What are dental crowns?
A dental crown is a cap that comes in a tooth shape to cover the tooth and restore its size, shape, strength, and improve the appearance of a tooth. When they are cemented, it covers the entire visible part of the teeth from the gums upwards.
What are the uses of dental crowns?
Dental crowns are used to protect a weak tooth from breakage. It is also used to hold the parts of a cracked tooth together and restore a tooth that has already been broken or is severely damaged. It is also used as a cover for a tooth with a large filling, a tooth that is misshaped or is discoloured as well as covering a dental implant and keeping a dental bridge in place. A dental crown makes a great cosmetic modification for anyone who wants it.
What are the different types of dental crowns?
There are stainless steel crowns which are prefabricated and used on permanent teeth as temporary device. There are also metal crowns that are best in protecting against biting and chewing. They are also known for its longevity before it starts to wear down. Another is called porcelain-fused-to-metal dental crowns. They can look more closely like the adjacent natural teeth but they easily chip off or crack. These are great for front and back teeth.
The all-resin dental crowns are cheaper than the other types but they easily wear down, faster than the porcelain-fused-to-metal kind. It is more prone to fractures. The all-ceramic or all-porcelain is good for those who have allergies to metal. The downside is that they are not as strong as the porcelain-fused-to-metal as well.
You can also find digitally constructed dental crowns and these are called Zirconia or milled crown. They are produced with the use of a software and hardware inside a dental lab.
What is the right way to take care of a temporary dental crown?
There are certain precautionary measures that have to be practised to avoid damage on the temporary crown until the permanent one is done. It is better to avoid foods that are sticky and chewy as it has the tendency to grab and pull the dental crown off. Try to minimise the use of that side of the mouth where the crown is located and avoid hard-to-chew foods since it may dislodge or chip off the crown. When flossing, it is better to slide the floss than to lift it out since it may dislodge the crown.
Are there possible complications in using the dental crown?
You may feel some hot or cold sensitivity on the tooth that has been crowned after the procedure. Crowns may also fall, chip, and loosen off. It is also possible for you to develop an allergic reaction towards metal. You might also find a dark line underneath the crowned tooth which is next to the gum line.
How long would a dental crown normally last?
Often, it takes around 5 to 15 years for the crown to wear off. It all depends on your oral hygiene practices and some mouth-related habits you have.
