Having a dental crown fitted is one of the most effective ways to restore a damaged or weakened tooth, and for many patients, the treatment is far more straightforward than they expect. Understanding what happens at each stage of the process can help ease any anxiety and allow you to approach your appointments with confidence. The crown procedure typically takes place over two visits, with a short waiting period in between while your custom crown is being made in a dental laboratory.
Dental crowns are cap-like restorations that are placed over a prepared tooth to restore its shape, size, strength, and appearance. They are commonly used after root canal treatment, to protect teeth that have become cracked or heavily filled, to restore severely decayed teeth, and to improve the look of misshapen or discoloured teeth. Knowing what to expect at each appointment makes the experience much less daunting.
Before the Procedure: Assessment and Treatment Planning
Before any crown work begins, your dentist will carry out a thorough examination of the tooth. This usually includes dental X-rays to assess the condition of the roots and surrounding bone. If there are signs of infection or significant decay extending into the pulp of the tooth, a root canal treatment may be recommended before the crown is placed. It is important that any underlying problems are resolved first, as placing a crown over an infected tooth will not address the infection and may lead to further complications.
Your dentist will also discuss the material options with you. For NHS patients in Scotland, the material used will be determined on clinical grounds. For private patients, there is usually a choice between porcelain-fused-to-metal, full ceramic (including zirconia), and in some cases full metal crowns for back teeth. Each material has advantages depending on the position of the tooth and the level of aesthetics required.
First Appointment: Tooth Preparation
The first appointment is the longer of the two and involves preparing the tooth to receive the crown. Your dentist will begin by administering a local anaesthetic to numb the area around the tooth. Once you are comfortable and the anaesthetic has taken effect, the preparation work begins.
The dentist will use a drill to reshape the tooth, removing a thin layer from all surfaces. This creates space for the crown to sit over the tooth without making the restored tooth feel oversized or uncomfortable in your bite. The amount of tooth structure removed depends on the type of crown being made and the thickness of material required.
Once the tooth has been shaped, an impression (or mould) is taken. In traditional crown procedures, this involves placing a soft putty material around the prepared tooth to capture an accurate record of its shape. In practices that use digital scanning technology, an intraoral scanner may be used instead, which creates a precise three-dimensional digital model of the tooth without the need for traditional impression materials. This impression or scan is then sent to a dental laboratory, where skilled technicians will use it to fabricate your permanent crown.
The Temporary Crown
Before you leave the first appointment, your dentist will place a temporary crown over the prepared tooth. This temporary restoration is usually made from an acrylic or resin material and is cemented in place with a temporary adhesive. Its purpose is to protect the prepared tooth and maintain your appearance and function while you wait for the permanent crown to be made.
Temporary crowns are not as strong or as well-fitting as permanent ones, so there are a few guidelines to follow during this waiting period:
- Avoid sticky or chewy foods such as toffees, chewing gum, or hard sweets, as these can dislodge the temporary crown.
- Take care when flossing around the temporary crown — slide the floss out sideways rather than pulling it upward, which could lift the crown off.
- If the temporary crown becomes loose or falls off, contact your dentist promptly so it can be re-cemented.
- Some sensitivity to temperature and pressure around the prepared tooth is normal during this period.
The Laboratory Stage
While you go about your daily life, your permanent crown is being crafted by a dental technician in a laboratory. Using your impression or digital scan, the technician builds the crown to precise specifications, ensuring it matches the shape, size, and shade of your surrounding teeth. Depending on the material chosen, the crown may be pressed, milled, or layered by hand. This stage typically takes one to two weeks.
Some modern dental practices use in-house CAD/CAM (Computer-Aided Design and Manufacturing) systems that can mill a ceramic crown on the same day. If this technology is available at your practice, it may be possible to have your crown fitted in a single visit rather than two.
Second Appointment: Fitting the Permanent Crown
When your permanent crown is ready, you will return for your second appointment. The dentist will remove the temporary crown and clean the prepared tooth. The new crown is then tried in place so the dentist can check the fit, the bite, and the appearance before permanently cementing it.
Your dentist will assess:
- Whether the crown sits accurately on the prepared tooth with no gaps or overhangs
- Whether the colour and shape match the surrounding teeth
- Whether your bite feels natural and comfortable when you close your teeth together
- Whether the contacts with adjacent teeth are correct
Minor adjustments can be made at this stage before the crown is cemented. Once you and your dentist are satisfied, the crown is permanently bonded or cemented in place. The procedure is usually carried out under local anaesthetic, though some patients find the fitting appointment comfortable enough without it.
After Your Crown Is Fitted
Once your permanent crown is in place, you may experience some mild sensitivity around the tooth for a few days, particularly to hot and cold temperatures. This is entirely normal and usually resolves on its own. If you notice any pain when biting down, your crown may need a slight bite adjustment, which your dentist can carry out quickly at a follow-up appointment.
According to Leeds Teaching Hospitals NHS Trust guidance on dental crowns, a well-cared-for crown should normally last around 8 to 10 years, though many last considerably longer with good oral hygiene and regular dental visits.
| Stage | What Happens | Typical Duration |
|---|---|---|
| Assessment | Examination, X-rays, treatment planning, material selection | 30–45 minutes |
| First Appointment | Tooth preparation, impression or digital scan, temporary crown placement | 60–90 minutes |
| Laboratory Stage | Permanent crown fabricated by dental technician | 1–2 weeks |
| Second Appointment | Temporary crown removed, permanent crown tried in, adjusted, and cemented | 30–60 minutes |
Caring for Your Crown Long-Term
Crowns do not decay themselves, but the tooth underneath remains vulnerable, particularly at the margin where the crown meets the gum line. Good oral hygiene is therefore just as important after a crown as before. Brush twice daily with a fluoride toothpaste, floss or use interdental brushes daily, and attend regular check-up and hygiene appointments so your dentist can monitor the crown and the surrounding gum tissue.
Certain habits can shorten the lifespan of a crown. Grinding your teeth (bruxism) places excessive force on restorations, and your dentist may recommend a custom-made night guard if this is an issue. Biting fingernails, chewing ice, or using your teeth to open packaging are habits best avoided when you have a crown.
