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.

A dental crown is a restoration that covers or caps a tooth, restoring it to its normal size and shape while strengthening and improving its appearance. Crowns are necessary when the tooth is broken down to the point where a filling will not be effective.
Benefits Of A Dental Crown
A dental crown can be used for various reasons including covering discolored or misshapen teeth, and in conjunction with bridges and dental implants.
Other benefits of dental crowns may include:
- Holding a cracked tooth together to prevent further damage
- Covering and supporting a tooth with a large filling
- Restoring a broken tooth
Dental Crown Procedure
The dental crown process takes place in two phases or appointments. At the first appointment, the tooth is prepared by filing or reshaping, so the crown can fit in securely and comfortably. The area around the tooth is numbed throughout the procedure with a local anesthetic. After the tooth is prepared, an impression is made of the teeth and gums using a paste or putty. The impression is then sent to a laboratory to make a custom crown, which usually takes two to three weeks. Patients are given a temporary dental crown until the permanent crown is ready. At the second appointment, the new crown is inspected for proper fit and tooth color. The temporary crown is then removed and the new one is cemented onto the tooth.
Types Of Dental Crowns
There are several different methods of crown restoration, each using a different crown material. Different types of crown material include:
Metal crowns are made entirely of a metal alloy that may include gold, platinum, palladium, or other elements. Compared with other kinds of crowns, metal crowns preserve more of the tooth structure. They withstand biting and chewing forces well and rarely chip or break. The biggest drawback of metal crowns is the metallic color.
Porcelain-Fused-To-Metal Or PFM Crowns
PFM crowns can be color-matched to the teeth. Second, only to all-ceramic crowns in appearance, porcelain-fused-to-metal crowns look like normal teeth. In some cases, the metal underlying the crown’s porcelain can create a dark line. PFM crowns tend to wear down opposing teeth more than metal crowns. The crown’s porcelain portion can also chip or break.
All resin crowns are the least expensive type of dental crown. The drawback is that they are more prone to chips and fractures than other crowns and tend to wear down over time.
Ceramic Or Porcelain Crowns
These crowns provide the best natural color of all the dental crowns. They are not as strong as PFM or gold crowns, and they may wear down opposing teeth more than metal or resin crowns. Because they are the most cosmetically pleasing, they are commonly used for the front teeth.
Some patients experience increased sensitivity immediately after the procedure, particularly if the crowned tooth still has a nerve in it. For sensitivity to heat and cold, some patients are advised to use toothpaste for sensitive teeth. Other complications that may occur with dental crowns are:
Pain Or Sensitivity
When Biting This usually means that the crown is too high on the tooth. If this is the case, the dentist will be able to fix the problem by adjusting the crown.
Chip In A Porcelain Crown
Resin can be used to repair the remaining crown. If the chipping is extensive, the entire crown may need to be replaced.
Loose Dental Crown
If the cement washes out from underneath the crown, bacteria can then leak in and cause decay. A dentist should be consulted to resecure the crown to alleviate the problem. In some cases, a dental crown may fall off entirely. If this happens, contact the dentist immediately. The dentist may be able to replace the crown or create a new crown if necessary.
With proper oral hygiene, dental crowns can last from five to fifteen years. Patients should consult with their dentist to see if dental crowns are appropriate for their individual condition.
