An overbite is one of the most common malocclusions. If Dr. Cronin and our team have diagnosed you with an overbite, you probably have lots of questions. Let’s try to answer some of them!

Just what is an “overbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. A normal overlap is generally considered one or two millimeters.

An overbite is a Class II malocclusion, and means that the upper front teeth cover more of the lower teeth than they should. But that’s a very general definition, and we will diagnose and treat your own, very specific, bite and teeth alignment.

Because overbites aren’t all alike. They might be barely noticeable. Upper teeth might overlap lowers by an extra millimeter or two. In more severe overbites, the upper teeth might cover the lower teeth completely. The amount of overlap and the cause of the overbite will determine your treatment.

What causes an overbite?

Overbites can be dental, caused by tooth alignment, or skeletal, caused by bone development, or a combination of both. They are usually hereditary, so, most often, an overbite is something you’re born with.

The size and position of your jaws, the shape and position of your teeth, all affect your bite alignment. But early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use can contribute to overbite development. Missing teeth and bruxism, or tooth grinding, can also affect the alignment of your bite.

How do we treat an overbite?

There are many types of treatment available. Dr. Cronin will recommend a treatment plan based on the type and severity of your overbite. Because some treatments are effective while bones are still growing, your age plays a part as well.

• Braces and Aligners

If dental issues are the main reason for your overbite, braces or clear aligners can be very effective. Rubber bands are commonly used to help bring teeth and jaw into alignment.

• Functional Appliances

If the overbite is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still forming.

For young patients, there are several appliances that can help correct an overbite. Some, like the Herbst appliance, work inside the mouth, while others, like headgear, are worn externally. Your orthodontist will recommend the most effective appliance for your needs.

• Surgical treatment

In some cases, where the problem is skeletal rather than dental, surgical treatment might be necessary to reshape the jawbone itself. This is especially true for adults, whose bones have finished forming.

If we recommend surgery, oral and maxillofacial surgeons are experts in surgical procedures designed to create a healthy and symmetrical jaw alignment. Dr. Cronin will work with your surgeon to design a treatment plan, which will usually include braces or other appliances following surgery.

Why treat your overbite?

Sometimes, a very slight overbite won’t require treatment. A serious, moderate, or even mild overbite, though, can lead to many dental and medical problems, including:

• Crooked, crowded teeth
• Worn teeth and enamel
• Problems speaking or chewing
• Difficulty sleeping
• Headaches, facial, and temporomandibular (jaw) joint pain

When you work with our Langley team to correct your overbite, you’ll not only prevent these unpleasant consequences, but you’ll achieve major benefits as well—a healthy, comfortable bite, and an attractive, confident smile. If you’d like more than an overbite overview, Dr. Cronin can provide the specific information and treatment plan you need to make that healthy bite and that confident smile a reality!  

Congratulations! You’ve done the hard work necessary to create your beautiful smile! You’ve carefully completed all the steps needed to reach the end of your orthodontic journey. Well, nearly all the steps. We can’t forget that last step which will ensure that all your hard work is rewarded.

When you first began orthodontic treatment, Dr. Cronin decided on the best plan for straightening your teeth and perfecting your bite, whether you wore traditional braces, lingual braces, aligners, or other orthodontic appliances. And now that you’re finishing treatment, there’s one more option to consider—your retainer.

Why do I need a retainer?

While you’ve spent time in treatment, more has changed than just the position of your teeth. The periodontal ligament, the connective tissue that connects the teeth to the jawbone, is stretched as the teeth shift. The bone in your jaw changes, too, reforming and rebuilding around the roots of your teeth as they move to their ideal locations.

These changes happen because your braces or aligners apply gentle, constant pressure to move your teeth. When you’ve finished wearing these appliances, the pressure stops. Ligaments will try to return to their original shape, which can shift teeth back toward their old positions. And the rebuilding bone isn’t dense enough yet to stop teeth from shifting due to the normal, everyday pressures of eating, chewing, and smiling.

A retainer prevents your teeth from moving back, or “relapsing,” by giving your bones and ligaments time to stabilize and rebuild. The process takes months, so keeping your teeth in place as bones rebuild and grow denser is crucial. This is especially important for patients with more serious misalignments. Dr. Cronin will let you know which kind of retainer will be best for you and just how long you’ll need to wear your retainer.

Are there different kinds of retainers?

There are! Retainers can be removable or fixed, visible or nearly invisible, metal, plastic, or metal and plastic. Three of the most popular retainer options include:

• Hawley Retainers—the traditional removable retainer, which uses a molded acrylic plate with wires attached to keep your teeth properly aligned and to hold your retainer in place.
• Clear Plastic Retainers—a removable retainer made of custom vacuum-formed plastic, which fits over the teeth like a clear aligner.
• Fixed Retainers—a small single wire bonded to the back of specific teeth, which holds them in place and prevents any movement.

Dr. Cronin will let you know whether a removable or fixed retainer is best for making sure your teeth don’t start to relapse, and fill you in on the benefits and care of each type of retainer.

How long do I need to wear a retainer?

There’s no standard answer to this question. Just like your retainer is custom-built to fit your individual teeth, the amount of time you’ll spend in that retainer depends on your individual needs. Retainers might be worn fulltime for months or years, be worn only at night after several months of daily wear, or be worn long-term to make sure your orthodontic work lasts.

