After Dental Crowns

If you need more involved treatment that still
looks natural, your dentist may recommend a crown, inlay or onlay. A
crown covers the entire tooth to strengthen and improve its appearance
and is typically used when a tooth's damage is beyond the scope of more
conservative esthetic procedures mentioned earlier. However, if enough
healthy tooth structure remains, your dentist may conserve what's left
and restore the tooth to a natural appearance with an inlay, which fits
within the contours of a tooth, or an onlay, which is similar but also
covers some of the chewing surface of a tooth.
Crowns, inlays and onlays are typically fabricated
from an alloy, a combination of metals. Alloys may contain precious
metals such as gold and palladium, or non-precious metals such as nickel
or chromium. In either case, they are incredibly durable, with many
crowns lasting 20 years or more.
Crowns can also be made entirely of porcelain,
or with a metal lining to which an outer layer of porcelain is fused.
Crowns made entirely of ceramic also are available today, but questions
remain about their durability and strength when subjected to the intense
chewing pressures generated when we eat. The best advice is to consult
your dentist if you are interested in a ceramic restoration,
particularly for back teeth.
