If you have suffered damage to your teeth, you might need to consider dental crowns. Crowns, or dental caps, are a long-lasting form of dental restoration that completely covers a tooth or dental implant. Titirangi Dental is dedicated to providing the best cosmetic dentistry and dental care services in West Auckland, and that includes making sure your teeth look and function as they were meant to.
Why Are Dental Crowns Needed?
Our dentists often recommend crowns when the health or strength of a tooth has been compromised by a large cavity or filling. For example, if you have had root canal treatment, you will likely require a crown to cover and protect the weak tooth while providing structure and function. This is often the only way to salvage a damaged and decayed tooth, as well as improve the appearance.
In addition, if you have lost one or more teeth and are having a dental implant installed, you will need a crown attached to the titanium root or implant.
How Do Dental Crowns Work?
Crowns can be a bit more expensive than some other dental restorative solutions, but they are the most beneficial to dental health, making them a worthwhile investment.
They are made in a separate laboratory to fit precisely to your tooth size and bite. They can be shaped to join the tooth in a process called marginal adaptation, which is designed to seal out bacteria. While placing the crown inside your mouth, the dentist can properly contour the contact to the adjacent teeth so that food will not get wedged between them.
What Are Dental Crowns Made of?
There are a number of different crown material options for different situations. Full gold crowns last the longest, as they are cast as a single piece of gold and are less likely to break. These are ideal for back molars.
Porcelain-fused-to-metal crowns (PFM) give you the tooth-like look of porcelain on the top layer with the strength of metal alloy underneath. Although incredibly strong in compression, porcelain used this way may be fragile in tension.
Full porcelain crowns look the most natural. New technology has allowed the bonding of porcelain crowns (no metal) to the tooth sub-structure. This allows for a very strong crown. Above is an example of porcelain ‘Emax’ crowns.
