My 13 yr old DS needs a filling on one of his permanent back molars. Our insurance does not cover a porcelain crown, which my dentist is recommending. Is it not a tooth that is visable, so we are debating the need for this and are seriously considering going with a regular silver resin filling...any opinions out there???
I'm a dental hygienist. Your post is a bit confusing since you say he needs s filling but the dentist is recommending a crown. Also, the tooth colored filling material is composite resin, and silver fillings are amalgam which basically means it's an amalgamation of different types of metals.
We don't typically do porcelain crowns for 13 year olds. We would do a silver temporary crown until he was 16-18 in an effort to make sure the entire tooth is fully erupted, then do a permanent crown later so the margin (edge next to the gumline) of the crown would be healthy for the tooth and gum. Also, if orthodontia is involved, we typically like to wait until the teeth are moved and then do the permanent crown. It's possible the dentist thinks your son's tooth is fully erupted and ready for permanent crown placement. In a case like that, I'd advise you to think about how much you'll be able to see the crown when he speaks and laughs. Sometimes we have no choice about the type of crown and have to do a silver one. You seem to have a choice on the aesthetics. They are both strong and have a history of lasting the same length of time.
If we are talking about a filling, which I kind of doubt since you say it will cost $683, then while amalgam fillings can be stronger, they also do not ADHERE to the tooth like a composite resin filling does. Amalgam stays in place by removing more of the natural tooth surface doing undercuts and wedging the material in. Porcelain actually bonds to the natural tooth surface and holds it all together. Research shows that amalgam tends to have a longer life span, an average of 10 years, while composite is an average of 8. However depending on the size of the amalgam, it can be more likely to fracture or crack the tooth by pushing it apart since it acts like a wedge.
As a parent and a professional, I would recommend a composite, if we are indeed talking about a filling, however as I said, I think you are probably talking about a crown due to the expense you listed.
