Dr. Kathleen Chan and Dr. Ivy Chen and our team strive to serve our patients by educating them about their treatments, as well as making them feel as comfortable as possible during their initial consultations up until the day they complete their treatments.

Making our patients more comfortable with taking care of their braces in between visits increases the likelihood that they will complete their treatments successfully. We want you to know that if you should ever have any questions about your orthodontic treatment, whether it’s during your adjustment appointment or after hours, we are always here for you and your family.

Please do not hesitate to give us a call at our Andover office or ask us any questions you may have on our Facebook page! We can’t wait to hear from you!

Brackets and wires, clear aligners, lingual braces, regular brackets, self-ligating braces, elastics, spacers—you and your orthodontist have had to narrow down a lot of choices to discover the best treatment for your orthodontic needs. Now that the end of treatment is in sight, there’s one more important choice left—your retainer!

Do I Need a Retainer?

No retainer at all is probably the one option that’s off the table from the start. It’s not just your teeth that have changed position; it’s the bone and ligaments holding them that have changed as well.

A retainer prevents your teeth from moving away from their new, ideal location while your bones and ligaments are stabilizing. This process takes months, so keeping your teeth in place as your bone rebuilds and regains density is crucial.

What Are Your Retainer Options?

Three of the most popular retainer options available at our Andover office include:

• Hawley Retainers

This is the traditional retainer, with wires to hold your retainer in place and to keep the teeth properly aligned. The wires are attached to an acrylic plate molded to fit the roof of your mouth or around your bottom teeth. You can customize the acrylic base with colors and patterns for a one-of-a-kind look.

Hawley retainers are adjustable, so minor realignments can take place if necessary. The wire in front of your teeth makes these retainers visible, but, after several months of wearing them all day long, you may end up wearing them only at night.

Hawley retainers are removable, so you need to make sure they are safely in a case when you’re not wearing them. Minor damage can often be repaired, but it’s better to be proactive.

• Clear Plastic Retainers

These retainers look like clear aligners. They are formed by heating a thin piece of plastic and vacuum-forming it around a model of your teeth to create a custom, comfortable fit.

Clear retainers are almost invisible when worn, and can be removed when you eat or drink—which they should be, because food particles and liquids can be trapped inside them.

When you’re not wearing it, a clear retainer should always be in its case, because it must be replaced if the plastic is warped, cracked, or broken.

• Fixed Retainers

A fixed retainer is a small single wire bonded to the back of specific teeth, commonly the six bottom front teeth. Because fixed retainers don’t allow the teeth to move at all, they are often recommended for patients who had serious misalignments, extremely crowded teeth, or teeth with large gaps between them.

Many patients like fixed retainers because they keep teeth in perfect alignment, they won’t be seen, they’re comfortably small, and they can’t end up in the cafeteria recycling bin because you forget to replace them after lunch!

Fixed retainers are usually quite durable, but you’ll need to pay attention to your diet, because crunchy and chewy foods can put pressure on the retainer and damage it. These retainers also require special care with brushing and flossing, to make sure the teeth bonded to the wire stay clean and plaque-free.

The Right Retainer

The process of stabilizing your teeth in the jaw takes time. Choosing your retainer will depend in part on how long and how often you need to wear it: fulltime for months or for years, at night after several months of day-and-night wear, or long-term to make sure your orthodontic work lasts.

And there are other variables, as well. Your retainer might need to be removable. It might need to be adjustable. You might need a retainer for just your upper teeth, just your lower teeth, or both. All these factors and more need to be taken into consideration before deciding on your ideal retainer.

Fixed, removable, wire, plastic, colorful, clear—which retainer is right for you? The one that helps you retain the beautiful smile you’ve worked for all these months. Talk to Dr. Kathleen Chan and Dr. Ivy Chen to discover the retainer that will protect that smile for years to come.

An overbite is one of the most common malocclusions. If Dr. Kathleen Chan and Dr. Ivy Chen 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. Kathleen Chan and Dr. Ivy Chen 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. Kathleen Chan and Dr. Ivy Chen 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 Andover 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. Kathleen Chan and Dr. Ivy Chen can provide the specific information and treatment plan you need to make that healthy bite and that confident smile a reality!  

Sometimes real life is stranger and more interesting that any made-up story. These weird and interesting facts about braces will amuse you … and make you glad you didn’t have to get braces “way back when.”

Mummies with braces: Archaeologists have discovered mummies with crude bands of metal wrapped around their teeth. The metal was wrapped around each individual tooth, and it is believed that ancient dentists used catgut to guide the teeth and close the gaps.

First “official” braces: The first official braces were constructed in 1728 by Pierre Fauchard. They consisted of flat strips of metal. String was used to connect the metal to the teeth.

Early rubber bands: In 1850, Tucker began making rubber bands out of rubber tubing.

Brackets are better: Brackets were invented by Edward Angle in 1915. They were not bonded to the teeth directly, but instead were attached to bands that went around the teeth.

Wiring by NASA: As braces have become more modern, the technology has improved by leaps and bounds. You may know that some braces wire contains nickel titanium. What you may not know is that this metal was developed by NASA and has special shape memory that is activated by pressure or body heat.

Over 60 with braces: Actress Faye Dunaway got braces at the age of 61, which shows you are never too old to look more fabulous!

Oh, and one more thing that didn’t quite make our list, but is interesting all the same. Did you know that almost 25 percent of patients who get braces have to get them again because they wouldn’t wear their retainers? So suck it up, buttercup, and use that retainer!
