Dental crowns, or cosmetic crowns, are small caps placed over a natural tooth to correct damage, weakness, misalignment, or discoloration. Crowns help the tooth return to shape, size, and function. These prosthetic dental applications mimic your natural teeth.
One or more damaged teeth can dramatically impact your quality of life. No matter how we look at it, teeth are important. You need them to eat, and you use them to make an impression through your smile. Living with a damaged tooth can influence the way you feel about yourself and the impact you make on others. If you’re living with a smile that doesn’t meet your standards, a crown could improve your health and happiness.

4. Holding a dental bridge in place.
5. Covering misshapen or severely discolored teeth.

7. Covering a tooth that’s been treated with a root canal.
Metal: There are several metals that can be used in dental crowns, including gold, palladium, nickel and chromium. Metal crowns rarely chip or break, last the longest in terms of wear down and only require a small amount of your tooth to be removed. They can also withstand biting and chewing forces. The metallic color is the main drawback of this type of crown. Metal crowns are a good choice for out-of-sight molars.
Porcelain-fused-to-metal: This type of dental crown can be matched to the color of the teeth that’s next to the crown. They have a more natural tooth color. However, sometimes the metal under the crown’s porcelain cap shows through as a dark line. Other cons include the chance of the crown’s porcelain portion chipping or breaking off and the crown wearing down the teeth opposite it within the mouth. This wear on the other teeth specifically affects the teeth that come into contact with the crown on the top and bottom of your mouth when it’s closed. Porcelain-fused-to-metal dental crowns can be a good choice for front or back teeth.
All-resin: Dental crowns made out of resin are generally less expensive than other crown types.
However, they wear down over time and are more likely to break than porcelain-fused-to-metal crowns.
All-ceramic or all-porcelain: These types of dental crowns provide the best natural color match compared to any other crown type. They’re also a good choice if you have metal allergies. However, they aren’t as strong as porcelain-fused-to-metal crowns. They can also wear down the teeth opposite them in the mouth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.
Pressed ceramic: These dental crowns have a hard inner core. Pressed ceramic dental crowns replace the metal liner that’s used in the all-ceramic crown-making process. Pressed ceramic crowns are capped with porcelain, which provides the best natural color match. They’re also more long-lasting than an all-porcelain crown.
