After the new fixed dentures were placed, the dentures on the opposite side broke?
Hello, doctor.
I recently had three connected prosthetic teeth (crowns and a bridge) installed on the lower right side of my mouth.
However, four days later, one of the prosthetic teeth on the opposite side (left side) broke a piece off.
Could this be due to the uneven distribution of forces on the occlusal surface caused by the newly installed prosthetics on the right side? Is that the reason for the fracture of the left-side prosthetic? Thank you for your response.

The situation you described, where a new dental bridge on one side of your mouth seems to have contributed to the breaking of a tooth on the opposite side, raises several important considerations regarding dental occlusion, the mechanics of dental prosthetics, and the overall health of your oral cavity.
When a new dental bridge is placed, it can indeed alter the way forces are distributed across your teeth when you bite or chew. This is particularly true if the new bridge is not properly aligned with your bite, or if the occlusion (the way your upper and lower teeth come together) is not correctly adjusted. If the new bridge is higher than the adjacent teeth, it can create an uneven distribution of forces, leading to excessive stress on the opposing teeth. This can result in fractures or other damage, especially if those teeth were already compromised or weakened.
In your case, the left-side tooth breaking shortly after the placement of the right-side bridge suggests that there may have been an issue with the occlusion. If the new bridge was not properly adjusted, it could have caused the left-side tooth to bear more force than it was designed to handle, leading to its fracture. This is a common issue in dentistry, where the balance of forces is crucial for maintaining the integrity of dental structures.
Additionally, the material of the dental bridge can also play a role in how forces are transmitted. If the bridge is made of a material that is too rigid or not suited for your bite, it may not absorb shock effectively, leading to increased stress on adjacent teeth. It's essential to use high-quality materials that are appropriate for the specific conditions of your mouth.
Another factor to consider is the health of the remaining teeth and the surrounding bone structure. If the opposing tooth was already weakened due to decay, previous dental work, or periodontal disease, it would be more susceptible to breaking under increased stress. Therefore, a thorough examination of the health of all teeth involved is crucial.
In light of these considerations, it is advisable to return to your dentist for a comprehensive evaluation. They should assess the occlusion and make any necessary adjustments to ensure that your bite is balanced. If the opposing tooth is indeed damaged, your dentist will discuss the best course of action, which may include repairing or replacing the broken tooth.
In summary, while it is possible that the new dental bridge contributed to the breaking of the opposite tooth due to uneven forces, a thorough examination is necessary to determine the exact cause. Proper occlusal adjustment and the use of appropriate materials are critical in preventing such issues in the future. Always communicate openly with your dentist about any discomfort or changes you notice after dental work, as early intervention can often prevent more significant problems down the line.
