Tooth grinding and the instability of a dental bridge prosthesis?
Hello, doctor: I have a missing first premolar (for 10 years) and a cracked first molar (which had root canal treatment and restoration 3 years ago).
In order to create a dental bridge, the healthy canine and second premolar were adjusted.
After placing four crowns, I noticed that the canine has slight mobility in the vertical and horizontal directions, but it is not painful (slightly over-erupted).
I have returned for a follow-up appointment, and it was confirmed that the crowns are properly bonded and the gums are healthy.
The mobility seems to be due to the adjustment of the teeth.
Will this movement affect the fit of the entire dental bridge, potentially leading to debonding, cavities, sensitivity, reduced lifespan, or even the need for tooth extraction? It has been 10 days since the crowns were placed, and there is still slight mobility.
What should I do?

Hello: Since it has only been 10 days since the procedure, it is advisable to return to the original clinic and inform the dentist that the dentures feel loose.
Ask if some occlusal adjustments can be made.
If the four-unit bridge is indeed not stable enough (because the supporting first molar has poor structure), consider whether it is necessary to extend it to a five-unit bridge, either backward or forward.

When it comes to dental bridges, stability and proper fit are crucial for long-term success. Your concerns about the slight movement of the canine tooth after the preparation for the dental bridge are valid and warrant careful consideration.
Firstly, it's important to understand that dental bridges rely on the surrounding teeth for support. In your case, the canine and second premolar were prepared to support the bridge, which means they need to be stable and well-aligned. If the canine tooth exhibits any movement, it could potentially compromise the integrity of the entire bridge. This movement might be due to several factors, including the amount of tooth structure that was reduced during preparation, the quality of the bonding material used, or even the occlusion (bite) alignment.
The fact that you have already ruled out issues with the bonding and the health of the gums is a good start. However, the slight rocking of the canine tooth could indicate that the preparation may have altered its stability. If the tooth is not adequately supported, it could lead to complications such as:
1. Loss of Retention: If the supporting tooth is not stable, the bridge may not stay in place as intended. This could lead to the bridge loosening over time, requiring adjustments or even replacement.
2. Increased Risk of Decay: A poorly fitting bridge can create spaces where food particles and plaque can accumulate, increasing the risk of cavities in the supporting teeth.
3. Gum Issues: Movement in the bridge can lead to irritation of the gums, potentially resulting in gum disease if not addressed.
4. Shortened Lifespan of the Bridge: If the bridge is not stable, it may not last as long as it should, necessitating earlier replacement.
Given that you are only ten days post-placement, some initial adjustments may be normal as your mouth adapts to the new dental work. However, if the movement persists, it is crucial to address it promptly. Here are some steps you can take:
- Return to Your Dentist: Schedule a follow-up appointment with your dentist to discuss your concerns. They may need to reassess the fit of the bridge and the stability of the supporting teeth.
- Consider a Bite Adjustment: Sometimes, the occlusion can cause undue stress on certain teeth, leading to movement. A bite adjustment may help alleviate this issue.
- Monitor for Symptoms: Keep an eye out for any signs of pain, increased mobility, or changes in your bite. If you experience any of these symptoms, inform your dentist immediately.
- Seek a Second Opinion: If you feel your concerns are not being adequately addressed, consider seeking a second opinion from another dental professional. They may provide additional insights or alternative solutions.
In summary, while some minor movement can be expected immediately after placement, persistent rocking of the canine tooth is a concern that should not be ignored. It is essential to maintain open communication with your dental provider and ensure that any issues are addressed promptly to prevent further complications. Your oral health is paramount, and taking proactive steps now can save you from more significant problems down the road.
