What are tooth colored crowns?
These are a type cosmetic crown which is made purely from ceramic and no other material.
The defining feature of these crowns is that they are made from a translucent material which is attractive to look at and blends in well with the rest of your teeth. This is in contrast to other types of crowns such as the porcelain fused to metal.
There are two main types of all-ceramic crowns:
Why are tooth colored crowns used?
In general dental crowns are used to:
- Protect weakened tooth (eg. After root canal treatment) from fracture or to hold together parts of a cracked tooth.
- Cover misshapened or severely discolored teeth.
- Cover a dental implant.
- Make a cosmetic modification
Tooth colored crowns are used specifically in cosmetic modification as an alternative to metal-ceramic crowns due to their translucency and natural appearance.
How are tooth-colored crowns made ?
The dentist will re-shape and taper the tooth to allow the crown to fit snugly over the top. An impression is then taken of your teeth with dental putty. This mould is sent to a dental laboratory where it will be used to fabricate a new crown. It takes about 1-2 weeks for this to happen so the patient will be fitted with a temporary crown in the mean time. Once the crown is ready the patient will be asked to return for the fitting. The crown will be inserted and its shape and color compared to the rest of the teeth. It is then fixed in place with a dental adhesive or cement.
How long do dental crown last?
On average, dental crowns last between five and 15 years. The life span of a crown depends on the amount of “wear and tear” the crown is exposed to, how well you follow good oral hygiene practices, and your personal mouth-related habits (you should avoid such habits as grinding or clenching your teeth, chewing ice, biting fingernails, and using your teeth to open packaging).
How to Care of dental crowns?
While a crowned tooth does not require any special care, remember that simply because a tooth is crowned does not mean the tooth is protected from decay or gum disease. Therefore, continue to follow good oral hygiene practices, including brushing your teeth at least twice a day and flossing once a day — especially around the crown area where the gum meets the tooth. Antibacterial mouth rinse can also help.
