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 Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani 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 Dallas dental team right away. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani 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.

In the eyes of most parents, nothing is cuter than their baby’s smile. Did you know your little one’s smile (that is, his or her oral health) actually plays a huge role in determining the child’s overall well-being? In order to keep your youngster healthy and smiling, you need to know when and how to take care of those tiny teeth.

Baby teeth aren’t just temporaries that will fall out eventually. They help your baby chew and talk, and they reserve space in the jaw for permanent teeth later on. Since they’re so important, the right time to start dental care is only a few days after your infant is born.

Take a soft, wet washcloth or piece of gauze and gently wipe your baby’s gums. The earlier you begin, the more accustomed your child will become to a daily dental hygiene routine.

Babies that are put to bed with a bottle may be at greater risk for developing cavities. Milk, juice, and any other drinks that contain sugar instigate tooth decay while the child sleeps.

If your baby must go to bed with something, a bottle of water is the healthiest option. Remember to wipe your little one’s gums after each feeding, whether it’s formula from a bottle or breast milk.

As soon as your infant’s first tooth comes in, it’s time to start brushing! Twice a day, take a small amount of toothpaste (about the size of a grain of rice) and brush your son or daughter’s teeth gently in circular motions. As soon as your toddler has multiple teeth that touch one another, floss up and down the sides of the teeth to remove any plaque between them or below the gumline.

Babies’ teeth are prone to cavities and gingivitis, so you’ll want to be on the lookout for telltale signs. Check regularly for red, swollen gums, because this may be an indication of developing gum disease. Discoloration, white spots, or small pits in the teeth can signal a forming cavity.

As long as you follow these simple guidelines and schedule regular dental checkups with Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani at our Dallas office, you can help to ensure your baby has a healthy mouth. There is nothing more rewarding than seeing your happy baby’s healthy smile.

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 Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani 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.

Talk to us during your visit to our Dallas office about protecting your child’s teeth. We are happy to help you find just the right amount of fluoride to keep young smiles stronger and more resistant to tooth decay. Healthy teeth in a beautiful smile—that’s a perfect balance!

Fluoride has been one of the great game-changers in children’s dental health. Drinking fluoridated water. Using fluoride toothpaste. Scheduling fluoride treatments. All of these child-friendly dental habits help prevent cavities and strengthen tooth enamel.

And we adults enjoy the benefits of fluoride as well. Drinking fluoridated water. Using fluoride toothpaste. If only we hadn’t outgrown fluoride treatments… or have we? Time to have an adult conversation about fluoride treatments!

• To Start, Some Dental Chemistry

The enamel in our teeth is largely made of calcium and phosphate ions. These elements combine to form hydroxyapatite, the mineral crystals that make teeth and bones so hard and strong. But enamel isn’t indestructible. The oral bacteria in plaque create acids that cause demineralization, stripping away calcium and phosphate ions. This leaves the tooth surface weakened and vulnerable to decay.

Our bodies have a way of compensating for demineralization. Saliva is filled with calcium and phosphate ions that restore lost minerals. This balancing act goes on every day. When conditions in the mouth are too acidic, however, remineralization can’t take place as effectively. Here’s where fluoride is so beneficial.

• Why Fluoride?

First, because fluoride helps remineralize. Fluoride works on the surface of the tooth to attract the calcium and phosphate ions in our saliva, restoring them to our teeth. Even better, it joins with these ions to create fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite. This means your teeth are not only remineralized, but stronger than they were originally!

• Why Adult Fluoride Treatments?

While fluoridated water and fluoride toothpaste might be all you need for strong enamel, there are several conditions that make fluoride treatments a good addition to your preventive care at our Dallas office.

• Problems with dental hygiene. Consider fluoride treatment if you have trouble brushing and flossing, if you wear braces, or if there’s any other reason that makes daily cleaning more difficult.
• Exposed roots. Gums often recede as we age, and can pull away from the teeth even further with added factors like gum disease, harsh brushing habits, teeth grinding, or smoking. As gums recede, parts of the tooth roots are exposed. Because roots are covered with cementum instead of the much harder enamel, they are more vulnerable to decay.
• Dry mouth. Medical conditions, medications, and aging can cause a decrease in saliva production. Because saliva helps wash away food particles and bacteria, bathes the teeth with minerals that strengthen enamel, and neutralizes acids, less saliva can equal more cavities.
• Our individual biology. Some of us are born with weaker tooth enamel, and so are more at risk for cavities—even with great brushing and flossing habits.

In all of these cases, fluoride treatments can provide the extra protection you might need for stronger tooth enamel and improved dental health.

• Treatments Are an Easy Addition to Your Dental Appointment

Regular fluoride treatments are neither complicated nor time-consuming. Fluoride can be administered as a varnish, a gel, a rinse, or a foam. It can be applied with a brush, a swab, as a mouthwash, or in a tray. After application, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will let you know if any follow up instructions, such as avoiding food and drink for 30 minutes after treatment, are necessary. That’s all there is to it. Protection lasts for months, and your dentist can let you know when a re-application is needed.

You’re doing the right thing by using a fluoride toothpaste and keeping up with your dental exams and cleanings. Ask Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani if a fluoride treatment is something that could strengthen your teeth and help prevent decay—it could be a game-changer for your dental health!
