Effective Strategies to Combat Plaque and Prevent Cavities

The issues of dental cleaning and dental plaque?

Hello Dr.
Tseng,
I have been experiencing dental issues since middle school, where I have been getting check-ups and cleanings every six months.
However, it feels like I am constantly getting cavities filled and then developing new ones.
In recent years, I have researched dental care and brushing techniques to eliminate the risk of further cavities.

I would like to ask you, Dr.
Tseng, about my current oral hygiene routine.
I am using the Bass technique for brushing, along with disclosing agents, a single tuft toothbrush, and dental floss.
This method effectively cleans most of the dental plaque.
However, around the areas of my filled teeth, there seems to be a ring of plaque that I cannot remove, which appears slightly pink (a thin ring that won’t come off no matter how much I brush).
Is this amount of plaque still a risk for developing cavities? Additionally, how can I remove it?
Furthermore, in areas where my teeth are not very aligned, it is difficult to remove plaque even with dental floss and a single tuft toothbrush.
What method should I use to clean those areas? Thank you for your response.

Hello, thank you for your inquiry.
I would like to respond to your question and provide the following suggestions:
There are two main types of materials used for dental fillings: resin and amalgam.
While resin is aesthetically pleasing, its hardness may not be as good as that of amalgam.
However, any filling material will have tiny gaps at the junction with the tooth, which can harbor plaque.
It is important to thoroughly remove plaque from these junctions when brushing or using dental floss to prevent the filling material from deteriorating due to plaque accumulation.
Additionally, misaligned teeth can affect oral hygiene effectiveness.
If misalignment prevents proper oral care, orthodontic treatment should be considered to align the teeth for better cleaning.
Dental floss and single-tuft toothbrushes are designed for cleaning between teeth and should be used gently.
When using dental floss, it should be placed against the tooth surface and gently moved down into the gum line to effectively remove plaque.
Wishing you peace and happiness!

More Info

To effectively combat plaque and prevent cavities, it’s essential to adopt a comprehensive oral hygiene routine that goes beyond just brushing and flossing. Your current regimen, which includes the Bass brushing technique, disclosing agents, a single tuft toothbrush, and dental floss, is a solid foundation. However, there are additional strategies and considerations that can enhance your oral health and help prevent cavities.

Understanding Plaque and Cavities
Plaque is a sticky film of bacteria that forms on your teeth. If not removed through proper oral hygiene, it can harden into tartar, which can lead to cavities and gum disease. Cavities occur when the acids produced by bacteria in plaque erode the enamel of your teeth. The presence of plaque around dental restorations (fillings) can indeed pose a risk for new cavities, especially if it is not effectively removed.

Addressing Residual Plaque
You mentioned that you notice a ring of plaque around your fillings that appears pink when using a disclosing agent. This indicates that bacteria are still present in that area. While a small amount of plaque may not immediately lead to cavities, it can create an environment conducive to decay, especially near existing restorations. Here are some strategies to tackle this issue:
1. Improved Brushing Technique: Ensure that you are using the Bass technique correctly. This involves placing the toothbrush at a 45-degree angle to the gum line and using gentle, circular motions to dislodge plaque. Spend at least two minutes brushing, focusing on all surfaces of your teeth.

2. Use of Interdental Cleaners: If traditional dental floss is challenging to use effectively, consider alternatives such as interdental brushes or soft picks. These tools can be more effective in cleaning between teeth and around fillings, especially in tight spaces or irregularly shaped areas.

3. Regular Dental Visits: Continue with your biannual dental check-ups and cleanings. Your dentist can provide professional cleanings that remove tartar and plaque that regular brushing may miss. They can also evaluate the condition of your fillings and suggest replacements if necessary.

4. Fluoride Treatments: Ask your dentist about fluoride treatments. Fluoride can help remineralize enamel and make it more resistant to decay. Additionally, using a fluoride toothpaste can provide extra protection.

5. Dietary Considerations: Limit sugary snacks and beverages, as they contribute to plaque formation. Instead, focus on a balanced diet rich in fruits, vegetables, and dairy products, which can help strengthen your teeth.

6. Mouth Rinses: Consider using an antimicrobial mouth rinse that can help reduce plaque and bacteria in your mouth. Look for products that contain chlorhexidine or cetylpyridinium chloride.

7. Sealants: If you are particularly prone to cavities, discuss with your dentist the possibility of dental sealants. These are protective coatings applied to the chewing surfaces of back teeth, which can help prevent decay.

Addressing Misaligned Teeth
For areas where your teeth are not aligned, plaque accumulation can be more challenging. Here are some additional tips:
- Orthodontic Consultation: If misalignment is significant, consider consulting an orthodontist. They can provide options for braces or aligners that can improve the alignment of your teeth, making them easier to clean.

- Customized Oral Hygiene Tools: Some companies offer toothbrushes and flossers designed specifically for individuals with braces or misaligned teeth. These tools can help you reach difficult areas more effectively.

Conclusion
Maintaining optimal oral hygiene is a multifaceted approach that requires diligence and regular care. By enhancing your current routine with these strategies, you can significantly reduce the risk of cavities and improve your overall dental health. If you continue to struggle with plaque accumulation, it may be beneficial to work closely with your dentist to develop a personalized plan that addresses your specific needs. Remember, prevention is key, and proactive measures can lead to a healthier smile.
