Can Toothpaste Repair Tooth Decay?

February 18th, 2026

It seems like the ads are everywhere these days—repair your enamel and reverse tooth decay with a tube of toothpaste! Are these claims too good to be true? Let’s dive into the science of tooth decay—how decay develops and how (and if!) it can be reversed.

Teeth can stand up to the powerful pressures of biting and chewing because over 95% of our enamel is made up of minerals. Calcium and phosphate ions in our teeth bond to form a crystal structure called hydroxyapatite. Because of the strength of this crystalline design, tooth enamel is the hardest substance in our bodies, even stronger than our bones. 

But bones, like most other parts of our bodies, are living tissue, which means that they can create new cells to replace old or damaged cells. Tooth enamel can’t regenerate new cells to repair itself. This means that when a cavity has made a hole in the tooth, the enamel can’t grow back. And, while enamel structure is very strong, it’s also vulnerable to damage—specifically, damage from acids. 

Our teeth are exposed to acids throughout the day, whether they are acids created by plaque bacteria or the acidic foods and drinks we consume. Acids dissolve mineral bonds, stripping calcium and phosphate minerals from the enamel and leaving weak spots in the tooth surface. This process is called demineralization. Demineralization is the first stage of tooth decay.

The good news? Our bodies are designed with a built-in defense mechanism to prevent demineralization from causing lasting damage. All through the day, saliva helps wash away acids in the mouth and bathes our teeth with new calcium and phosphate ions. These ions bond with the calcium and phosphate in our enamel, restoring enamel strength. This protective repair process is called remineralization. 

Now for the bad news. In the tug of war between demineralization and remineralization, saliva can only do so much. If your diet is heavy with acids, if you don’t brush away acid-producing plaque bacteria regularly, if you eat a lot of the sugars and starches which feed plaque bacteria, the remineralizing effects of saliva can’t keep up with the demineralizing effects of acids.

The first visible sign of demineralization is often a white spot on the tooth where minerals have been stripped from enamel. Studies have shown that enamel-strengthening toothpaste can be effective in this very first stage of tooth decay. Toothpastes which advertise enamel repair generally contain one or more of these ingredients:

  • Calcium Phosphate
  • Hydroxyapatite
  • Fluoride 

Toothpastes with calcium phosphate or hydroxyapatite contain calcium and phosphate minerals, the building blocks of tooth enamel. Studies have suggested that these minerals can replace the calcium and phosphate ions stripped from enamel. These toothpastes may or may not contain fluoride, which is something you should discuss with your dentist before deciding on a specific toothpaste.

Fluoride toothpastes remineralize enamel—and more! Fluoride ions are attracted to the tooth’s surface, and, when fluoride ions join with the calcium and phosphate ions there, they form fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite crystals. And, once bonded with tooth enamel, fluoride attracts the calcium and phosphate ions in saliva to remineralize the teeth more quickly. 

Why consider enamel-repair toothpaste? 

Once enamel is gone, it’s gone for good. If excess demineralization isn’t treated, a weak spot on the tooth surface will continue to erode, growing bigger and deeper until it becomes a hole in the enamel. This is a cavity, and your dentist will need to treat and repair your tooth to prevent the cavity from growing and potentially exposing the tooth’s pulp to bacteria and infection. 

If you wear braces, you want to be especially careful about excess demineralization. Because it can be hard to brush and floss effectively with braces, white spots and discolored patches are a common concern for those with braces, especially on the enamel around brackets.  

Talk to Dr. Todd Hamilton and Dr. Bryan Whitecotton at our Denver, NC office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization when you have braces. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.

The Transformation of Valentine's Day

February 11th, 2026

Did you know the actions leading to the beginnings of Valentine's Day were actually centered on the avoidance of war? A Catholic priest named Valentine defied the orders of the Emperor Claudius II and secretly married young men and their brides after the emperor had declared it illegal because only single, young men could be sent to war. Rather than lose potential soldiers to fight his war, Claudius attempted to hoard them by proclaiming marriage illegal.

Valentine continued to marry young couples anyway and, eventually, was put to death for it in 270 AD. Before his death, he sent a letter to a secret love and signed it “From your Valentine”. Nearly 1,800 years later, people are still signing letters and cards in this manner. This year, carry on the tradition started long ago, while adding your own twist. Here are a few suggestions.

Simple and Creative Valentine's Day Ideas

  • Memorialize it with a Photo. Couples often have photos taken around Christmas, but Valentine's Day photos allow you to capitalize on romance. Famous couple Julia Child and her husband, Paul, had their picture taken together every Valentine's Day and included their sense of humor with silly props.
  • Return to Your First Date Location. Even if your first date together was at a local hotdog stand, its sentimental value can make it a fun part of your Valentine's Day agenda. Be creative and make a treasure hunt with clues that lead your partner to the original date location, where you can express your love with flowers or a gift.
  • “From Your Valentine” Messages. Deliver your message in a creative way to make this Valentine's Day stand out from the others. Bake your partner's favorite treat and write a message on it with a tube of icing, or draw a note on the steamed up mirror so it shows up when your partner takes a shower.

