How to Clean Cracks in Fixed Dentures Covered by Gums? - Dentistry

Share to:

If there are cracks at the gum line of a fixed dental prosthesis, how should it be cleaned?


Hello Doctor: My four front teeth are connected as a fixed bridge, and there is a small crack in the gum-covered area of the outermost tooth, which makes it easy for bacteria to accumulate and cause gum inflammation.
One doctor suggested that I redo the bridge as separate units for easier cleaning with dental floss, but the original dentist who placed the bridge said that only one tooth is inflamed and that it doesn't need to be redone; regular cleaning should suffice.
The problem is that I can't reach the gum-covered area with a toothbrush, and dental floss can only clean one side.
Is there a way to address this issue with a water flosser? Or are there other methods?

Hello: It is recommended that you actively clean your teeth using a water flosser, and additionally, you should have X-rays taken at least every six months to check for any periodontal issues.

Cleaning cracks in fixed dentures, especially those that are covered by gums, is a crucial aspect of maintaining oral health. The presence of cracks can indeed trap bacteria, leading to inflammation of the gums and potentially causing further dental issues. Here’s a comprehensive approach to managing this situation.


Understanding the Problem
When fixed dentures, such as bridges, have cracks, they can create pockets where food particles and bacteria can accumulate. This is particularly concerning in areas that are difficult to clean, such as those covered by the gums. If left unchecked, this can lead to gum disease, increased plaque buildup, and even tooth decay in adjacent teeth.


Cleaning Techniques
1. Regular Brushing: While you may find it challenging to brush the area effectively, it’s essential to use a soft-bristled toothbrush to clean the visible parts of the dentures and the surrounding gums. Make sure to angle the brush to reach as much of the denture surface as possible.

2. Dental Floss: Although you mentioned that dental floss can only reach one side, it’s still a valuable tool. Use waxed dental floss, which can slide more easily between the teeth and the denture. Be gentle to avoid damaging the gums.

3. Water Flosser (Oral Irrigator): A water flosser can be particularly effective in cleaning areas that are hard to reach with traditional brushing and flossing. The pulsating water can help dislodge food particles and bacteria from the cracks and gum line. Aim the flosser at the gum line and the cracks to flush out debris.

4. Antimicrobial Mouthwash: Incorporating an antimicrobial mouthwash into your routine can help reduce bacteria in the mouth. Rinse with it after brushing and flossing to provide an additional layer of protection against gum inflammation.

5. Regular Dental Check-ups: It’s crucial to maintain regular visits to your dentist. They can professionally clean the dentures and check for any signs of gum disease or further complications. If the crack is significant, your dentist may recommend repairing or replacing the denture.


Addressing the Cracks
If the crack is causing significant issues, such as persistent inflammation or discomfort, it may be worth discussing the possibility of replacing the fixed denture with a design that allows for easier cleaning. Some dentists suggest using individual crowns instead of a bridge, which can make cleaning more manageable.


Conclusion
In summary, while cleaning cracks in fixed dentures can be challenging, employing a combination of brushing, flossing, using a water flosser, and rinsing with an antimicrobial mouthwash can significantly improve your oral hygiene. Regular dental visits are essential to monitor the health of your gums and the integrity of your dentures. If you continue to experience issues, don’t hesitate to seek a second opinion from a dental specialist who may provide alternative solutions tailored to your needs. Maintaining good oral hygiene is vital not only for the longevity of your dentures but also for your overall dental health.
