Stainless Steel Crowns
IN KEENE, NH
Crowns, or caps as some people refer to them, are a protective shell-like covering cemented to the tooth. Dental crowns protect and strengthen a tooth that may have been compromised by:
- Removal of a large amount of decay
- Abnormal formation of the tooth itself
- Therapeutic pulpotomy or pulpectomy (pediatric root canal)
- Extreme sensitivity
Crowns are made to mirror the shape and size of the natural tooth and will completely cover all surfaces down to the gumline. By protecting the primary tooth, it can remain in place and guide the incoming permanent tooth.
WHY DO YOU USE STAINLESS STEEL?
Crowns can be made from a variety of materials however for over sixty years, stainless steel has been the preferred material used in pediatric dentistry, especially for molars (back teeth) which is where they are most often needed. Occasionally, stainless steel crowns are placed on permanent molars however other materials are usually used for adult teeth for cosmetic reasons.
Stainless steel is extremely durable making it a great choice for children. But perhaps the greatest reason for using stainless steel crowns in pediatric dentistry is that the material allows them to be pre-formed. Having a pre-formed shell eliminates the need for impressions which can be a difficult process for a child. Dr. Norris is able to choose the crown that best matches the natural tooth. He can then adjust the pre-formed crown to the size, shape, and anatomy of the natural tooth prior to permanently placing the crown in the mouth. Minimal adjustments are needed in the mouth which makes for a much shorter procedure. An easier and shorter treatment time means less stress for the child and parent.
DO STAINLESS STEEL CROWNS HAVE MERCURY?
It is widespread knowledge that the dental fillings of yesteryear (amalgam) contained mercury however stainless steel crowns do not. Stainless steel is a composite of nickel, iron, and chromium making them completely non-toxic.
