Fluoride Varnish: A Valuable Tool for Caries Prevention

Fluoride varnish is one of the most effective ways to prevent caries, yet many dental professionals and patients underestimate its power. If youโ€™re still using fluoride gel or foam, itโ€™s time for an upgrade. Those methods are like listening to eight-track tapes in a world of streaming music.

Fluoride varnish is the gold standard for in-office fluoride application, offering superior efficacy and longer-lasting benefits.


Why Fluoride Varnish is More Effective

One of the biggest advantages of fluoride varnish over traditional foam or gel is its ability to maintain a high fluoride ion concentration for 4โ€“6 hours after application, compared to less than 30 minutes with foam or gel.

The longer fluoride remains in contact with the teeth, the more effective it is for enamel remineralization and protection against decay.


Types of Fluoride Varnish

There are two main types of fluoride varnish:

  • Hydrophilic varnish (creeping varnish):
    Applied only to the facial surfaces, it naturally spreads into occlusal grooves and interproximal spaces, ensuring full coverage with minimal application.
  • Hydrophobic varnish (non-creeping varnish):
    Requires drying the teeth before application and must be manually applied to all surfaces.

Patient-Friendly Advantage:

Hydrophilic fluoride varnishes tend to be more comfortable for patients, as they donโ€™t leave the teeth feeling coated or sticky. This is particularly helpful for patients who resist varnish due to the sensation on their teeth after a hygiene visit.


Overcoming Patient Resistance to Fluoride Varnish

Many patients hesitate to get fluoride varnish because it changes the sensation of freshly cleaned teeth. A helpful analogy to share with patients is:

โ€œImagine going to the hairdresser, getting a perfect blowout, and then right before you leave, your stylist tousles your hair into a mess. That would be annoyingโ€”unless she told you that messing it up would prevent hair loss. Youโ€™d let her do it every time.โ€

Fluoride varnish isnโ€™t about how your teeth feel in the momentโ€”itโ€™s about long-term protection against dental caries.


Increasing Fluoride Varnish Acceptance in Adult Patients

While pediatric fluoride varnish applications are standard, many practices struggle with adult acceptance. In my practice:

  • Over 80% of adult patients receive fluoride varnish at hygiene visits.
  • This uptake took 6 to 18 months of consistent patient education.
  • Many adults initially decline, but after returning with a new cavity, they often request varnish themselves.

Key Tip: Consistently recommend varnish and reinforce its value to gradually increase patient acceptance.


Chlorhexidine Varnish: Another Powerful Tool

For patients already using prescription-strength fluoride toothpaste (like Clinproโ„ข 5000 or MI Pasteยฎ), I use chlorhexidine varnish instead of fluoride varnish.

Benefits of Chlorhexidine Varnish:

  • Suppresses Streptococcus mutans levels for up to four months
  • No staining (unlike chlorhexidine rinses)
  • No bad taste
  • Same easy application as fluoride varnish

By alternating between fluoride varnish and chlorhexidine varnish based on patient needs, we address caries risk from multiple angles.


Fluoride Varnish vs. Silver Diamine Fluoride (SDF)

Many clinicians ask if they should apply both fluoride varnish and SDF at the same visit.

The answer: No.

  • SDF provides high levels of free fluoride ions in saliva.
  • Layering fluoride varnish on top does not add additional benefit.

How to Make Fluoride Varnish Standard in Your Practice

  1. Educate patients on long-term benefits rather than short-term feelings.
  2. Integrate fluoride varnish into hygiene visits so it becomes routine.
  3. Offer chlorhexidine varnish for high-risk patients who already use fluoride at home.
  4. Be patientโ€”consistent conversations lead to long-term acceptance.

Fluoride varnish is one of the simplest, most effective ways to protect enamel and prevent caries. Making it a routine part of hygiene care helps patients maintain healthier smiles for years to come.

Rosie, RDH

I had the pleasure of working with Candy as a dental hygiene consultant over the course of several months, and her impact on both our hygiene department and overall practice was exceptional. Candy is highly knowledgeable, approachable, and genuinely invested in the success of the team. She is an excellent listener who takes the time to understand challenges and provide practical, effective solutions. One of the qualities I appreciated most was her accessibility, she was always available to answer questions, offer guidance, or return a call when needed. Her hands-on approach and commitment to helping our team succeed were evident in every interaction. Candyโ€™s focus extends beyond productivity and practice growth; she truly cares about the people within the practice and works to create a supportive, collaborative environment. As a fellow dental hygienist, it was especially refreshing to work alongside someone who shares a similar philosophy and approach to patient care, team development, and practice success. We view many aspects of dentistry and hygiene through the same lens, which made collaboration seamless and productive. Having the opportunity to work with another hygienist who understands the challenges, opportunities, and importance of our role was invaluable. The hygiene modules she developed were incredibly valuable. They were well organized, easy to follow, and provided clear, actionable guidance. The accompanying handouts and resources gave our team the tools and confidence needed to implement new concepts successfully. Her training materials were practical, relevant, and tailored to the real-world needs of a busy dental practice. Candyโ€™s expertise and dedication to excellence have made a lasting impact on our team. I would highly recommend her to any dental practice looking to strengthen its hygiene department, improve systems, and support the growth and success of its team. She is a true asset to any practice fortunate enough to work with her.

