Why Do I Need a Porcelain Dental Crown?
We recommend porcelain dental crowns where a tooth has been badly damaged and has lost a substantial part of its original structure. In this case, a filling or inlay or onlay would not be sufficient to fully restore a tooth as there would be a risk of the remaining structure cracking, chipping or fracturing when under stress, for example during normal biting and chewing.
A dental crown completely covers up a badly damaged tooth, right down to and to just below the gum line. This provides maximum protection for the tooth and seals it so bacteria cannot get in and cause any additional damage. At the same time, a porcelain dental crown will restore both strength and structure to the tooth so it looks beautiful and can be used for normal biting and chewing without any risk of cracking.
Porcelain Dental Crowns Types
Your new porcelain dental crown can be made with a metal substructure that is covered up with porcelain to create a natural appearance. The metal substructure is made from precious metal alloy, providing strength to the crown. However there are newer technologies that can be used and which can enable us to create beautiful dental crowns that don’t contain any metal. These are all-ceramic dental crowns and are ideal in circumstances where aesthetics are particularly important. We may suggest choosing this option if you need a crown right in the front of the mouth, or for cosmetic smile makeovers.
The beauty of these all-ceramic dental crowns lies in the way natural light is able to pass through the crown, which is very similar to a natural tooth, creating a dental crown that has a liveliness that closely replicates a real tooth.
No matter which type of crown you choose, it will be made from the very latest and most advanced ceramics available today, to provide high-quality results.
Porcelain Dental Crown Procedure
Your tooth will be prepared under a local anesthetic to keep you comfortable. During preparation our dentist will remove all damaged areas of your tooth, shaping it to provide sufficient room for the crown. Once they are happy with the preparation, an impression will be taken and sent to a dental laboratory so your new dental crown can be handcrafted. It will be made to our exact specifications and in a shade that will blend in beautifully with your natural tooth color. Your tooth will be fitted with a temporary crown until your new restoration is ready to be fitted and cemented in position.
On occasion we may be able to make your crown while you wait using the very latest CADCAM technology that enables us to scan the prepared tooth using a very small camera. This information is transmitted to a computer so our dentist can custom design your new crown. The design is then sent to our on-site milling machine where your crown will be milled from a block of pre-shaded ceramic material. Once the dental crown is milled, it will be hand finished and either polished or glazed to create a natural looking restoration. The crown is then ready to be fitted and cemented in place, so you can expect your appointment take around an hour. The advantage of this type of technology is that there is no need to have a dental impression which can be a bonus for anyone with a strong gag reflex, and you will only need one appointment. We may not always suggest this type of dental crown, particularly if you require multiple dental crowns as part of a smile makeover.
Porcelain Dental Crown Aftercare
You should brush and floss your new crown exactly same way as you would a natural tooth as this will help prolong its life. Regular dental appointments and hygiene appointments are also important for helping to maintain the integrity of your new restoration. With proper care, your new crown could provide many years of trouble-free use before it eventually requires replacing.
