Can You Repair Your Tooth Enamel?

January 10th, 2024

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. Cody Henriksen 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 Sioux Falls, SD dental team right away. Dr. Cody Henriksen 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.

Troubles with Cementum? Prevent ‘Em!

January 3rd, 2024

Our teeth are a lot more complicated than they look. Beneath that shiny white surface is an entire system of different cell tissues working together to keep each tooth vital and healthy.

  • Enamel, the protective exterior of the crown (the visible part of the tooth), is the strongest substance in the body and the first line of defense against damage to our teeth.
  • Dentin, the hard tissue under the enamel and cementum, has microscopic tubules that connect to the pulp.
  • Pulp, the tissue at the center of the tooth, contains the nerves, blood vessels, and connective tissue that keep the tooth alive.
  • Cementum, composed of connective tissue which forms the protective exterior of the root, also attaches to fibers in the periodontal ligaments which hold the teeth securely in the jaw.

Because cementum is below the gum line, it’s generally safe from the cavity-causing conditions that our enamel is exposed to every day. But there are still potential hazards that we should be aware of.

  • Cementum Erosion

With a name like “cementum,” it’s logical to assume that this is the hardest tissue in the body. Actually, however, that distinction goes to our enamel. And if even our enamel can be damaged by bacteria and plaque, cementum doesn’t stand a chance!

How does cementum come in contact with cavity-causing bacteria? Gums often recede as a natural part of the aging process, leaving part of the root exposed. Gum disease, failure to brush and floss regularly, and heavy-handed brushing can lead to early gum recession. The newly exposed cementum is now exposed to the same conditions, which cause cavities in our enamel. But a root cavity can be trickier to treat and, because the cementum is not as strong as enamel, can progress more quickly. And if a cavity reaches the pulp, a root canal could be necessary.

But the erosion of cementum doesn’t have to result in a cavity to cause discomfort. When cementum is removed, the dentin beneath is exposed. Dentin, you’ll recall, contains tiny tubes that connect to the pulp of the tooth. The result? Conditions such as heat, cold, even an intake of air can cause tooth sensitivity as they stimulate the nerves in the pulp. If your hot coffee or ice cream cone is suddenly causing you pain, let us know. There are treatments, which can reduce tooth sensitivity.

  • Gum Disease (Periodontitis)

In more severe cases of gum disease, the gums pull away from the teeth leaving pockets, which harbor plaque and bacteria. Left untreated, these pockets can become home to infections, which attack and destroy bone structure and connective tissue. Caught early, a treatment called tooth scaling and planing can help. In this type of deep cleaning, your dentist or endodontist will remove plaque and tartar and then smooth the root surface to make it harder for bacteria and plaque to stick. If the gums have receded too far, a gum graft might be necessary to protect the exposed roots.

  • Trauma

The same traumas that can damage teeth above the gum line can result in injuries below it. Chewing on hard objects (ice, hard candies, wooden pencils), bruxism (tooth grinding), and sports injuries or accidents can cause cracks in the cementum. If your root is split or fractured, it might be possible to save your tooth, but sometimes extraction is the best option.

So how do you protect your cementum, hidden as it is under your gum line? The same way you protect the more visible parts of your teeth!

  • Keep to a healthy daily routine of brushing and flossing. This will help prevent gum disease and keep gum recession at bay. Using a soft brush and brushing firmly but gently will remove plaque while protecting both enamel and cementum. If you notice tooth sensitivity, give us a call!
  • Come in to our Sioux Falls, SD office for regular dental exams. The best treatment for gum disease is prevention. When you come in for regular checkups, we are able to discover early signs of gum disease before it becomes a serious problem. If you are suffering from more advanced periodontitis, there are treatments available.
  • Safety first when it comes to your smile. If you chew on hard objects, talk to Dr. Cody Henriksen about how to break the habit. If you grind your teeth, see us for solutions. If you play sports, let us know—often a mouthguard can help protect your teeth from injuries that could otherwise lead to more complex procedures or even tooth loss.

