Crowns or a “cap” are recommended to strengthen teeth after they have undergone extensive treatment which have compromised their natural strength against the pressures of general biting. Crowns are aesthetically pleasing because they come in a porcelain material which is colour matched to your own natural teeth.
When are crowns recommended?
- Post root canal therapy. When teeth undergo a root canal treatment, the inside blood supply (or “nerve”) has been removed leaving the tooth in a more brittle condition. This could be compared to a tree which has died, it is no longer alive and the branches easily break off. A crown will reinforce the tooth structure and provide the strength it needs for long term.
- Cracked Tooth Syndrome. When there is a tooth that has suffered a crack or fracture and is causing pain when eating, it is recommended to place a crown to stop the crack reaching the “nerve” of the tooth. If the crack is left to progress, it will not only be painful but the crack will open up into the “nerve” allow a port for the bacteria to enter.
- When a tooth has had a large filling placed, it has less natural tooth structure for strength and is at risk of breaking at weaker points. To avoid that happening, we recommend a crown to be placed.
CEREC- CAD (Computer Aided Dentistry) CAM
Cerec -CAD CAM comprises of the use of computers in creating state of the art crowns or fillings (restorations) in a strong ceramic material which is long lasting, tooth coloured and biocompatible. The restorations are completed in one appointment where the computer scans the prepared teeth, designs the restoration and finally mills the restoration which is then ready to cement.
Veneers are a thin shell of either porcelain or tooth coloured resin material, that are bonded to the front surface of the tooth. They are used to improve the appearance of teeth as they are able to straighten, whiten or can change the shape of the tooth altogether. The results are natural and aesthetically pleasing.
Porcelain versus Resin Veneers:
Porcelain are more natural looking , smoother, thinner and stronger. However, to place a porcelain veneer the tooth needs to be prepped more so than the resin veneers. Cost wise, porcelain are therefore more expensive as the resin have a shorter life span and can have difficulty making dark teeth.
Veneers need to be checked and cleaned professionally on a regular basis.
Tooth Coloured Restorations
Tooth coloured restorations (white fillings) are a resin based material that come in a range of shades, which will match to any natural tooth colour. These types of fillings chemically and mechanically bond to the tooth therefore allowing our dental professionals to be as conservative as possible when removing tooth structure.
Removal of amalgam restorations (silver fillings) and replacement with either a tooth coloured filling or porcelain inlay/onlay, is a choice that you should make with your dentist or oral health professional.
Most commonly, amalgam restorations are replaced due to cracks forming in the remaining tooth structure around the filling or due to new decay beneath the filling. They may also be replaced because of the lack of aesthetics in comparison to the tooth coloured materials.
Stains on the teeth can happen due to many factors, including lifestyle, aging or trauma.
Most common factors are:
- Red wine
- Lack of proper oral hygiene practices at home
Whitening is a great alternative to the more invasive cosmetic treatments, to achieve a whiter and brighter smile. A consultation with your dental professional would be needed to rule out any current dental diseases or gum issues before treatment is begin.
The whitening process occurs over two appointments:
1. Impressions of your teeth are taken to prepare a custom whitening tray that you will use to place the whitening gel inside. These trays are made especially for your mouth and have a sponge layer inside to spread the whitening gel evenly and prevents spillage onto your gums.
2. Your custom trays are fitted and the whitening kit are delivered to you. Your dental professional will prepare a detailed explanation on how you will apply the whitening system and how long you will need to do this.
It is important to be aware that each individual is different and everyone's teeth will whiten according to how much their natural teeth will allow. Surface staining caused by foods, drink and smoking are easily whitened. However, the deeper the staining is within your tooth structure, the success rate may be reduced.
Tooth sensitivity is a common problem associated with whitening, especially if there is already a pre-existing sensitivity with your natural teeth. In this case, whitening should be spread out over a longer length of time, coupled with a de-sensitising agent such as sensitive toothpaste or Tooth Mousse.
