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. Ryan Hinckley at our High Point or Greensboro, 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.

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 Berky Hinckley Orthodontics in High Point or Greensboro, NC 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. Talk to Dr. Ryan Hinckley to learn how orthodontic treatment can give you an attractive, functional smile. Your healthy smile—and your healthy body—will thank you!

It's a moment many of our patients have experienced. One second you're chewing on a piece of gum, then suddenly you forget to keep chewing and swallow the entire rubbery gob whole! It's at this point you remember your mother warning you as a child that if you swallow gum it will stake a claim and take up residency in your belly for seven years. Dr. Ryan Hinckley and our team at Berky Hinckley Orthodontics hate to take all the fun out of the mystery, but the truth is that chewing gum, when swallowed, will enter your stomach and move through your digestive system just like any other piece of food. So, if you ever accidentally swallow a piece of gum, there is no need to worry!

That being said, it's important to know that gum does not have any dietary benefits, so while it’s not exactly harmful to swallow, you still want to avoid swallowing it. If you are an avid gum-chewer, we encourage you to chew sugarless gum, especially if you are wearing braces, because gum with sugar can lead to cavities. Sugarless gum still has the same amount of flavor, but has fewer cavity-causing ingredients. In fact, many brands contain an additive called xylitol, a natural sweetener known to fight cavity-causing bacteria. Xylitol is also known to increase salivary flow as it rinses away plaque and acid.

The fact is, when the bacterium in your mouth breaks down sugar, what’s left behind is acid. This acid eats away at the enamel coating of your teeth, causing holes that we call cavities. Cavities can lead to other long-term mouth problems if they are not treated in time, so it is best to try and avoid overexposing your teeth to too many harmful substances!

If you have any questions about chewing gum, please contact our office. Happy (sugar-free) gum chewing!

By now, everyone knows that smoking is bad for you. But the truth is its broad-reaching health effects are not all known by everyone. This is especially true of oral health. Smoking can have serious repercussions in this regard. To give you a better idea of how smoking can affect your oral health, Dr. Ryan Hinckley and our team have listed some issues that can arise.

Oral Cancer

Oral cancer can have steep ramifications for anyone that gets it. Surgery can be required to eliminate the cancer before it spreads to more vital parts of your body. Any type of cancer is about the worst health effect you can get, and this especially holds true to the affects that smoking has on your mouth. The type of mouth surgery required with oral cancer can leave your face deconstructed in certain areas, and it is all due to smoking or use of other tobacco products.

Tooth Discoloration and Bad Breath

At the very least, it is fair to say that as a smoker you will often have bad breath, and while you may try to cover it up with gum or mints, tooth discoloration is a whole other story. The chemicals and substances in cigarettes stick to your teeth staining them brown and yellow colors that are increasingly difficult to disguise.

Gum Disease and Loss of Bone

Another effect of smoking is the increased risk of gum disease. Your gums may start to recede, which can eventually lead to the loss of teeth. Smoking can also increase bone loss and density in your jaw which is vital to the health of your mouth. Gum disease and bone loss are two signs that smoking is definitely bad for your mouth.

When it comes to the health of your mouth, the question is not whether smoking affects your health, it's how does it affect your health and to what degree. If for no other reason than because smoking involves your mouth as its entry point, it is safe to say that it can have long-lasting and detrimental consequences on your oral health.
