Top 4 Reasons Your Dental Crowns Keep Breaking

16 241

Aside from bridges and implants, dental crowns are one of the most expensive restorations that you can have performed on your teeth. They’re expensive because they require the expertise of a lab to create so that they fit perfectly in your mouth.

When you have to have your crowns repeatedly replaced, it becomes a considerable expense.

Let’s take a look at the top four reasons that your crowns might break or otherwise fail. Understanding these reasons can help you make those restorations last five to fifteen years or the rest of your life.

Dental Crowns

1. Weak Materials

Resin and porcelain crowns look incredibly similar to your natural teeth. The problem is that they often fail to function with the same resilience as your teeth do when the forces of chewing are applied.

Both types of crowns are prone to cracking, fracturing and failing earlier than other types of crowns. A better alternative is to opt for porcelain-fused-to-metal crowns, which look similar to porcelain crowns while having a metal framework underneath.

2. Bruxism

Grinding your teeth when you sleep or applying too much force when you chew is a common problem. Many people don’t even realize that they’re doing it.

The effects these forces can have are quite surprising. Grinding your teeth, which is known as bruxism, can crack teeth, force fillings to fail, and cause even the strongest metal crowns to break.

One of the most effective ways to prevent bruxism is to wear a custom guard when you sleep. Your dentist will be able to provide you with the best solution for your bruxism if you have it.

3. Improper Installation

A crown is designed to fit tightly over the prepared tooth. It is then glued in place in such a way that the gum tissue seals the interior from the eroding effects of bacteria.

When your crown is improperly crafted or installed, it will begin to fail in the inside. This can lead to a gradual decay that makes your crown and the underlying tooth break.

The best way to avoid this is to ensure that the dentist installing your crown knows what they’re doing. Whether you decide to research Dr. Bruce Hartley from Woodcreek Dental Care or a dentist from a clinic in your particular locale, look for customer reviews and recommendations to get a feel for their work.

4. Hard or Sticky Foods

The last reason your crowns might fail pertains to what you eat. Foods that require you to bite harder than normal or those that are sticky can cause your crowns to fail sooner rather than later.

The best way to prevent this is to minimize how often you eat these foods. You may even want to chew on teeth that don’t have crowns to ensure that you can spare your crowns any unnecessary punishment.

Keeping Your Crowns in Working Order

Crowns are designed to last anywhere from five to fifteen years, but they can last the remainder of your life with the proper care. Consult with your dentist if your crowns continue to break to see what other solutions they can devise for restoring your teeth.

    Thanks for sharing this. You’re right, it’s felt like it’s pretty often that my dental crowns break; why is this happening? Now that you mention it, I think it could be bruxism. I suppose I’ll have to talk to my dentist about it when he fixes my crowns. Do you have any other tips?

  2. Keara Littner says

    I actually didn’t know that hard or sticky foods can cause dental crowns to fail and break. I don’t currently have any crowns, but might need one in the next couple of weeks. It’s good to know that I’ll need to pay closer attention to the types of food I eat to keep the crown in good shape.

  3. Douglas Brown says

    I was unaware of the terminology known as Bruxism, but I have that problem currently (just the grinding while asleep part). Luckily for me I don’t have any crowns on my teeth otherwise this could lead to more problems. If I have to get crowns in the future, which I hope that I don’t, I will keep in mind that grinding teeth is a bad thing.

  4. DoloresB says

    It would be frustrating to have dental crowns keep breaking. It’s probably expensive to have a new one put back on. I guess it makes it important to pay attention to what you are eating, because that affects a lot of what might happen to your crown.

  5. Alex Lane says

    Thanks for the information. I am suppose to get my first dental crowns soon and I hope to take good care of them. It sounds like I need to be sure to ask for the porcelain-fused-to-metal crowns. Is there a difference in appearance?

  6. Logan Murphy says

    I think it’s smart to minimize the amount of hard and sticky food you eat, as you advised. Even if we don’t have tooth crowns, I can’t imagine them being very good for our teeth. I just had a crown put in and I would like to make sure I don’t have any future issues with it. Thanks for the good ideas.

  7. Raylin says

    This past summer I got a couple dental crowns, but I think that one of them has chipped and I’ve been trying to find out the reason before I go to the dentist to have it fixed. However, now that I have read this post I think that it has a lot to do with Bruxism. I had no idea that grinding my teeth a lot could have an affect on the crowns. I suppose that it is something that I can work on while I am conscience and a guard might help me at night. What advice to you have for teeth grinders that could help them stop grinding during the day?

  8. Linda Tucker says

    Thanks so much for sharing this information on why dental crowns break. I had no idea that grinding your teeth could cause most crowns to break after a certain amount of time. Right now, I am looking for a dentist to help me with a misshapen tooth, so I will be sure to tell whoever I pick that I might need a mouth guard. After all, I don’t want to pay for a crown, and then have it break shortly afterwards!

  9. Patti Osterberg says

    I didn’t know that grinding your teeth was a common cause of broken dental crowns. I’ve had problems with cracked crowns before, so maybe I grind my teeth. I’ll have to talk to my dentist about getting a mouth guard to prevent this. Do you know how I can tell if I’m grinding my teeth at night?

  10. Olivia Sherwin says

    This is some great information, and I appreciate your point that grinding your teeth can lead to cracked crowns. I’m about to have a couple of crowns installed, but I tend to grind my teeth while I sleep. I’ll definitely talk to my dentist about it to see if there is a solution for this problem. Thanks for the great post!

  11. Tobias Armstrong says

    I went to the dentist when I was younger and found out that I was grinding my teeth my sleep. When it came time to get my implants done, it ended up being a bigger issue than I thought it would be, I’m glad that there are ways to help deal with it now – sounds like I need to make an appointment with my dentist, so thanks for sharing!

  12. Jason Strong says

    My little brother has a crown that keeps breaking and we aren’t sure why. At first we thought it was the way it was being installed, but after the third time of getting it installed, we figured that wasn’t the case. He does eat a lot of candy and sticky things though and I’m willing to bet that is something that is causing it.

  13. Drew says

    Sticky foods has been the culprit whenever my crown has broken. I remember chewing a piece of candy and then all of a sudden feeling like I lost a whole tooth. It’s a good reminder to be more careful for sure. Thanks so much for sharing.

  14. Alex Trodder says

    Your teeth are an integral part of helping you stay healthy. You make a great point about how bruxism can be a major problem for crowns. I’m a terrible bruxor, and my dentist recommended that I get a night guard to help protect my teeth from undo wear and tear at night, just as you mentioned in your article. A night guard can help to protect your natural teeth and any repairs that have been done.

    I love your Article! And this one is especially helpful, so thank you SO much!

  16. Lillian Moore says

    Thanks for the article!! I love how you explain the possible weak materials that could cause breakage in dental crowns. Resin and porcelain are quick to break and fracture. My sister has two crowns and has broken only one of them. I hope I will be able to take better care of them in the future.
