hi! this is dr. alida smisek on behalf ofexpertvillage.com. i'm here to talk to you about teeth whitening tips and techniques.in this clip, we're going to talk about how to whiten teeth with crowns or veneers. unfortunately,some teeth that are heavily restored, may have had root canals, or are severely discoloredare very difficult to whiten with the products that are available on the market. in caseslike this it can be very challenging to get a good cosmetic result and you may have toconsider some other procedure such as crowns or veneers. a veneer is basically a littleporcelain fingernail, if you can visualize that, that gets applied to the front surfaceof the tooth. it's a nice procedure because it doesn't require a lot of tooth reduction,and it actually is bonded to the enamel of
your tooth. one of the things that you haveto be careful with veneers is because the porcelain is so thin it can fracture easilyso you have to kind of treat them a bit of tlc. another procedure that can be used isa crown. a crown is a little more invasive in the fact that we have to remove more toothstructure. basically, your dentist would do a preparation on your tooth. this is justa model that someone who has had a crown made. reducing all around the perimeter of the tooth,and then a lab would make a porcelain type of crown that can get cemented right overthe top of your tooth. because this is all the way around the tooth, it provides morecoverage and it is actually an ideal solution for a tooth that has been heavily restoredor has had a root canal. as you can see, it
can be made of all porcelain, which can bevery aesthetic and it can be matched to your natural teeth on either side of the crown-coveredtooth.
