Dental Crowns or Caps are permanent dental restorations that can protect weakened teeth by reinforcing them, modify the size of a tooth to the standard size when it is undersized or exhibit wear, and enhance the aesthetic of teeth that are poorly structured or discoloured.
Crowns can be put on either natural teeth or implants. Dental Crowns (also known as Dental Caps or Tooth Caps) are used to restore a tooth's natural form and strength, or to enhance its aesthetics.
We should consider dental crowns only if we have ruled out other treatment options that can provide the identical end results. If unsure, seek advice from a qualified dental specialist.
Dental crowns often need the removal of significant tooth material to be correctly placed on a natural tooth.
A dental crown may be required in the following circumstances:
To prevent a weaker tooth from fracturing (due to decay, for example) and bind fragmented tooth fragments together, to repair a tooth that has already fractured or has been significantly worn down, and to make cosmetic changes.
It encompasses and reinforces a tooth with a large restoration as the minimal tooth structure remains.
Secures a dental prosthesis in place, conceals badly deformed or discolored teeth, and is placed on a dental implant.

A dental crown may help you enhance your oral health while also concealing various aesthetic defects in your teeth.
As with every procedure, dental crowns have certain downsides. The dentist must first permanently restructure and reduce the afflicted teeth. Even though the materials used to build crowns are robust and resilient, they are susceptible to cracking with time.
Some minor cracks can be fixed, but if your restoration has a lot of chips or cracks, the dentist might need to replace it with a new crown.
In rare cases where the dental cement used to secure a crown somehow weakens or dissolves, microorganisms may from underneath the crown.
Inadequately fitting crowns loosen and even fall off.
Lastly, after having a dental crown, some patients report increased sensitivity to cold and hot temperatures; however, this issue is often resolved by using toothpaste formulated for sensitive teeth.
Preparing a tooth for a crown typically requires at least two dental visits. The first dental appointment's objective is to analyze, prepare, and take an impression of the tooth receiving the crown so that the crown may be fabricated.A temporary crown is frequently applied during this visit to protect the tooth.
In the second session, the temporary crown is removed. A permanent crown (prepared in a dental laboratory) is cemented into place and the treatment is complete.
First Appointment: Investigation, Tooth Reshaping, Impression, and Provisional Crown
At the first dental session, an X-ray of the tooth and jawbone is routinely taken to search for signs of caries and other variables that may elevate the infection risk or pulpal trauma. Before inserting crown on a tooth, a root canal treatment may be necessary.
To make place for the crown, the tooth must be molded; the amount of reshaping required depends on the kind of crown selected. Metal-based crowns are often thinner and need less tooth structure removal than porcelain crowns.
As essential for crown preparation, a tooth's chewing and proximal surfaces must be decreased. On top of that, cavities must be restored during this treatment. There would not be sufficient tooth structure to place a crown on some persons with significant cavities or tooth damage. Before crown can be placed, the tooth's structure may need to be restored with a restorative material.
After the tooth has been suitably prepared, an impression of the tooth is taken so that the crown may be produced to fit perfectly. An impression is required for the opposite jaw tooth to contact the crown whenever the patient bites so that the crown fits appropriately on the opposite side of the mouth where it is cemented.
Dental impressions are often made with a paste or putty material that maintains the structure of the tooth. It is applied to the area to be replicated and then removed, leaving the structure of the relevant tooth on its surface.
At this stage, it is essential to record dental characteristics that will influence the manufacturing of the crown, like the tooth's original color and shape. The crown's hue should match closely with that of the tooth and adjacent teeth to look natural after it has been inserted into the mouth.
In most cases, a temporary crown is cemented onto the tooth for protection until the permanent crown is manufactured and ready to be cemented into place. The permanent crown will replace the temporary crown at the following dental appointment.
Second Visit: Permanent Crown Positioning
Meanwhile, impression of the teeth is sent to a dental technician/laboratory to manufacture the crown in the appropriate shape. This may take up to three weeks, so more than one dentist appointment is required to place a permanent crown successfully.
Once a dental technician or laboratory has fabricated the crown and is ready to cement on the tooth, remove the provisional crown if it has been inserted.
Before the permanent crown is cemented, it is critical to confirm that it was appropriately fabricated, with the fit and color matching the original and surrounding teeth.
A topical anesthesia is provided to sedate the region during the crown-fitting procedure. Utilizing dental cement, the crown is cemented to the tooth.
If there are difficulties with the patient's bite where the crown contacts the opposing tooth, it may be essential to make minor modifications to the crown's form.
Same-Day Crowns Placement Procedure:
In certain cases, crowns may be fabricated and inserted in the dentist's office on the same day without sending impressions to a dental laboratory.
Instead of generating a dental impression, a wand-like scanning instrument is used to capture photographs of the teeth which are then transferred into a computer program that produces a 3D model of the tooth.
A ceramic crown may be fabricated using this computer model in a day. This computer-assisted design and production of dental crowns (CAD/CAM), may be completed in fifteen minutes or less, enabling the crown to be fitted swiftly.
The tooth is numbed with a topical anesthesia before the crown procedure commences. If the tooth is fractured or has had root canal treatment, it will require a buildup, a restoration that provides sufficient tooth material for the crown to attach.
The tooth is reduced to give space for the crown, and a putty material or digital scanner is used for an impression of the prepared tooth. The dentist will then utilize a shade guide or photographs of the patient's teeth to enable the lab technician to construct crowns that complement the remaining patient's teeth.
