A dental crown is an outer shell placed as a covering to a damaged tooth to restore its shape, strength, and function. A dental crown is recommended for teeth that are severely decayed, broken, weakened or cracked. They look identical to natural teeth and are made from porcelain, metal, gold or a combination of the three.
Dental crowns can also be placed on teeth where fillings repeatedly dislodge as a more definitive form of treatment. They are also routinely placed on back teeth that have been root canal treated as they are brittle and susceptible to cracks.
Dental crowns are generally needed to reinforce and give strength to teeth. These instances include:
Examination and assessment of the tooth structure and colour.
In order to assess if a tooth is suitable for a crown, sometimes the existing filling may have to be removed and replaced with a new filling. X-rays will have to be taken to aid in the overall assessment. Local anaesthetic (an injection) will have to be used if the tooth is not root canal treated. Some numbing cream will be placed on your gums before you have the injection. You will feel numb which is a sensation of feeling ‘fat’ in that area.
First, the tooth is reshaped to specific dimensions. Then, an impression of your teeth will be taken by biting onto a material that feels similar to Playdough for a few minutes. The dentist will construct a temporary crown for you. This will be placed on your tooth with temporary cement. The impression will be sent to a dental laboratory where the dental crown is fabricated. Some sensitivity may be experienced if the tooth is not root canal treated. As the crown is only temporary, extra care must be taken during eating, brushing and flossing.
Finally, the temporary crown will be removed. The tooth is cleaned, and the dental crown will be fitted in and checked. Some minor adjustments of the bite may be necessary. A small X-ray may also be taken. If satisfactory, this crown will be cemented in place with an extremely strong cement.
