CROWNS
|
|
A crown is a restoration that covers, or "caps," a tooth to restore it to its normal shape and size, strengthening and improving the appearance of a tooth. Crowns are necessary when a tooth is generally broken down and fillings won't solve the problem. If a tooth is cracked a crown holds the tooth together to seal the cracks so the damage doesn't get worse. Crowns are also used to support a large filling when there isn't enough of the tooth remaining, attach a bridge, protect weak teeth from fracturing, restore fractured teeth, or cover badly shaped or discoloured teeth. Crowns may be placed on natural teeth or dental implants.

Types of crowns available
|
|
Metal Crowns containing various percentages of gold. These crowns look very life-like, distinguished by a very good fit due to better casting of gold containing alloys. Also, these metals are very highly polished which prevent bacteria living in micro-pores from colonizing along the edge of the crown. Thus the gum around such crown stays clean and healthy.

|
Porcelain Crowns fabricated from different porcelain/ceramic materials. Lately, they proved to be as strong as conventional crowns, with better aesthetics. Still, there are several factors that need to be taken into consideration when choosing this kind of crown. The most important being your bite - the way your teeth come together, and the need to cut a lot of the tooth structure away to provide for adequate thickness of such crown.

|
We do not recommend porcelain-fused metal crowns, where the inner layer of the crown is a non-precious metal. Although this traditional crown is much cheaper, the disadvantages of using such a metal are the following: poor aesthetics - unnatural looking crown with gray line along the gum-line, gum irritation in people with metal allergies; this metal alloy usually contains beryllium, known to cause cancer.

Using the most advanced dental technology we can develop Porcelain fillings, veneers and crowns that are computer generated and fitted with precision and accuracy.
Typically this involves a single appointment - this means no messy temporaries that can come off. We eliminate inconvenience and the process is minimally invasive.
A natural looking and biocompatible ceramic material is metal free meaning eliminating unsightly black gum lines.

Root Canal
You may have root canal disease if you are experiencing the following symptoms?
- Lingering sensitivity to either hot or cold or liquids
- Sensitivity to sweets
- Pain from biting pressure
- Pain that is referred from a tooth to another area, such as the neck, temple, or the ear
- Spontaneous toothache i.e. while reading a magazine, watching television, etc.
- Constant or intermittent pain
- Severe pain or throbbing pain
- Pain that may occur in response to atmospheric pressure changes, i.e. when flying or scuba diving
- Pain that may occur in response to postural changes, i.e. when going from a standing to a reclining position
- Swelling
The Benefits
- Stops the pain.
- Prevents bacteria and pain spreading to the jaw bone.
- Keeps the original tooth instead of replacing with denture, implant or bridge.
Illustrations: Root Canal Treatment from Start to Finish
 |
1. A DEEP INFECTION
Root canal treatment is needed when the tooth's root becomes infected or inflamed through injury or advanced decay. |
|
2. A ROUTE TO THE ROOT
The tooth is anesthetised. An opening is made through the crown of the tooth to the pulp chamber. |
 |
 |
3. REMOVING THE INFECTED/INFLAMED TISSUE
Special files are used to clean the infection and unhealthy pulp out of the canals. Irrigation is used to help clean the main canal (called lateral canals). Treatment may take several appointments depending on how complex your tooth is due to its shape, the location, length and curvature of the roots. |
|
4 . FILLING THE CANALS
The root canals are then sealed with a filling material to prevent re-infection or contamination. |
 |
 |
5. REBUILDING THE TOOTH
A temporary filling material is placed to seal the opening until the tooth is ready to be prepared for a crown. A crown, sometimes called a cap, is made to look like a natural tooth, and is placed on top. |
|
6. EXTRA SUPPORT
In some cases, a post is placed to give the crown extra support. |
