Your Hard-Working Teeth

March 4th, 2026

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!

What’s the Function of Functional Appliances?

February 25th, 2026

Whenever we bite down, we’re applying force with our jaw muscles. Functional appliances direct these forces to create healthier tooth and jaw alignment. They’re used to help correct bite problems and to encourage symmetrical jaw growth.

Functional appliances aren’t always necessary. Because every child’s teeth and bite are different, orthodontic treatment at our Denver, NC office is carefully tailored to your child’s individual needs.

  • For the child with minor tooth misalignment, traditional braces or aligners might be all that’s needed.
  • For the child with a minor malocclusion, or bite problem, an orthodontist might use elastics (rubber bands) to bring teeth into healthy alignment.
  • For the child who has a more serious malocclusion, involving both tooth and jaw alignment, an orthodontist might recommend a functional appliance.

A severe Class II malocclusion can be caused when the upper jaw or teeth are positioned too far forward, and/or the lower jaw is too small or positioned too far back. Common Class II malocclusions include:

  • Open bite—the front teeth don’t touch when the back teeth bite down, or the back teeth don’t touch when the front teeth close.
  • Overbite—some overbite is normal. A deep overbite occurs when the upper teeth significantly overlap the lower teeth.
  • Overjet—the upper front teeth protrude further horizontally than they should.

Today’s functional appliances come in a variety of designs to treat Class II malocclusions. They can be fixed or removable. They can be used with or without braces. Some are designed to expand the upper palate to make sure there’s room for all the permanent teeth. What they all do is advance the position of the lower teeth and jaw to create a healthier, more comfortable bite.

Fixed devices are attached to the teeth and meant to be used full-time. These include the Forsus™ device, the Herbst® appliance, and the MARA appliance.

  • Forsus Device

This appliance works with braces. A spring coil rod is most often attached to bands on the first molars on the upper jaw. It’s then connected to the arch wire on the lower jaw. Just like elastics—but more effective!—these spring coil rods provide gentle forward pressure that encourages the lower jaw and teeth forward.  

  • Herbst Appliance

The Herbst appliance also applies forward pressure to the lower jaw using telescoping rods connecting the upper and lower teeth. The rods expand as the mouth opens, and telescope together as it closes, positioning the lower jaw further forward while the upper jaw is held back. The Herbst can be worn alone or with braces, and can also be used to expand the upper palate.

  • MARA Appliance

The MARA (Mandibular Anterior Repositioning Appliance) uses an adjustable “elbow” piece connecting bands on upper and lower molars to guide the lower jaw and teeth forward when the jaw closes.

Removable appliances such as Bionator and Twin Block appliances can also improve Class II malocclusions. They are meant to be worn for a specific number of hours each day, and can be taken out for sports or other activities as needed. Because it’s essential to get all the necessary hours in, removable appliances require commitment!

  • Bionators

A bionator is made of wire and acrylic, and it looks a lot like a retainer. The wire fits around the upper front teeth. It’s attached to a smooth piece of acrylic that sits behind the upper teeth and is shaped to guide the lower jaw forward when biting down. The bionator can also be adjusted to expand the upper palate.

  • Twin Block Appliance

The twin block appliance uses two separate pieces made of wire and smooth acrylic. Both pieces are modeled to fit precisely over the upper and lower arches. The acrylic “blocks” fit over the biting surfaces of the teeth, working together like a 3D puzzle. When your child bites down, the upper blocks slide into place behind the lower blocks, pushing the lower jaw and teeth forward. The top plate can also be adjusted to expand the upper palate if needed.

Because these appliances are best used while a child’s bones are still growing and developing, dentists and orthodontists recommend an orthodontic evaluation by age seven. Early treatment with a functional appliance can help correct serious bite problems before or together with braces. In some cases, functional appliances may reduce the need for headgear or surgery.

Todays’ orthodontic technology has made functional appliances more comfortable and efficient than ever before. Talk to Dr. Todd Hamilton and Dr. Bryan Whitecotton to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

Can Toothpaste Repair Tooth Decay?

February 18th, 2026

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. Todd Hamilton and Dr. Bryan Whitecotton at our Denver, 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.

The Transformation of Valentine's Day

February 11th, 2026

Did you know the actions leading to the beginnings of Valentine's Day were actually centered on the avoidance of war? A Catholic priest named Valentine defied the orders of the Emperor Claudius II and secretly married young men and their brides after the emperor had declared it illegal because only single, young men could be sent to war. Rather than lose potential soldiers to fight his war, Claudius attempted to hoard them by proclaiming marriage illegal.

Valentine continued to marry young couples anyway and, eventually, was put to death for it in 270 AD. Before his death, he sent a letter to a secret love and signed it “From your Valentine”. Nearly 1,800 years later, people are still signing letters and cards in this manner. This year, carry on the tradition started long ago, while adding your own twist. Here are a few suggestions.

Simple and Creative Valentine's Day Ideas

  • Memorialize it with a Photo. Couples often have photos taken around Christmas, but Valentine's Day photos allow you to capitalize on romance. Famous couple Julia Child and her husband, Paul, had their picture taken together every Valentine's Day and included their sense of humor with silly props.
  • Return to Your First Date Location. Even if your first date together was at a local hotdog stand, its sentimental value can make it a fun part of your Valentine's Day agenda. Be creative and make a treasure hunt with clues that lead your partner to the original date location, where you can express your love with flowers or a gift.
  • “From Your Valentine” Messages. Deliver your message in a creative way to make this Valentine's Day stand out from the others. Bake your partner's favorite treat and write a message on it with a tube of icing, or draw a note on the steamed up mirror so it shows up when your partner takes a shower.

Although Valentine's Day is a day to celebrate love, it doesn't have to be a special day only for couples. If you're single, use this special day to shower yourself with love, because you're worth it! After all, the priest Valentine believed so strongly in the sanctity of love that he was willing to risk his life for it. Whether you're in a relationship or single, young or old, romantic or not, Valentine's Day is for you. Happy Valentine’s Day from the orthodontic office of Dr. Todd Hamilton and Dr. Bryan Whitecotton.
