Dental Crowns: Procedure Explained

Getting a dental crown typically requires two visits to the dentist. Here is an overview of what you can expect during each phase of the procedure:

First Visit: Tooth Preparation and Impression

1. Initial Examination and Preparation
   During the first visit, your dentist will begin by examining the tooth and taking X-rays to ensure that there is no underlying infection or further damage. If the tooth has extensive decay, it may need to be cleaned and treated before the crown can be placed.
2. Shaping the Tooth
   To make room for the crown, the dentist will reshape the damaged tooth. This involves removing a portion of the tooth’s outer structure to ensure that the crown will fit comfortably over the remaining tooth. If the tooth is significantly damaged, the dentist may also use a filling material to build up the tooth before proceeding with the crown preparation.
3. Taking Impressions
   Once the tooth is reshaped, the dentist will take an impression of the tooth and the surrounding teeth. This is typically done using a moulding material or, in some cases, a digital scanner. The impression is sent to a dental laboratory where your custom crown will be created to match the shape, size, and colour of your natural teeth.
4. Temporary Crown
   While your permanent crown is being made (usually taking two to three weeks), your dentist will place a temporary crown over the prepared tooth. This is to protect the tooth and allow you to continue using it normally until your permanent crown is ready. The temporary crown is held in place with a weak adhesive, which is why it is important to be careful when chewing, especially on hard or sticky foods.

Second Visit: Fitting the Permanent Crown

1. Removing the Temporary Crown
   When you return for your second visit, the dentist will remove the temporary crown and check the fit of the permanent crown. The crown will be placed over the prepared tooth to ensure that it fits correctly and matches your bite.
2. Adjustments
   If necessary, the dentist will make adjustments to the crown to ensure that it fits comfortably and aligns properly with the surrounding teeth. This may involve trimming or reshaping the crown to ensure that it does not interfere with your bite or cause any discomfort.
3. Cementing the Crown
   Once the fit and appearance are satisfactory, the dentist will use a strong dental cement to permanently bond the crown to the tooth. The cement is allowed to set, and your dentist will check your bite one more time to make sure everything is aligned correctly.
4. Final Inspection
   After the crown is cemented in place, the dentist will perform a final check to ensure that the crown is fully secure and that your bite feels natural. You may be asked to bite down gently to test how the crown feels when you chew.

Recovery Time and What to Expect After the Procedure

The recovery process after a dental crown procedure is typically quick, with most patients resuming normal activities the same day. However, there are a few things to keep in mind during the healing process:

1. Anaesthesia Wearing Off
   If local anaesthesia was used during the procedure, it will wear off after a few hours. You may feel some mild discomfort or tenderness around the treated area as the anaesthesia subsides, but this is usually temporary and can be managed with over-the-counter pain relievers like paracetamol or ibuprofen.
2. Sensitivity
   It is common to experience some sensitivity to hot, cold, or pressure after the placement of a dental crown, particularly if the tooth was significantly damaged or had a root canal treatment. This sensitivity should improve within a few days to a week. If the discomfort persists or worsens, contact your dentist to ensure that there are no underlying issues.
3. Temporary Discomfort
   For the first few days after the crown is placed, you may feel mild discomfort, especially if the tooth was prepared significantly. This discomfort should subside once your mouth adjusts to the new crown.

Post-Care Instructions for Dental Crowns

To ensure that your dental crown lasts for many years and continues to function well, proper aftercare is essential. Here are some important post-care instructions to follow:

1. Avoid Chewing on Hard or Sticky Foods
   After the crown is placed, avoid chewing on hard foods such as nuts, ice, or hard candies, as these could potentially damage the crown. Similarly, sticky foods like caramel or chewing gum could dislodge the crown. Stick to softer foods for the first few days until you feel comfortable chewing with the crowned tooth.
2. Maintain Good Oral Hygiene
   Continue to brush and floss your teeth as usual, but be careful around the crown area, especially if the gums are still a little sensitive. Use a soft-bristled toothbrush to clean the area around the crown, and floss gently to avoid dislodging the crown. It’s also important to floss between your teeth to prevent plaque build-up around the crown.
3. Avoid Using Your Crowned Tooth for Excessive Pressure
   While the crown is designed to withstand normal chewing forces, try to avoid using the crowned tooth to bite down on excessively hard items, such as bones or fingernails. This can put stress on the crown and the underlying tooth structure.
4. Monitor for Issues
   If you experience any unusual symptoms after the crown is placed, such as pain, sensitivity that does not subside, or if the crown feels loose, contact your dentist. These could be signs that the crown is not properly fitted or that the tooth underneath is experiencing issues.
5. Regular Dental Check-Ups
   It is important to continue with your regular dental check-ups, as your dentist will need to monitor the condition of your crown and ensure that it is functioning properly. During these visits, your dentist can also clean and check the surrounding teeth and gums for any potential problems.

The dental crown procedure is an effective and relatively straightforward way to restore a damaged or weakened tooth. While the process involves two visits, the results can provide long-lasting benefits in terms of both functionality and aesthetics. With proper care and maintenance, your crown should serve you well for many years, protecting your tooth from further damage and helping to maintain your overall oral health.

If you have any concerns after the procedure or experience discomfort, do not hesitate to reach out to your dentist for advice. With careful attention to post-care instructions and regular dental visits, your crown will help you enjoy a functional smile for years to come.
