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. Andrew Nalin at our Mount Vernon, WA 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.

October’s here! A month when we celebrate the beauty of fall, the taste of pumpkin spice, the fun of Halloween in Mount Vernon, WA, and the healthy smiles which orthodontic treatment makes possible!

Because October is Orthodontic Health Month, and it’s a great time to talk about how your orthodontist helps you create not just a more beautiful smile, but a healthier one. 

Straight, evenly spaced teeth are the visible benefit of treatment, but there are many health benefits which might not be quite as noticeable. Orthodontic treatment can:

• Help You Prevent Cavities and Gum Disease 

When teeth are crowded or crooked, it’s hard for your toothbrush and floss to reach all of the plaque which builds up on and between your teeth. The bacteria in plaque create acids which start to dissolve tooth enamel. And a very small hole in the enamel surface can grow until it becomes a cavity. 

Plaque and bacteria also irritate the gums. When you can’t remove plaque completely, your gums are at risk for gingivitis. This early stage of gum disease causes redness, tenderness, swelling, and bleeding. Left untreated, gingivitis can develop into more serious gum disease. 

And, over time, plaque hardens and becomes tartar, which needs to be removed by a dental professional.

When your teeth are straight and evenly spaced, brushing and flossing are both easier and more effective, helping you keep your teeth and gums healthy and plaque-free.

• Create a Better Bite

For a healthy bite, your teeth and jaws need to align correctly. The top teeth should slightly overlap the lower teeth, and the ridges of your upper molars should fit smoothly with the grooves of your lower molars. 

Malocclusions, or bad bites, can come in many forms, including overbites, underbites, open bites, cross bites, and overjets. A bad bite is bad for your dental health. Malocclusions can cause tooth grinding, worn enamel, and even cracked teeth. 

And bad bites don’t just affect your teeth. When your bite doesn’t align properly, you might suffer from problems such as headaches, jaw pain, indigestion, and sleep apnea. 

Orthodontic treatment creates a healthy, symmetrical, and pain-free bite.

• Improve Your Self-Confidence

We can’t forget the invisible health benefits of orthodontic treatment! Your smile is a gift which you share with the world. But if you’re hesitating to smile because of self-consciousness about your teeth or bite, orthodontic treatment can make a world of difference.

Dr. Andrew Nalin can help you achieve straighter teeth, a bite which fits together properly, and, when malocclusions affect jaw symmetry, a more balanced facial profile. If you’re concerned about the appearance of your smile, ask Nalin Orthodontics for an orthodontic consultation. Today’s technology can even let you see what your future smile will look like!

Modern orthodontic treatment is more effective and takes less time to complete than ever before. And orthodontics offers patients of all ages more benefits than ever before: 

• New types of braces are less noticeable and more comfortable than older styles. Smaller brackets, brackets which blend with tooth enamel, clear aligners, and lingual braces give you a variety of options to customize your treatment.
• Early orthodontic treatment can guide jaw growth in younger children. 
• Appliances can help with jaw alignment in older children, or, for more serious malocclusions, an orthodontist can coordinate treatment with an oral surgeon.
• Treatment isn’t limited to the teen years. Adults make up a large and growing number of orthodontic patients. 

If you’ve been considering orthodontic treatment, October—or any month!—is a great time to schedule a visit with an orthodontist. An orthodontic evaluation will let you know just what your orthodontist can do to help you create a beautiful and healthy smile.

Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, too. 

Teeth Are Designed for Efficient Eating

Because humans are omnivores, we can eat both meat and plants. That’s why our teeth have different shapes—they’re meant to help us process different types of food. 

• Incisors, our front teeth, have sharpish edges to help cut through meats and other firm foods when we bite.
• Canines, the pointed teeth, help tear food into bite-size portions.
• Premolars are flat topped teeth with two cusps, raised points which help us grind food.
• Molars are the flat-topped teeth in the rear of the mouth. They have four cusps to grind and crush food into a paste-like consistency. 

So: Incisors and canines bite and tear food into smaller pieces, which molars and premolars then crush and grind into a paste. Bite, tear, crush, grind—why all this food aggression? Because that’s the key to healthy digestion. 

Successful digestion begins with chewing. Chewing:

• Starts the process of breaking food down into digestible particles.
• Increases saliva production. Saliva binds food particles so that we can swallow easily.
• Expands the surface area of food particles, which allows the digestive system to extract nutrients more efficiently. 

When biting causes you pain, it can be hard to chew food. Swallowing becomes difficult when food particles are too large, and digestion becomes uncomfortable.

Bite pain can occur when there’s a deep cavity or an injured tooth, but it can also be caused when the teeth and jaws don’t fit together the way that they should. This misalignment is called a malocclusion, or bad bite. And while a malocclusion often makes eating more difficult, it can have further damaging effects as well.

Teeth Are Designed to Be Good Partners

While eating is probably the first thing that comes to mind when we think about dental duties, our teeth also work in coordination with other parts of our bodies. A malocclusion can interfere with these normally smooth interactions, affecting:

• Tooth and Jaw Health

Biting, chewing, and clenching put hundreds of pounds of pressure on our teeth and jaws. A misaligned bite misapplies this pressure, which can lead to damaged and unevenly worn teeth, tooth grinding, headaches, jaw pain, and other problems. 