Because you’ve done the hard work already, and your beautiful, healthy smile is the result. Talk to a member of our Langley team about which retainer option will be best for making sure that this smile lasts a lifetime.

If you play a contact sport, you know about mouthguards. You know about the cushioning protection they provide for your teeth. And not just your teeth—mouthguards also help protect your lips, tongue, and jaw, helping you avoid or minimize many of the injuries caused by collisions.

But you don’t have to be part of the defensive line or face off on center ice to wear a mouthguard. It pays to be proactive with your oral health in any activity where impact is a possibility. Whether you play a team sport, practice gymnastics, ride a bike, ski, skateboard, or participate in other athletic pastimes, there’s almost always the risk of impact—with a ball, with the mat, with the sidewalk, with another person.

So, how do mouthguards protect your teeth and mouth? It’s a combination of materials and design. Mouthguards are made of a strong, cushioning material such as plastic or silicone which helps absorb and distribute the force of impact, usually in the form of a horseshoe-shaped piece which fits over your upper teeth. The specific design can be tailored to the sport or activity you’ll be using it for.

And now that you’re wearing braces? Working toward an attractive, healthy smile doesn’t mean you can’t be active or find a mouthguard which will work for you. In fact, when you wear braces, mouthguards do double duty—they protect your mouth and teeth, and they protect your braces, too!

Even minor impacts can damage wires and brackets, and damaged braces means more time at the orthodontist and lost treatment time. More important, your guard not only helps protect your brackets and wires from impact injury, it protects your delicate mouth tissue from trauma caused by impact with your brackets and wires.

Because you probably have braces on both upper and lower teeth, the usual mouthguard design might not work for you. To make sure you’re completely protected, you may need a guard which covers both upper and lower arches.

There are over-the-counter mouth guards designed for braces, and even for covering both your upper and lower teeth. These might be one-size-fits-all or fit-it-yourself guards, or models which should be used only after a fitting at our Langley orthodontic office. While some of these guards are better than others, the best option for your teeth—and your braces—might be a custom mouthguard.

What are the benefits of a custom guard for orthodontic patients? They:

• Provide a perfect fit around teeth and braces
• Protect better because they fit better
• Are designed for easy breathing and speaking
• Are less bulky
• Are more durable
• Fit more comfortably
• Can accommodate orthodontic adjustments
• Can be tailored to your specific sport or activity.

Custom mouthguards are more expensive, because they are individually crafted for your teeth and braces, but in terms of effectiveness, they are the best guards out there—because they are individually crafted for your teeth and braces. If cost is an issue, Dr. Cronin can let you know whether an over-the-counter option might work for you.

An active life should mean proactive dental care. Wearing a mouthguard when you’re wearing braces protects both your body and your orthodontics. Whichever guard option you choose, it’s a good idea to check out the fit with Dr. Cronin to make sure you’re getting all the protection you need for both when your mouthguard is doing double duty.

There are many great reasons to see an orthodontist. For a healthier bite. For straighter teeth. For a more confident smile. So why are you hesitating? If the visibility of traditional braces is what’s holding you back, ask Dr. Cronin about lingual braces.

With regular braces, brackets are bonded to the front of each tooth with a special adhesive. Ligatures around each bracket or bracket clips grip an archwire, which does the work of moving the teeth. The gentle pressure from the wire guides the teeth into alignment in gradual stages. Every adjustment moves the teeth to their perfect positions. These braces are quite effective—and they are usually quite visible.

Lingual braces, on the other hand, are virtually invisible. Lingual means “toward the tongue,” and this placement is the difference between lingual braces and more traditional types of orthodontic braces.

Lingual braces are custom designed to be applied to the inside of your teeth. Specially designed brackets are attached to the backs of the teeth. Individually crafted archwires are used to guide your teeth to their best alignment.

Lingual braces can be the solution to many orthodontic concerns:

• If you need or want invisible braces for personal or professional reasons, lingual braces are a great option. Because they are behind your teeth, they are even less noticeable than clear aligners—and you don’t need to keep track of your hours wearing them.
• Lingual braces keep the front of your teeth braces-free for playing a brass or reed instrument, or for participating in sports. (Just remember, a mouthguard is always a good idea for athletic activities, and especially when you wear braces.)
• Both brackets and wires can be customized to fit your teeth perfectly, and new lingual brackets and wires are more comfortable than ever.

You might be a good candidate for lingual braces if:

• You have a large enough tooth surface to place a bracket. Adults with small teeth—or children—might not be have enough room on the back of each tooth to hold a bracket.
• You don’t have a major malocclusion (bite problem) which would make lingual braces impractical. A deep overbite, for example, could cause the wires and brackets behind the upper teeth to come loose or detach as they come in contact with lower teeth.
• You are dedicated to keeping up with your oral hygiene. Because wires and brackets are behind the teeth, it can be harder to keep them free from food particles and plaque.

Finally, even if lingual braces aren’t the perfect match for your orthodontic needs, there are other options that can work for you. Smaller metal brackets, ceramic brackets that blend in with your enamel, and clear aligners mean today’s orthodontic work is more subtle and discreet than ever before.
