Dental crowns are best described as caps that are placed on top of teeth. Crowns are used to protect, cover and restore the shape of your teeth when fillings don’t solve the problem. This allows you to regain the normal function of that tooth. Dental crowns can be made out of metals, porcelain, resin and ceramics.
Over time, your teeth can get damaged, chipped, or need some restorative work. This can happen for a variety of reasons, like tooth decay, injuries or just wear and tear with use over time. Your teeth can lose their shape or size as a result of this damage. Dental crowns are tooth-shaped “caps” that can be placed over your existing tooth. Think of it like a snug hat for your tooth. The crown when prepared and cemented into place, covers the visible portion of the tooth, restoring the tooth’s shape, size, strength, and appearance.
You may need a dental crown for several reasons, including:
Permanent crowns can be made out of many different materials.
These materials can include:
Your dentist will best advise you on which of the various options are the most suitable and stable option for your dental clinical needs.
You will typically have two visits to the dentists to prepare for a dental crown. In some cases, you may have a dental crown made on the same day in the practice, these are known as Cerec Same Day Crowns.
During the first visit, the tooth that is going to receive the crown is examined and prepared.
X-rays are taken of the tooth and the bone around it.
Your dentist might have to do a root canal treatment before your dental crown procedure if there is any:
This is to give the best outcome to preserving the tooth and crown.
Pulp is the soft tissue inside your teeth that contains blood vessels, nerves, and connective tissue.
The tooth that is receiving the crown will be filed down across the top and sides. This will make space for the crown itself. The amount of tooth that gets filed away depends on the type of crown you have. All-metal dental crowns are thinner and do not need as much of the tooth removed as all-porcelain or porcelain-fused-to-metal crowns. If too much of your tooth is missing — due to damage or decay — a filling material can be used to “build up” enough tooth structure for the crown to cover.
After reshaping the tooth, a paste or putty is used to make a copy (also called an impression) of the tooth that is receiving the crown. Impressions of the teeth above and below the dental crown will also be made. This is done to make sure that the crown will not affect your bite (how your teeth bite together).
The impressions are then sent to a professional dental laboratory. The laboratory will make the crown according to the dentist prescription. The crown is usually returned to us within two to three weeks.
Completing your first visit if it is required, your dentist will make a temporary crown to cover and protect the prepared tooth while you are waiting on the permanent crown, these are not in any way suitable long term as they are temporary. These are not always particularly aesthetically pleasing, as they are merely a protection to the prepared tooth underneath.
At the second visit, the permanent crown is checked and placed and on your tooth. First, the temporary crown is removed and the fit and colour of the permanent crown is checked.
With the advances in dentistry, patients not wanting to wait 2-3 weeks or those who are conscious of having temporaries on their teeth can consider the benefits of Cerec Same Day Crowns.
