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. James Robson at our East Lyme, CT 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.

We get it. You’re working out and could use a boost. It’s 2 a.m. and that essay won’t write itself (darn it). You’re in the middle of a meeting that goes on and on and . . . 

It’s easy to reach for an energy drink when you’re feeling a bit low on, well, energy. These drinks are loaded with caffeine, and, like coffee or tea, can help you feel more alert. But before you pop that top, let’s look at how energy drinks affect your dental health.

• Energy drinks are very acidic.

Acid levels are measured using the pH scale, which ranges from 0 (most acidic) to 14 (most alkaline). Saliva has a normal pH somewhere between 6.2 and 7.6, which helps neutralize any acidic conditions in the mouth and promotes a healthy oral environment. But saliva’s neutralizing effect can be overwhelmed by highly acidic foods and drinks.

Why are higher levels of acids bad for our teeth? Acids strip away minerals like calcium from tooth enamel, the minerals which make enamel the strongest substance in the body. This demineralization weakens the enamel’s protective outer structure and can lead to enamel loss, sensitivity, tooth discoloration, and decay.

Many energy drinks are among the most acidic beverages on the market. Mineral loss in your enamel starts to occur when the pH balance in the mouth falls to 5.5 or less. Lemon juice has a pH between 2 and 3. White vinegar has a pH of 2.5. Energy drinks can range from 1.5 to 3.5 on the pH scale! Studies show that regular consumption of energy drinks greatly increases the risk and severity of dental erosion.

• Most energy drinks are full of sugar.

Sugar is easily metabolized, or broken down, by the body. When our bodies break down food, energy is released. That’s why companies add sugar as well as caffeine to their energy drinks. 

The plaque bacteria which create cavities also use sugars in these drinks as an energy source, converting sugars into acids. Just like acidic foods and drinks, bacterial acids break down the mineral structure in tooth enamel. You might notice small white spots when the enamel starts to erode—and a cavity starts to develop. 

• Energy drinks aren’t just bad for your dental health. 

The temporary burst of energy you get from all the sugar in energy drinks is followed by a sugar crash when blood sugar levels go down again, and you can feel tired, weak, or shaky. 

Even worse, one energy drink might contain three to four times the amount of caffeine found in a cup of coffee. Excess caffeine interferes with healthy sleep. It can cause changes in heart rate, blood pressure, and anxiety levels. 

Children and teens are especially vulnerable to the effects of large amounts of caffeine while their brains and bodies are still developing. That’s why the American Academy of Pediatrics recommend no energy drinks at all for children and teenagers. The FDA suggests that adults should not take in more than 400 milligrams per day of caffeine, while energy drinks can range from around 80 to 400 mg per can. 

If you do have the occasional energy drink, what’s the best way to protect your teeth and gums?

• Don’t linger over your drink. Sipping slowly over time just bathes your teeth and gums in sugar and acids over a longer period. 
• Drink water when you’re done. Water helps wash away sugars and acids, hydrates, and promotes healthy saliva production.
• If the team at Robson Dentistry gives gum a thumbs up, chew a piece of sugarless gum after downing an energy drink to increase saliva flow and help neutralize acids in the mouth. 
• Wait at least 30-60 minutes to brush after finishing an energy drink. Acids in the drink weaken enamel, and brushing immediately can be abrasive to the tooth surface.
• Eat a healthy diet rich in proteins, complex carbs, vitamins, and minerals to feel more energetic.
• Keep up with good dental hygiene. Brush twice each day for two minutes and floss daily, or more often as recommended by Dr. James Robson.

If you notice signs of enamel erosion—sensitivity, front teeth which are becoming transparent or rough around the edges, yellowish discoloration, or white or brown spots on your enamel—it’s time for a talk with Dr. James Robson. When caught early enough, treatment is available which can stop further erosion from harming your teeth.

Braces and aligners help straighten teeth and create a confident, attractive smile. And those visible benefits are amazing! But orthodontic treatment has an even more important purpose than transforming the appearance of your smile—and that’s protecting and improving your oral health.

If you’re ready for orthodontic treatment, you know you can look forward to a future of beaming smiles. You can also look forward to healthier teeth and gums and a more comfortable and functional bite. For some people, orthodontic treatment can make speaking and eating easier, and could even contribute to a better night’s sleep.

How can orthodontic treatment accomplish these goals? Let’s set the record straight!

Protecting Tooth and Gum Health

• Lowering Your Risk of Cavities

Perfectly aligned teeth are considered aesthetically pleasing, but there’s a more practical reason to appreciate straight teeth. Crooked and overlapping teeth make it easier for food particles and plaque to stick in between the teeth and harder for your brush to remove them. Straight teeth allow you to remove cavity-causing plaque more effectively and with less effort.

