Why all the fuss about fluoride? Your dentist recommends it, your toothpaste is formulated with it, most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

1. Fluoride Works!

Fluoride is an attractive option for protecting your teeth—and we mean that literally. Fluoride protects the surface of your teeth by working on a molecular level to attract minerals which strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions which are found in our saliva to restore any minerals which have been lost. This process helps repair any weak spots that might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals.

Want more? Fluoride may interfere with bacterial plaque’s ability to produce acids. Since plaque and its acids are a major cause of gum disease, brushing with a fluoride toothpaste is a great way to help prevent plaque buildup around and below the gum line—buildup that leads to irritated, inflamed, and infected gum tissue.

2. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride is especially important for your child’s dental health. This is because fluoride incorporates with minerals in the adult teeth while they are growing and developing, creating stronger, more cavity-resistant teeth even before they erupt. Most adult teeth have finished forming around age eight, so, if your community doesn’t have fluoridated water, it’s a good idea to discuss other options with your child’s dentist.

And we grown-ups benefit, too! When you drink fluoridated water, you’re increasing the amount of fluoride in your saliva. Just like fluoride toothpaste, saliva bathes your teeth with fluoride ions, strengthening the tooth surface, and helping to neutralize the acids which damage teeth and gums.

3. It’s Easy to Get Fluoride Protection

Most toothpastes are formulated with fluoride, so you’re getting the enamel-strengthening benefits of this mineral whenever you brush—at least twice each day. Since children can’t really grasp the “rinsing” and “spitting” steps of the brushing routine just yet, talk to Dr. Vincent Cardinale and Dr. Chris Moody about how to introduce tiny amounts of fluoride toothpaste to your child’s dental routine. Baby steps!

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride each day. If your community’s water is low in fluoride, we can help you here as well. Prescription fluoride rinses, gels, supplements, and other treatments are available to make sure that your teeth are well-protected, wherever you may live. We will let you know which products are best for you and how often to use them during your next visit to our Naples, FL dental office.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. Check into sealants for both kids and adults for long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter and plaque-reducer that is simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

Creating good dental hygiene habits early in your child’s life is essential to the health of his or her teeth, even when your infant doesn’t have any. By starting now, you can set the foundation for your son or daughter’s oral health later on in life.

When do I start?

The best time to begin brushing your baby’s teeth is before that first tooth ever comes in. Wipe your little one’s gums gently with a soft washcloth soaked in warm water every day. Not only will this help to get rid of bacteria in the mouth, but it will also familiarize your child with a daily brushing routine.

What do I use?

When your child’s teeth begin to emerge, it’s time to switch to a baby toothbrush. Select one with a big grip for your hand and a small head that’s easy to maneuver in your baby’s mouth.

Your little one won’t need toothpaste until he or she is about a year old; and even then, only a small amount is necessary. Apply an amount the size of a grain of rice and move to a pea-sized amount when your infant is about two years old.

By around six years, your child will probably rinse and spit without your help. At this time, you may introduce a child-friendly fluoride mouthwash.

How do I do it?

Until about age five or six, it’s likely your child will still need your help with brushing teeth. Gently scrub over all the teeth and gums, even where teeth have yet to come in. It may be helpful to explain what you are doing and how you are doing it, so your toddler can learn to brush her or his teeth alone.

Paired with regular visits with Dr. Vincent Cardinale and Dr. Chris Moody at our Naples, FL office, proper hygiene habits instilled in your child early on will set up a good foundation for a healthy mouth in the future.

There are lots of ads out there for toothpastes that claim to repair damaged tooth enamel.

Can you treat cavities and tooth decay at home? Well, mostly, no, you can’t.

Can you strengthen your enamel at home? Very possibly—in some circumstances. Let us explain!

Cavities and tooth decay start forming when the enamel on the tooth’s surface breaks down. To discover what causes this breakdown, we need to see how chemistry works with our biology.

Tooth enamel is mainly made from calcium and phosphate ions. These minerals combine to form hydroxyapatite, crystals which make up around 95% of our enamel. Hydroxyapatite crystals are so strong that tooth enamel is the hardest part of our bodies. What can weaken a substance this strong?

Acids. Acidic foods and drinks, as well as acids created by the bacteria in plaque, strip away calcium and phosphate ions in enamel, weakening the surface of the tooth. This is a process called demineralization, and it’s the first stage of tooth decay. Left alone, weak spots will become bigger and deeper until they form cavities.

And tooth enamel, unlike the rest of your body, isn’t living tissue. It can’t regenerate. Once bacteria and acids have created a deep enough cavity, only Dr. Vincent Cardinale and Dr. Chris Moody can repair it by removing decay and filling the tooth.

