Can Toothpaste Repair Tooth Decay?

November 19th, 2025

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. 

Talk to Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying at our Hiawatha, IA office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.

Can You Stop a Cavity Before It Starts?

November 12th, 2025

You’re busy getting ready for your day, and of course you’re starting your day off right by looking after your dental health. A two-minute brushing, some careful flossing, and—wait, is that a white spot on your tooth?

If your mirror reveals a patch of white on your enamel, it could be a symptom of early tooth decay.  Does this mean a cavity is necessarily in your future? Perhaps not, if you act promptly to reverse the damage!

Cavities, after all, don’t suddenly appear in our mouths. Tooth decay is a process, and it begins with a weak area in the enamel that often appears as a white spot on the tooth. These weak spots are known as “incipient cavities,” because they can easily become cavities if left untreated.

Why do these weak spots occur? And how can we repair them? Let’s look at some tooth science.

  • Demineralization

Your tooth enamel is one of the marvels of the human body. Enamel is mostly made of calcium and phosphate ions, minerals which combine to form hydroxyapatite crystals. These crystals create a substance so strong that tooth enamel is the hardest part of the body—harder even than bones.

But it’s not indestructible! If you don’t care for your teeth with regular brushing and flossing, you’re leaving your enamel open to attack.

The bacteria in plaque convert the nutrients they get from the food we eat—especially sugars—into acids. These acids strip away the calcium and phosphate minerals which are the building blocks of our enamel, weakening the surface of the tooth.

Over time, these weak spots get bigger and deeper as bacteria and acids continue to attack the tooth surface. Eventually, cavities form, damaging the enamel surface, and, over time, even reaching into the dentin and the pulp inside the tooth. Once a cavity has formed, you need dental treatment to clean away the decay and repair the tooth structure.

The good news is that, when caught early, it’s possible to rebuild a weak spot in the tooth enamel before a cavity can fully develop.

  • Remineralization

While acids strip minerals from your enamel, your body is also replacing those lost minerals all throughout the day. How does this balancing act take place? With the help of saliva.

The very minerals which acids strip from your enamel are found in saliva. Saliva bathes your teeth with calcium and phosphate ions which, in turn, bond with your enamel to rebuild and restore enamel strength. When missing minerals are replaced like this, it’s called remineralization.

But this careful balance of demineralization/remineralization can become upset. If you neglect brushing and flossing, for example, plaque buildup will increase the amount of acids your teeth are exposed to. This means that your body won’t be able to replace the minerals as quickly as they are stripped away, and the result is a white patch on your tooth where the enamel has lost mineral strength.

If you’re surprised by the appearance of a white spot on your tooth, it’s a good idea to visit our Hiawatha, IA office for a diagnosis. If the spot is caused by an incipient cavity, Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying can provide you with some options to restore your enamel’s strength.

Fluoride toothpastes and fluoride treatments are some of the most efficient ways to remineralize your teeth. Fluoride is attracted to the minerals in your enamel. It bonds with the tooth surface, and, once there, it helps attract the calcium and phosphate ions in your saliva to restore lost minerals and repair weak spots.

But fluoride does more than just restore your tooth’s strength—it improves it! Fluoride ions join with the calcium and phosphate minerals in your teeth to form fluorapatite crystals, which are even larger and stronger than hydroxyapatite crystals.

Early treatment is your best opportunity to reverse the early stages of tooth decay. Keeping up with your brushing and flossing, eating a dental-healthy diet, seeing Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying regularly, and treating incipient cavities promptly will help ensure there are no unwelcome surprises in the mirror—just beautiful, healthy smiles!

National Brush Day

November 5th, 2025

October 31—Halloween. Fourth Thursday in November—Thanksgiving. And, in between these two favorite autumn holidays, we have November 1—National Brush Day!

Okay, okay. Maybe National Brush Day isn’t quite as well-known as Halloween or Thanksgiving, but we take any opportunity to celebrate your dental health. So, let’s celebrate brushing!

After all, brushing is vital for healthy teeth and gums.

