Dental crowns are one of the best ways to protect badly damaged teeth. In most cases, crowns are needed on back teeth that may have needed a root canal treatment. For front teeth, the most common reason for the need of a crown is due to trauma . This could be from a childhood playground accident or a sports injury for example. Ouch!

If a front tooth crown was placed many years ago, over time there will have been changes in the mouth including the level of the gums and the shape and colour of the teeth. This often why there is a 'black' line around old crowns where the gum has receded and the underlying root becomes visible. Older crowns will have been made with a metal base, called a metal ceramic crown and the metal can also show as the tissues change.
 

Our case of the month for September 2022 is a lovely smile transformation done the Progressive Dentistry way with invisalign full, teeth whitening & a new front dental crown. When we plan these types of treatments, we often will look at whether the teeth are in the right place first. Why is this so important? Well the reason is simple. If the teeth are not in the right place or well aligned, any cosmetic treatment will be a big compromise. For instance, in the days gone by, there was a fad for porcelain veneers and crowns. If the teeth were wonky to start with, this would mean having to cut a lot of healthy tooth to make the ceramic veneers or crowns. This is not a good idea! For every heavily prepared tooth, around 17-20% of the nerves die. This means root canal treatment and a risk the tooth will not last a life time.
 

Our case of the month for July 2021 is quite a complex one involving multiple ceramic crowns after an accident during the first lockdown. Our patient, Xavier, had a cycling accident where he cracked 3 of his front teeth. Now with any trauma case, there is a certain way to handle the situation and it is important not to rush into a specific treatment. The reason being is that once the teeth and gums have been damaged, the consequences may not be apparent for several weeks or months. Hence the use of provisional materials such as composite and temporary crowns are vital during this healing phase.

Periodontal or gum health is paramount also and we needed to spend some time stabilising the gum health with conventional and laser treatments. Beata Kynsak did a wonderful job using Waterlase i Plus and the Epic 10 diode laser with a complete transformation from inflamed , swollen gums to a pink, firm attached gum line. Laser dentistry, although not new, is still a rarity across our profession but we are firm believers in the technology and have many years of experience highlighting great results. 

Once the gums were stable, provisional crowns were made using a diagnostic wax up. This is where our laboratory, Ceramic Studios, re create the teeth using digital means to provide us with a prototype of the final teeth. We can use this guide to define our preparations of the teeth, make the temporary teeth and allow our patients to see what the final crowns can look like. Our temporary crown material of choice is Luxatemp; the gold standard. 

After some time in the temporary crowns, we were ready to proceed with the final crowns which were E Max all ceramic crowns, again the gold standard when it comes to aesthetics. There is no better. Ceramic Studios did a great job and just take a look at the before and after results:
 

Dental crowns are one of the most common dental procedures but many people are not aware what a crown is exactly. To be very simple, a crown is a new tooth surface that sits over your existing tooth to protect it.
