Dental crowns

Dental crowns are permanent tooth covers that are cemented to chipped, cracked or broken teeth to improve their appearance and function.

Can ill-fitting crowns cause teeth to move and change the bite?

Ramin Tabib (New York, NY) on Dec 21, 2011
Ill-fitting crowns can definitely cause teeth to move or the bite to shift and change position. Some people have a high tolerance and an ill-fitting crown won't bother them, although eventually it will cause damage. For some people even a crown that is slightly out of place can wreak havoc.

Yes! They can definitely cause both those things. If a crown does not fit properly it can not only cause shifting of teeth in a horizontal direction but also in a vertical direction as well. What this means is that you can develop spaces, shifting and tipping of teeth, and changes in your bite. A properly fitting crown should not only fit the underlying tooth structure but also have some intimate contact with the adjacent teeth. This means it should provide a nice and easy snap when you floss. If the floss slides through too easily then this can cause the adjacent teeth to shift into that available space. It should also provide equal intensity contact to the opposing tooth when compared to the teeth around it. If the crown is hitting with more intensity or less intensity then once again, the adjacent teeth can be affected. Most often times people will adapt to the changes over time but adaptation does not mean it is a good thing. It means that the teeth, muscles or joint may have compensated for the ill-fitting crown and you can develop problems in other areas.

yes they can. it's important that the crown is adjusted properly.

Your question requires further clarification. If you mean by "fit" how accurately the crown fits to the tooth, then no. If you are using "fit" to describe the manner in which the crown touches the teeth in front of or behind the crown, then possibly. Too much pressure here can cause teeth to shift in that direction or make it difficult to floss. If you are using " fit" to describe the manner in which it touches or chews with the tooth above or below it, then the answer is possibly, though it would likely lead to tooth soreness or tooth aches. It could also cause you to chew in a different spot to compensate for the change in biting forces.

Yes. It can cause decay as well.

Poor fitting crowns can cause bite and other problems.Your bite will change, which may result in food getting stuck, tenderness and eventually decay or a broken tooth. If a recently placed crown does not feel comfortable after a few days, go back to have your dentist check the crown. In many cases, it is something that can be fixed very easily.

Certainly. Generally the problem most noticeable by the patient with a new ill-fitting crown is a tight spot that causes soreness to the tooth. Humans are adaptable creatures, so we will sometimes avoid biting on this new crown to avoid the pain. However, this bite shift can lead to problems with the temporomandibular joint (TMJ). If a new crown is too low, or has open contacts where you floss, the opposing tooth or adjacent teeth will often move to contact the new crown. This can definitely change the way your bite feels. Your dentist should be made aware of your concerns, as an excellent clinician will make your new crown feel like it should. If it doesn't fit right, it should be remade.
