Will Dental Cement Grinding Affect Adjacent Teeth After Crown Placement? - Dentistry

Share to:

When bonding the orthodontic bracket, if the adhesive is in close contact with the adjacent tooth, will grinding down the adhesive later affect the neighboring bonded tooth?


Hello, doctor.
After completing my root canal treatment, I need to have a single crown placed.
I have had a post placed and the adhesive applied, but I noticed that the adhesive has also bonded to the adjacent tooth, making it impossible to insert dental floss between the adhesive and the neighboring tooth.
I would like to ask if the dentist will accidentally grind down the adjacent tooth when reducing the adhesive later on.

Hello: I recommend that you inform the dentist who will be grinding your teeth to first remove the adhesive carefully and to avoid damaging the adjacent teeth.
Thank you!

After undergoing root canal treatment and having a post cemented in place for a crown, it's understandable to have concerns about the potential impact of dental cement on adjacent teeth. Your question regarding whether the grinding of dental cement could affect neighboring teeth is quite pertinent, especially considering the importance of maintaining the integrity of all teeth in the mouth.

To address your concern, when a dentist prepares a tooth for a crown, they often need to adjust the cement or material used to ensure a proper fit and alignment. If the dental cement has inadvertently bonded to adjacent teeth, there is a risk that during the grinding or adjustment process, the dentist might inadvertently affect those neighboring teeth. However, experienced dentists are typically very careful during this process. They will use specialized tools and techniques to minimize any potential damage to adjacent teeth.

Here are some key points to consider regarding your situation:
1. Material Properties: Dental cements are designed to bond strongly to the tooth structure but are also formulated to be somewhat forgiving during adjustments. This means that while the cement is strong, it can be ground down without excessive force that would damage the neighboring teeth.

2. Dentist's Technique: A skilled dentist will be aware of the potential risks involved when grinding down cement that is in contact with adjacent teeth. They will take precautions, such as using a light touch and monitoring the area closely to avoid unnecessary contact with neighboring teeth.

3. Post-Operative Care: After the crown is placed, it’s essential to maintain good oral hygiene. If dental floss cannot be inserted between the crown and adjacent teeth due to excess cement, it’s crucial to inform your dentist. They may need to adjust the area to ensure that you can clean effectively, which is vital for preventing decay and gum disease.

4. Follow-Up Visits: It’s common for dentists to schedule follow-up appointments after crown placement. During these visits, you can discuss any concerns you have about the fit of the crown and the condition of adjacent teeth. If you notice any discomfort or changes in the alignment of your teeth, it’s important to communicate this to your dentist.

5. Long-Term Considerations: If the cement is not properly adjusted, it could lead to plaque accumulation, which might increase the risk of cavities in adjacent teeth. Therefore, ensuring that the area is clean and accessible for flossing is crucial for long-term dental health.

In summary, while there is a potential risk that grinding down dental cement could affect adjacent teeth, a skilled dentist will take the necessary precautions to minimize this risk. It’s essential to maintain open communication with your dental care provider about your concerns and to ensure that your oral hygiene practices are effective. If you have any lingering worries about the fit of your crown or the condition of your adjacent teeth, do not hesitate to reach out to your dentist for further evaluation and assistance.
