The Twin Block Appliance

September 25th, 2025

Orthodontic treatment involves a lot more than just straightening your teeth. For a healthy smile, your bite must be healthy as well! This means that the upper and lower jaws need to fit together properly and comfortably.

If your bite is out of alignment because of jaw misalignment, orthodontic treatment can help correct the shape and position of your jaws with devices called functional appliances. These appliances are most often used for young patients whose bones are still growing, and are designed to treat malocclusions, or bite problems.

Common malocclusions such as overbites and overjets can occur when the upper teeth protrude further than they should, or the lower jaw is positioned too far back, or both. The Twin Block appliance can be used in such cases to help move your lower jaw and teeth into alignment with your upper jaw.

Why “Twin”? Because the Twin Block appliance is two separate pieces, each made of wire and smooth acrylic. Both pieces are crafted to fit precisely over your upper and lower arches and can be adjusted as your treatment progresses. The top plate can also be adjusted, if necessary, to widen the upper palate.

Why “Block”? Acrylic blocks cover the biting surfaces of several of your upper and lower teeth. These blocks fit together like a 3D puzzle. When you bite down, the upper blocks interlock with the lower blocks, pushing the lower blocks forward just a bit before you can bite down completely. Over time, bit by bit (and bite by bite), the Twin Block appliance advances your lower jaw and teeth to create a balanced, comfortable bite.

For the quickest and best results, you should wear your Twin Block appliance as directed. It’s made to be worn comfortably while you sleep, eat, and otherwise go about your day. (It’s a good idea to check with our Greensboro, NC orthodontic team to see about removing it when you’re active, especially for swimming and contact sports.) When it’s time to brush, the Twin Block appliance is removable. This means that you can clean your teeth and your appliance easily.

And, while it’s made to work hard for you, it’s not indestructible. Don’t expose your appliance to heat or hot water, as the plastic may warp. Use the cleaning methods we recommend. Finally, when your appliance is out of your mouth, keep it in its case! You don’t want your appliance to end up carefully wrapped in a napkin in the nearby recycling bin. Or, even worse, in your dog’s mouth instead of yours.

The Twin Block appliance might fit together like a puzzle, but there’s nothing puzzling about how to achieve your best and fastest results. Your success really depends on you. Follow Drs. Mark and James Kaley and our team’s advice, wear your appliance as directed, and you’ll be on your way to a healthy, comfortable bite and an attractive, confident smile!

Planning Your Vegetarian Diet with Your Oral Health in Mind

September 18th, 2025

If you’ve been following a vegetarian or vegan diet, you know that there’s much more to living a healthy life than simply avoiding meat products. Making sure your diet includes enough protein, as well as any nutrients that are primarily available in animal products, takes planning, and there’s no one-menu-fits-all solution.

Why? Because there’s no one menu that will suit all vegetarians. Specific vegetarian diets can allow for many different options:

  • Vegan—a plant-based diet which excludes meat, fish, dairy, and egg products
  • Ovo-vegetarian—includes eggs as a dietary option, but no dairy
  • Lacto-vegetarian— includes dairy as a dietary option, but no eggs
  • Lacto-ovo-vegetarian—a meat-free diet which allows both dairy products and eggs

If you are a pescatarian, who eats fish on occasion, or a flexitarian, who sometimes includes meat in a meal, your menu options are even broader.

So let’s look at the big picture—a healthy vegetarian diet is really more concerned with the foods you do eat for nutrition rather than the foods you don’t. You can create a meal plan rich in all your essential nutrients with a little research, no matter which type of vegetarian diet is your go-to choice.

And while you’re constructing your ideal menu guidelines, don’t forget about your dental nutrition!

In terms of keeping your teeth and gums their healthiest, what important vitamins and minerals are often missing from vegetarian and vegan diets? Let’s look at three of them.

  • Calcium

Calcium is essential for maintaining strong bones and tooth enamel. Without enough calcium, a weakened jawbone leads to loose, and even lost, teeth. The acids in our food and the acids created by oral bacteria also weaken the minerals in enamel, including calcium. These weak spots can eventually become cavities. A diet rich in calcium not only supports the bones holding our teeth, but can even help repair, or remineralize, enamel which has been weakened by acidic erosion.

For vegetarians who include dairy in their diets, dairy products are a great way to include calcium. Milk, cheese, and yogurt are traditional and rich sources of this mineral.

