If you’ve ever sat in a dentist’s chair and heard the words “dental cap” and “dental crown” used almost interchangeably, you’re not alone. It’s one of the most common sources of confusion in general dentistry, and for good reason. The terminology can feel inconsistent, even among dental professionals.
The short answer? A dental cap and a dental crown are the same thing. But understanding why both terms exist, what types of crowns are available, and when you might need one can help you feel far more confident about your treatment options. This guide covers everything you need to know.
What is a dental crown?
A dental crown is a custom-made restoration that fits over a damaged or weakened tooth, covering it entirely from the gum line up. Think of it as a protective shell, one that restores the tooth’s shape, strength, and appearance while shielding it from further damage.
Crowns are typically recommended when a tooth has been cracked, broken, or significantly worn down, or when decay has progressed to the point where a standard filling can no longer provide adequate support. They’re also commonly placed after root canal treatment to protect the newly restored tooth.
At Fitzroy Dental Practice, crowns are crafted using advanced digital scanning technology and made to measure for each patient. The result is a restoration that fits precisely, functions naturally, and blends seamlessly with surrounding teeth.
Does Getting a Dental Crown Hurt? What to Expect at Your Appointment
The short answer: no, not during the procedure. Dental crowns are placed under local anaesthetic, meaning the tooth and surrounding gum are fully numb before any preparation begins. Most patients feel pressure and vibration, not pain.
Here is what happens at each stage:
1. Tooth Preparation Appointment
Your dentist administers a local anaesthetic injection, the only part of the appointment where you may feel a brief sting. Once the area is numb (usually within two to three minutes), the tooth is gently reshaped to create room for the crown. You should feel no pain during this stage. If you do, let your dentist know immediately, and more anaesthetic can always be added.
A highly accurate impression or digital scan is then taken, and a temporary crown is placed to protect the prepared tooth while your permanent crown is crafted in our laboratory.
2. Temporary Crown Stage
Temporary crowns are made from a softer material and are not bonded as firmly as permanent crowns. During this period, usually one to two weeks, you may notice:
- Mild sensitivity to hot, cold, or sweet foods and drinks
- Slight discomfort if the temporary crown sits too high on the bite
- Occasional tenderness around the gum margin
These sensations are normal and typically mild. Over-the-counter pain relief (ibuprofen or paracetamol) is usually sufficient. Avoid hard or sticky foods during this phase.
3. Permanent Crown Fit Appointment
The temporary crown is removed, and the permanent crown is tried for fit, colour, and bite before being permanently bonded. Local anaesthetic is not always required for this appointment, though your dentist will offer it if there is any sensitivity. Any bite adjustments are made chairside.
After the Procedure: What Is Normal?
Once the anaesthetic wears off, usually two to four hours after the appointment, you may notice:
- Mild soreness around the gum for two to three days
- Sensitivity to temperature for one to two weeks, which fades as the tooth settles
- Slight bite awareness for a few days
Significant or worsening pain after crown placement is uncommon. If pain intensifies beyond three to four days, contact your dentist. This can indicate a bite that needs minor adjustment or, rarely, that the tooth’s nerve has been affected.
At Fitzroy Dental Practice, our team is experienced in making crown procedures as comfortable as possible. We take time with anaesthetic delivery and are always available to answer questions between appointments.
How Long Do Dental Crowns Last? Lifespan by Material
A well-placed dental crown is a long-term investment. How long yours lasts depends primarily on the material chosen, the position of the tooth, and how well you maintain it.
| Crown Material | Expected Lifespan | Strengths | Limitations |
|---|---|---|---|
| Porcelain (all-ceramic) | 10–15 years | Highly aesthetic; matches natural tooth colour; metal-free | Less resistant to fracture than zirconia in heavy bite positions |
| Zirconia | 15–20+ years | Exceptional strength; tooth-coloured; suitable for molars | Slightly higher cost than porcelain |
| Porcelain-fused-to-metal (PFM) | 10–15 years | Good aesthetics with metal core strength | Dark metal line may appear at the gumline over time |
| Gold / full metal | 20+ years | Most durable; gentle on opposing teeth; rarely fractures | Not tooth-coloured; used mainly on back molars |
| NHS crown (typically PFM or acrylic over metal) | 7–10 years (varies) | Covered under Band 3 treatment | Material options limited compared to private treatment |
Factors That Affect Crown Longevity
- Tooth position molars withstand greater bite forces than front teeth and may wear crowns faster.
