Silver restoration or tooth colored restoration?

If you have a preexisting "silver" filling in a tooth or if you have a cavity that needs to be filled, you might be interested in getting some additional information regarding fillings. A traditional "silver" filling is made of an amalgam of various metals: mercury, silver, tin, zinc, and copper. Mercury, which makes up a significant portion of these fillings, is known to have some toxic effect on the human body. Many dentists are now recommending that all such metallic fillings be removed.


This is not a position held by all dentists, but is an issue of which you should be aware. Do your own research on the subject and consult your dentist if you are concerned about any preexisting fillings.

Mercury is scientifically proven neurological poison which affects all nerve tissue including brain. It is also works as an enzyme poison slowing down or preventing these biologically active substances from proper working.

Dental Crown - Do I need one?

If you have a cavity in your tooth, it needs to be fixed as soon as possible to restore the function, integrity and morphology of the missing tooth structure and to prevent complications related to a larger lesion that eventually will become big enough to start causing pain. If the cavity is comparatively small a filling will be a sufficient choice of treatment/restoration. However, if you wait too long and a big part of your tooth is gone your dentist might suggest a crown. You also might need a crown after a root canal treatment since tooth is almost empty inside and very often you have only thin walls surrounding a large defect.



The final decision about the level of restoration that you need can be made only after the comprehensive evaluation of your condition. So don't panic - get a consultation.

There are several different types of crowns that your doctor might recommend to preserve your existing tooth structure and prevent possible tooth fracture.

The most commonly used type of dental crown is the Porcelain-Fused-To-Metal crown which is made out of some kind of metal alloy covered with porcelain. The metal interior provides strength and durability so your restoration can last longer while the porcelain exterior provides a natural and more aesthetically pleasing appearance. Even if it’s not meant to be a crown for a front tooth, some people do not want a metal tooth anywhere in their mouth.

For an anterior (or front) tooth restoration, doctors typically recommend an  All-Ceramic crown –which doesn’t have a metal interior.All-Ceramic crowns are usually used for visible front teeth because crown with metal interiors tend to lose some translucency and in time will appear somewhat darker than the neighboring teeth. The shade and hue of that tooth will always look slightly different from the rest of your teeth. So, to restore a front tooth, you would probably wanta crown that is made entirely of ceramic. A ceramic crown issomewhat more fragile than a crown with a metal core and it is more expensive, but it is much more aesthetically pleasing and the closest thing in appearance to a natural tooth.

Another possibility is an All-Metal crown. You don’t see them much these days for the obvious aesthetic reasons.  Doctors still recommend them in specific situations, basically for patients with pathological bite or a severe parafunctional habit (such as bruxism – when a patient grinds and clenches his teeth causing damage) which might lead to porcelain chipping and crown damage.

Talk to your doctor to see which option is best for you.
