Metal Allergy
When you have metal dental work in your mouth, one
possibility is that you can have an allergy to that metal.
This will cause chronic inflammation around that dental work.
Many people are allergic to nickel. Often the
allergy becomes noticeable with earrings and people will need to get
non-allergenic earrings, made without nickel.
Nickel is a component of some alloys used for
dental crowns and
removable partial
dentures. If you have a sensitivity to nickel, you will experience a
chronic inflammation around these crowns or partials.
Nickel is also present in some
dental posts or
dental pins that are
used in teeth with root canal treatments, to help strengthen the tooth and
retain a dental crown. Most metal posts these days are made out of
titanium, which is a very bio-compatible element, but posts with nickel in
them are still available. Some may argue that a post inside a tooth will
not provoke any allergic reaction, but the tooth root is porous, and
molecules of corrosion products of metals inside the tooth can easily seep
through the tooth, given enough time.
Allergy to dental amalgam, an alloy of silver,
mercury, and small amounts of tin, copper, and/or zinc, is very rare, but
instances have been reported. We are not aware of any documented allergies
to precious metals such as gold and platinum.
