We all had a wonderful time celebrating our new year with our families and friends. Our goals this year are to focus on our self-care and try as many new foods as we can! What are your goals?   

This month we are excited to celebrate Nicole who has been with us for 10 years and Victoria who has been with us for 13 years! Make sure to congratulate them on their work anniversaries. 

This year we are focusing our time on continuing to provide outstanding and personalized orthodontic care to all our patients. Caring for you and your family and positively transforming smiles is something that we care about very much. 

If you are looking for orthodontic treatment this year, you can call us to schedule your complimentary initial consultation. We will work closely with both you and your dental professionals to provide you with a comprehensive care plan. 

Whether you are a new or returning patient, we can’t wait to help you achieve the smile of your dreams!  

You’ve worked hard for your attractive, healthy smile, and now you’re making sure it stays attractive and healthy by wearing your retainer. Since wearing a retainer is usually a matter of years, not months, it’s natural to wonder just how long you can count on that retainer to help you maintain your smile.

That answer depends on the type of retainer you get at our Andover office. A Hawley retainer, a clear retainer, and a fixed wire retainer have different lifespans. Because they each have their own advantages, Dr. Kathleen Chan and Dr. Ivy Chen will recommend the retainer that’s right for protecting your individual smile.

So let’s look at the average lifespan for different retainers, and, equally important, some of the common mishaps that can shorten that working life.

The Hawley Retainer

This is the retainer most people picture when they think “retainer.” Made of wire securely attached to an acrylic base, the Hawley retainer keeps the teeth in place, and can even be adjusted, if needed, to improve alignment. They generally last anywhere from three to ten years.

How can you make sure your Hawley retainer keeps working for you as long as possible?

• Keep it in its case. While some damages to these retainers can be repaired, why take a chance? And it’s much harder to lose a retainer if it’s in its case as opposed to, say, a cafeteria napkin.
• Keep it away from your pet. Dogs, especially, are tempted by the taste and smell of saliva, but there are safer, less expensive chew toys out there.
• Keep wearing it. Without your retainer, your teeth can shift. Over time, not only will your retainer fail to fit anymore, but you might need to return for further orthodontic treatment. If you notice your retainer is starting to feel uncomfortable, give your orthodontist a call.

The Clear Retainer

Clear retainers look like clear aligners, and, like clear aligners, are almost invisible. Made of vacuum-formed plastic, they’re designed for a close, comfortable fit, often around the entire arch of your teeth. Also like clear aligners, these retainers aren’t made to last forever. If they become loose, warped, or cracked, they should be replaced. With care, they can last from six months to several years. How to protect them?

• Protect your retainer from damage. Keep it in its case when you’re not wearing it. You’ll avoid losing it, and you’ll avoid damaging it.
• Protect it from teeth. And we don’t just mean pets, although they find clear retainers yummy, too. If you grind your teeth, your retainer can suffer. Clear retainers are not the same thing as night guards, so talk to your orthodontist for recommendations.
• Protect it from heat. Hot surfaces like ovens or heaters, hot dashboards, washers and dryers, even very hot drinks can be a problem. (You should only be drinking water while you wear your clear retainer, so that particular issue shouldn’t arise!)

The Fixed Retainer

A fixed retainer is a small piece of wire that is custom-fit and bonded to the back of specific teeth to prevent any movement from occurring. Because it’s bonded to the inside of the teeth, a fixed retainer is completely invisible when you speak or smile. It can last five years, ten years, and in some cases, even longer. Even though you won’t be exposing this retainer to external dangers like hungry pups or the wash-and-rinse cycle, there are still some situations to watch for:

• Watch your diet. The same sticky, crunchy, or hard foods that can damage brackets and wires can also loosen a fixed retainer.
• Watch your dental hygiene. While cleaning around a bonded retainer can be a bit challenging, not cleaning around it can result in plaque and tartar buildup—and your retainer might have to be removed to clean your teeth.
• Watch for changes. If your teeth start to shift, it could mean your retainer has detached from one or more teeth. Ask your dentist to check the retainer’s bond whenever you have a checkup.

So, how long will that retainer last? Depending on the kind of retainer you have, if you don’t keep it in its case, or if you don’t watch your diet, or if you expose it to heat, the answer is—not nearly long enough. Dr. Kathleen Chan and Dr. Ivy Chen will give you the very best tips to keep your retainer clean, safe, and working for as long as possible. Now, it’s up to you!

Some foods are just terrible for your teeth — think cookies and candy bars — but there are certain foods that are beneficial to your oral health. Below, Dr. Kathleen Chan and Dr. Ivy Chen and our team have covered five of the top foods to keep your teeth and gums healthy!

1. Crispy, low-acid fruits and vegetables: Fruits like apples and vegetables such as carrots and celery act like “natural toothbrushes,” helping to clear plaque from your teeth and freshen your breath.

2. Kiwis: These little green superstars are packed with vitamin C which is essential for gum health. The collagen in your gums is strengthened when you consume foods that are high in vitamin C, like kiwis, thus helping to prevent periodontal problems.

