Dental Crowns

What are dental crowns?

 

A dental crown is a tooth-shaped “cap” that is cemented onto existing teeth or implants. Crowns can be used to strengthen and protect a damaged or cracked tooth, and/or after a tooth has had root canal treatment done,  and/or 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.

What are dental crowns made of?

 

The most popular type of dental crown in the market today is Zirconia. Other materials include gold and metal alloys, other types of porcelain (lithium disilicate) or resin-ceramic hybrids. Porcelain can also be combined with zirconia or metal bases.

Stronger than all-ceramic crowns.
Strong enough to be used in thin section or on back teeth.		More expensive than all-ceramic crowns.
Not completely unbreakable.
Porcelain-fused to-metal crownLess expensive than pure ceramic or zirconia crowns.
Opacity may be useful for covering a discoloured tooth.
Very strong.
Internal metal surface is compatible with titanium implant surface.		Dark grey discolouration can occur at the gum line due to metal show through.
Looks opaque so may not blend in with natural teeth
Acrylic crownCheap.
Easily adjusted to match neighbouring teeth.
Useful as temporaries.		Not durable.
Translucent: dark underlying tooth structure may show through.
Metal alloysVery long lasting.
Softer metals like gold alloy do not cause aggressive tooth wear, perfect for patients who suffer from severe night time grinding.
Stainless steel crowns are used for baby teeth that need reinforcement.		Gold alloys are expensive,.
Looks un-natural.

Before any dental treatment can proceed, it is extremely important to first consult us to assess if your tooth would indeed benefit from a dental crown.

 

 

Step 1: Preparing your Tooth

 

First, your tooth and the surrounding tissues will be numbed with a local anaesthetic. Decay and any defective old fillings will then be removed from your tooth. The cavity is cleaned and refined. A base filling is placed to seal the tooth from bacteria and to regularize the tooth shape.

 

 

The tooth is then trimmed so the new crown can fit over it and there is sufficient space for the chosen crown material. A mould or digital scan of the tooth is then made and transferred to the dental laboratory. A temporary crown will be made to protect your tooth in the meantime.

 

 

Step 2: Fitting of the crown

 

Once the final crown is ready, the temporary crown will be removed. The crown is then cemented onto your tooth and excess cement will then be removed. We will then check your bite to make sure it is balanced before we give the new crown a final polish.

 

 

We work with a talented team of ceramic artists who will make sure the colour, shape and surface texture of the new crown is exactly as what we have designed and prescribed , to create a crown that is extremely natural looking.

FAQ

In order to fit the crown in between your teeth without altering your bite, the tooth to be crowned needs to be trimmed. This trimming is performed on all surfaces of the tooth, with more trimming done on the biting surface so that the new crown will be strong enough to bite on without cracking. 

 

This is especially critical for crowns made of porcelain (including zirconia).

 

Crowns made of metal (such as gold alloys) can be made thinner without compromising strength. Your dentist may advise a metal crown for a tooth with a short crown height (the part of the tooth visible above the gum) to maximise available tooth structure.

 

Teeth with large fillings or cracks that compromise structural integrity are usually crowned to prevent severe fractures that require extraction. A crown is a good way to prevent this from happening.
