When you have a dental crown, it is less common to have a cavity on the tooth because it is protected. However, the place where the crown meets the tooth can still get a cavity, that is why hygiene is important even though a crown is on the tooth, especially flossing. The two ways to get a cavity under a crown are:A cavity started between the crown and the tooth at the gum level.There was a cavity left on the tooth when the crown was put (more rare).
Poor filling on a root canal can allow food,sugars,bacteria,...ect, to decay the tooth.Although the root is gone you still have to protect the tooth structure, even though its under a crown. Or should be under a crown.
yes
Each tooth consists of two main portions - the crown, which projects beyond the gum, and the root, which is anchored to the alveolar process of the jaw. Glossy, white enamel covers the crown.
Retraction cord is primarily used when the margin of the crown (where it meets natural tooth structure) will be below the gumline. If the point at which the crown meets the tooth is above the gumline, cord is not generally used.
The crown is superior to the neck of the tooth
have it filled again. Or have a crown placed. When the root is removed the tooth is dead, making it brittle. there is no blood supply keeping the tooth alive anymore. A crown will keep the remaining tooth structure together so it doesn't fall apart.
The part of the tooth that is covered with enamel is the crown.
No, you should not be able to see an old dead tooth once a crown has been fitted over it. The crown should cover the entire tooth, including any discoloration from the dead tooth, providing a natural appearance. If you can still see the old dead tooth, it may indicate an issue with the crown placement or material.
The section of a tooth that extends from the incisal edge to the crest of the gingival is known as the clinical crown. It is the term loosely used to refer to the part of the tooth that is visible in the mouth.
The part of a tooth that is exposed and above the gum is called "crown", not to confuse with a crown that is prothesis to restore a heavily damaged tooth. The part of a tooth that is hidden inside the bone is called "root".
Fluoride varnish is usually what is used in a mouth with porcelain crowns, and is safe to use on porcelain crowns, though direct application of the varnish is usually not necessary, since the porcelain crown is not your actual tooth structure.