3. Raw onions: Onions have long been studied for their antimicrobial, antibacterial, and antioxidant properties. Proliferation of bacteria is what leads to tooth decay and cavities. By including raw onions in your diet, you'll be doing your part to wipe out those little microbes before they can multiply!

4. Shiitake Mushrooms: A specific compound in shiitake mushrooms, lentinan, has been shown to have antibacterial properties that target the microbes that cause cavities while leaving other beneficial bacteria alone. It may also help prevent gingivitis, or inflammation of the gums.

5. Green Tea: Often lauded for its high antioxidant content and many health benefits, it turns out green tea also benefits your oral health! A Japanese study found men who drank green tea on a regular basis had a lower occurrence of periodontal disease compared to men who drank green tea infrequently. It's believed this is due to the catechins in green tea, a type of flavonoid that may help protect you from free radical damage, but more research needs to be done. Either way, drink up for your overall health, as well as your teeth!

Some experiences are great, and we look forward to enjoying them again and again. Others have wonderful outcomes, but you feel no need for a sequel. If you’re wondering whether you need to revisit orthodontic treatment, you’re probably in this second group.

After all, you put in your time as a teenager. All those days in bands and braces, all the adjustments, all that cleaning with little tiny tools in little tiny places. That was a lot of work, and you reaped the rewards of your conscientious orthodontic habits with beautifully aligned teeth and a healthy, comfortable bite.

But now you’ve started to notice that your teeth aren’t quite as beautifully aligned, or your bite’s not quite as comfortable. So, what’s happened? Let’s look at some possibilities, and whether a return to the orthodontist’s office is in order.

• You’ve Lost a Tooth

If you’ve lost a tooth because of injury or decay, that gap is an open invitation for surrounding teeth to move in to fill the void. Whenever you lose a tooth, consider an implant. Implants function, look, and maintain healthy spacing just like natural teeth.

One thing implants can’t do? Move like our own teeth will during orthodontic treatment. Your natural teeth can move because they are held in place within the bone by flexible periodontal ligaments. Implants, on the other hand, are anchored directly to the bone for stability.

If you’re considering new or further orthodontic work and want to replace a lost tooth with an implant, it’s a good idea to talk to Dr. Kathleen Chan and Dr. Ivy Chen to discover the best timing and scheduling for your procedures.

• You’ve Gained a Tooth

Problems with your alignment can also arise if you add a tooth or teeth. If you’re in your late teens or early twenties, wisdom teeth could be in your near future. And a new tooth can throw off the spacing and alignment of your existing teeth.

Talk to Dr. Kathleen Chan and Dr. Ivy Chen about your options if your wisdom teeth are about to make an appearance, and if it looks like your tooth and bite alignment might be affected.

• You’re Getting Older

Our teeth naturally tend to shift as we age. Teeth move forward, causing crowded or crooked front teeth—especially on the lower jaw. There’s even a medical term for this phenomenon: mesial drift. While we don’t know exactly why this drifting occurs, we can treat it.

Adults make up a large—and growing—segment of orthodontic patients. If your teeth have lost their ideal alignment over time, a visit to our Andover office is a great way to bring your youthful smile back. And you’ll probably find your treatment much shorter and more comfortable than it was decades earlier!

• You Haven’t Been Wearing Your Retainer

Remember that word “conscientious” in the second paragraph? You need to wear your retainer conscientiously, for as often and for as long as recommended by Dr. Kathleen Chan and Dr. Ivy Chen.

If you’ve been ignoring a damaged retainer, or you keep forgetting to look for your lost retainer, or you have a perfect, undamaged retainer sitting unworn on your dresser, your teeth can start to shift out of their hard-won alignment within a short time.

Does this mean it’s back to months of bands and adjustments and appointments? Maybe not! See us as soon as you notice any changes in your teeth or bite. When caught early, shifting teeth can be treated much more easily.

What can we do to help you regain your best smile? A lot!

• Treatment Planning

When you need to accommodate implants, wisdom teeth, or other dental work which could affect your tooth alignment, Dr. Kathleen Chan and Dr. Ivy Chen can work with your dentist to make sure your alignment isn’t disturbed in the process. They can also map out a treatment schedule which coordinates your other procedures with any orthodontic treatment.

• Retainer Evaluation/Adjustment

Your retainer is probably a passive retainer, meaning it keeps your teeth in place instead of moving them. If you notice your alignment shifting, or if your retainer is uncomfortable when you try to put it on after a lapse in nightly wear, ask us about a replacement.

• Active Retainers

An active retainer helps move teeth into alignment rather than simply keeping them in place. A new active retainer might be just what you need to correct a slight shift.

• Aligners or Braces

If you have some serious shifting going on, we might recommend a second round of treatment with clear aligners or braces. But there’s good news here, as well! Treatment to correct an orthodontic relapse usually takes less time than it did originally, and treatment options are more comfortable and less noticeable than ever before.

Talk to Dr. Kathleen Chan and Dr. Ivy Chen about an orthodontic sequel if you have any concerns about changes in your bite or alignment. You might need only a simple retainer adjustment or a short time in clear aligners or traditional braces to make your smile its best and healthiest once again. And this time, remember to wear your retainer to make sure there’s no need for Orthodontics—Part III!