- Bruxism (tooth grinding) patients who grind at night benefit significantly from a custom night guard to protect their crowns
- Oral hygiene decay can develop at the crown margin if the area is not cleaned thoroughly; flossing around the crown is essential.
- Diet, biting hard objects (ice, pen lids, hard sweets) increases fracture risk, particularly for an all-ceramic crown.s
- Regular check-ups and six-monthly professional reviews allow early identification of any issues before they become costly.
NHS vs Private Crown Durability
NHS crowns are functional and clinically sound, but material choices are limited. Private crowns at Fitzroy Dental Practice are crafted in collaboration with leading London dental laboratories using high-specification ceramics and zirconia, with greater attention to individual fit, aesthetics, and longevity. The difference is most visible on the front teeth, especially for patients who grind.
We will always discuss which material suits your specific tooth, bite, and aesthetic goals during your consultation.
How Much Does a Dental Crown Cost in London? NHS vs Private
Crown costs in the UK vary significantly between NHS and private treatment. Below is a clear breakdown to help you understand what to expect.
NHS Crown Cost
NHS dental crowns fall under Band 3 treatment, which covers more complex restorative work, including crowns, bridges, and dentures. The current Band 3 charge is £319.10 (April 2024 rate). This charge covers the entire course of treatment, not just the crown, and is the same regardless of how many crowns are placed within that treatment plan.
NHS crowns are clinically effective. However, material options are restricted, and aesthetics may be limited compared to private alternatives.
Private Crown Cost at Fitzroy Dental Practice
Private crown costs in London typically range from £700 to £1,500+ per crown, depending on material, tooth position, and complexity. At Fitzroy Dental Practice, our cosmetic dentists provide a detailed, itemised cost plan at your consultation so you know exactly what is involved before any treatment begins.
| Crown Type | Typical Private Cost (London) | NHS Available? |
|---|---|---|
| All-ceramic / porcelain | £800 – £1,200 | Limited |
| Zirconia | £900 – £1,400 | No |
| Porcelain-fused-to-metal (PFM) | £700 – £1,100 | Yes (Band 3: £319.10) |
| Gold / full metal | £900 – £1,300 | Yes (Band 3: £319.10) |
What Affects the Final Cost?
- Material selected zirconia and high-specification ceramics carry a higher laboratory cost.s
- Tooth position, posterior (back) teeth may require more preparation time
- Preliminary work, if a root canal treatment, post-and-core build-up, or gum treatment is required before the crown is placed, is cost separately
- The number of crowns in multi-crown smile rehabilitation plans may be offered at adjusted rates
At Fitzroy Dental Practice, there are no hidden fees. Your written treatment plan will detail every cost before you agree to proceed. For current pricing, visit our fees page or speak to our team during your free consultation.
Types of Dental Crowns: Porcelain, Zirconia, PFM and Metal Explained
Not all crowns are the same material, and the right choice depends on the tooth being restored, your bite, and your aesthetic priorities. Here is a practical comparison of the four main crown types used in private dental practice.
| Material | Appearance | Strength | Best for | Typical Lifespan |
|---|---|---|---|---|
| All-ceramic / porcelain | Excellent, the closest to natural enamel translucency | Good; may chip under heavy bite forces | Front teeth; aesthetic-priority cases | 10–15 years |
| Zirconia | Very good tooth-coloured with good light transmission | Excellent; withstands heavy forces | Molars; bruxism patients; all positions | 15–20+ years |
| Porcelain-fused-to-metal (PFM) | Good; opaque core may show at the gumline over time | Very good | Back teeth, longer bridges, where cost is a factor | 10–15 years |
| Gold / full metal | Not tooth-coloured; silver/gold appearance | Outstanding, most durable option available | Lower molars, where aesthetics are less critical | 20+ years |
Which Crown Material Is Right for You?
For front teeth and smile-line restorations, all-ceramic or zirconia crowns offer the most natural appearance. For back teeth that bear heavy bite pressure, zirconia or PFM provides greater fracture resistance. For patients with confirmed bruxism (tooth grinding), zirconia is usually the recommended choice, as it is strong enough to withstand grinding forces that would chip a porcelain crown.
