What Are Teeth Crowns
What Are Teeth Crowns?
Dental crowns are protective coverings that fit over damaged teeth. These custom-made restorations restore tooth shape, size, strength, and appearance. Crowns completely encase the visible portion of the tooth above the gum line, providing structural support and protection.
Common Reasons for Dental Crowns
Dentists recommend crowns for various dental situations. They protect weak teeth from breaking or restore already broken teeth. Crowns cover teeth with large fillings when little natural tooth remains. They also support dental bridges and cover dental implants.
Other common uses include covering discolored or misshapen teeth and protecting teeth after root canal treatment. Crowns provide both functional and aesthetic benefits, helping maintain proper dental alignment and bite function.
Types of Dental Crown Materials
Several materials are available for dental crowns, each with distinct advantages. Porcelain crowns offer excellent natural appearance and blend well with surrounding teeth. Ceramic crowns provide similar aesthetic benefits with good durability.
Metal crowns, including gold alloy and base-metal alloys, offer superior strength and longevity. Porcelain-fused-to-metal crowns combine metal strength with porcelain aesthetics. Resin crowns are more affordable but wear down faster than other types.
The Crown Placement Process
The dental crown procedure typically requires two appointments. During the first visit, the dentist prepares the tooth by removing decay and shaping the surface. An impression of the prepared tooth creates the custom crown.
- Tooth examination and preparation
- Tooth reshaping and reduction
- Impression taking
- Temporary crown placement
- Permanent crown fabrication
- Final crown cementation
Caring for Dental Crowns
Proper maintenance extends crown longevity and protects underlying teeth. Regular brushing and flossing prevent decay at the crown margins. Avoid chewing hard foods or objects that could damage the crown.
Regular dental checkups allow professionals to monitor crown condition and underlying tooth health. With proper care, dental crowns typically last between five and fifteen years, depending on material and oral hygiene practices.
Benefits of Dental Crowns
Dental crowns offer multiple advantages for oral health. They restore chewing function and prevent further damage to compromised teeth. Crowns improve smile appearance by covering dental imperfections and matching natural tooth color.
They maintain proper tooth alignment and prevent shifting of adjacent teeth. Crowns also protect sensitive teeth after procedures like root canals, reducing discomfort and sensitivity to temperature changes.
