Over time our teeth begin to weaken and become more prone to problems such as decay, cracks, discoloration and others. If you feel your smile isn’t what it once was, crowns can help you recover your smile. If a tooth is decayed or seems weakened/cracked a crown may be necessary to make sure that there are no additional problems with the tooth. In cases like this a filling or bonding will not be sufficient.
Dental crowns are used to strengthen and improve the shape, size or colour of teeth. They can support broken or weak teeth or those with large fillings; provide a smooth, strong, attractively contoured surface for stained, misshapen or otherwise abnormal teeth; and aid in the support of bridges and other implants. This type of restoration is used for a long lasting correction of dental problems that cannot otherwise be repaired. Crowns can often last for 15 – 20 years, which is considered permanent for a dental treatment.

How Are Crowns Fitted?
The dental crown placement process generally requires minimum two appointments. The first appointment is designated for cleaning and preparation of the portions of the tooth that have been damaged, and also removing a small bit of natural tooth enamel to make room for the dental crown. Dr. Kaviani will make an impression of the tooth for customization of the cap in a lab.
Your custom designed and individualised crown will be created so that it not only fits snugly over your tooth, but within the surrounding teeth as well. A temporary dental crown will be positioned over the tooth for protection, and to maintain your smile's natural appearance, until your next appointment.
After the laboratory has crafted your customized crown, you'll return for a second appointment. The temporary crown will be taken out, and the permanent crown placed.
“Trial smile” is the temporary crowns that Dr. Kaviani has designed prior to fabricating the final crowns. These temporaries allow you to “test drive” the smile design for a period of time,
Dr. Kaviani will work with you on refining the final design and then there are no surprises at the end. Your trial smile is actually the prototype for the final design and is created based on your vision of the type of smile that will make you look your
The “trial smile” is usually worn for several days before you and your cosmetic dentist; Dr. Kaviani makes the final decisions as to the final smile design.
A very important concept is that by wearing the “trial smile” first, you are given ample opportunity to accept or change key components in the design of the smile, especially the colour, shape of the individual teeth, and the length of the teeth.
Different Types Of All - Ceramic Crowns
This type of crown is made from zirconia, a very strong material which is compatible with the human body. Zirconia is a type of crystal which is long lasting and indestructible.
This is a type of all-ceramic crown with an appealing translucent colour which is combined with extra strength and durability. It is suitable for damaged, stained or poor quality teeth.
Procera is a milled ceramic on the inside with more traditional porcelain baked onto the outside. It has an exceptional strength , but the ceramic core is opaque white, so it isn’t as natural-looking as the more translucent materials.
Lava is similar to Procera, but the milled ceramic on the inside is more translucent than an opaque white material. The Zirconia is shaded, and then the final aesthetics is achieved in the baked-on outer layer.
The Empress crown
Empress is not porcelain; it is more like a glass. The Empress material is cast rather than baked as a conventional porcelain crown is. The colour in Empress is mostly baked on the outside and can be very beautiful.
InCeram is made of very dense and very tough aluminous porcelain. It also has excellent aesthetics, but is more opaque than conventional porcelain
