A dental crown is a cap placed over a damaged, broken, or decayed tooth to restore its look, shape, integrity and functionality. Dental crowns are a versatile dental restoration. 

For your convenience, at Dental Spot, we design and fabricate custom dental crowns in our onsite laboratory to reduce the amount of time you need to spend in the dentist’s chair.   

If you’ve been prescribed a dental crown by your dentist, you may be wondering, how long do crowns last? Many things can affect the average lifespan of dental crowns, from their location in your mouth to your oral healthcare routine and even your diet. Here’s what you need to know about dental crowns and how long they last. 


Why Would You Need a Dental Crown?

If more than 50% of your tooth is damaged, your dentist may consider the tooth irreparable. At this point, the tooth may be extracted, or if the root is healthy, the tooth can be restored using a dental crown

A dental crown is also often recommended if you have a silver filling that is ⅔ the width of the tooth or more. This is because the small amount of remaining tooth structure is weak and easily compromised. 

Dental crowns can serve both restorative and cosmetic purposes. Crowns can be used to:

  • Conceal cracked or severely chipped teeth 
  • Strengthen a tooth after a root canal 
  • Support a damaged or severely decayed tooth with a large filling 
  • Top a dental implant 
  • Mask intrinsic staining
  • Restore a worn or irregular tooth  

We use advanced dental technology to create accurate impressions of your mouth and gums, ensuring a precise fit and a natural-looking smile.


How Long Do Crowns Last?: Different Types of Dental Crowns

At Dental Spot, we focus on ensuring all crowns fit precisely, blend seamlessly with existing teeth, and feel comfortable in your mouth. The material used to make dental crowns can affect their lifespan. At Dental Spot, the type of material we recommend depends on:

  • The location and function of your tooth
  • The health of your oral tissue
  • Your overall health 
  • The amount of tooth that’s visible when you smile 
  • The colour and condition of the surrounding teeth

In modern dentistry, permanent dental crowns are typically made from porcelain and ceramic due to their durability and the characteristics they share with natural teeth. These materials are hypoallergenic and metal-free, minimising the likelihood of an allergic reaction. They can be shaped and coloured to match your existing teeth. 


  • Porcelain

Porcelain is one of the most popular materials for dental crowns because it provides the most natural look. Porcelain dental crowns are also toxic-free and biocompatible because they contain no metal. 


  • Ceramic

Our ceramic crowns are custom made using our in-house dental crown fabricating machine. We use specialist intraoral cameras to take accurate 3D images of your teeth, gums, and jaw, ensuring the crowns are precisely crafted for a perfect fit. This process allows us to create comfortable and natural-looking tooth crowns.


How Long Do Crowns Last?: Factors Affecting Dental Crowns

Some of the factors affecting the lifespan of dental crowns include:


  • Your Oral Care Routine

This means brushing your teeth twice daily, flossing once a day, and using a dentist-recommended mouthwash.

Your dentist should also monitor the health of your dental crown and gum tissue twice a year. 


  • Type of Material 

Regardless of their material, the average lifetime of a dental crown is 5-7 years. However, with proper care, many porcelain and ceramic tooth crowns last up to 10 or 15 years or longer, making them an excellent long term investment for your oral health. 


  • Your Lifestyle 

Some lifestyle choices, such as smoking, can reduce the lifespan of dental crowns. Besides staining them, smoking increases your risk for gum disease, leading to gum recession and instability of your crowns. 


How Long Do Crowns Last? Caring for Dental Crowns

Dental crowns are a long term solution for restoring damaged teeth. While porcelain and ceramic crowns are extremely durable, they still require proper care. Poor oral hygiene, a hard impact due to an accident, or lifestyle choices can cause a dental crown to chip, loosen, or fall out.

The following tips can help extend the lifespan of your dental crown

  • Avoid eating sticky or hard foods
  • Brush, floss, and attend dental checkups regularly
  • Avoid biting your nails, chewing on pens, ice, or other hard objects
  • Don’t open bottles or packages with your teeth
  • Use a mouthguard during sports
  • Ask your dentist about using a nightguard if you grind your teeth
  • Limit your sugar intake

To keep your dental crowns from staining or discolouration, you’ll also want to limit your intake of food and beverages that are rich in tannins like coffee, tea, and red wine. Crowns cannot be cosmetically whitened, so if you intend to whiten your teeth, you’ll need to apply teeth whitening agents to your natural teeth before having tooth crowns installed.
