Why replace missing teeth?

Gaps left by missing teeth eventually cause the remaining and adjacent teeth to rotate or shift into the empty spaces, resulting in a bad imbalanced bite. This leads to cavities, gum disease , bone loss, weakening of remaining teeth , wrinkled appearance and temporomandibular joint (TMJ) disorders.

  • 1. Supra eruption of opposing tooth.
  • 2. Bone loss
  • 3.Drifting of adjacent teeth
  • 4. Cavity
  • 5. Bone loss
  • 6. Weakening of tooth

How do Crowns Work?

A crown is used to entirely cover or "cap" a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Crown may be made of metal, porcelain, or newer restorative materials like metal free ceramics . Porcelain or ceramic crowns can be matched to the color of your natural teeth. Other materials include gold and metal alloys.These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and aesthetic .

Dr. Aman Arora may recommend a crown to:

  • Replace a large filling when there isn't enough tooth remaining
  • Protect a weak tooth from fracturing
  • Restore a fractured tooth
  • Attach a bridge
  • Cover a dental implant
  • Cover a discolored or poorly shaped tooth
  • Cover a tooth that has had root canal treatment

Types Of Crowns

1. Porcelain-Fused-to-Metal Crowns :

Porcelain-fused-to-metal crowns provide a strong, durable, and esthetic treatment option. One of the key factors for the esthetic and functional success of this type of crown is ensuring the preparation of the underlying tooth structure to provide adequate space for the appropriate thickness of the material selected. Additionally, the artistic skill of the laboratory technologist creating the crown will determine its esthetic appeal.

One consideration in the porcelain-fused-to-metal crown is that these crowns may tend to show the underlying metal or gold margin at the gum line as gums recede over time. Some patients opt for this type of crown but replace the crown at a later date in order to maintain a higher esthetic benefit

2. All-Ceramic Crowns :

The predominant material choice for all-ceramic crowns today is either zirconia , or aluminous materials. They provide a metal-free esthetic option with a number of benefits.

By eliminating the need for the supportive metal core, an esthetic all-ceramic crown can be created with a reduced thickness of material. This makes them a more favorable treatment choice in areas with limited space. Additionally, the elimination of the metal core allows for light transmission through the porcelain for better optical, life-like properties and a higher level of esthetics. All-ceramic materials continue to evolve in strength and durability, but caution should still be exercised for areas of the mouth requiring heavy function.

The Zirconia manufacturers have worked on crowns that are custom milled from solid blocks of Zirconia and baked at extremely high temperatures so that the completed crown is pretty near unbreakable. Although such crowns are well tolerated, last long and are a good technical choice, many consumers much prefer to have a natural effect that blends into the overall smile. Many also don't want metal in their mouths. In most cases Dr.Arora will give a choice between a PFM Crown and a Zirconia Crown.

Advantages Of Zirconia Crowns:

Strength and Longevity : Zirconia is virtually indestructible whereas Porcelain crowns are prone to chipping. Crowns have a lifetime of around 10 years. Zirconia should last more.

Cosmetic : Have you ever seen people with a large unsightly black line above their gums? Up until recently most crowns are Porcelain which is Fused to a Metal base. Over time, the metal begins to show more and more and the restoration can look opaque and monochromatic, with the tell tale dark grey line at the crown join.

The Zirconia Crowns not only look more translucent, but are much stronger than the Porcelain fused to the Metal posts. The Zirconia crowns are milled from a single block of crystal and can be up to five times stronger than a porcelain fused to metal crowns.

Less tooth Removal :In cases where there is not much room for porcelain build up - for example if an tooth abutment is already quite bulky, a Zirconia Crown can be used because it provides more strength in less volume than a porcelain fused to metal crown.

Disadvantages Of Zirconia Crowns:

As with everything in life, all these benefits come with a price. They are more expensive than PFM Crowns.

3. Metal Crowns :

Although not as popular a treatment choice for esthetic reasons, metal crowns are still indicated in some instances. For example, patients with strong bites and those with parafunctional habits (such as grinding or clenching) might be better served with metal crown. The traditional restorative material can provide stronger support to the remaining healthy tooth structure. Metal crowns offer a level of durability that is appropriate for teeth located in the back of the mouth (such as the molars), where they will not be highly visible. Metal crowns tend to offer greater longevity and require less preparation than porcelain-fused-to-metal crowns.

How do Bridges Work?

A bridge may be recommended if you have missing one or more teeth.. Bridges can be used to replace a small number of missing teeth if the neighboring teeth are sufficiently strong. The number of missing teeth, condition of the neighbouring teeth, condition of the supporting gums and bone are all important factors which need to be assessed prior to making a bridge.

How are Crowns and Bridges Made?

Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth/teeth, Dr.Arora will take an impression to provide an exact mold for the crown or bridge. If porcelain is to be used, he will determine the correct shade for the crown or bridge to match the color of your existing teeth.
Using this impression, a dental lab then makes your crown or bridge, in the material your dentist specifies. A temporary crown or bridge will be put in place to cover the prepared tooth while the permanent crown or bridge is being made. When the permanent crown or bridge is ready, the temporary crown or bridge is removed, and the new crown or bridge is cemented over your prepared tooth or teeth.

How Long do Crowns and Bridges Last?

Crowns and bridges done by Dr.Aman Arora can last a lifetime, provided a good oral hygiene is maintained. A bridge can lose its support if the teeth or bone holding it in place are damaged by dental disease. Keep your gums and teeth healthy by brushing twice a day . Also see Dr.Arora every 6 months for checkups and professional cleanings.
