Overbite or Overjet?

October 17th, 2025

The words “overbite” and “overjet” certainly sound similar. Both conditions concern your front teeth. Both conditions fall under the same category of bite problems—Class II malocclusions, if you want to be technical. So it’s not surprising that they’re often used interchangeably. But while there are similarities, overbite and overjet are also distinctly different.

  • Overbite/Overjet Geometry

In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.” With a Class II malocclusion, the upper front teeth project further beyond the lower teeth than they should.

Of course, teeth and bites are as individual as we are, so there are variations in just how and just how much the overlap occurs. In diagnosing an overbite vs. an overjet, the difference comes down to a matter of vertical vs. horizontal.

An overbite, or deep bite, occurs when the top teeth vertically overlap the bottom teeth more than they should for a healthy bite. Generally, when a person’s top teeth cover more than a quarter of the bottom teeth when biting down, or more than two to three millimeters, that person is said to have an overbite.

An overjet, commonly known as protruding or buck teeth, is the result of a horizontal overlap that is broader than normal. This causes the top teeth to project outward toward the lips more than they do in a typical bite. An overjet is usually diagnosed when the horizontal distance between the top and bottom teeth exceeds two to three millimeters.

  • Overbite/Overjet Causes

The causes for both an overbite and an overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both. These bite problems can run in families. They are also affected by the size and position of the jaws and the shape and position of the teeth.

Early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to the development of a Class II malocclusion, particularly an overjet. Consistent pressure from thump or pacifier pushes the teeth outward as they erupt, which encourages them to protrude. These oral habits can affect the shape of the palate and jaw, too.

  • Overbite/Overjet Treatments

There are many types of treatment available to correct teeth and bite misalignments. Drs. Mark and James Kaley will tailor your treatment to your specific malocclusion for the best orthodontic outcome.

If you have a mild malocclusion, and minor dental issues are the main cause of that malocclusion, either braces or clear aligners can be effective for an overjet or an overbite. Elastics (rubber bands) are often used as part of this treatment.

If the malocclusion is due to bite problems caused by uneven upper and lower jaw development, devices called functional appliances can be used with braces to help guide the growth of the jawbones while young patients’ bones are still forming. These include appliances that work inside the mouth to help the upper and lower jaws grow proportionally, and external appliances such as headgear.

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself. Orthodontic treatment is usually needed as well both before and after surgery.

  • Overbite/Overjet Consequences

Over time, a deep overbite can cause damaged gum tissue, worn enamel, and fractured teeth. When teeth protrude because of an overjet, they can lead to self-consciousness and are more at risk for injury. Both malocclusions share dental and medical consequences, including concerns about facial and jaw appearance, problems speaking or chewing, headaches, and face and jaw pain.

Class II malocclusions aren’t all the same, and orthodontic patients aren’t all the same either. You may have a minor malocclusion or a significant one. You may have an overbite, or an overjet, or a combination of different bite and alignment concerns. Your malocclusion may not bother you at all, or it may cause pain, discomfort, or self-consciousness.

That’s why every overbite or overjet should be evaluated by an orthodontist. When you visit our Greensboro, NC orthodontic office, Drs. Mark and James Kaley will be able to diagnose the exact nature of your malocclusion, the reason for it, and your best individualized treatment plan. An overbite and an overjet are different malocclusions, but you and your orthodontist want the same outcome for each: a healthy, attractive, and confident smile!

October is National Orthodontic Health Month

October 16th, 2025

What does the month of October mean to you? For people in the northern hemisphere, October is when the weather starts to get a little chilly: heavy jackets might come out of storage and the summer clothing gets packed away. You might start making plans for the upcoming holidays or looking at the beautiful and changing autumn scenery. October means something a little different to our team at Kaley Orthodontics because this is National Orthodontic Health Month. During October, orthodontic clinics all over the country work together to promote their services and inform the community about the important work we do.

National Orthodontic Health Month is an awareness campaign created cooperatively by orthodontists and other dental health professionals. During this month, we make a special effort to promote dental health and orthodontic health in particular. This is a great time to get your questions answered by dental professionals in your community and to learn more about exactly what an orthodontist can do for you and your family. Events held in connection with National Orthodontic Health Month are also an opportunity for us orthodontists to come out and meet community members. If you have never been to an orthodontist before, you might not know what to expect. Meeting one of us in person before your checkup is a great way to find out what kind of person you’ll be seeing during your appointment.

Meeting Drs. Mark and James Kaley in a relaxed “meet and greet” atmosphere can be especially helpful for any young orthodontic patients in your family. Kids of all ages–and their parents!–can feel anxiety about going to the dentist. Getting to know the person you have an appointment with can make the experience a lot less stressful for everyone. We don't want anyone to avoid seeing a dental professional for regular checkups just because they don't know who we are. Just meeting and talking with the orthodontist you'll be seeing may be enough to make you feel more comfortable about your upcoming appointment.

Dental health is something that affects everyone; healthy teeth and gums contribute to a healthy smile and a lifetime of comfort and well-being. Orthodontists are just one of the various dental practitioners you could visit at some point in your life, so taking a little time to learn who we are and what we do is certain to be a helpful experience. We look forward to seeing you and your family this October at our Greensboro, NC location!

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.
