Crowns - Restoring Damaged Teeth
Crowns can help to bring back the natural charming smile on the patient’s face and help prevent any future oral problems.
We offer the best restorative procedures to repair teeth that have suffered from decay and damage. Dr.Erika Barta and Dr.Reka Toth-Tarczali are highly skilled in placing dental crowns at their practice. They use the latest technology to provide high-quality, convenient treatment. Dental crowns have become a pretty standard way to repair damaged teeth. After all, they are durable and look just like natural teeth, so there are a lot of benefits to choosing them.
A dental crown is a covering that fits over a damaged, decayed or unattractive tooth. It can even replace a tooth entirely as part of dental bridgework. Crowns strengthen damaged teeth, allowing them to function normally again. When crafted from today’s high-tech porcelains (dental ceramics), crowns are virtually indistinguishable from natural teeth. They can even be designed to improve upon a tooth’s original appearance.
A crown completely covers a tooth above the gum line. This is in contrast to a dental veneer, which only covers a tooth’s front surface and needs natural tooth structure to support it. Therefore, if a tooth is missing a significant amount of structure above the gum line, a crown would be the restoration of choice.
There are several benefits from wearing a crown which include:
- Repair a damaged or broken tooth as a result of an accident or injury.
- Hides the results of teeth grinding by building the tooth back up to help function properly.
- Strengthens the tooth after root canal treatment.
- Extra protection for the tooth after a large filling
- Replace discoloured fillings.
- Prevents the further spread of decay in a weakened tooth.
- Repair a tooth or teeth which are too severely damaged for direct composite bonding.
- Can hold a bridge or denture in place
Plus a crown is an important part of the dental implant procedure in which it is joined to the implant via a device called an ‘abutment’.
Many people choose to wear a crown as a result of an accident but others also choose them for aesthetic reasons in cosmetic dentistry to improve the appearance of their teeth.
The porcelain fused to precious metal crowns
- Are a traditional type of crown often used in bridges plus crown and bridge cases.
- They are often fitted onto back teeth and are considered a strong, robust type of crown.
- They consist of a metal interior or base which is fused to porcelain crowns. The metal interior can be produced from a range of metals, e.g. alloy and this is what gives this crown its strength.
- They are often cheaper than other types of crowns, for example all ceramic crowns.
Zirconia Crowns (metal-free)
This type of crown is made from Zirconia, a very strong material which is compatible with the human body. You can read more about Zirconia crowns here.
E.MAX® Crowns (all-ceramic, metal-free)
The E-Max crown is a type of all-ceramic crown which is preferred for its longer lasting, aesthetic qualities. You can read more about E.MAX® Crowns here.
It normally takes two appointments.
The first is for preparing the tooth, taking impressions, recording the shade of your teeth, and fitting a temporary crown. The second appointment is for cementing the permanent crown.
In order to place a crown, the dentist will :
- File down the tooth to make room for the crown.
- After filing down the tooth, the dentist will use a piece of thread or cord to push down the gum around the tooth.
- Then the dentist will take an impression (copy) of the tooth with a rubber-like material. The impression material sets in about five minutes. Then it is removed. Your dentist will also take an impression of the teeth above or below the tooth that will receive the crown. The purpose is to make sure the crown will fit into your normal bite.
- The impressions are sent to the laboratory, where the crown is made.
- During that time, you will have a temporary crown placed. These crowns are usually made of plastic. They made by the dentist during your preparation visit. Then the dentist fits the temporary crown to your tooth.
- At a second visit, your dentist will remove the temporary crown and test the permanent one. Once the crown is ready, it will be tried in place and small adjustments made to ensure a comfortable bite is maintained.
- Once you and your dentist are happy, the crown is cemented into place.
No. Local anaesthetic is used and the preparation should feel no different from a filling. If a tooth does not have a nerve following root canal treatment, then a local anaesthetic may not be needed.
Your dentist will match the crown as closely as possible to the other teeth, in size, shape and colour. This should ensure that it fits comfortably and looks natural.
The crown can last between 10 -15 years if good oral hygiene is maintained, depending on the condition of the original tooth. The crown itself cannot decay, but decay can start where the edge of the crown joins the tooth. Additional care should be taken to keep the crown and surrounding area clean.
- Crowns require the same conscientious care as your natural teeth.
- Be sure to brush and floss between all of your teeth — restored and natural — every day to reduce the build up of dental plaque.
- When you have crowns, it is even more important to maintain your regular schedule of dental hygienic cleanings.
- Avoid using your teeth as tools (to open packages, for example).
- If you have a grinding habit, wearing a nightguard would be a good idea to protect your teeth and your investment.
