You may need a dental crown if you have a badly stained or discoloured tooth, if you have a chipped or cracked tooth, for other cosmetic reasons, if your tooth had root canal therapy, if your tooth has a very large filling, or when your tooth has a combination of a large filling and root canal therapy.

Getting a dental crown involves the following procedures: visiting the dentist for a dental examination, tooth preparation, taking the x-ray or impression of the mouth, placing the temporary crown while the permanent crown is been made, placing and cementing the permanent crown.

This article addresses all the basic steps involved in getting a dental crown procedure. To start with, you may want to know how long it takes to get the permanent dental crown on your tooth.

Normally, a dental crown procedure requires two separate dental visits to prepare your tooth and to make and place the permanent dental crown.

Initial Appointment

You can just conclude on your own that you need a dental crown procedure. You need to make a prior consultation with your dentist who will examine your dental condition and ascertain that you need a dental crown. The initial appointment typically involves checking your dental health record and conditions.

Numbing the Tooth

Numbing the affected tooth is the first step involved in the dental crown procedure.  This involves using a general/local anesthetic to numb the affected tooth and its surrounding tissues. This is because the dental tool may come very close to the gums.

Taking the Preliminary Impressions and Shade

After numbing, accurate models of both your mandibular and maxillary arches are required to fabricate your dental crown in the dental lab. This is necessary to create a perfect bespoke dental crown for you. In the case of porcelain fused to metal crown or full ceramic, your dentist would need to also take the exact shade of the affected tooth and neighboring teeth before the tooth preparation begins.

Alginate Impressions

This impression is usually used to make the temporary crown you would wear while your permanent crown is being fabricated in the dental lab. Once the impression has been taken, your dentist would use a shade guide to take the exact color of the affected tooth. But if you opted for a gold dental crown, there would be no need to record the shade of the tooth.

Tooth Preparation

This is one of the major parts of the dental crown procedure. The dental crown is just like the natural tooth but with a hollow space inside of it like a dental cap and must be worn over the affected tooth. Hence, the affected tooth must be adjusted and shaped properly for the permanent crown to fit properly. Part of the affected tooth needs to be filed down or reduced to allow the dental crown to sit on top perfectly and securely. This calls for tooth preparation.

After numbing the teeth, your dentist would place a rubber dam over the affected teeth to trap saliva, water, tooth structure, and old filling materials from falling into your mouth.

During tooth preparation, a precise amount of the affected tooth and filling material is removed for the dental crown. Also, any discovered tooth decay is removed and a composite core may be placed on the tooth.

Once the decay is removed and the core is complete, sufficient part of the tooth and filling is removed. This is the most crucial step and the step that takes the most time to be completed.

Taking the Final Impression

After the tooth preparation, taking another impression is necessary because even the slightest mistake in dental crown mars the whole process and the best way to avoid an ill-fitting crown is to avoid any flaw in the impression.

Your dentist takes the impression by using the polyvinyl siloxane impression material. The material is filled into the impression tray and the patient is asked to bite down. The dentist may take multiple impressions so as to obtain a very accurate impression.

Placing the Temporary Dental Crown

While the permanent crown is being made in the dental lab, the dentist would place a temporary crown over the prepared tooth. Placing the temporary crown is not just for a cosmetic necessity, it has a number of benefits. The temporary crown is mostly made from an acrylic resin material. Once set, it is shaped to fit the prepared tooth and any rough or sharp edges is removed. Temporary cement is used to secure the temporary crown in place. After placing the temporary crown, the dentist would also check to ensure that the teeth bite together properly correctly. Temporary crowns are important because it helps to prevent the prepared tooth from shifting; it prevents infections and germs from getting to the prepared tooth, and it prevents over hypersensitivity to pressure and temperature and. The temporary crown should not come off but if it does, quickly call your dentist to have it re-cemented.

Placing the Permanent Crown

Fabricating the permanent dental crown usually takes between 7 to 10 business days. When you make the final visit to your dentist to have the permanent crown placed, your dentist would begin the procedure by numbing the prepared tooth and neighboring gingival tissues with a general anesthetic. The dentist then cleans and completely dries the prepared tooth thoroughly before placing the permanent crown. The dentist would also check if there is a right contact between the permanent crown and the adjacent teeth. Too tight contact would cause a problem when flossing, no contact creates unnecessary dental gaps that lodge food bits. This may subsequently lead to tooth decay. Too tight contacts require a small reduction in adjacent teeth (not the new crown) while no contact requires that the new crown be sent back to the dental lab to be remade.

Once the permanent crown fits of the prepared tooth satisfactorily, cementation begins. Excess cement is removed from your mouth and curing light is used again to firmly set the cement. You would be asked to floss in order to remove any excess cement from in between the teeth. Your dentist would use a dental scaler to remove excess cement from below the gumline and around the tooth.

Checking the Bite

After waiting for the permanent crown to set – usually about 10 mins, your dentist would check how your teeth bite together. This aspect is very important because a high bite can cause tooth pain or tooth sensitivity. Any discovered high spot must be carefully reduced to match the opposing tooth.

After the whole dental crown procedure, your dentist should give you some post-operative instructions, which you must carefully follow. Nevertheless, if after some days after the procedure you notice any unusual thing with your dental crown, immediately consult your dentist to have your dental crown examined.
