CROWNS & ONLAYS
Over time our teeth begin to weaken and become more susceptible 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 your dentist notices that 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.
Crowns can be made from porcelain, porcelain fused to metal, or a full gold crown. To maintain a natural look and feel a porcelain finished crown is best, as it can be matched to the shade of your other teeth. This will allow it to blend in and appear just like one of your natural teeth.
The process of installing a crown takes 2-3 visits to the dentist. On the first visit the tooth will be reshaped by filing down the enamel so that the crown can be placed over it. You will be given a local anesthetic before this part of the procedure so that you do not experience any discomfort. Once the tooth has been reshaped, a mold will be taken of that tooth and the surrounding teeth. This mold will be sent to a dental lab so that your new crown can be made so that it fits in the spot created for it and looks the same relative to the surrounding teeth. Before leaving, your dentist will fit you with a temporary crown until your permanent crown is ready.
The crown takes about 2-3 weeks to be returned to your dentist. At this time you will have another appointment to place and fit the permanent crown. You will again have a local anesthetic to numb the area and the tooth will be placed using a cement to ensure the tooth sets in place. When you look in the mirror, you will see your old smile back. Crowns are durable and will usually last about 10-15 years. You should care for it as you would any of your other teeth with regular brushing and flossing.

Onlays are often referred to as partial crowns. They use the existing tooth as a base and fit the inlay or onlay onto the tooth. This is done to strengthen the tooth, restore its shape, and prevent further damage. An inlay is done when there is no damage to the cusps of the tooth and the inlay can be placed right on the tooth. An inlay is used when the damage is a little more extensive.
The decayed area of the tooth is first removed during the procedure. A mold of the tooth is then taken and sent to a dental lab. They create a restoration made from porcelain, gold, or a composite resin. The restoration takes about 2-3 weeks to make, so a temporary inlay or onlay will be placed on the tooth for that time. During your next visit the inlay or onlay will be placed into your mouth and set with cement. Your tooth will look natural and you or anyone else won't be able to tell the difference.
Same Day CEREC®
CEREC® is an advanced dental technology that is utilized for the restoration of decayed, cracked, or chipped teeth. CEREC® can create full crowns, inlays, onlays, and veneers. The CEREC® machine crafts a restoration in a matter of minutes. CEREC® restorations are made of compressed porcelain. It is for this reason that they are stronger than laboratory restorations, which are layered porcelain. The most beneficial feature of receiving a CEREC® restoration is that it is accomplished in one visit. In addition to the benefit of a one visit restoration, there is no uncomfortable impression material to bite on or temporary to wear.
The procedure for placement of a CEREC® restoration is very simple. The first step is to remove all decay from the tooth. The doctor will then shape the tooth in preparation to take a digital picture. The tooth is then sprayed with a very fine powder. This allows the digital camera to take an acceptable image. Once this image is captured, the tooth will appear on a computer screen in 3D. This will allow the doctor to design the restoration right in front of you. Once the design is completed, the CEREC® will mill the restoration. This step takes approximately 15 minutes. You can actually watch this process if you would like. When the restoration is finished milling, the doctor will place the restoration. The entire process should take just over an hour.
