Is a Crown Necessary After a Root Canal?

Root canal treatment can avoid extraction of a badly infected or otherwise severely damaged tooth. Placing a crown on the treated tooth is essential in many cases to ensure a long-lasting solution. A dental crown provides a protective shield after a root canal and helps restore the health and functionality of the tooth.

Attaching a crown is the final step in the root canal procedure, which is typically carried out under local anaesthetic and entails:

  • Creating an opening in the top of the tooth.
  • Removal of infected pulp at the centre of the tooth.
  • Root canal cleaning and disinfection.
  • Temporary filling if a further appointment is needed.
  • Applying the permanent, root canal filling – gutta-percha.
  • Applying a root canal sealant.
  • Placement of the dental crown.

Benefits of a Crown in Root Canal Treatment

A root canal removes a large part of a tooth’s structure, which often weakens the outer tooth. A crown minimises the risk of the tooth breaking, particularly with back teeth, which have to grind the food we eat.

By providing a protective casing for the entire tooth surface, a crown strengthens the root-filled tooth. It also enhances appearance by restoring natural shape, size and colour, and helps to protect the tooth from sensitivity.

Crowns can withstand strong bite force without risk of damage and can last up to 15 years. They’re custom made from various materials, including:

  • Pure porcelain.
  • Porcelain fused to metal.
  • Composite resin.
  • Metal allows such as gold or stainless steel.
  • Zirconia

Crowns for Root-Filled Front Teeth

Fillings rather than crowns are usually applied to front teeth after a root canal. However, you may need a crown for a root-filled front tooth if:

  • Significant tooth structure has been lost.
  • The tooth darkens as a result of the filling materials.

Use of Crowns with Dental Implants

Sometimes a tooth with dead nerves can’t be repaired, even by a root canal. A large cavity may have compromised too much of the tooth’s structure, for instance, or the tooth might have fractured below the gumline.

In cases like these, a dental implant provides an advanced tooth replacement option, and a crown plays an important role in this procedure as well as in root canal treatment.

The implant itself is a titanium rod that’s inserted into the socket of a missing tooth. It forms an artificial tooth root to provide the foundation for a crown.

Laser Root Canal Treatment and Costs

Advanced, pain-free laser dentistry is now available for root canal treatment before placement of a crown – a more affordable solution than replacing a tooth with a dental implant and crown.

Laser-assisted root canal therapy avoids the use of a drill. This streamlines the procedure, which usually takes just one appointment of about 30 minutes. A conventional root canal generally takes two or more visits to your dentist.

Laser root canal cost is determined by several factors, including the extent of decay and infection and the complexity of the procedure. Pricing at Laser Root Canal Treatment Sydney starts from $950, with interest-free payment plans to spread the cost over several months from $35 a week.
