Restoration With Caps / Crowns & Bridges

What Is Crown And Bridge Treatment?

Crown and bridge treatment is a long-term method of conserving teeth(with crowns) or replacing missing teeth (with bridge)


A crown is custom made precision item that is cemented over your tooth or implant to completely cover it. In many instances there is simply insufficient tooth substance to allow the direct placement of fillings or veneers to disguise cracked and discoloured teeth. Crowning of such a tooth maybe the only viable option, to allow function and maintain premier aesthetics. Crowns can hold together portions of a fractured tooth, support dental bridges to fill gaps created by missing teeth and provide longevity to heavily restored teeth. Some people refer to dental crowns as caps. Dental crowns are similar in shape to dental veneers except that crowns cover all the surfaces of a tooth whereas veneers only cover the visible outside surface of the tooth.

Why are they used?

Crowns are prescribed as a part of a treatment to restore teeth that have:

  • Undergone root canal treatment
  • Severe tooth surface loss
  • Been heavily restored
  • Poor aesthetic appearance
  • Replace existing crowns with poor appearance
  • To protect heavily restored teeth from breaking
  • To restore broken down teeth and prevent further breakage


A bridge is used to restore a gap created by one or more missing teeth; literally bridging the gap. Many types of bridges exist; in essence they are all fixed and can only be removed by a dentist. Traditionally bridges have relied on natural teeth to support them however, with advances in science and technology,Dr.Preeti's TOTAL SMILECARE offers implant supported bridges, with the advantage of spanning larger gaps. Traditional bridges involve preparation of the supporting teeth to receive a crown; the gap is closed upon cementation of the final bridge with a life like ceramic pontic.

Why is it used?

Losing a tooth can be of social and psychological concern. Teeth are lost for a number of reasons including: Dental decay, Periodontal (gum) disease or Trauma (injury or accident).

These Missing Teeth need to be replaced to ...

  • Help restore and maintain the natural bite.
  • Prevent unnatural stress on other teeth.
  • Help keep opposing teeth in their proper place.
  • Prevent shifting and tilting of adjacent teeth.
  • Help prevent further dental decay and periodontal (gum) disease.
  • Maximize your smile, speech and chewing function.


Various types of crowns are offered at Dr.Preeti'TOTAL SMILECARE, and their cost depends on the material of choice, time taken, complexity of work and laboratory used.

All porcelain

(Emax is our preferred indirect restoration) – White and incredibly aesthetic, often indistinguishable from natural teeth. It is strong and is also capable of chemically bonding to the tooth. Produces a very natural result.

Ivoclar Vivadent’s patented lithium disilicate material is truly a revolution for the dental industry. Never before has a material been able to combine high strength, high aesthetics and ease of use into one product, until now. IPS e.max is a lithium disilicate glass ceramic that has optimized translucency, durability and strength for full anatomical restorations. The opalescence, translucency and light diffusion properties of IPS e.max lithium disilicate were all designed to replicate natural tooth structure for beauty and undetectable restorations.


Zirconia is the strongest crown material on the market today. The Zirconia material typically used by most manufacturers is atetragonal polycrystalline zirconia, partially stabilized with yttrium oxide. Zirconia materials typically have strengths of over 900 MPa.

Porcelain Bonded to Metal

White porcelain bonded to a metal sub-structure. The metal gives strength whilst the porcelain gives the white colour. Not as natural looking as emax and zirconia crowns. The metal substructure may be NON – PRECIOUS orPRECIOUS metal depending on the patient’s choice. Precious metal is generally preferable as it is more biocompatible with the gingivae (gums) leading to less inflammation and is less prone to corrosion. The weak point here is the bond between the porcelain and metal, and over time the porcelain may break away from the metal. Also, as gums recede with age, a black line may be seen above the crown and this leads to an unsightly smile. This blackness is the metal in the crown. This does not occur with all porcelain/ceramic crowns.


At the first appointment a thorough oral examination, evaluation of your dental history and necessary X-rays are completed. The diagnosis is based on these three factors. Once it has been determined that crown and bridge treatment is indicated, you will be set up with a series of appointments. Note: It’s important that you keep all of these appointments.

You see, your treatment occurs in a planned sequence. Missing or postponing your appointment may cause treatment delays, allowing further tooth movement before treatment can be completed.

The tooth or teeth to be treated are numbed with an anesthetic. Next, during the preparation phase, your tooth or teeth to be crowned are trimmed down. This allows sufficient space for the crown or bridge to fit. After this preparation stage has been completed, an impression of that area of your mouth is taken. Your teeth will be fitted with temporary coverage until your next appointment.


At the following appointment, the crown or bridge is adjusted for proper fit, prior to permanent placement. It is often necessary to fine trim and polish the new crown or bridge.

Other factors we consider include:

Esthetics – colour match and appearance
Function – chewing and biting accuracy 
Tissue compatibility- the contour of the prosthesis must allow the surrounding tissue to conform to a natural, healthy position.


At Dr PREETI’S TOTAL SMILECARE, we expect our crowns to last for over 15 years and we provide a 5 year guarantee against crown breakage. Our treatment addresses both aesthetic and functional needs.