For vegans, it’s a bit more challenging, but still doable! Non-dairy foods providing calcium include dark green vegetables (kale, broccoli, spinach), certain types of tofu, and fortified cereals, juices, and non-dairy milks.

  • Vitamin D

Now you’re ready to put that calcium to work by making sure you have enough vitamin D in your diet. Vitamin D not only helps keep our bones healthy, it also enables our bodies to absorb calcium. Bonus—it’s been linked to better gum health in several studies.

So how to get more vitamin D? If you eat dairy, most dairy products have been fortified with vitamin D. If eggs are a part of your diet, egg yolks are a great source. Pescatarians can enjoy the benefits of vitamin D from fatty fish such as tuna and salmon.

Because we get most of our vitamin D from sun exposure or foods derived from animals, plant-based foods are not a practical way to obtain the vitamin D you need. But, just as non-vegetarians can get plentiful vitamin D from fortified dairy products, vegans also have options. Try adding cereals, juices, and non-dairy milks fortified with this essential nutrient to your diet, or take a vegan vitamin D supplement.

  • Vitamin B12

Vitamin B12 is essential for healthy red blood cells, nerve cell development, brain function, and DNA production. (This is why it’s especially important for pregnant and nursing women.) Vitamin B12 can also impact your oral health. A B12 deficiency can cause a swollen, sore, or inflamed tongue, loss of taste, and gum, tongue, and mouth ulcers.

Unfortunately, vitamin B12 is reliably found only in animal foods and nutritional yeasts. If you would prefer an egg-free and dairy-free diet, look to B12 supplements or B12-fortified cereals, plant-based milks, energy bars, and other vegan options. This is a good subject to discuss with your physician, because even supplements and fortified foods might not provide enough B12.

In fact, Drs. Mark and James Kaley can be vital resources when you’re planning your healthiest vegetarian diet. The next time you visit our Greensboro, NC office, ask for recommendations for supplements if you’re concerned that diet alone can’t provide for all of your nutrition essentials. Finally, care should be taken to ensure that, even with supplements, you get the proper amount of the vitamins and minerals you need.

As a vegetarian, you are used to the concept of care. Whether it was concern for nutrition, the planet, the animal world, or another reason that drew you to a vegetarian diet, be sure to care for your body as well as your dietary choices. Careful planning can ensure a diet which supports not only your general health, but your oral health, for a lifetime of nourishing—and well-nourished—smiles.

Your Child’s First Visit to the Orthodontist

September 11th, 2025

We often think of braces as a rite of passage for kids in middle and high school. So you might be surprised when your child’s dentist recommends a visit to see Drs. Mark and James Kaley years earlier than you anticipated. In fact, dentists and orthodontists generally suggest a visit to the orthodontist by age seven at the latest.

Why see an orthodontist so early?

After all, your child is still growing, and many adult teeth haven’t come in at that age. And that’s the whole point.

Around this age, your child will probably have a mix of both baby and adult teeth, so your orthodontist will be able to assess whether there’s enough room for the permanent teeth to erupt without crowding or spacing problems. And malocclusions, or bad bites, caused by problems with jaw size or symmetry can be addressed while young bones are still forming and developing.

If your child has a first appointment coming up on the calendar, here’s a heads up on what often happens during a first visit, and potential problems your orthodontist will be on the lookout for.

What can you expect at a first visit?

The first visit is designed to evaluate how your child’s teeth and jaws work together now, and to look for potential future problems with tooth alignment and jaw structure and development.

First, Drs. Mark and James Kaley will carefully examine your child’s teeth, jaws, and mouth. Your child will be asked to bite down several times to see how the teeth and jaws fit together, and if there’s any discomfort. Other helpful diagnostic tools could include:

  • Scans or X-rays to evaluate jaw structure and the position of teeth which haven’t erupted yet
  • Photos of your child’s teeth and face
  • An impression of your child’s teeth

If there’s no immediate need for treatment, we might recommend periodic checkups at our Greensboro, NC orthodontic office to follow the growth and development of your child’s teeth and jaws. If interceptive (early) treatment is your child’s best option for a healthy smile, your orthodontist will explain any immediate orthodontic issues and design a treatment plan tailored to your child’s specific needs.

What are the benefits of early treatment?

