Crowns

Treatment Time
2 office visits; 1-4 hours each for up to 4 teeth (more time needed for more extensive treatment).

Maintenance

• Avoid biting down on hard foods and ice
• Get yearly fluoride treatments
• Brush and floss daily

Results
The best method to improve tooth shapes is to fill spaces.

Treatment Longevity
5-15 years (directly related to fractures, problems with tissues, and decay).

Advantages

• Can be shaped to esthetically fill gaps
• Teeth can be lightened to any shade
• Some realignment or straightening of teeth is possible
• Should last about twice as long as the bonding
• Gum tissue tolerates porcelain well
• Colour change is possible

Disadvantages

• Can fracture
• Requires an anaesthetic
• Tooth form is altered (most of the tooth enamel is removed)
• May need to be replaced after 5-15 years
• More expensive than bonding
