When Crowns are needed

Crowns are needed when the health of a tooth is in danger, usually in the following circumstances:

  • To protect a weak tooth or to hold together parts off a tooth
  • To restore a broken or severely worn tooth
  • To cover a large filling where there is too little tooth material left to sustain the filling
  • To hold a dental bridge in place
  • To cover misshaped or severely stained teeth
  • To cover dental implants for cosmetic reasons

What You Can Expect at Dentist@Health


The dentist may take X-rays to check the roots of the tooth and surrounding bone in cases of severe decay or risk of infection or injury to the tooth pulp

The dentist may perform root canal treatment first

Your dentist will anaesthetize the tooth and surrounding area

The tooth will then be filed down to make space for the crown

Impressions are made of the tooth and opposing tooth to ensure that the crown does not affect your bite

The impressions are sent to the dental laboratory where the crown will be manufactured

Your dentist will make a temporary crown while you wait for the laboratory

At a return visit, the tooth is anaesthetized and the crown is cemented into place

Caring for your Crowns

The dentist will explain how the temporary crown needs to be treated.

A permanent crown should be maintained with proper dental care, the same as your other teeth.

Possible difficulties with crowns may include:
  • Discomfort or sensitivity when the anaesthesia wears off
  • The crown may be sensitive to heat and cold if the nerve remains
  • Pain when biting which means the crown is too high. Your dentist can fix this problem easily.
  • Chipped crowns. Depending on the severity it may require repairs or a new crown
  • Loose crowns sometimes occur when the cement washes away from underneath the crown. Call dentist@health.
  • A crown may fall out for a number of reasons. Your dentist will attend to that.
  • A dark line may occur next to the gum depending on the material used for the crown. It is no problem but see your dentist if it is aesthetically unacceptable to you.
Crowns last up to 10 years, depending on your oral hygiene, and whether you grind or clench your teeth, chew ice, bite fingernails or open packaging with it.
