Dental Crowns: Overview


A dental crown, also known as a tooth cap, is a custom-made covering placed over a tooth to restore its shape, size, and strength, or to enhance its appearance. Crowns are often used when a tooth is damaged or weakened, covering and protecting it from further decay or breakage. They fit snugly over the visible portion of the tooth above the gum line, effectively providing a new, durable exterior. Made from various materials such as porcelain, ceramic, metal, or composite resin, dental crowns are designed to mimic the appearance of natural teeth, offering both functional and aesthetic benefits.


The process of receiving a dental crown typically involves preparing the tooth, taking impressions, and placing a temporary crown until the permanent one is ready. Dental crowns are a versatile dental solution that can address various dental issues, from strengthening a tooth weakened by decay to serving as a part of a dental implant.


When Would You Need a Teeth Cap?

A dental crown may be recommended in several situations where other restorative treatments might not suffice. Here are common reasons you might need a dental crown:


  1. Large Cavity or Extensive Decay: If a tooth has a significant cavity that cannot be effectively restored with a filling, a crown can protect it from further damage.

  2. Tooth Fracture or Crack: A crown can provide the necessary stability and protection when a tooth has a crack or fracture, especially if it extends below the gum line.

  3. Root Canal Treatment: A tooth becomes more fragile and susceptible to breakage after a root canal. A crown helps protect and restore the tooth’s structure.

  4. Worn Teeth: Teeth worn down over time due to grinding (bruxism) or acid erosion may require crowns to restore their function and appearance.

  5. Dental Implant Restoration: Crowns are often used to cover dental implants, giving them a natural appearance and allowing them to function like real teeth.

  6. Cosmetic Enhancement: Crowns can also be used for aesthetic purposes, such as covering a discolored or poorly shaped tooth.


Dental crowns are highly effective in preserving the natural tooth structure while ensuring a lasting and resilient solution for various dental issues.


Kinds of Dental Crowns

Several types of dental crowns are available, each offering unique properties suited for different dental needs:


  1. Porcelain Crowns: These crowns are ideal for front teeth due to their natural appearance and translucency, which mimics real enamel. However, they may be less durable than other types.

  2. Ceramic Crowns: Similar to porcelain crowns, ceramic crowns offer a natural look and are highly resistant to staining. They are suitable for both front and back teeth.

  3. Metal Crowns: Made from gold or other metal alloys, metal crowns are known for their strength and durability. They can withstand high biting forces, making them ideal for molars.

  4. Porcelain-Fused-to-Metal (PFM) Crowns: These crowns combine the strength of metal with the aesthetic appeal of porcelain. The metal provides durability, while the porcelain coating offers a more natural look.

  5. Resin Crowns: While these crowns are less expensive, they are more prone to wear and may not last as long as other materials.

  6. Zirconia Crowns: Zirconia is an exceptionally strong and durable material, ideal for individuals who need extra strength and resistance to breakage.


Each type of crown has its own set of benefits and drawbacks, and the choice often depends on the location of the tooth, your personal preferences, and the recommendation of your dentist.


What Happens During a Dental Crown Procedure?

Getting a dental crown typically involves two appointments with the dentist:


  1. First Visit: Preparation and Temporary Crown Placement

    • The dentist will begin by examining and preparing the tooth, which may involve filing it down to create room for the crown.

    • Next, an impression of the prepared tooth is taken to create a custom-fitted crown.

    • A temporary crown is placed to protect the tooth while the permanent crown is being made, which can take a couple of weeks.


  2. Second Visit: Fitting and Placement

    • Once the permanent crown is ready, the dentist will remove the temporary crown and check the fit and color of the new crown.

    • Adjustments may be made to ensure comfort and accuracy.

    • Finally, the crown is cemented into place, completing the restoration.


The procedure is straightforward, and with proper care, a dental crown can last for many years.


Advantages of Dental Crowns

Dental crowns offer numerous benefits, making them one of the most popular restorative dental treatments. Here are some key advantages:


  1. Enhanced Aesthetics: Crowns can restore the natural appearance of damaged teeth, making them look uniform and visually appealing.

  2. Protection for Damaged Teeth: A crown strengthens and protects weak teeth, reducing the risk of further breakage or decay.

  3. Restoration of Functionality: Crowns allow patients to chew and speak comfortably, even with previously compromised teeth.

  4. Durability and Longevity: Crowns are designed to last, with many lasting up to 10-15 years or more with proper care.

  5. Versatility: Crowns can be used for a wide range of purposes, from strengthening decayed teeth to covering implants or correcting aesthetic issues.

  6. Improved Oral Health: By covering a damaged tooth, crowns help prevent further dental problems, promoting overall oral health.


Are Teeth Caps Permanent?

Dental crowns are a long-term dental solution, but they are not entirely permanent. With good care, crowns can last anywhere from 5 to 15 years or longer. Factors such as the material used, oral hygiene habits, and the location of the crown in the mouth all play a role in determining the lifespan of a crown. For instance, crowns on molars that experience heavy chewing forces may wear out sooner than crowns on front teeth.

Maintaining regular dental visits, practicing good oral hygiene, and avoiding habits like grinding or clenching can help prolong the life of your dental crowns.


When Should You Call a Dentist?

If you experience any issues with your dental crown or have concerns about your oral health, it’s essential to contact your dentist. Here are some situations where a dental visit may be necessary:


  • Pain or Sensitivity: If you experience prolonged sensitivity or pain in a crowned tooth, it may be a sign of an underlying issue, such as decay or an ill-fitting crown.

  • Damage or Wear: Chipping, cracking, or wearing down of the crown should be addressed to prevent further damage.

  • Looseness or Dislodgement: If the crown feels loose or falls off, it’s crucial to see a dentist as soon as possible to avoid damage to the underlying tooth.

  • Gum Irritation or Inflammation: Swelling or redness around the crowned tooth could indicate an infection or other dental problem that requires treatment.