• Promoting Healthy Gums

When plaque and tartar build up around the gums, the gum tissue becomes irritated, which is the first stage of gum disease. When teeth are straight and evenly spaced, brushing and flossing are easier and more effective, and your gums reap the benefits.

Creating a More Functional and Comfortable Bite

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when you close your mouth. There are different types of bite problems, and these can impact both your oral health and your overall health depending on the type and the severity of the malocclusion. Once a malocclusion is corrected, patients can experience:

• Stronger Teeth and Healthier Gums

Teeth and jaws which don’t fit together properly put extra pressure on your teeth and gums, leading to problems such as worn enamel, cracked teeth, and gum recession. Protect your oral health by creating a well-aligned bite.

• A Pain-Free Bite

Left untreated, malocclusions can cause problems like temporomandibular joint disorder (TMD), headaches, face and neck pain, earaches, limited jaw movement, and painful chewing. Correcting your bite will protect your temporomandibular joint from harm and will relieve the discomfort and pain caused by a malocclusion.

Other Possible Benefits of Treatment

For those with more serious malocclusions, orthodontic treatment might improve daily life in unexpected ways:

• Improved Speech

It takes a lot of coordination to produce different sounds. The lips, the tongue, the alveolar ridge which holds our teeth, the hard and soft palates, parts of the throat, and, yes, the teeth all play a part in creating speech. Some kinds of malocclusions contribute to speech disorders such as lisps, which orthodontic treatment can help correct.

• Improved Digestion

Digestion starts in the mouth, not the stomach! As we chew, we break down our food into particles which are easier for the stomach to digest. If you can’t chew properly because your teeth are misaligned or a bad bite makes it too painful to chew food as thoroughly as you should, you won’t be getting the full nutritional benefits of your healthy diet. Orthodontic treatment helps you bite down painlessly and break down foods easily for better digestion.

• Improved Sleep

Bite problems can sometimes lead to sleepless nights. More serious malocclusions may cause mouth breathing, which, in turn, can affect the quality of your sleep. If you’re having trouble sleeping, a sleep specialist can help you discover the source of your problems. If your troubled sleep is caused by tooth or jaw misalignment, orthodontic treatment might be the solution.

Talk to your dentist to learn about the many options available to align your teeth and jaws for a healthy, attractive smile. Braces or aligners might be all you need to correct a mild malocclusion. Appliances and headgear can influence the growth and position of the jaw if needed. In more severe cases, surgery, together with braces, can create a proportional, healthy bite.

Whether it’s a confident smile, healthier teeth and gums, a functional, comfortable bite, or any of the other benefits orthodontic treatment can bring, talk to the dental team at Robson Dentistry in East Lyme, CT to discover how orthodontic treatment can help you achieve all of your smile goals!

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, as well.

Teeth Are Designed for Healthy Eating and Digestion

Because humans are omnivores, we can eat both meat and plants. That’s why our teeth have different shapes—they’re designed 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 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! 

Chewing is the first step in digestion. Effective 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 you’ve lost teeth or biting causes you pain, it can be hard to chew food as thoroughly as you should. Swallowing can be difficult. Digestion can suffer. In fact, healthy teeth are essential to healthy digestion. 

Teeth Have Other Important Jobs As Well

• Speaking

Our teeth work with our tongues and lips to form many of the phonetic sounds which make up speech. Missing or misaligned teeth can affect speech development in children and pronunciation in children and adults.

• Creating a Healthy Bite

To eat efficiently—and comfortably—we need a healthy bite. If your dentist or orthodontist has diagnosed a malocclusion, it means that your teeth don’t fit together properly because of misaligned teeth and/or jaws. Biting and chewing put hundreds of pounds of pressure on your teeth and jaws, and a bad bite can mean damaged teeth and painful jaw problems. 

• Shaping the Face

Just like our bone structure, our teeth help give shape to our faces. Missing teeth can affect the appearance of chins, lips, and cheeks. Replacing lost teeth with dentures, bridges, or implants (which look and function like natural teeth) can restore facial symmetry.

Teeth Are Only Up to the Job with Your Help

You’re in charge! Daily brushing and flossing, eating a healthy diet, and regular visits to your dentist for exams and cleanings will help make sure your teeth are able to perform their many duties. 

If you’re experiencing tooth pain, if you have concerns about alignment, or if you’ve lost a tooth or teeth, talk to your dentist to learn how to get your teeth back to working their best for you—and be ready to share that beautiful, hard-working smile!
