A dental crown is a custom-made cap or covering that is placed over a damaged or weakened tooth to strengthen and protect it. It covers the entire visible portion of the tooth, extending from the gum line to the biting surface. Dental crowns are commonly used to restore teeth with significant decay, fractures, or those that have undergone root canal treatment.
The main purposes of a dental crown are to strengthen the tooth, protect it from further damage, and improve its appearance, shape, and alignment. By fully encasing the damaged tooth, a crown provides stability and durability, allowing for comfortable biting and chewing.
Dental crowns can be made from various materials, including porcelain, ceramic, metal alloys, or a combination of materials. The choice of material depends on factors such as the location of the tooth, the patient’s aesthetic preferences, and functional requirements.
You may need dental crowns if your teeth have significant decay, wear, fractures, developmental abnormalities, cracks, have undergone a root canal treatment, have been replaced with dental implants, or if you desire a smile makeover to address issues with color, shape, or alignment.
Stage 1: Consultation and Pre-Treatment
During the consultation, your dentist will examine your teeth, address your concerns, and may take X-rays or perform pulp tests. If a crown is recommended, your dentist will discuss the types of crowns available and decide on the most suitable option based on your condition and expectations.
Pre-treatment preparations may include placing a core filling material to restore large gaps in the tooth or gum contouring to ensure proper placement of the crown.
Stage 2: Crown Procedure
The crown procedure typically involves two appointments. The first visit involves preparing the tooth and taking measurements, while the second visit is for fitting the crown.
Crown Preparation The relevant tooth will be numbed with a local anesthetic. Superficial parts of the tooth are then removed to create space for the crown. An intraoral scan or mold is taken and sent to a dental laboratory to construct the crown. If a porcelain-fused-to-metal or full ceramic crown is chosen, you may select the color with your dentist. A temporary crown is placed to protect the prepared tooth while the final crown is being made.
Stage 3: Crown Fit
During the crown fit appointment, the temporary crown is removed, and the final permanent crown is tried on. It is checked for proper fit, bite harmony, and overall appearance. Minor adjustments may be made, and once finalized, the crown is sealed in place with cement. Local anesthesia is typically not needed for this step.
Stage 4: Post-Operative Care
After the crown is placed, you will be provided with instructions on how to care for it and maintain oral health. Well-made and well-maintained crowns can last for many years or even a lifetime with proper care. Regular dental check-ups and good oral hygiene practices are important to ensure the longevity of the crown.