A temporary crown is fabricated from resin or acrylic material utilizing the original tooth's impression or stent. This provisional crown is bonded using temporary cement to be readily retrieved when a permanent crown becomes available.
Patients return for 2nd appointment to the dentist a few weeks after the placement of a temporary crown for crown removal. The permanent crown is cemented onto the tooth and checked for correct fit, bite, and smooth edges.
After any necessary adjustments, permanent dental cement or dental glue is used to cement the crown.
For a multi-day procedure:
The impression of the tooth and surrounding soft tissues will be taken by the dentist and sent to the lab, where the crown will be made to fit the tooth perfectly
Provisional crown insertion:
Your dentist will next place a temporary crown on your tooth. This cover is designed to fit on your tooth, but it is not meant to stay in place for long. It is intended to safeguard your susceptible tooth till your dentist places the permanent crown.
You may return home after receiving the temporary crown. Maintaining your temporary crown should be done with caution since it is not meant to last long.
Return to the dentist office:
After two weeks, return to the clinic to have the temporary crown removed.
Final crown placement:
Your dentist will select a dental cement suitable for the crown type and its position; these variables can impact the level of stress the crown can withstand. According to studies, resin cement is the best approach for zirconia crowns.
The dentist will apply an even cement coating to the crown's core. The dentist will then gently attach the crown to the tooth. Any excess cement will be removed after it has been appropriately fitted.
Crown preparation for same-day treatment:
If your dentist provides same-day crowns, you will only need to visit the office once to have your new crown fabricated and fitted. You must only wait until the crown is constructed.
CEREC crowns are a kind of crown often utilized in same-day procedures that are constructed of very durable ceramic. This method is intended to reduce the time required for crown fabrication and installation.
It scans the teeth and creates a three-dimensional model that controls crown fabrication in the dentist's office using computer-assisted design (CAD) and computer-assisted manufacturing (CAM). Since its inception more than four decades ago, the method has developed and been enhanced.
Explaining how the method differs from the multi-day procedure: Scanning
If you seek a same-day crown, some digital scans of your jaw will be taken, focusing on the specific tooth in need of a crown, and also the surrounding gum area. Your dentist will transmit the precise dimensions and attributes of the digital images to the crown fabrication equipment.
Your crown model will be developed and designed using CAD/CAM software. The crown will then be molded from a ceramic block using a milling process, depending on the model.
Typically, the equipment will first remove excess ceramic, then cut and tune the piece until it fits properly in your mouth.
Installing the crown:
Your dentist will select a suitable dental cement for the crown's placement once it has been prepared. Then, you will need to open your mouth again so they may gently install the crown on your tooth.
For a same-day crown procedure and insertion, you may opt for local anesthesia. After the local anesthesia has worn off, you should be able to move freely.
It is essential to take exceptional care of your crown after getting it because it prevents your tooth from deterioration. It is normal to have some pain as your injured tooth adjusts and heals as your mouth changes to the repair.
Generally, ibuprofen or other over-the-counter pain relievers may alleviate this discomfort and lessen the associated swelling. Talk to your dentist post-operation to confirm which drugs are best for you.
We understand you may want to change your plans due to the coronavirus (COVID-19) and its health implications.
Discomfort or sensitivity: Your newly crowned teeth may be sensitive shortly after the procedure when the anesthesia wears off.

What Types of Crowns Are Available?
Permanent crowns may be manufactured from all metal, porcelain-fused-to-metal, all resin and all ceramic.
Crowns may be made of gold alloy, other alloys (such as palladium), or base-metal alloy (nickel or chromium).
Metal crowns need less tooth material reduction than most other crown types and have less opposing tooth wear. They are resistant to biting and chewing pressures, are rarely damaged or fragmented, and are projected to last the longest. The primary disadvantage is the shiny hue. Metal crowns are an excellent solution for molars that are not visible.
Porcelain-fused-to-metal crowns can be shade-matched to your surrounding teeth, they resemble natural teeth the most, after all-ceramic crowns. However, compared to metal or resin crowns, this crown type causes higher wear on the adjacent teeth. The porcelain piece of the crown might potentially chip or fall off.
The metal beneath the porcelain crown might sometimes show a dark line, particularly at the gingival margin and even more if the gum recedes. These crowns may be used on either the front or back teeth.
Dental crowns made of all resin are less costly than other crowns. They do, however, deteriorate with time and are much more prone to fracture than porcelain-fused-to-metal crowns.
All-ceramic/all-porcelain dental crowns have the most natural-looking color match of any crown material and may be more suitable for those with metal allergies. They are, however, not as robust as porcelain-fused-to-metal crowns and wear opposing teeth down somewhat more than metal or resin crowns. Crowns made of all ceramic are beneficial for front teeth.
Temporary versus permanent
In the dentist's office, provisional crowns are fabricated and are made of acrylic or stainless steel, whereas permanent crowns are fabricated in a dental laboratory.
What is the lifespan of dental crowns?
Dental crowns typically survive from 5 and 15 years. The longevity of a crown is determined by the extend of "wear and tear" it endures, how you practice proper oral hygiene, and other parafunctional habits such as grinding or clenching of teeth, ice chewing, nail-biting and using teeth to tear apart plastic packaging.
Does a crowned tooth require special care?
While a tooth with a crown does not need particular care, but underlying tooth is still susceptible to caries and gingivitis. Maintain good oral hygiene by brushing your teeth at least twice per day and flossing once per day, focusing on the area where the gum touches the crown.
