A - Often times this is due to the shadow created by the metal at the margin of a porcelain crown. The metal is often used for strength and reinforcement for the overlying porcelain. There is a way around this problem. Your dentist can instruct the lab fabricate eithern an all porcelain crown or a metal and porcelain crown with an ALL porcelain edge (margin) to create a more natural cosmetic appearance. At our office, it is very rare for us to make crowns with metal margins. See similar questions...

The black line is often caused by a poorly fitting crown with recurrent decay. Metal-ceramic restorations can result in a shadow being created by the metal core stopping the light from transmitting down the root. This can produce a black line as well as a greyness of the surrounding tissues from lack of light transmission. It can also be caused by a reaction to the tissue called tattooing.

Crowns that show a dark area at the gum line reflect an inner metal layer that is covered over with porcelain. With all-ceramic crowns, teeth can be made to look completely natural, even at the gum line area. See similar questions...

It is a black optical coating beneath the highly reflective aluminium coated surface. This black coating absorbs the internal reflections within the projector that can lead to a halo or glow around the projected image. See similar questions...

This is caused by the underlying metal lining of the crown which makes the tooth look artificial and fake. Contemporary cosmetic dentistry affords us to completely avoid this unsightly problem. When it is absolutely unavoidable to use crowns we prefer to use all porcelain crowns. The strength of this crown is similar to the metal lined porcelain crowns and some even suppress that. All porcelain crowns allow light to pass through just like the enamel on teeth does. See similar questions...

The margin where the crown meets the tooth should have no ledge. If not trimmed back and made smooth, harmful bacteria are harboured here, if not kept clean. Bacteria can lead to decay and periodontal disease, so correct brushing at the gum line with daily flossing as described by the dental hygienist in your dental practice is important. Regular checkups are essential to identify any problems as early as possible to avoid expensive treatments later. Two months ago I had three crowns fitted. See similar questions...

Preparing and placing a crown will require two visits with Dr. Wooten. During the first, Dr. Wooten will prepare the tooth for the crown placement, find your perfect shade, and fit a temporary crown. After one to three weeks, you will return for the permanent placement of the crown. See similar questions...

Dr. Wooten's crowns have proven to last a very long time, sometimes over two decades. With proper home care and routine check ups, your dental crown can maintain its form and function for a very long time. See similar questions...

People who have anorexia often have saliva that is deficient in the buffers that protect teeth from the effects of acid manufactured by bacteria in the mouth. There is also significant acid in many of the low-cal foods and soft drinks that anorexics favor. Normal saliva contains buffers that protect teeth from acid. The body makes those buffers in part from materials found in fatty foods. If you don't eat enough dietary fat, your body can't protect your teeth adequately. See similar questions...

The black spots on teak are commonly mistaken for dirt getting stuck in the wood. However, the black spots on teak are actually mould and mildew which are growing in the wood and teak oil which was baked by the sun. Golden Teak Cleaner will remove any mould and mildew that may have accumulated. However, if teak-oil is used again the problem is likely to reoccur as the mould and mildew will have food again! Teak becomes gray because of Ultra-Violet rays from the sun. See similar questions...

This can occur for several reasons: the crown may not fit well, it may be too far under the gum, or it may have a metal base that blocks light. Teeth are like little fiber optic units. When light hits them, it illuminates the teeth and the surrounding gum tissue to give it that healthy pink glow. Metal blocks the light, causing the tissue to look dark. Non-metallic crowns are best for a natural appearance. See similar questions...

These are restorations to repair a severely broken tooth by covering all or most of the tooth after removing old fillings, fractured tooth structure, and all of the decay. The restoration material is generally made of gold or porcelain. Dentists refer to these restorations as "crowns". However, patients often refer to the tooth-colored ones as "caps" and the gold ones as "crowns". See similar questions...

According to Mr L.H. Ladner whose family has owned these dogs for several generations, the Black Mouth Cur was called a black mouth due to the black lips around the mouth. The lips are black because they have no fur to hide the intense pigmentation of the skin. The dark coloring continues into the mouth pigmenting the inside fleshy mouth parts with the exception of the tongue. It is thought by some that the dark skin helps prevent sunburn.

A.: Sheetfed process black inks are made to print as part of a process set. The tack is normally quite high, as most process printing is done with dark-to-light color sequence on multi-color sheetfed presses. A fourth-down black is also made for certain jobs where it must overprint an opaque or metallic color. The color is also balanced to the requirements for process work; not too blue nor too yellow.

A#4.6: There are two. The first is "-c arg", which is supposed to allow one to specify a script on the command line. This seems to be broken, though. The second one is "-f", which tells gsh not to parse its gshrc file, nor do other initialization tasks. Think of it as "fast startup". Unfortunately, empirical tests seem to indicate that gsh is no faster with this flag than without. See similar questions...

Gum disease begins when plaque adheres at and below the visible edge of your gums. If plaque is not removed every day by brushing and flossing, it hardens into tartar. Tartar promotes a bacterial infection at the point of attachment. In these early stages, gum disease is called gingivitis. Your gums may be a bit red but you may not notice anything. As gingivitis gets more serious, tiny pockets of infection form. Your gums may be puffy and may bleed a little when you brush but it is not painful. See similar questions...
