Crown or Bridge

" Be glamorous everyday "

Both crowns and most bridges are fixed prosthetic devices.

Unlike removable devices such as dentures, which you can take out and clean daily, crowns and bridges are cemented onto existing teeth or implants, and can only be removed by a dentist.

Crown or commonly known as a cap is a tooth like covering placed carefully over an existing tooth.

A bridge may be recommended if you're missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to shift into the empty spaces, resulting in a bad bite.

The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.

Bridges are commonly used to replace one or more missing teeth.

They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. These teeth (called abutments) serve as anchors for the bridge.

Why is Crown or Bridge necessary?

  • Increases the strength of the tooth esp. in

    • RCT treated tooth

    • Large and deep cavity

    • Fractured tooth

    • Large old fillings

  • Improves the appearance of the tooth

  • Replaces the missing tooth/Teeth

  • Seals the tooth

  • Helps in support of fixed bridges

  • Prevents the adjacent teeth from shifting

  • Keeps the opposing tooth in correct position

  • Enhances your smile

  • Prevents unnatural stress on other teeth

How is treatment performed?

Treatment usually takes around 3 appointments or visits.

First visit

  • Thorough oral examination is done

  • Area to be treated is anaesthetised

  • Next the tooth is carefully contoured and shaped so that the crown has sufficient space for proper fit

  • Then an impression is taken and a temporary crown or bridge is made to protect the tooth/teeth involved till next appointment.

Second visit

  • The permanent crown or bridge is evaluated for fit and aesthetics.

  • Adjustments are done if required

    • Aesthetics:colour and appearance match
    • Function:chewing and biting efficiency
    • Tissue compatibility:relation with gums
  • Crown/bridge is then fixed with temporary cement.

Third visit

  • Final adjustments if any are done.

  • Crown/bridge is now fixed with permanent cement.

Choice of material

Permanent crowns can be made from all metal, porcelain-fused-to-metal, all resin, zirconia or all ceramic.

  • Metals

  • Used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy (for example, nickel or chromium).

    Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down.

    Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.

  • Porcelain-fused-to-metal

  • Dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns).

    However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown's porcelain portion can also chip or break off.

    Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede.

    These crowns can be a good choice for front or back teeth.

  • All-ceramic or all-porcelain

  • Dental crowns provide the best natural colour match than any other crown type and may be more suitable for people with metal allergies.

  • Temporary versus permanent

  • Temporary crowns can be made in your dentist's office whereas permanent crowns are made in a dental laboratory.

    Temporary crowns are made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory.

How long do Bridges last?

Crowns and bridges have a life span of 8-10 years, they do sometimes come loose or fall out before that. In case that happens contact us and bring your crown or bidge along.

The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene.

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 with fluoride toothpaste twice a day and flossing daily.

Also see your dentist and hygienist regularly for checkups and professional cleanings.

Care of the Crown Bridge

Take care of the new crown or bridge as any natural tooth.

Brush and floss regularly!

Crowns and Bridges Post Operative Instructions

You may eat and drink as soon as the numbness because of anesthesia wears off.


A temporary is a crown or bridge that is placed on the prepared teeth while the permanent crown is being made.

The temporary is placed with temporary cement .it is very loosely attached to the tooth so it can come off easily so avoid chewing sticky foods.

Use your toothbrush to clean the temporary as you normally do your other teeth.

If your temporary comes off between appointments, slip it back on and call us so that we can re-cement it for you.


Sensitivity, especially to cold, is common for a time following treatment. For the first few days avoid extremely hot or cold foods and drinks. It is normal to have discomfort in the gums around the tooth after the anesthesia wears off due to the procedure.

If your gums are tender, rinse with warm salt water, dissolving 1/2 teaspoon of salt in one glass of warm water.

Final Crown or Bridge

After the final cementation of your restoration, it may take a few days to get used to the new crown or bridge. If your bite feels uneven, please call us for a simple adjustment.
