All-ceramic crowns is used to refer to dental crowns that are made with 100% ceramic. The all-ceramic crowns have increased their popularity in the world of dentistry, they are strong and more aesthetically pleasing than most other dental crowning material. They appear to be glass-like and can blend very well with your natural teeth.

It is so very possible to obtain an exact match of your teeth appearance with the use of leucine reinforced pressable porcelain crowns.

With ceramic crowns, you don’t need to worry about the health of your gums surrounding the crowns. Due to the fact that all-ceramic crowns are biocompatible materials, the gum tissue will be able to stay healthy and whole beside them. It bonds very well, that your gums tissues won’t pull away from your crowns.

Disadvantages of ceramic crowns
When it comes to durability and life-span, there is no any other type of dental crowning material that can be compared to all-metal crowns. (3) In some cases where durability and longevity are vital, ceramic crowns might not be a good choice. The reason why I said this is because, ceramic crowns are more likely to fracture or break when they are not taking proper care of.
How to get a ceramic crown
A ceramic crown can be placed on a tooth just like a traditional crown. It will take two visits to the dentist in order to install a ceramic crown. On your first visit to the dentist office, the dentist will have to check your tooth where the crown will be placed. He will need to remove the decayed portion of your tooth if you had a tooth decay.
The next step is to shapen your tooth enamel to make a room where the new crown will be placed on. After reshaping, the dentist takes impression of the tooth. Dental impression involves the use of paste or putty material to obtain the actual measurement of your tooth. The impression will be used to fabricate your crown later on. After the impression has been taken, the dentist will have to place a temporal crown on your tooth.
On your second visit, the dentist will perform the final placement. The dentist will remove the temporal crown and check the fit of the newly fabricated ceramic crown. He might still need to do some last-minute adjustment before the dental crown will be bonded over your tooth.

How to care for ceramic crowns
Proper maintainance of a dental crown is very important if you want the crowns to last long. However, ceramic crowns are not meant to last forever, but your dentist will tell you how long the crown is meant to last. If you are able to keep to the maintenance guide that is being recommended by your dentist, you can keep your crown safe and strong.
To care for ceramic crowns, you should try to avoid those things that can damage the crowns. Make proper use of your teeth and also practice good oral hygiene. Brush and floss carefully and regularly, most especially around the base of the crown to prevent plaque and bacteria buildup.
Do ceramic crowns have any health risk?
Well, my answer to that question is no. There hasn’t been any case of health problem that is proven to be associated with the use of ceramic crown. Although, it’s possible that some patients might be allergic to ceramic crown, but it’s very rare. Since ceramic crowns are prone to crack if misused, you should be watchful. Harmful bacteria can penetrate inside the crown through cracks and create serious dental problems.
