Fluoride varnish is a quick and easy treatment used to protect teeth and strengthen enamel. This guide will walk you through what fluoride varnish is, how it’s applied, and what you can expect during and after the procedure.
Why do Dentists Recommend Fluoride Treatment?
To realize why dentists recommend fluoride, it’s essential to understand the composition of teeth and how decay, better known as cavities, occurs.
Understanding Tooth Decay
- Tooth Structure: Our teeth have a hard outer layer called enamel and a softer layer underneath called dentin.
- Tooth Decay: When we eat sugary foods, bacteria in our mouth produce acids that can attack the enamel, causing it to weaken and form cavities.
- Demineralization and Remineralization: When acids attack, minerals in the enamel are lost (demineralization). However, our saliva can help repair the enamel by depositing minerals back (remineralization).
How Does Fluoride Help?
Fluoride protects our teeth in several important ways:
- Strengthens Enamel: Fluoride helps rebuild (remineralize) weakened enamel, making it stronger and more resistant to acids. It does so by replacing the fluorapatite crystals with hydroxyapatite crystals.
- Reduces Acid Impact: It makes it harder for acids to damage the enamel.
- Fights Bacteria: Fluoride can reduce the ability of bacteria to produce harmful acids.
- Desensitization: It can help reduce tooth sensitivity.
What Is Fluoride Varnish?
Fluoride varnish is a highly concentrated form of fluoride that is applied to the surface of the teeth. It hardens when it comes into contact with saliva, forming a protective layer over your teeth. This helps prevent tooth decay and can strengthen areas that have started to decay. It has many benefits over other fluoride treatments, making it the most used fluoride treatment. These include:
- Quick Application: The procedure is fast, usually taking just a few minutes.
- Moisture-Friendly: Unlike treatment such as fluoride trays, fluoride varnish doesn’t require your teeth to be completely dry.
- Immediate Eating and Drinking: You can drink liquids and eat soft foods immediately after application.
- Long-Lasting Protection: The varnish continues to protect your teeth even after it’s been applied.
What to Expect During Fluoride Varnish Application
The application process is simple and painless. Here’s a step-by-step look at what you can expect:
Step-by-Step Application
Drying the Teeth:
Although fluoride varnish can set in the presence of moisture, the dental professional will use gauze to lightly dry your teeth, one quadrant at a time.
Applying the Varnish:
Using a small applicator, cotton swab, or applicator, the varnish is applied to the surfaces of your teeth. The professional will start with the facial surfaces, then move to the occlusal (chewing) and lingual (inner) surfaces.
Setting the Varnish:
The varnish hardens quickly when it comes into contact with saliva. You might feel a temporary rough texture on your teeth, and a yellow or white film may be visible. This is normal and will go away after you brush your teeth later.
Aftercare Instructions
To ensure the fluoride varnish works effectively, follow these simple aftercare instructions:
- Avoid Hard Foods: Refrain from eating hard, crunchy foods for 4-6 hours after the application.
- No Brushing or Flossing: Do not brush or floss your teeth for at least 4-6 hours after the varnish has been applied.
- Soft Foods and Liquids: You can eat soft foods and drink liquids immediately after the application.
- Avoid Alcohol: Do not consume alcoholic beverages for at least 4-6 hours post-application.
Conclusion
Fluoride varnish is a quick, effective way to protect your teeth from decay and strengthen enamel. With minimal aftercare and immediate benefits, it’s a convenient option for maintaining dental health. If you have any questions or concerns about fluoride varnish, be sure to discuss them with your dental professional.
