Dental Crowns – What They Are and When You Might Need One

Knightsfield Dental Practice

12th March 2026

If your dentist has recommended a dental crown, you might be wondering what it is and
why it’s needed. Dental crowns are one of the most common and effective treatments used
in modern dentistry to restore damaged teeth and protect your smile.
Here at Knightsfield Dental Practice in Welwyn Garden City, we regularly use dental crowns
to help patients restore the strength, function, and appearance of their teeth.
In this blog, we’ll explain what dental crowns are, when they’re used, and what you can
expect from the treatment.

What Is a Dental Crown?


A dental crown is a custom-made cap that fits over a damaged or weakened tooth. It
restores the tooth’s shape, strength, and appearance while protecting it from further
damage.


Crowns are designed to look and function just like natural teeth, so once fitted, most people
won’t be able to tell the difference.

They are commonly made from materials such as:

  • Porcelain or ceramic (very natural looking)
  • Porcelain fused to metal
  • Gold or metal alloys
  • Zirconia (extremely strong and durable)

At Knightsfield Dental Practice, your dentist will recommend the most suitable material
depending on the location of the tooth and your individual needs.

When Is a Dental Crown Needed?


Dentists may recommend a crown in several situations.

  • Teeth that are cracked, worn down, or weakened can benefit from a crown to
    prevent further damage and restore strength
  • Teeth that have undergone root canal treatment can become more fragile over time.
    A crown helps reinforce the tooth and protect it from breaking
  • If a tooth is significantly damaged or worn down, a crown can rebuild its shape and
    restore normal chewing function
  • When a tooth has a large filling and limited natural tooth structure remaining, a
    crown can provide long-term protection
  • Dental crowns can also improve the appearance of discoloured, misshapen, or
    uneven teeth

What Happens During Crown Treatment?


At Knightsfield Dental Practice in Welwyn Garden city, dental crown treatment usually takes
two appointments.
During your first visit, your dentist will:

  • Examine and prepare the tooth
  • Remove any decay or old fillings if necessary
  • Shape the tooth so the crown fits securely
  • Take digital scans (no messy impressions)
  • A temporary crown will be placed to protect the tooth while your permanent
    crown is created in a dental laboratory

At the second visit, the temporary crown is removed and your custom-made crown is
carefully fitted and bonded into place.
Your dentist will check your bite and make sure the crown feels comfortable and natural.

How Long Do Dental Crowns Last?


With good oral hygiene and regular dental check-ups, dental crowns can last 10–15 years or
even longer.
Here at Knightsfield Dental Practice, we always encourage patients to maintain good oral
hygiene to help their restorations last as long as possible.

To care for your crown:

  • Brush twice a day with fluoride toothpaste
  • Clean between your teeth daily with floss or interdental brushes
  • Avoid biting very hard foods or objects
  • Attend regular dental check-ups and hygiene appointments

Are Dental Crowns Painful?


Dental crown treatment is usually very comfortable and carried out under local anaesthetic.
Most patients feel little to no discomfort during the procedure.
You may experience mild sensitivity for a few days after the tooth is prepared, but this
normally settles quickly.

If you have a damaged, weakened, or heavily filled tooth, a dental crown may be the best

I recently had some dental issues with broken teeth and saw Maya for a check-up. Maya gave me options to get my teeth repaired, and I now have 2 lovely new white fillings. I had also misplaced my denture, and Maya made me a new one, which fits so well and is so comfortable. The treatment from start to finish was explained in detail, and I’m really happy with the final results. I highly recommend this dental practice and am pleased to have found such a friendly, helpful team.

Today I had the ‘pleasure’ of a shiny new filling by Nishma, who has become a bit of a household name around here! The kids love her, and now, I have to pretend to be “Dentist Daddy” when brushing their teeth (inspired by Nishma)!

Zero pain.
100% friendliness.
On time.
In and out in 30 minutes.

As always, a lovely experience. Well, aside from the bill, I guess, but thanks to the UK Govt, we have to pay for dental treatment these days, and Nishma’s expertise comes at a fair and appropriate cost. Thanks, Nishma (and your lovely colleague) for a smooth experience (and smooth filling too)!

So grateful for the care and attention given at this practice every time I attend. Most recently to Maya, Ishira and Sarah for their patience, care in getting me seen and treated as quickly as possible. The phone call to check on me the next day is such a lovely touch; I have never had that at any other dental practice before. Highly recommend this practice!

Very professional team. Always on time. Very clean premises. Friendly staff. They seem up-to-date with new techniques and equipment. They take pride in their work. I have had several dentists at this practice over the years, but they are all very good at their job. Can recommend.

Recently changed my dentist to a local one and I have found all the staff here very friendly, caring and most importantly, understanding in terms of my ongoing oral health care. Treatment has been exceptional, easy and importantly pain pain-free and appropriate. Thank you, Anita, Maya and the team.

Totally recommend this Dental Surgery! Maya and her team were very professional and kind. I cannot express how grateful I am to have new crowns and a bridge so that I can smile with confidence. They talked me through every stage, and the final result was brilliant.

I had an old filing replaced. The procedure was delivered very well, and in a nice, calm atmosphere. The anaesthetic took quite a long time to ease off – more like 4 hours before I could feel my bottom lip and cheek, but I’d rather that than feel the procedure (which I didn’t).

I had an old filling that had to be replaced, and I had the treatment today. I can honestly say it was the most relaxing treatment; I didn’t feel a thing, and the dentist and her dental nurse were brilliant.

My treatment was concisely explained from start to finish, including aftercare. I was reminded of each appointment both by phone and email. The professionalism and diligence of Maya, Sarah and all staff were faultless.

I had to go to this practice as an emergency, being a very nervous patient, I can not tell you how nice they were. The dentist informed me of what treatment should be done, and the dental nurse was lovely and held my hand throughout the tooth extraction; they even gave me a coping strategy to use. Cannot recommend them enough, all staff were lovely and friendly.

Happy Easter!
Wishing everyone a happy and peaceful bank holiday weekend 
Love from Maya and the team 🐰🥚🫶🏼

...

With bank holiday approaching, don’t ignore the warning signs 🚨 on dental emergencies. 

This X-ray shows a clear infection at the root of the tooth — often this can quickly become painful if left untreated.

Dental infections don’t always start with severe pain, but they can progress fast. Early diagnosis is key to preventing more complex treatment.

If you’re experiencing discomfort, swelling, or something doesn’t feel right, don’t wait — get it checked.

We’re here for emergency appointments to diagnose, treat, and protect your smile.

We have emergency appointments available still for Thursday 2nd April if you require our services.

8 years later… and still going strong 💪🦷

This dental implant was placed 8 years ago by @dr_maya_dentist, and the results speak for themselves — stable, healthy bone levels and a restoration that’s still functioning beautifully.

Long-term success like this comes down to precise planning, quality treatment, and great patient care.

Reliable. Durable. Built to last.

A smile transformation at any age ✨

This before & after shows how powerful a simple refresh can be. We started with professional whitening to brighten the smile, followed by edge bonding to restore shape and create a more even, natural finish.

Whitening isn’t just for the young — it’s for anyone who wants to feel more confident in their smile.

Subtle changes. Big impact. 🤍

...

A confident smile starts with balance ✨

This transformation was achieved with 11 zirconia crowns, restoring not just the appearance, but the function of the bite. By carefully correcting alignment and symmetry, we created a smile that looks natural, harmonious, and beautifully aesthetic.

Results like this aren’t just about teeth — they’re about comfort, confidence, and long-term oral health.
