Welcome to JustAnswer, and thank you for putting your trust in me!
There are several issues implicit in your question.
First-- regardless of whether there were prior extractions for orthodontic reasons, it is not generally customary to expend extraordinary resources on the structural restoration
of wisdom teeth
. In fact, this is especially the case when orthodontic treatment is performed, because there is a general consensus that wisdom teeth can contribute to tooth crowding, which can jeopardize the orthodontic result. Additionally, the wisdom teeth are often situated in such a way that they contribute little or nothing to the functionality of the mouth, and they often lead to gum inflammation
and overt infection
. Some dentists automatically recommend the extraction of all wisdom teeth as a matter of course, in order to avert any of these problems
commonly associated with wisdom teeth. In unusual cases, wisdom teeth may merit the effort and expense of restoration-- for example, when adjacent teeth are missing and they are needed to support either a fixed or removable dental
prosthesis, but in most cases, placement of crowns on wisdom teeth is unwarranted. Granted, whatever benefits you could have expected from placement of a crown on your wisdom tooth would have been a subject to discuss with your dentist before
you implemented treatment.
However, in principle, I am inclined to agree with your dentist as regards XXXXX XXXXX of a metal crown over a porcelain crown. This is not only due to the inherent fragility of porcelain, which is potentially problematic in a high-stress application such as this, but also because wisdom teeth are typically short, and cannot be drilled down sufficiently to create enough space for porcelain over the chewing surface of a crown without severely compromising the strength of the bond between the crown and the tooth. Each case must be considered on its unique individual circumstances, but the placement of a porcelain crown in wisdom tooth position runs the risk of compromising functionality for the dubious advantage of a nice looking crown in a position that is not visible.
As regards XXXXX XXXXX taste: unless that new crown is in direct contact with other metal in your mouth-- perhaps another metal crown or a metal filling in an adjacent or opposing tooth-- most dental casting alloys would not taste metallic, and it is likely that the taste is coming from something else. That something else might be some uncured resin cement
, or it might even be due to residual gum inflammation from the crown procedure itself. I would recommend that you wait at least two weeks to see if the taste resolves on its own before you return to your dentist for further assessment.
As for the "slick feel" of the crown-- this is not related to its metallic composition, but rather because it is smoother than what was there before (presumably, either a broken tooth
or an acrylic temporary crown). Hypothetically, had your crown been made of porcelain, it would have been even "slicker"-- glazed porcelain has a smoother surface than polished metal. Within a day or two, you will become accustomed to your new crown.
Hope this helps...
