As students gear up for the new school year, it's time to get their back-to-school appointments taken care of. If you haven’t yet, remember to schedule your child’s orthodontic adjustment. If you haven’t scheduled with us before, now is also a great time to book an orthodontic consultation to plan any necessary treatment for the upcoming school year.

Our practice offers flexible appointment times from 9:00 to 5:00. If you need to schedule an appointment that might conflict with school hours, we can provide an excused absence note. Just let us know before you leave if you need one.

If your student is wearing braces, remind them to take extra care of their teeth. If they plan on doing sports, wearing a mouthguard is crucial. Remember to also leave time after breakfast to brush teeth before heading out the door. And make sure to brush teeth after school to remove all the food your students ate during the day.

Speaking of food, there are certain foods that are better for your oral health. Avoid soda and energy drinks due to their high sugar and acid content, which can be particularly harmful when you have braces or aligners. On top of that, we recommend you brush your teeth at least three times a day. For those with braces, steer clear of hard, crunchy, sticky, and chewy foods. Avoid popcorn and gum and remember to cut your food into smaller pieces and chew slowly.

For students wearing retainers or aligners to school, always carry your case. Anytime your appliance is not in your mouth, make sure it is in your case. There are only two places they are allowed to be - in your mouth or in your case!

August 22 is National Tooth Fairy Day! If the Tooth Fairy is a treasured part of your child’s life, you’re just in time to celebrate! But what to do when the Tooth Fairy doesn’t arrive on schedule—when baby teeth stay longer than expected or are lost too soon? 

A baby’s 20 baby teeth tend to come in within a fairly predictable time frame. The bottom central incisors in the very front of your baby’s mouth typically make their appearance first, when your baby is around six to ten months old. Over the next few years, the remaining incisors, canines, and first molars arrive. Last on the scene are the second molars, which usually show up between the ages of 23-33 months. 

Just as baby teeth follow a pattern coming in, they tend to follow the same pattern falling out. The front teeth begin to wiggle and loosen around age six or seven, while the last of the baby teeth, the canines and second molars, are often lost between the ages of ten and 12. 

Baby teeth fall out as the adult teeth below them push up as they erupt. The top of the new tooth puts pressure on the root of the baby tooth, gradually dissolving it. As the root grows smaller and can’t anchor the tooth, the tooth begins to wiggle and eventually becomes loose enough to fall out. This leaves the adult tooth perfectly placed to grow into its proper position.

Sometimes, though, teeth linger far past their fall-out date. Sometimes, because of decay or trauma, they are lost much too early. In either case, Dr. Kathleen Chan and Dr. Ivy Chen can provide treatment to protect little smiles now and to ensure that there’s space for the permanent teeth to erupt and align correctly.

Teeth Which Overstay Their Welcome

If that baby tooth never gets wiggly, the team at Chan & Chen Orthodontics can help! When baby teeth stubbornly hang on, adult teeth can erupt behind them, creating a double row of teeth commonly known as “shark teeth.” These permanent teeth can become crowded or misaligned as they try to fit in any space available. Or a baby tooth can block an adult tooth from erupting at all. When that baby tooth just isn’t budging, an extraction will create space for the permanent tooth to erupt.

Extracting a baby tooth is generally a straightforward procedure because primary teeth have very small roots. Your child’s dental team at Chan & Chen Orthodontics are experts in helping you prepare your child for the procedure in a gentle, reassuring, and age-appropriate way. 

Often, a local anesthetic is all that’s necessary for a simple extraction, but if you feel sedation would better fit your child’s needs, discuss sedation options with your dentist. After the extraction, you’ll be given clear information on how to deal with pain and swelling, which foods and drinks are best while the extraction site heals, and how to protect the area.

Teeth Which Exit Too Early

In the case of decay or trauma, your child’s dentist will do everything possible to save the tooth. When decay is so extensive that there’s not enough structure left to hold a filling or crown, or when there’s an infection in or around the tooth, or when an accident or injury has caused serious damage, extraction might be the healthiest option. Depending on your child’s age, further treatment might be needed afterward to protect future smiles. 

Besides their roles in eating and speaking, baby teeth save space for permanent teeth. If remaining baby teeth shift, taking up part of the empty space left behind by the lost tooth, the adult teeth below won’t have the space they need to align properly as they arrive. Permanent teeth could come in at an awkward angle or erupt in the wrong spot. 

