WHY DO I NEED A CROWN
If you want a smile that’s your crowning glory, you may need a crown to cover a tooth and restore it to its normal shape and size. A crown can make your tooth stronger and improve its appearance.
Types of Crown
Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base metal alloys (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably Last the longest in terms of wear down. Also, they rarely chip or break.
The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown’s porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown’s porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.
All-ceramic or all-porcelain dental crown1 provide the best natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal or resin crowns. All ceramic crowns are a good choice for front teeth.
Temporary versus permanent. Temporary crowns can be made in your dentist’s office. Temporary crowns are made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory.

Caring for your crown
To prevent damage to the crown, avoid chewing hard foods, ice or other hard objects, such as pencils. This is especially important for tooth colored crowns. Brush twice a day, floss or use an interdental cleaner once a day to remove plaque. See your dentist regularly for examination and professional cleaning.
How Long does a Crown Last?
The life of a crown is usually 10 to 15 years, different warranties of the crown are available on the basis of your preference.
