Can Improper Teeth Cleaning Cause Loose Dental Crowns? - Dentistry

A fixed dental prosthesis became loose due to dental cleaning?


Hello: I have a fixed upper denture with eight teeth connected, which has been in place for about 23 years.
Since my original dentist has retired, I changed clinics for a dental cleaning.
About a week after the cleaning, I felt that the denture was loosening.
Could improper dental cleaning cause the denture to become loose? Can a loose denture be reattached?

Dear Miss Qin Qin: It is recommended to return for an examination to determine the cause of the looseness of the dentures.
If the periodontal condition of the supporting teeth is still acceptable, the dental bridge can be removed and re-cemented.

Improper teeth cleaning can indeed contribute to issues with dental crowns, including the loosening of crowns over time. When dental crowns are placed, they are typically cemented onto the underlying tooth structure. This bond is crucial for the stability and longevity of the crown. If proper oral hygiene is not maintained, plaque and tartar can build up around the crown margins, leading to gum disease or decay of the underlying tooth. This can weaken the bond between the crown and the tooth, potentially resulting in a loose crown.

In your case, if you have noticed a feeling of looseness in your dental crowns after a dental cleaning, it is essential to consider a few factors. First, the cleaning process itself should not directly cause crowns to loosen if they were properly placed and the surrounding tissues are healthy. However, if the cleaning was aggressive or if there was significant buildup of tartar that was removed, it might have exposed areas that were previously protected, leading to sensitivity or a feeling of looseness.

Additionally, if there is any underlying gum disease or decay that was not addressed prior to the cleaning, this could also contribute to the feeling of looseness. The gums play a significant role in supporting dental crowns, and any inflammation or recession can affect the stability of the crown.

Regarding your question about whether a loose crown can be re-cemented, the answer is generally yes, but it depends on the condition of both the crown and the underlying tooth. If the crown is intact and there is no significant decay or damage to the tooth structure, a dentist can usually clean the crown and the tooth, then re-cement it. However, if there is decay or if the crown is damaged, further treatment may be necessary, which could include a new crown or additional restorative work.

To prevent future issues with your crowns, it is crucial to maintain excellent oral hygiene. This includes brushing twice a day with fluoride toothpaste, flossing daily, and using an antibacterial mouthwash to help reduce plaque buildup. Additionally, regular dental check-ups and cleanings are essential to monitor the health of your crowns and the surrounding tissues.

If you are experiencing discomfort or a persistent feeling of looseness, it is advisable to schedule an appointment with your dentist as soon as possible. They can assess the situation, determine the cause of the looseness, and recommend the appropriate treatment. Ignoring the issue could lead to more significant problems down the line, including the potential need for more extensive dental work.

In summary, while improper cleaning can contribute to the loosening of dental crowns, it is essential to evaluate the overall health of your teeth and gums. Regular dental care and proper hygiene practices are vital in maintaining the integrity of your dental restorations. If you have concerns about your crowns, do not hesitate to seek professional advice.