Although Valentine's Day is a day to celebrate love, it doesn't have to be a special day only for couples. If you're single, use this special day to shower yourself with love, because you're worth it! After all, the priest Valentine believed so strongly in the sanctity of love that he was willing to risk his life for it. Whether you're in a relationship or single, young or old, romantic or not, Valentine's Day is for you. Happy Valentine’s Day from the orthodontic office of Dr. Todd Hamilton and Dr. Bryan Whitecotton.

February Is Children’s Dental Health Month

February 4th, 2026

It’s the littlest month of the year, so what better time to think about the dental health of our littlest family members? February is National Children’s Dental Health Month, and we’re here to suggest some of the best dental habits for healthy childhood smiles.

Babies 

  • Even before your baby cuts her first adorable tooth, you can start proactive dental care by gently wiping little gums with a clean, moist gauze pad or soft cloth twice a day. This removes bacteria and food particles and helps prepare your baby for brushing.
  • When that first tooth does appear, or by age one if it hasn’t yet erupted, it’s time to schedule a visit to the dentist. At this first visit, your child’s dentist will check jaw and tooth development and can give expert guidance on teething, brushing, how much and which kind of toothpaste to use, and topics like thumb-sucking and pacifier use.
  • When baby teeth arrive, use a small soft-bristled toothbrush designed to fit comfortably in tiny mouths.
  • Use toothpaste as recommended. Children under the age of three who use paste should use a very small amount, no larger than a grain of rice.
  • Prevent “baby bottle tooth decay”—don’t put your baby to bed with a bottle. This allows the sugars in formula or, when your child is 12 months or older, milk, to bathe the teeth throughout the night. And babies and toddlers never need sugary juices or sodas in those bottles!

Toddlers 

  • Help your child develop a positive relationship with his dental team. Read books or watch videos to help your child learn what to expect. Practice with him by having him open his mouth while you count his teeth. Plan visits when your child isn’t hungry or tired. Be positive yourself—your child will take his cues from you!
  • Schedule regular appointments for exams and cleanings. Your child’s dentist will check tooth and jaw development, look for any signs of decay, and evaluate potential problems such as prolonged thumb sucking or pacifier use. 
  • By age three, children have most or all of their baby teeth. Use a soft bristled brush to clean your child’s teeth twice each day. As she grows, demonstrate how to brush properly. Your dentist and hygienist will have some great ideas on technique!
  • Daily flossing should begin as soon as your child has two teeth which touch. 
  • Around age six, your child may be transitioning to solo brushing and flossing—but your oversight is still needed. Make sure all the surfaces of the teeth, including the tops of new molars, are brushed thoroughly. You might provide a timer or a two-minute song or video to make sure your child spends enough time brushing. Flossing can be tricky for young hands, so you’ll need to help with that task for a few years more.

School-Aged Children

  • Orthodontists and dentists recommend a first visit to the orthodontist by age seven, or earlier if you notice your child has trouble chewing or biting, if the teeth don’t seem to fit together properly, or if you have any concerns about bite and alignment. When potential problems are discovered right away, early intervention can prevent more serious orthodontic issues from developing later. The team at Hamilton and Whitecotton Orthodontics in Denver, NC is happy to answer any questions you might have about early interventions!
  • If your child is beginning orthodontic treatment, you can help make the journey easier: 
    • Keep up with appointments and adjustments—missed appointments can delay your child’s progress. 
    • Braces can make brushing and flossing more difficult, so try special brushes and floss designed just for braces. 
    • If needed, remind your child to wear bands or aligners for the recommended number of hours each day. 
    • Be encouraging! Remind your child that these months in braces or aligners will lead to years of healthy, attractive smiles.
  • Talk to your dentist about sealants. Permanent molars usually erupt between the ages of six and 12. Sealants are thin coatings which protect the chewing surfaces of these molars from food particles and cavity-causing bacteria which would otherwise collect inside grooves in the enamel.
  • Children who play sports and engage in activities with a chance of physical contact should have a well-fitted mouthguard to protect their teeth. Be ready to replace it as often as recommended by Dr. Todd Hamilton and Dr. Bryan Whitecotton or if it’s damaged.
  • Increases in hormones during puberty can lead to puberty gingivitis, and swollen, red, and bleeding gums can be the result. Proactive dental hygiene will prevent gum disease from developing. Make sure your child brushes two minutes, twice a day, and flosses once per day. If symptoms persist, it’s time to see the dentist.
  • A nutritious diet is essential for healthy teeth and gums. Give your child solid nutritional building blocks with a diet rich in proteins, vitamins, and minerals. If your child wears braces, have a variety of appealing, braces-friendly foods on hand. 

Help your child enjoy a future of healthy, confident smiles by working in partnership with your child’s dentist and the orthodontic team at Hamilton and Whitecotton Orthodontics. They are ready every month of the year with advice and expertise to make that healthy dental future a reality!
