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. Kathleen Chan and Dr. Ivy Chen 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. Kathleen Chan and Dr. Ivy Chen 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. Kathleen Chan and Dr. Ivy Chen 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 Andover team about which retainer option will be best for making sure that this smile lasts a lifetime.

Dr. Kathleen Chan and Dr. Ivy Chen and our team hear this question a lot. Some of the common reasons for crooked teeth include:

• Thumb sucking
• Tongue thrusting or improper use of the tongue during speaking and swallowing
• Premature loss of baby teeth, which causes teeth to drift and shift
• Poor breathing airway caused by enlarged adenoids or tonsils

There are also hereditary factors we get from our parents, like:

• Extra teeth
• Large teeth
• Missing teeth
• Wide spaces between teeth
• Small jaws

Dr. Kathleen Chan and Dr. Ivy Chen and our team know that having crooked teeth isn’t just a cosmetic issue; it can lead to serious health problems as well. Crooked teeth can:

• Interfere with proper chewing
• Make keeping teeth clean more of a challenge, increasing the risk of tooth decay, cavities, and gingivitis
• Strain the teeth, jaws, and muscles, increasing the risk of breaking a tooth

There are several treatment options we offer at Chan & Chen Orthodontics that can help correct crooked teeth. Please give us a call at our convenient Andover office to learn more or to schedule an initial consultation.

According to Preferred Consumer, it's estimated that 50 percent of people around the world have teeth that are crooked, not aligned properly, or irregular. Fortunately today, orthodontics has advanced to the point where corrective devices, such as braces and retainers, are less obvious, more comfortable, and can be worn for shorter periods of time.

So, with that being said, how do you know if braces are right for you? Typically your dentist will be able to point out any issues with your teeth at your regular six-month cleanings and recommend you to an orthodontist. But here are some other things to keep in mind when deciding whether or not braces could be in your future:

Crooked Teeth

As children grow, so do their teeth. And more often than not, certain teeth will grow in crooked. This isn't uncommon, as the majority of children will require some sort of teeth correction, whether that’s braces or retainers. Retainers are custom-made devices that either work to hold teeth in place or correct tooth alignment. They're often worn all day, aside from meals, at the start of the treatment period and then eventually are rolled back so they're just worn at night. Braces on the other hand are worn for at least a year and work to help straighten or position teeth.

Overbite or Underbite

The other main oral issue that orthodontics helps correct is uneven alignment, such as an underbite or an overbite. You might hear Dr. Kathleen Chan and Dr. Ivy Chen refer to this as a "malocclusion," which means "bad bite." Braces can help rearrange your alignment so an overbite or underbite is less of a problem. Typically after the braces come off for this sort of treatment, patients need to wear a retainer from Chan & Chen Orthodontics to finish the treatment.

While braces are typically associated with dental issues in children, more adults are wearing the devices as well. About one in every five braces wearers are adults; a sign that it's never too late to correct any oral issues. Part of this is due to the technological advancements in orthodontics. For instance, new braces feel much better and come in a variety of styles — including clear — so they're far less obvious. Plus, the wires on braces are now made from advanced metals, which are stronger and lighter, so they get the job done much more efficiently. With so many people wearing braces these days, nicknames like "metal mouth" and "brace face" are almost a thing of the past. What's more, is that insurance plans are increasingly covering orthodontic treatment, making braces a much more feasible option for families on a budget.

When weighing whether or not braces are in your future, it's important to study all of your options about the styles of braces and what treatment option is best for you. Also be sure to contact your insurance provider to see what is covered and what will have to be paid out of pocket. It might take a few years of treatment, but braces can give you that winning smile for the rest of your life. Call our Andover office with any questions you might have!

When we think of Valentine’s Day, we think of cards, flowers, and chocolates. We think of girlfriends celebrating being single together and couples celebrating their relationship. We think of all things pink and red taking over every pharmacy and grocery store imaginable. But what Dr. Kathleen Chan and Dr. Ivy Chen and our team would like to think of is when and how this joyous, love-filled day began.

Several martyrs’ stories are associated with the origins of Valentine’s Day. One of the most widely known suggests that Valentine was a Roman priest who went against the law at a time when marriage had been banned for young men. He continued to perform marriage ceremonies for young lovers in secret and when he was discovered, he was sentenced to death.

Another tale claims that Valentine was killed for helping Christians escape from Roman prisons. Yet another says that Valentine himself sent the first valentine when he fell in love with a girl and sent her a letter and signed it, “From your Valentine.”

Other claims suggest that it all began when Geoffrey Chaucer, an Englishman often referred to as the father of English literature, wrote a poem that was the first to connect St. Valentine to romance. From there, it evolved into a day when lovers would express their feelings for each other. Cue the flowers, sweets, and cards!

Regardless of where the holiday came from, these stories all have one thing in common: They celebrate the love we are capable of as human beings. And though that’s largely in a romantic spirit these days, it doesn’t have to be. You could celebrate love for a sister, a friend, a parent, even a pet.

We hope all our patients know how much we love them! Wishing you all a very happy Valentine’s Day from the team at Chan & Chen Orthodontics!