Interceptive treatment not only helps correct current orthodontic problems, it can help reduce the need for more complicated treatment in the future, when all of the adult teeth have arrived and bones are fully formed. Among its many benefits, early treatment can:

  • Prevent crowding

If your child has a small upper palate, it can be gently enlarged while the palate is still growing with the help of a palatal expander. This will give the upper teeth the space they need to come in without crowding.

  • Provide space

If primary teeth are lost too early, other teeth can shift out of alignment to fill the empty space. A space maintainer can be custom-made to keep the spot open until the right tooth is ready to erupt. If primary teeth are overstaying their welcome, Drs. Mark and James Kaley might recommend extraction to allow the adult teeth to erupt in the proper place.

  • Create jaw symmetry

Malocclusions can develop because the upper or lower jaw is too narrow, too far forward, too far back, or the jawbones don’t fit together properly. Drs. Mark and James Kaley might suggest the use of a functional appliance such as the Herbst® appliance or headgear to help guide symmetrical bone development while your child’s young bones are still growing and forming.

  • Protect teeth

Children with overjets, or protruding upper teeth, are more likely to suffer chips, cracks, and other trauma to those vulnerable front teeth. Functional appliances can help bring the upper and lower jaws into alignment as needed, and braces can move the teeth into alignment.

Every journey to a healthy smile begins with a first visit. And you don’t need to wait until your child is seven. Any time you’re concerned about an orthodontic issue is a good time for a consultation. Talk to Drs. Mark and James Kaley about what to expect at your first visit to help create a comfortable experience for your child as you begin this journey together.               

Summer Smiles

September 4th, 2025

The “Back to School” ads are out already? Halloween candy’s showing up in stores? Just a minute—summer isn’t quite over yet! While the days are still sunny and warm, let’s look at a few cool ways to keep your smile bright with some healthy dental options:

  • Healthy Drinks

Hot summer days mean it’s time to hydrate. But sodas, fruit drinks, and sports drinks can have a lot of added sugars, which can mean added cavities. They can also be quite acidic, and acids break down tooth enamel. So, what to reach for on a hot day? Water!

Water is a good choice whenever you’re thirsty. Water is essential for healthy bodies and for healthy teeth and gums, too. Water helps wash away food particles which feed the cavity-causing bacteria in plaque. Acids in our foods and drinks break down tooth enamel, and water helps balance out those acids. If you have fluoridated water, fluoride makes enamel stronger and even helps reverse early decay.

  • Healthy Gear

It’s great to get outdoors again for sports like biking, water skiing, baseball, or hoops. And it’s great to keep your teeth safe while you’re active. A mouthguard will help protect your teeth and mouth from contact when you’re playing contact sports. If you wear braces, Drs. Mark and James Kaley can craft a mouthguard that will protect both your mouth and your braces!

If you’re just out of braces or aligners, don’t forget to wear your retainer. Retainers keep your teeth from moving out of position while your jawbones rebuild strong bone tissue around them. Make sure that healthy smile you worked so hard for stays looking its best.

Your appliances protect you, so return the favor and make sure your appliances stay healthy by cleaning them after use and storing them in their protective cases.

And remember to replace another piece of protective equipment regularly—your toothbrush. If you haven’t replaced your toothbrush for several months, it’s time to go shopping. Toothbrushes wear down over time, especially if you wear braces, and, after three months or so, can’t clean plaque as effectively. Which reminds us . . .

  • Healthy Habits

Even as we take advantage of the end of summer with last minute camping, or travel, or action-filled weekends, one thing should stay on schedule—regular brushing and flossing.

You should be brushing twice a day, for two minutes each time. If it’s hard to time yourself, try playing a favorite two-minute song or using a timer or even a brushing app. And don’t forget to floss! Floss gets into spaces where bushes can’t to remove plaque. Floss once a day to keep your teeth their cleanest. Be proactive if your orthodontist suggests more frequent brushing and flossing while you’re wearing braces.

Finally, don’t neglect your orthodontic care. Keep up with appointments at our Greensboro, NC office. If you wear aligners, wear them all the hours recommended. If you have bands, replace them daily and whenever they start to feel loose. If you have an appliance, use it as directed. The more you keep to your orthodontic schedule, the faster you’ll be enjoying your healthy, beautifully aligned smile.

Summer’s almost over, but these healthy tips work in fall, winter, and spring, too—for a smile that’s sunny and bright all year long!
