment. A growing number of dentists exclusively provide mercury-free and metal-free restorations, eliminating the need to ask about metal allergies. Others are willing to provide alternatives to restorations that contain metal or mercury.

You can consult a cosmetic dentist willing to use metal-free materials for a partial denture.