To prevent these problems, your dentist might recommend that your child visit an orthodontist for a space maintainer. Space maintainers are small, custom-designed appliances which keep the remaining baby teeth in place. This prevents neighboring teeth from shifting to fill the empty spot and ensures that there’s enough room for the adult tooth to arrive right on schedule and right where it belongs. 

It’s comforting to have charts which let us know when little teeth will typically come in and when they will typically fall out. But unexpected events might mean teeth overstay their welcome or depart too soon. When the Tooth Fairy can’t keep to her schedule, schedule an appointment at Chan & Chen Orthodontics in Andover as soon as possible to make sure your child is on track for a future of healthy smiles.

Did you know that there’s a World Orthodontic Health Day in May? Or that National Orthodontic Health Month takes place in October? You may not have circled these days on the calendar—in fact, this might be the first time you’ve heard about them! But celebrating these special days is just one way that orthodontists share the health benefits of orthodontic treatment with us.

That’s because orthodontic treatment is about more than creating a beautiful smile. With the help of Dr. Kathleen Chan and Dr. Ivy Chen, you might also be creating:

• Healthier Teeth and Gums

When your teeth are aligned, it’s easier to prevent tooth decay and gum disease. Crowded, crooked, or overlapping teeth make it harder to brush and floss as effectively. Plaque that builds up in those hard-to-reach places on the tooth enamel helps create cavities. And over time, built-up plaque turns into tartar, a leading cause of receding gums and gum disease. Straight, properly spaced teeth make efficient brushing and flossing a breeze!

• A Comfortable, Functional Bite

A malocclusion, or bad bite, occurs when the teeth and jaws don’t align properly. In a healthy bite, teeth aren’t crowded, twisted, or spaced too widely apart. The top teeth should slightly overlap the lower teeth. And the ridges of your upper molars should fit smoothly with the grooves of the lower molars.

If your bite is off, you’ve probably noticed chewing pain, headaches, or jaw pain. Over time, malocclusions can lead to worn enamel, cracked teeth, and tooth grinding, and have been linked to mouth breathing, which dries out the mouth and isn’t good for your dental health. Braces or aligners, with other appliances if needed, can not only correct a malocclusion, but prevent the very uncomfortable side effects of a bad bite.

• Improved Facial Symmetry

Malocclusions affect facial symmetry. Underbites occur when the lower jaw is too large, while small lower jaws can cause serious overbites. Bite problems can mean overjets (also called “buck teeth”), or open bites (where the front teeth don’t touch when the mouth is closed). Crossbites result in one or more upper teeth fitting inside the lower teeth. These conditions can affect both facial balance and profile.

With the use of braces and appliances like palatal expanders, Herbst® appliances, or headgear, Dr. Kathleen Chan and Dr. Ivy Chen can guide jawbone development while a child’s bones are still growing. For older patients, we can design a treatment plan to align teeth, correct malocclusion, and improve facial symmetry.

• Psychological Benefits

We can’t forget the invisible benefit of orthodontic treatment: a happy, comfortable smile is a great confidence-booster! If you’re reluctant to share your smile with the world, a visit to Dr. Kathleen Chan and Dr. Ivy Chen can let you know just what to expect from treatment, and just how it can improve your life.

Because it’s so important to both our dental health and our overall well-being, we’re happy to celebrate orthodontic health on special days throughout the year. And let’s also celebrate the fact that there’s no calendar deadline when it comes to scheduling a healthier smile! Whether it’s early treatment for younger children to guide jaw growth, or the common orthodontic treatment window during the teen years, or adult treatment to create the smile you’ve always wanted, help is available at our Andover office whenever you’re ready to set the date!

Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth that sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity that develops on one of those side surfaces of your teeth.

• Preventing Interproximal Cavities

Fortunately, prevention is about as basic as it can be—brushing and flossing effectively. Dentists recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gum line—places where bristles just can’t reach.

When you wear braces, though, flossing isn’t quite so basic. Getting that floss just where it needs to be in between brackets and wires and in between teeth can be a challenge!

The good news is there are many products designed just to make flossing easier while you’re in orthodontic treatment:

• Floss threaders are flexible hoops that help you thread floss behind your wires easily.
• Precut floss strands use a stiff tip at one end for threading floss through wires.
• Interproximal brushes are tiny, cone-shaped brushes which can fit between your teeth and braces for precise cleaning.
• Water flossers eliminate floss altogether, using a pulsing stream of water to clean between and around teeth and braces.

During your next visit to our Andover office, Dr. Kathleen Chan and Dr. Ivy Chen can give you tips on how to use any of these tools effectively for cleaner teeth and cleaner braces.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If we find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with your dental team to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.
