How Long Do Dental Crowns Last?

How Long Do Dental Crowns Last?

You may have heard the words “dental crowns” being thrown around at your dental office, but you probably have a lot of questions as to what they’re for, how they’re made, and how long they last. Or, perhaps you just received your new crown and are wondering how to look after it properly and when you’ll need to have a touchup. Regardless, there is a lot to learn about this magnificent cosmetic dentistry solution which we’ll go into more detail about below.

Reasons Your Dentist Will Place A Dental


A dental crown, also referred to as a cap, can be used for a couple of different reasons.

Decayed Tooth

If you’re experiencing tooth decay but don’t need the entire tooth removed, a dental crown will fit over the prepared tooth just like a cap after the tooth has been prepared. First and foremost, the decay will need to be removed and a mould will need to be created which will then be sent to a dental lab. In the meantime, you’ll likely be given a temporary crown until your permanent crown is ready. Permanent crowns will be permanently cemented to the prepared tooth.

Broken Tooth

If you’ve experienced trauma to the mouth and have broken a tooth that can’t be restored with veneers, this is where a crown will come into play. The crown restores the broken tooth’s appearance and will protect it from further damage. As described above, the damaged tooth will need to be prepared so the crown can fit over it comfortably like a cap.

Dental Implant Crown

If your decayed or broken tooth is beyond saving, the best thing is to have it removed. However, leaving gaps in your smile can cause further dental complications. This is where a dental implant can be a great solution in replacing the entire tooth structure – from the root up. A titanium screw will be surgically attached to your jawbone and once that heals, a dental crown will be attached on top.

What Are Dental Crowns Made From?

Porcelain is the most popular type of crown material because of its ability to look and feel just like a natural tooth. They’re also good options for patients who may have metal allergies. Porcelain crowns are incredibly durable and can last upwards of 10-15 years before requiring a touchup. Similar to porcelain are ceramic crowns.

Then there are porcelain fused to metal crowns. Since it has porcelain, it will also be matched to the colour of your natural teeth as the inside will be made from metal alloys and the outside porcelain. They can be a bit more affordable and just as durable as all-porcelain, especially when used on back molars.

The least popular option is composite resin crowns. These types of crowns last, on average, 5-10 years. While they look natural and are the cheapest option, the material can break down more easily over time.

When it comes to temporary crowns before you receive your permanent one, just remember that it is indeed temporary. They’re not meant to last more than a few weeks, so you should ensure you’re not brushing your teeth roughly or eating hard foods that can damage it and expose the underlying tooth.

Dental Crowns Require Proper Care To Last

While these are just general guidelines on how long dental crowns can last, it’s really up to the patient to determine how long they’ll last. Maintaining proper oral hygiene and booking regular dental check ups is incredibly important in ensuring your crowned tooth remains healthy and in good condition. Things that can negatively affect dental crowns and cause them to fail much earlier include:

If your crown feels loose or has been knocked out or damaged in any way, you should see your dentist right away in order to protect the tooth abutment underneath.

If you maintain a healthy oral hygiene routine but you still feel a loose crown, it may just be because the cement is starting to wear down. This can easily be fixed during one visit to your dentist.