• Speech

Our teeth work with our tongues and lips to form many of the phonetic sounds which make up speech. Try saying the word “teeth,” and see how your tongue and teeth work together! Misaligned teeth and jaws can affect speech development in children and pronunciation in children and adults.

• Face Shape

Our teeth and jaws help give shape to our faces. Alignment problems can affect facial symmetry and self-confidence.

You Can Help Your Teeth Work Their Best

Daily brushing and flossing, eating a healthy diet, and regular visits to your dentist for exams and cleanings help your teeth perform their many daily duties. But if bite problems are causing troubles with eating, tooth or jaw pain, difficulty speaking, or self-consciousness, it’s time to team up with your orthodontist. 

And just like your everyday dental care, orthodontic treatment works best with your active participation. 

• Make sure your teeth are their cleanest with careful brushing and flossing. You may need to brush and floss more often while you’re in treatment.
• If you wear braces, eat a braces-friendly diet. 
• Wear aligners, bands, or appliances for the hours recommended each day.
• Keep up with your orthodontic visits to keep your treatment on schedule.

Talk to your orthodontist to learn more about how to help your teeth work their best for you—and be ready to share that beautiful, hard-working smile!

You pay attention to what you eat. After all, your oral health depends on it. Without the necessary proteins, vitamins, and minerals in your diet, your teeth and gums will suffer. But did you know it’s a two-way street? Without healthy teeth and a healthy bite, your digestive system can suffer as well.

Because digestion doesn’t start in your stomach—it starts in your mouth! Let’s take a quick look at how the digestive system operates.

• Teeth

The first step in digesting is breaking down foods so your body can extract their nutrients more easily. Healthy teeth are essential here. Incisors and canines tear food into smaller pieces while molars grind these pieces into an easy-to-swallow, paste-like consistency. While we chew, the surface area of the food increases, allowing the digestive enzymes in saliva, the stomach, and the small intestine to work more efficiently.

• Salivary Glands

Saliva production increases when we eat. Digestive enzymes in saliva begin breaking down carbs into sugars, and separating fat molecules. Saliva also contains antimicrobial peptides which are important for oral and gut health.  

• Esophagus

This muscular tube connects the back of the throat to the stomach. As we swallow, muscles in the esophagus contract and relax, an involuntary movement called peristalsis. These contractions push food down into the stomach. Peristalsis also occurs in the stomach and intestines, efficiently moving food through the rest of the digestive system. 

• Stomach

Inside the stomach are gastric acids and enzymes which break food down further to help the small intestine make use of these nutrients in the next stage of digestion.

• Small Intestine

This organ works to reap the benefits of our healthy diets. The small intestine absorbs about 95% of the nutrients from our digested food—carbohydrates, proteins, fat, vitamins, and minerals—and transfers these nutrients to the circulatory system to be used throughout the body. Any remaining food particles travel to the colon, or large intestine.

• Large Intestine

Bacteria in the large intestine help process soluble fiber, which we can’t digest on our own. The large intestine is also where insoluble fiber and anything else undigested are converted to solid waste. 

Now, let’s look at how a malocclusion, or bad bite, can disrupt the digestive process.

In some cases, malocclusions are mild, and require little or no treatment. A more serious malocclusion, though, can impact the way the jaws fit together, making it difficult or impossible for the jaws and teeth to align correctly for efficient and comfortable chewing. What are some possible consequences?

• Uneven bite pressure

With a healthy bite, your teeth and jaws fit together properly to let you get the most out of your meal. When teeth and jaws don’t meet properly, it’s hard to chew food into the paste-like consistency necessary for rest of our system to process it smoothly.

• Reduction in digestive enzymes and peptides

Difficulty chewing means less chewing. Less chewing means less saliva, and your system won’t benefit from the digestive prep work and gut protection which saliva typically provides. 

• Uncomfortable swallowing

Insufficiently chewed food makes peristalsis in the throat and other digestive organs more difficult. Larger pieces of food can become stuck in the esophagus, causing painful swallowing or even choking.

• Higher risk of stomach problems

When food isn’t chewed thoroughly, the stomach has to work harder, and the risk of gastroesophageal reflux increases. Highly acidic gastric juices can back up into the esophagus and mouth, causing heartburn, chest pain, sore throat, and vomiting. 

• Bowel irritation

When food particles are too large, the small intestine must work harder to break them down and to absorb their nutrients. Insufficiently digested food can also upset the bacterial balance in the large intestine. These problems can cause indigestion, constipation, gas, and bloating.

• Changes in nutrition 

Orthodontic problems can also lead to nutritional imbalances even before we start to digest. Soft foods and liquids are often chosen over proteins, fruits, and vegetables when chewing pain is a regular occurrence. While a soft diet is fine for a few days if your mouth is a bit sore following an orthodontic or dental treatment, it can be difficult to get the all the nutrients your body needs when you only eat soft foods.

Orthodontic treatment has many well-known benefits. Straighter teeth. A comfortable, functional bite. Increased self-confidence. Let’s add one more benefit to that list—making sure your digestive system gets off to a great start!

The team at Nalin Orthodontics in Mount Vernon, WA recommends an orthodontic evaluation for children around the age of seven, because finding malocclusions early makes it easier to correct them. But if you’re an adult, don’t settle for painful chewing and an increased risk of digestive problems.
