Types of Dental Crowns ; How to Choose Between Them?
Nothing can be more attractive than a healthy, beautiful smile. You must have to take care of your teeth and solve any issues related to it to keep that smile glowing. Sometimes, your dentist may advise you to treat a condition using a dental crown. A crown is a ‘cap’ that covers a tooth, to restore its normal shape and size, to strengthen, to ease the pain, or to improve its appearance.
Your tooth is made up of two parts, one is a root and the other is a crown. The part above the gum line is known as a clinical crown. A cap or dental crown is a restoration that covers the outer side of your clinical crown, to restore its shape, size, and strength, and improve its appearance. Dental crowns may be made from, a metal such as gold or another alloy, stainless steel, porcelain fused to metal, all resin, all ceramic, Zirconia or EMAX
All Metals Crowns
As the name implies these crowns are made up of metal. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down.

How to choose a crown
While selecting a crown, it’s very important to know that there’s no single type of crown that always makes the best choice in every application. The right selection of crowns constantly differs depending on the requirements of the patient’s exact conditions. Here are some examples that can give you an idea of what types of crowns commonly make the best choice in certain conditions.
For front teeth
If your lip line is very high, your front teeth will mostly be on display to others. In this situation, placing an all-ceramic crown(E max) might be the first option because of the esthetics that this kind of restoration can give. Placing a porcelain-fused-to-metal or milled all-ceramic may also give better results.
When only a portion of the teeth is visible, the esthetic demands is reduced and therefore, other characteristics such as strength and durability may be given more importance in the selection process. Porcelain-fused-to-metal, all-ceramic or milled all-ceramic might be considered for this type of application.
For Back Teeth:
- Molars:- If patient’s molars show very little while opening their mouth, the strength and durability can be the main criteria of selecting a crown and in conditions where the appearance of molars is an issue, porcelain-fused-to-metal crowns provide excellent service and are more aesthetically satisfying than all-metal ones. Milled all-ceramic crowns (particularly zirconia) may also be a sensible choice.
- Premolars:- Although premolars usually hold a prominent spot in a person’s smile, they are defined as ‘back teeth’ and it can be expected that they may be exposed to heavy chewing forces. Porcelain-Fused-To-Metal crowns which are attractive in appearance and have a long track record of being strong, durable restorations can be a suitable option.
Do not delay and select the best crown to protect your teeth and enhance your beautiful smile.