Wait, this sounds a lot more like “No, you can’t repair your enamel” and much less like “It’s possible to strengthen your enamel.” But we’re not through!

Demineralization doesn’t equal cavities—yet. Careful attention to your habits and your diet can make a difference in whether your enamel continues to weaken or becomes stronger.

Our body’s first defense against demineralization is saliva. Calcium and phosphate ions in saliva bathe the teeth throughout the day, restoring the minerals which have been lost. This is called remineralization. Saliva also helps neutralize acids from the foods we eat. But with a diet heavy in acids, or a lot of plaque buildup, saliva just can’t keep up with the damage.

That’s where “enamel-repair” toothpastes come in. Toothpastes are available that contain hydroxyapatite to restore calcium and phosphates to weakened enamel. But for many of the most common enamel-repair toothpastes, the not-so-secret secret to their effectiveness is fluoride.

Dentists recommend fluoride toothpastes for several very good reasons. Fluoride is attracted to the minerals in tooth enamel and bonds with them. Once bonded, fluoride attracts the calcium and phosphate ions in saliva, helping restore lost minerals to the enamel. Even better, when fluoride bonds with the calcium and phosphate in our enamel, fluorapatite is created. This is a crystal even stronger and more acid-resistant than hydroxyapatite.

If you’re concerned about the strength of your enamel, and especially if you notice any signs of acidic erosion, talk to our Naples, FL dental team right away. Dr. Vincent Cardinale and Dr. Chris Moody can:

• Recommend over-the-counter toothpastes or professional fluoride applications to help reverse early demineralization
• Provide dental bonding, a crown, or a veneer to protect a tooth with serious erosion
• Treat a cavity caused by more advanced tooth decay.

Keeping your enamel healthy at home can take many forms. By careful brushing and flossing to remove plaque, by watching the acids in your diet, by making sure you’re properly hydrated, and by using fluoride toothpaste, you can both reduce the risk of demineralization and help restore weak spots in your tooth enamel.

So, can enamel-repair toothpastes effectively repair your teeth? Yes, they can be effective—if demineralization is in its early stages and if you make them a regular part of your daily dental routine.

So much of parenting is a balancing act. Making sure your child has enough play time and enough nap time. Crafting meals that are both healthy and appealing. Making sure every dental product you use is both effective and safe.

While Dr. Vincent Cardinale and Dr. Chris Moody and our team can’t recommend the perfect bedtime story, or tell you why your child just won’t go for that delicious steamed broccoli, we are more than happy to discuss the very best ways to promote healthy, strong teeth. Should fluoride toothpaste be part of your child’s dental routine? For many good reasons, the answer is yes.

Why Fluoride is Important

Our enamel is the strongest substance in our bodies, with the highest concentration of minerals, but it is not indestructible. The bacteria that live in our mouths create acids which attack our enamel. Weakened enamel leads to cavities. Fluoride is a mineral that makes the enamel surface more resistant to these acids, and can actually help our enamel repair itself in a process called “remineralization.” Fluoride helps prevent cavities and makes teeth stronger, and those are benefits that will last your child a lifetime.

Can There Be Too Much of a Good Thing?

Fluorosis is a condition that can sometimes develop when a child has been exposed to too much fluoride while the adult teeth are developing below the gum line. (Around the age of eight, children’s teeth have finished forming and are not at risk.) Fluorosis is not a disease, and doesn’t harm teeth, but can lead to faint streaks in the enamel. While this streaking is usually white and subtle, it can sometimes be darker and more noticeable. Teeth discolored by fluorosis can be treated cosmetically, but prevention is always the best option.

Finding the Perfect Balance

Talk to us about using fluoride toothpaste when your baby’s first teeth start arriving. If a very young child is at risk for tooth decay, we might recommend early use of fluoride toothpaste. And for these small children, younger than the age of three, a small smear of paste (about the size of a grain of rice) is sufficient if needed. Swallowing fluoride products increases the risk of fluorosis, so make sure to use a very small amount of paste.

Because young children can’t understand the concept of rinsing and spitting, you always want to make sure the amount of toothpaste you use is age-appropriate even as they get older.  From ages three to six, a pea-sized dab of toothpaste is enough. Children should not use fluoride rinses or supplements unless recommended, and should be monitored to make sure they spit out fluoride toothpaste or rinses after brushing.

Most drinking water already has natural levels of fluoride, which normally aren’t a problem. If you are concerned about high fluoride levels in your local water, talk to us. If your water has higher levels of fluoride than normal, you can minimize consumption when your baby is young by breastfeeding, using non-fluoridated water for mixing with formula powder or concentrate, or buying prepared formula. If your child is a toddler, don’t add fluoride rinses or supplements unless they are recommended by a dental or medical professional.