At Fitzroy Dental Practice, our dentists will always recommend the material that best suits your clinical situation and aesthetic goals, not the most expensive option. Material choice is always explained and agreed upon before treatment begins.
What is a tooth cap, and how does it differ?
Here’s where the confusion tends to creep in. A “tooth cap” is simply an older, more colloquial term for a dental crown. Both refer to the same restorative treatment. Over time, “crown” became the more clinically accepted term, but “cap” has stuck around in everyday conversation, and many patients still use it.
So when someone says they need a crown cap, a tooth cap, or a dental crown, they’re almost certainly talking about the same procedure. The terminology varies by region, generation, and habit, but the treatment itself is consistent.
Types of dental crowns
One area where crowns do differ is in the materials used to make them. Each option comes with its own set of advantages depending on the location of the tooth, your aesthetic preferences, and your budget.
Metal crowns
Gold and other metal alloys are among the most durable crown materials available. They wear well, rarely chip, and require less removal of the natural tooth structure than some alternatives. The obvious drawback is that their appearance, metal crowns are highly visible, which makes them better suited to back teeth that aren’t in the smile line.
Porcelain-fused-to-metal crowns
These crowns combine a metal base for strength with a porcelain outer layer for aesthetics. They’ve been widely used for decades and offer a reasonable balance between durability and appearance. However, the metal beneath can sometimes cause a faint dark line near the gum, particularly as the gum line changes over time.
All-ceramic crowns
All-ceramic or all-porcelain crowns offer the most natural-looking result. They’re a popular choice for front teeth because they mimic the translucency and colour of natural enamel very closely. At Fitzroy Dental Practice, advanced ceramics are used specifically to achieve a discreet, aesthetic finish.
Zirconia crowns
Zirconia has become one of the most favoured materials in modern dentistry. It’s exceptionally strong, biocompatible (meaning it’s unlikely to cause any allergic reaction), and can be milled to a natural-looking finish. Zirconia crowns work well for both front and back teeth.
Resin crowns
Composite resin crowns are generally the most affordable option, but they’re also the least durable. They’re more prone to fracturing and wear over time, making them better suited as temporary restorations rather than long-term solutions.
How much do dental crowns cost?
Crown costs vary depending on the material chosen, the complexity of the case, and the practice you attend. As a general guide, all-ceramic and zirconia crowns tend to sit at the higher end of the price range, while resin and metal crowns are typically more affordable.
For patients at Fitzroy Dental Practice, flexible 0% finance options are available, allowing treatment costs to be spread over 12 months with no upfront payment required. This makes it possible to proceed with the right crown for your clinical needs rather than defaulting to a cheaper option out of financial pressure.
When should you choose a dental crown?
Crowns are recommended in a range of situations, including:
- Teeth that are cracked, chipped, or fractured
- Heavily filled teeth where the remaining natural structure is insufficient to support another filling
- Teeth that have undergone root canal treatment can leave the tooth more brittle
- Cosmetic improvements where the shape, colour, or size of a tooth needs correcting
- Dental bridge support, where a crown anchors the bridge to an adjacent natural tooth
In some cases, a crown and another restoration may be used together. For example, a crown may be placed over an implant, or alongside a bridge, to achieve the best functional and aesthetic outcome. Your dentist will advise on the most appropriate combination based on your specific situation.

Frequently Asked Questions
How long do tooth caps last?
Tooth caps typically last between 10 to 15 years with proper care. Regular dental check-ups help maintain their longevity and detect any potential issues early.
Why do dentists push for crowns?
Dentists recommend crowns to restore damaged teeth, providing protection and strength. Crowns improve tooth function, prevent further decay, and enhance the tooth’s appearance.
How many times can a tooth be crowned?
A tooth can be crowned multiple times, depending on the condition of the remaining tooth structure. However, each new crown requires sufficient healthy tooth material to support it.
What is better, a cap or crown?
A crown and a cap refer to the same dental restoration, offering protection, strength, and aesthetic improvement for damaged teeth. Both terms are used interchangeably.
Why do dentists push for crowns?
Dentists recommend crowns to protect weakened or decayed teeth, restore function, and improve aesthetics. Crowns help prevent further damage and avoid tooth extraction.