Maintaining your healthy dental habits is a lot like cementum—the foundation of a beautiful smile. Nothing complicated about that!

When to Begin Dental Care for Your Baby

January 3rd, 2024

Children’s oral health differs from the needs of adults in many ways. It’s vital for you to understand what your child needs to keep his or her teeth healthy. Dr. Cody Henriksen and our team are here to answer your questions to set you and your little one up for success.

In-home dental care should start as soon as your baby show signs of developing that first tooth. At around age one or two, bring your son or daughter to our Sioux Falls, SD office. Dr. Cody Henriksen will examine your child’s tooth development and gum health.

The initial appointment will focus on getting your youngster familiar with our office and comfortable with our staff. We will go over several general matters during that first visit:

  • Inspect for signs of decay or other tooth or gum problems
  • Check for gum disease or cavities
  • Examine your child’s bite and possible misalignment
  • Clean the teeth, and apply fluoride if your child is old enough
  • Talk with parents about proper oral health
  • Give you tips for brushing and flossing your little one’s teeth
  • Answer any questions you may have about caring for your son or daughter’s teeth

Once your child is old enough for the first dental visit, you should schedule regular cleanings every six months. Call our Sioux Falls, SD location if you have any conflicts or questions.

Toothbrush Arts and Crafts

December 28th, 2023

When you replace your old toothbrush every three or four months with a new model, you accomplish three things:

  • You keep your teeth cleaner (frayed brushes don’t clean as well)
  • You protect your gums (you won’t be scrubbing harder to get your teeth clean)
  • You add another toothbrush to your growing collection of used brushes

If creative recycling is one of your talents, you might have already discovered how handy repurposed brushes are for cleaning delicate or hard-to-reach spaces around the house. But those old brushes don’t have to spend their entire existence cleaning! Here are some ideas from Dr. Cody Henriksen to give a new, artistic life to your old, uninspired toothbrush.

  • Splatter Painting

As your bathroom mirror can confirm, toothbrushes are great for splattering. Why not put those bristles to creative use by adding color bursts to canvas, wooden picture frames or boxes, fabric, cards, gift wrap and more? Just dip the tips of the bristles into the paint, point them toward your surface, and brush your finger over the head. For more formal effects, splatter paint over your favorite stencils on paper or fabric. Or work your magic by splattering around a stencil for a dramatic silhouette.

  • Children’s Painting

Your child might find it great fun to use an old toothbrush to create new works of art. The easy-to-grip handle and wide bristles are perfect for painting those first masterpieces. Splatter painting is also a wonderful art activity for children—but be prepared for some clean-up!

Texturizing Clay Pieces

Whether you work in potter’s clay, polymer clay, or Play-Doh, an old toothbrush can provide any number of interesting textures to your piece. Press the bristles into the clay for a sophisticated stippled background, or brush long gentle strokes for a striated effect.

  • Carpentry

Wood glue creates strong bonds when you are joining edges, mitering corners, or fitting mortise and tenon joints. It also creates a sticky mess when you use your fingers, a wood or plastic spreader, or one of your good paint brushes. For any gluing jobs or joinery, try a toothbrush for greater control and easy application.

  • Jewelry Making

If you work with jewelry pieces, you know that sometimes there are nooks and crannies that are almost impossible to clean or polish. Try a gentle brush with an old toothbrush and the recommended polish for your piece—but do keep brushes away from the delicate surface of pearls. And for the boldly creative, why not use your toothbrush itself as jewelry? There are online instructions out there for transforming that old brush into a colorful bangle bracelet.

In turns out that there’s a second career waiting for your toothbrush after all! Make sure to clean your toothbrushes thoroughly before using them in another role. After that, let your creativity run wild—including your creative recycling! It’s just another way you are crafting a more beautiful environment for all of us.