  • Brushing is your first line of defense against plaque. Plaque forms all day long. Plaque sticks to your teeth. Plaque is filled with bacteria which produce cavity-causing acids. Brushing regularly means plaque won’t stay on your teeth long enough to cause serious tooth decay.
  • Brushing is also important for your gum health. Angling your brush to carefully clean plaque and bacteria away from your gum line helps prevent gum disease.
  • Tooth decay is the most common chronic disease among children and young adults. The leading cause of tooth loss in adults is gum disease. Good brushing habits help prevent tooth decay and gum disease—a win/win when it comes to your oral health.

To make the most of the time you spend brushing, let’s take a moment to review some basics on National Brush Day.

Are You Brushing Correctly?

  • Big, broad brushstrokes aren’t the answer. Instead, use small up-and-down or circular strokes over each tooth and each tooth surface—outside, inside, and on the flat surfaces of your molars.
  • Because plaque forms all day, you need to keep on top of it. Brushing at least twice a day for two minutes each time is a good general rule. Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying will let you know the best brushing schedule for your individual needs.
  • Brushes are meant to clean, not to scrub. You don’t need a heavy hand for cleaner teeth.
  • Which also means, there’s almost never a good time to brush with a hard-bristled brush. Hard bristles, along with hard brushing, can actually damage your enamel and gum tissue. Stick to a soft-bristled brush for dental TLC.

Are You Taking Care of Your Brush?

  • To clean away bacteria and viruses you might have picked up during the day, wash your hands before brushing and flossing.
  • Shake your brush dry when you’re finished and then let it air dry upright with the handle pointing down. Only use a case for travel, and make sure it has air holes for ventilation. (Bacteria thrive in a wet environment.)
  • If your toothbrush lives in the bathroom, close the toilet seat before flushing to avoid airborne particles.
  • No matter how close you are to your family members or roommates, don’t share your toothbrush. Sharing doesn’t mean caring in this case—it means sharing germs. Your brush should keep a healthy distance from other brushes as well.
  • And no matter how fond you are of your brush, be prepared to replace it often! Most brushes last three to four months at best, because bristles start to fray and can’t clean effectively after several months of use.

It’s no coincidence that National Brush Day comes right after Halloween, the most sugar-filled holiday of them all. So, how can we mark the occasion?

Treat yourself to a new toothbrush! Take a moment to review your brushing habits. If you have young children at home, spend two minutes brushing together to make sure they’re brushing effectively–they might even have some tips for you! Brushing your teeth properly is one of the easiest things you can do to protect your oral health. That’s something to celebrate!

Post-Procedure Care

October 29th, 2025

As with any surgery, post-procedure care is of utmost importance after getting periodontal surgery. Bleeding, pain, swelling, and other sensations are common and should be expected to a degree. This can manifest as small amounts of blood in your saliva, pain after anesthesia wears off, and swelling around the lips and cheeks. However, these symptoms should start improving after a several days.

Below you'll find recommendations from Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying on what you should do to make your post-procedure experience as quick and painless as possible:

Don't smoke - After your surgery you should definitely not smoke. Smoking will inhibit your body's ability to heal the surgical site.

Don't drink alcohol - If you are taking prescription or over-the-counter pain relievers, don't drink alcohol. And it is a good idea in general to avoid alcohol after surgery, since excess alcohol consumption suppresses immune system function and slows the healing process.

Take pain medication as prescribed or an alternative - Pain is to be expected for at least the first week after your procedure. If you choose to take the prescription medication that is prescribed to you, do so as directed. However some patients have found over-the-counter pain medication works for them. You may also consider natural herbs instead of pharmacological solutions. Try turmeric, arnica, or white willow bark (which is what aspirin is derived from, so the same warnings for aspirin apply to white willow bark.)

Eating with your surgical site in mind - It is best to chew on the other side of your mouth for the first several days so as not to irritate the surgical site. Avoid overly cold or hot foods as well. Softer foods like mashed potatoes, oatmeal, and fruit will be more comfortable to chew.

Avoid brushing the surgical site - You can start brushing and flossing your teeth the day after the procedure but avoid the surgical site.

Don't rinse for the first 24 hours - After the first day has passed you can rinse with a mild mouthwash to keep your mouth, dressing, and surgical site clean.

We're here to answer any questions you have after your procedure and will help you as best we can. Pay special attention to any excessive bleeding or discomfort. Contact our Hiawatha, IA office immediately if you have tried addressing the issue on your own but are still having trouble.
