Temporary crowns explained

A temporary crown is a short-term dental restoration used to protect a tooth or dental implant while a permanent crown is being fabricated. Dentists typically place temporary crowns after procedures like root canals, dental implant surgery, or preparation for a traditional crown. These restorations are vital for maintaining oral function, appearance, and preventing further damage or discomfort during the waiting period before the permanent crown is ready.

Purpose of a Temporary Crown

Temporary crowns serve several key purposes:

1. Protection of the Tooth: After a tooth has been shaped and prepared for a crown, it becomes more vulnerable to sensitivity and damage. A temporary crown acts as a protective shield, covering the exposed areas of the tooth.

2. Maintaining Tooth Alignment: Without a crown in place, neighboring teeth might shift, affecting the fit of the final crown. The temporary crown ensures the space and alignment are preserved.

3. Functional Support: Temporary crowns enable patients to chew and speak normally while waiting for the permanent restoration.

4. Aesthetic Function: Especially for front teeth, temporary crowns maintain a natural appearance and prevent cosmetic concerns during the interim period.

Materials Used in Temporary Crowns

Temporary crowns are made from less durable materials than permanent ones. The most common materials include:

• Acrylic Resin: Lightweight and easy to manipulate, commonly used for short-term coverage.

• Composite Resin: Offers a slightly better appearance and durability.

• Aluminum or Stainless Steel: Often used for molars, particularly in pediatric or emergency dentistry.

These materials are chosen for their affordability and ease of customization, knowing they are not intended for long-term use.

Placement Procedure

The process of getting a temporary crown typically involves the following steps:

1. Tooth Preparation: The dentist removes decay or old fillings and reshapes the tooth to accommodate the crown.

2. Impression or Digital Scan: An impression or scan of the prepared tooth is taken and sent to a dental lab to create the permanent crown.

3. Fabrication of Temporary Crown: The dentist either preselects or fabricates a temporary crown chairside, shaping it to fit the prepared tooth.

4. Cementation: The temporary crown is attached using a weak dental cement, allowing for easy removal later.

The entire process is generally quick and performed during a single visit, making it convenient for the patient.

Duration and Care

Temporary crowns are usually worn for 2 to 3 weeks, but this can vary depending on the complexity of the permanent crown being made or any complications in the treatment plan. Some dental procedures may require a longer wear time.

To care for a temporary crown, patients should:

• Avoid sticky or hard foods: These can dislodge or crack the crown.

• Chew on the opposite side: This minimizes stress on the temporary crown.

• Maintain good oral hygiene: Brush gently around the crown and floss carefully to avoid dislodging it.

• Avoid using toothpicks or dental floss aggressively: Doing so might loosen or remove the crown prematurely.

Potential Issues and Solutions

While temporary crowns are generally safe and effective, they can occasionally present issues:

1. Crown Falls Off: This is one of the most common problems. If this happens, try to keep the crown and contact your dentist immediately. In some cases, it can be re-cemented.

2. Sensitivity: Since the temporary material doesn’t seal the tooth completely, you might experience sensitivity to hot, cold, or pressure.

3. Discoloration: Temporary crowns can stain more easily due to the porous nature of the materials used.

4. Discomfort or Improper Fit: If the crown feels too high or causes irritation to your gums, it’s important to have it adjusted to avoid further complications.

Transition to a Permanent Crown

When the permanent crown is ready, usually within two to three weeks, you will return to the dentist for placement. The steps generally include:

• Removal of Temporary Crown: The dentist carefully removes the temporary crown, cleans the tooth surface, and ensures no cement or debris remains.

• Fitting the Permanent Crown: The new crown is placed and checked for fit, color match, and bite alignment.

• Cementation: Once everything looks good, the dentist uses a strong adhesive to secure the permanent crown in place.

The final crown is typically made of materials like porcelain, ceramic, metal alloys, or zirconia and is designed to last many years with proper care.

When Are Temporary Crowns Especially Important?

There are several situations where temporary crowns are indispensable:

• After Root Canal Treatment: Teeth that have undergone a root canal are structurally weaker and need protection until the final crown is placed.

• Implant Restorations: Implants often need time to integrate with the bone before placing the permanent crown. A temporary crown can shape the gum tissue and provide aesthetics.

• Full Mouth Reconstructions: In complex restorative cases, temporary crowns allow for a preview of the final results, enabling both patient and dentist to make necessary adjustments.

Temporary Crowns in Cosmetic Dentistry

In cosmetic procedures, temporary crowns are not only used for protection but also to simulate the final outcome. This “trial smile” phase gives patients a chance to evaluate the size, shape, and color of the restorations before committing to the final version. Any desired changes can be communicated to the dental lab before the permanent crowns are made.

Cost and Insurance Considerations

Temporary crowns are generally included in the overall cost of a dental crown procedure. Insurance policies typically cover the cost of both temporary and permanent crowns when deemed medically necessary. However, cosmetic crowns may not always be covered. It’s best to consult with your dental provider for a breakdown of fees and insurance coverage.

Conclusion

Temporary crowns play a vital role in modern dentistry by providing protection, aesthetics, and functionality between dental appointments. Though not meant to last long, they ensure patient comfort and treatment success by safeguarding vulnerable teeth and preserving oral health during the transitional period. With proper care and follow-up, they serve as an essential bridge to a permanent and durable dental restoration.
