A dental crown is a tooth-shaped “cap” or cover that we place over a tooth that is badly damaged from trauma or decay to restore its shape, strength, size and functionality. We also use them for cosmetic reasons to improve a tooth's appearance with natural, life-like results. Crowns are generally handcrafted by dental laboratory technicians using high-quality dental porcelains (ceramic materials) that are made to fit on precise replicas (molds) of the prepared teeth. In our office, we generally make temporary crowns to protect the teeth to keep them comfortable and functional while the permanent crown(s) is being made. And once a crown is placed (cemented into position), it fully encases the entire visible portion of the tooth that lies at and above the gum line.
When Are They Necessary?
There are many reasons a crown may be needed. Some of these include:
- To repair a tooth that is worn down, broken or badly damaged by decay or injury.
- To restore a tooth so severely damaged by decay that the tooth's structure is no longer intact enough to place a filling or where a filling can't restore the tooth to its former strength.
- To protect a tooth that has minor cracks or fractures from further damage.
- To create a bridge to replace a missing tooth, in which the teeth on either side, known as abutments, must be “crowned” to attach to the “pontic” (from the French word, “pont” that means bridge).
- To create the visible part of the tooth that sits atop a dental implant.
- To improve the appearance of a tooth providing a more appealing shape and color.
It is always good to be prepared before you have any dental or medical procedure. Make sure that you are informed and know what to expect to make you as comfortable as possible. We recommend that you have a list of questions with you to ask us during your consultation. If we inform you that you need a crown, consider asking any or all of the following questions:
- Am I a good candidate for a crown?
- Can you do a computer-generated mock-up of my new smile with crowns? (This question is only applicable if the crown is for a front or visible tooth.)
- Is there a way that I can “test-drive” my new smile and crown(s) before making them permanent?
- How long will the entire process take from my first appointment through completion?
- What are the risks, benefits and alternatives associated with the type of crown(s) you are recommending?
- Is there any discomfort associated with crown procedures?
- Will I need or receive any type of sedation when you prepare (drill) the tooth or teeth for a crown?
- Is what you are recommending commonly done?
- Can you show me some before and after photos of cases that you have done?
- How much will my crown(s) cost?
- Will my insurance cover all or a portion of the cost?
- How long can I expect my crown(s) to last?
- Will there be any maintenance required with my crown(s)?
When it comes to restoring both the beauty and functionality of a smile, two of the most commonly used techniques are porcelain crowns and veneers. Why? They consistently deliver beautiful, natural-looking results that are permanent and require very little maintenance. And while they have many things in common, they also have just as many differences.
Here are some facts that apply to both porcelain veneers and crowns:
- Both enable changes to a tooth's color and shape.
- Dental laboratory technicians use precise molds made by our office to hand-craft porcelain veneers and crowns.
- Both are made using high-quality dental porcelain.
- Neither respond to tooth whitening products — the color of the veneer or crown remains the same color as the day it was placed.
- Neither procedure is reversible once completed.
Here are some of their differences:
- Crowns are used to replace a larger amount of tooth structure while veneers are thin shells that are placed over the front surface of teeth.
- Veneers require much less tooth preparation (reduction by drilling) than crowns.
- Crowns allow for greater change of tooth shape, while veneers allow for more minor changes.
- Crowns are generally used to restore teeth that have lost tooth structure from decay or trauma.
- Veneers are generally used where teeth are structurally healthy and intact, but color and shape change are required.
- Veneers are used mostly for teeth that are visible when smiling, while crowns can be used to restore virtually any tooth.
