A cracked, damaged, or dislodged dental crown can be an unsettling experience. Whether it happens while eating, during an accident, or seemingly out of nowhere, many patients find themselves searching online for answers about emergency crown placement and what steps they should take next.
Emergency crown placement is a common procedure that dentists in London carry out regularly to restore and protect damaged teeth. Crowns serve as protective caps that sit over weakened or broken teeth, helping to maintain their structure and function.
This article explains what emergency crown placement involves, the reasons it may be needed, how the procedure works, and what you can do to look after your oral health during recovery.

What Is Emergency Crown Placement?
Quick answer: Emergency crown placement is the urgent fitting of a dental crown to protect a damaged, fractured, or exposed tooth. It may be needed when a previous crown is lost, a tooth breaks significantly, or when a tooth requires immediate protection from further damage or infection. A dentist will assess the tooth during a clinical examination to determine the most suitable treatment approach.
Common Reasons You May Need an Emergency Crown
Fractured or Broken Teeth
A sudden impact to the face, biting down on something unexpectedly hard, or even long-term wear can cause a tooth to crack or fracture. When the damage is extensive enough that a filling alone cannot restore the tooth, a crown may be recommended. For further guidance, our article on when a broken tooth needs a crown explores this topic in more detail.
A Lost or Dislodged Crown
Existing crowns can sometimes become loose or fall off entirely due to the gradual breakdown of dental cement, decay developing underneath, or physical trauma. When a crown is lost, the prepared tooth underneath is often vulnerable and sensitive.

In cases where decay has significantly compromised a tooth's structure, a crown may be required to restore its integrity. In some situations, patients may face a choice between a crown and extraction — our crown vs extraction guide can help you understand the considerations involved.
Following Root Canal Treatment
After a root canal procedure, the treated tooth can become more brittle over time. A crown is frequently recommended to provide long-term protection.
Understanding the Dental Science Behind Crowns
Each tooth consists of several layers. The outermost layer is enamel, the hardest substance in the human body. Beneath the enamel lies dentine, a slightly softer layer that forms the bulk of the tooth's structure. At the centre is the pulp chamber, which contains nerves, blood vessels, and connective tissue.
When enamel is cracked, chipped, or worn away, the underlying dentine becomes exposed. Dentine contains microscopic tubules that lead towards the pulp, which is why damage to this layer can cause sensitivity. If the damage extends to the pulp itself, there is a risk of infection.
A dental crown essentially replaces the protective function of damaged enamel. By covering the entire visible portion of the tooth above the gum line, the crown shields the vulnerable inner layers from bacteria, temperature changes, and biting forces.
What to Expect During an Emergency Crown Appointment
Initial Assessment
Your dentist will begin by examining the affected tooth, which may include taking dental X-rays to assess the extent of the damage, the health of the tooth root, and the condition of the surrounding bone.
Tooth Preparation
If a crown is deemed suitable, the tooth will be carefully prepared. This typically involves reshaping the tooth to create a stable foundation. Any decay or damaged material will be removed. A local anaesthetic is usually administered.
Impression or Digital Scan
An impression or digital scan of the prepared tooth is taken. This provides the precise measurements needed to fabricate a crown that fits accurately.

Temporary Crown Placement
In many cases, a temporary crown is fitted on the same day to protect the tooth while a permanent crown is being made.
Permanent Crown Fitting
At a subsequent appointment, the temporary crown is removed, and the permanent crown is checked for fit, colour, and bite alignment before being cemented into place.
When Professional Dental Assessment May Be Needed
- Persistent or worsening toothache that does not respond to over-the-counter pain relief
- A crown that has come loose or fallen off, leaving the underlying tooth exposed
- Visible cracks or fractures in a tooth, particularly if accompanied by discomfort
- Swelling around the gum or jaw area
- Increased sensitivity to hot, cold, or sweet foods and drinks
- Difficulty chewing or biting due to a damaged or weakened tooth
If you are experiencing a dental emergency in London, prompt professional advice can help ensure you receive appropriate care.
Caring for Your Crown After Placement
Immediately After Placement
If a local anaesthetic was used, take care not to bite your cheek, tongue, or lip while the area is still numb. Stick to soft foods for the first few hours.
With a Temporary Crown
Avoid sticky or hard foods that could dislodge it. Chew on the opposite side of your mouth where possible, and be gentle when brushing and flossing around the temporary crown.
Long-Term Crown Care
Once your permanent crown is in place, treat it as you would a natural tooth. Brush twice daily with a fluoride toothpaste, clean between your teeth, and attend regular dental check-ups.
Prevention and Oral Health Advice
- Maintain a consistent oral hygiene routine — brushing twice daily and cleaning between your teeth
- Attend regular dental check-ups to identify early signs of wear, decay, or damage
- Wear a mouthguard if appropriate for contact sports or bruxism
- Be mindful of what you eat — be cautious with particularly hard items
- Address dental issues promptly — seeking advice sooner can sometimes prevent a minor issue from progressing
Key Points to Remember
- Emergency crown placement is a common procedure used to protect damaged, fractured, or exposed teeth
- Crowns act as protective caps that restore a tooth's shape, strength, and function
- A temporary crown may be placed during the initial appointment, with a permanent crown fitted at a follow-up visit
- Symptoms such as persistent pain, a lost crown, visible fractures, or swelling may benefit from prompt dental assessment
- Good oral hygiene, regular check-ups, and protective measures can help reduce the risk of dental emergencies
Frequently Asked Questions
How long does an emergency crown appointment take?
An emergency crown appointment typically takes between 30 minutes and one hour, depending on the complexity of the case. During this time, the dentist will assess the damage, prepare the tooth if necessary, and fit a temporary crown. In practices equipped with same-day fabrication technology, a permanent crown may occasionally be placed in a single visit.
Is emergency crown placement painful?
Most patients find the procedure comfortable, as a local anaesthetic is used to numb the area before any preparation work begins. After the anaesthetic wears off, mild sensitivity or discomfort is normal and usually settles within a few days.
How long does a dental crown last?
The lifespan of a dental crown varies depending on the material used, the location of the crown, and how well it is cared for. With proper maintenance, well-maintained crowns can last many years. Your dentist will monitor the condition during routine examinations.
Can I eat normally with a temporary crown?
While wearing a temporary crown, it is advisable to exercise some caution with your diet. Avoid sticky foods such as toffee or chewing gum. Hard foods should also be eaten carefully. Once your permanent crown is fitted, you should be able to return to your normal diet.
What should I do if my crown falls off?
If your crown comes off, keep it safe and clean. Avoid attempting to reattach it with household adhesives. A temporary dental cement product from a pharmacy may offer short-term relief. Contact your dental practice as soon as possible to arrange an appointment.
