Question:
Crowns - Bonding Material:
My father had new crowns put in his mouth, as well as bonding on his front teeth, both upper and lower. For the past couple of months, since the dental work, he has had problems with taste - the foods do not taste as they should, as well as waking up with a film in his mouth.
Could these be allergic reactions to the make-up of the crown and/or the bonding material? ...Visitor from FL
Answer:
People do have allergies to certain dental materials, in particular metal allergies. Metals such as nickel can cause an allergic reaction. Nickel can be found in the stainless steel posts that are used by dentists. Nickel-chromium alloy is what makes it stainnless steel.
I have gotten away from those types of posts and use either a surgical grade titanium or a fiber posts. Nickel can also be found in some of the lower grade metals used for porcelain crowns.
Generally, more women are allergic to metals than men. People who are allergic to metals usually can tell by the jewelry they wear. I would first eliminate the possibiity of a nickel allergy and then look for other reasons.
Perhaps there could be an electrolytic reaction going on. If a high noble metal such as gold is placed over an amalgam or near a new amalgam it can generate an electrolytic response.
Look at these possibilities first.
