When is a Dental Crown Necessary (Best Dentist Weighs In)

A dental crown is necessary when a tooth is severely damaged or weakened, making it unsuitable for fillings or other treatments. Crowns are recommended after root canal therapy, for cracked or worn teeth, and in large cavities. They provide essential reinforcement to maintain tooth integrity and functionality.

Dental crowns also serve cosmetic purposes, enhancing the appearance of discolored, misshapen, or small teeth. They anchor dental bridges and cap dental implants, offering natural-looking replacements. Dentists assess your needs to determine if a crown is the best solution for long-term dental health and aesthetics. Regular check-ups help decide the appropriate treatment.

What are the common signs and symptoms indicate the need for a dental crown?

Common signs and symptoms indicating the need for a dental crown include:

  • Severe Tooth Decay: Extensive cavities that cannot be effectively treated with a filling may require a crown to restore the tooth’s structure and function.
  • Cracked or Fractured Teeth: Teeth that are cracked or fractured, especially those with large breaks, need crowns to prevent further damage and restore strength.
  • After Root Canal Therapy: Teeth that have undergone root canal therapy are often weakened and require crowns to protect them from future damage and breakage.
  • Large Fillings: Teeth with large fillings that compromise their structural integrity might need crowns to provide additional support.
  • Worn-Down Teeth: Teeth significantly worn down from grinding (bruxism) or erosion may benefit from crowns to restore their shape and function.
  • Discolored or Misshapen Teeth: Crowns can improve the appearance of severely discolored or misshapen teeth, enhancing your smile aesthetically.
  • Broken Cusps: When a tooth’s cusps (the pointed parts) are broken, a crown can help restore their normal shape and function.
  • Tooth Sensitivity or Pain: Persistent sensitivity or pain, especially when biting down, can indicate damage or structural issues that a crown can address.
  • Support for Dental Bridges: Crowns anchor dental bridges, providing stability and support for the replacement teeth.

If you experience any of these signs or symptoms, it’s important to consult with your dentist. They can assess your condition and determine if a dental crown is the appropriate treatment.

How does getting a dental crown typically work, and what should patients expect?

Getting a dental crown typically involves several steps over two dental visits. Here’s what patients can expect:

First Visit: Examination and Preparation

  • Initial Consultation: The dentist examines the tooth and takes X-rays to assess its health and the surrounding bone structure. A significant deterioration or infection risk may require a root canal first.
  • Tooth Preparation: The dentist numbs the area around the tooth and then reshapes it to make room for the crown. This may involve removing a portion of the outer tooth structure.
  • Impressions: After reshaping, the dentist takes an imprint of the prepared tooth and surrounding teeth. The impression is used to make a bespoke crown fit perfectly.
  • Temporary Crown: The prepared tooth is protected by a temporary crown while the permanent crown is made. This temporary crown is usually made of acrylic and is cemented in place.

Second Visit: Crown Placement

  • Temporary Crown Removal: The dentist removes the temporary crown and cleans the prepared tooth.
  • Fitting the Permanent Crown: The permanent crown, customized to match your teeth’s color and form, is placed over the prepared tooth. The dentist checks the fit and bite and makes any necessary adjustments.
  • Cementing the Crown: The crown is permanently cemented in place once the fit is perfect. The dentist ensures that the crown sits correctly and that your bite is comfortable.

What to Expect

  • Slight Discomfort: Some patients may experience mild discomfort or sensitivity after the tooth preparation and crown placement. This is normal and usually subsides after a few days.
  • Proper Care: Maintain good oral hygiene by brushing twice daily, flossing daily, and attending regular dental check-ups. Avoid biting hard items to protect the crown.
  • Longevity: With proper care, dental crowns can last 10-15 years or longer, providing a durable and aesthetically pleasing solution for damaged teeth.

Patients should follow their dentist’s instructions for maintenance to guarantee lifetime and success in their dental crown.

What are the different types of dental crowns available, and how does a dentist determine which is best for a patient?

Several types of dental crowns are available, each with its advantages and disadvantages. The choice of crown depends on tooth location, patient bite, aesthetic concerns, and budget. Here are the main types of dental crowns:

  1. Porcelain-Fused-to-Metal (PFM) Crowns
    • Advantages: Strong and durable; good aesthetics as they can be color-matched to natural teeth.
    • Disadvantages: The metal underlayer can sometimes show as a dark line at the gumline; it may wear down opposing teeth more than other types.
    • Best for: Both front and back teeth.
  2. All-Porcelain or All-Ceramic Crowns
    • Advantages: Excellent aesthetics; no metal, so there’s no dark line at the gumline; biocompatible.
    • Disadvantages: Less durable than metal or PFM crowns; more prone to chipping or breaking.
    • Best for: Front teeth or areas where aesthetics are a high priority.
  3. Metal Crowns (Gold or base-metal alloys)
    • Advantages: Extremely durable and strong; requires less removal of tooth structure; gentle on opposing teeth.
    • Disadvantages: Poor aesthetics due to metallic color.
    • Best for: Back molars where strength and durability are more important than appearance.
  4. Zirconia Crowns
    • Advantages: Very strong and durable; excellent aesthetics; can be color-matched; biocompatible.
    • Disadvantages: It can be more expensive, harder than other types, and potentially wear down opposing teeth.
    • Best for Both front and back teeth, especially in areas requiring strong, durable solutions.
  5. E-Max Crowns (Lithium Disilicate)
    • Advantages: High strength and excellent aesthetics; minimal tooth preparation needed.
    • Disadvantages: It can be more expensive than other types.
    • Best for: Both front and back teeth, particularly when aesthetics and strength are important.

How a Dentist Determines the Best Crown for a Patient

  • Location of the Tooth: All ceramic or porcelain-fused-to-metal crowns are often recommended for front teeth, where aesthetics are crucial. Metal or zirconia crowns may be preferred for back teeth where strength and durability are more important.
  • Patient’s Bite and Function: The dentist will consider how the patient’s teeth come together when biting and chewing. Stronger materials like metal or zirconia may be recommended for patients with heavy biting forces.
  • Aesthetic Concerns: All-ceramic or porcelain-fused-to-metal crowns are usually chosen for patients who prioritize a natural look.
  • Allergies and Sensitivities: If a patient has allergies to certain metals, metal-free options like all-ceramic or zirconia crowns are considered.
  • Tooth Structure: The remaining natural tooth structure can influence the choice. For teeth with significant damage or wear, crowns that require less tooth reduction, like metal crowns, might be preferred.
  • Cost: The patient’s budget can also influence the decision. Some materials, like all-ceramic or zirconia, can be more expensive than others.

By evaluating these factors, the dentist can recommend the most appropriate type of crown to meet the patient’s needs, ensuring both functionality and aesthetics are optimized.

Are there any potential risks or complications associated with getting a dental crown, and how can they be prevented?

Getting a dental crown is generally safe, but potential risks include tooth sensitivity, discomfort, loosening, decay, and allergic reactions to metal crowns. Sensitivity can arise if the tooth’s nerve is irritated, and a poorly fitted crown can lead to discomfort. A crown might also become loose or fall off if the cement weakens, and the underlying tooth can still decay if oral hygiene is neglected.

Preventing these complications involves selecting an experienced dentist for a proper fit and maintaining excellent oral hygiene through regular brushing, flossing, and check-ups. 

Avoiding hard foods can prevent damage, and opting for metal-free crowns like all-ceramic or zirconia can prevent allergic reactions. These measures help ensure a successful and long-lasting dental crown.