Dr. Justin Elikofer

Our story with IgniteDDS began almost five years ago when my wife and I purchased an established fee-for-service practice. At the time, we promised the team that everything would stay the same. The practice was thriving, and from the outside it seemed clear they had found a successful recipe for success. Our goal wasn't to change itโ€”we simply didn't want to mess it up.

What we discovered was that while everyone wanted the outcome of success, there wasn't alignment around how we achieved it or measured it. Success in room 1 wasn't the same as Room 2. It took us nearly four years to fully understand that because we were doing well. During that time, we also realized we weren't leading as effectively as we could have been. We weren't communicating a clear vision, establishing consistent standards, or implementing clear protocols. Instead, we allowed people to continue doing things their own way. Some team members appreciated that freedom, while others felt frustrated by the lack of consistency and direction.

After four years, we found ourselves at a crossroads. We felt stuck. Morale was low and we weren't sure we could get the practice where we wanted it to go on our own.

As owners who value relationships as much as results, David immediately stood out to us. His personality was authentic, approachable, and trustworthy. He was someone we could see ourselves learning from and building a genuine relationship with. Being local was a bonus, but what really resonated with us was that his vision for practice growth, demonstrated through his own private practice, closely mirrored our own. He had already built the type of practice we wanted to create.

This stood in contrast to many other consultants we spoke with, whose focus seemed to be on PPO models and increasing volume. David's experience aligned with the type of practice we wanted to build: a high-touch, high-end patient experience centered on quality rather than quantity.

The IgniteDDS teamโ€”David, Dawn, and Candyโ€”started by helping us understand where we truly stood. Through discovery, data gathering, and DISC assessments, they helped us identify opportunities for improvement and build a foundation for long-term growth. Rather than jumping straight to solutions, they gave us clarity.

Candy's coaching was instrumental in aligning our hygiene department and our office as a whole with the hygiene department. With her help, we were able to improve the patient experience and new patient process.

We also tackled practical issues that had become major challenges, including an accounts receivable system that was largely out of control. IgniteDDS didn't just point out problemsโ€”they provided systems and processes to solve them.

One of the most valuable aspects of the relationship was having experienced coaches to help us navigate team conflict and leadership challenges. As practice owners, those situations can feel isolating. Having a trusted team to walk through difficult conversations and decisions was invaluable.

Another large impact came through our office managers' work with Dawn. Rather than relying on the doctors to drive every initiative, IgniteDDS empowered our office managers to take ownership of the process and lead from within the organization. They embraced that responsibility wholeheartedly. No challenge was too large or too small. Dawn consistently met them where they were and helped them develop the confidence and skills to lead. The answer was rarely, if ever, "no." Instead, it was, "Let's figure out how."

Today, our practice is more aligned, more accountable, and better equipped to deliver the experience we've always envisioned. We have clearly defined protocols, team agreements, and expectations that simply didn't exist before. Our collections have improved significantly, particularly through implementing systems that helped us address and recover outstanding balances.

If we could offer one piece of advice to another practice owner considering IgniteDDS, it would be to identify the team members who are willing to take ownership and invest in their growth. Share your vision with the IgniteDDS team, trust the process, and allow them to help shape your team into the organization you want to become.

Working with IgniteDDS has been one of the most impactful investments we've made in our practice, our team, and our own growth as leaders. Are things perfect? No. Are we closer? Absolutely, yes!

I was running on empty, and honestly, everyday I thinking of my exit strategy when I met Dr David Rice. As the sole owner of two dental practices, I knew I couldn't continue trying to do everything on my own. Not if I wanted to grow and lead at a higher level. Partnering with IgniteDDS has been, hands down, one of the best investments I've made for both my practices and my team. Just halfway through my first year with IgniteDDS, the impact has already been remarkable. The knowledge, systems, accountability, and leadership development they have provided have transformed the way we operate. Not only have I gained valuable tools and insights as an owner, but my entire team is getting empowered with skills and confidence that are helping us elevate every aspect of our patient experience and practice performance. What sets IgniteDDS apart is the genuine commitment they have to their clients' success. Their guidance is practical, actionable, and tailored to the everyday realities of me running two dental practices. I am incredibly grateful for Dr. David Rice, Dawn, Candy, and the entire IgniteDDS team. Their expertise, continuous encouragement, and unwavering support have made me feel like I am not alone on this journey. If you're a practice owner looking to strengthen your leadership, improve your systems, and create sustainable growth, I cannot recommend IgniteDDS highly enough. The value they provide is truly exceptional, and I am excited to see what the rest of this journey brings.

I had an amazing experience with the IGNITEDDS Coaching program. Especially since I am a new hygienist, everything you guys shared was so helpful. Itโ€™s evident that you guys prioritize each individual team member of a dental office and do everything you can to make the environment and schedule run as smoothly and efficiently as possible. I learned so much about treatment planning, Dentrix, scheduling, teamwork, and overall ways to continue improving as a new grad. I wish every dental office had the opportunity to complete this program.
