As you near the end of your orthodontic treatment, you’re probably already imagining the day when your brackets and wires finally come off. Or the moment you’ve finished with your last set of aligners. That day might come just a bit sooner if Dr. Kathleen Tavarez and our team recommend a positioner.

While not as well-known as other orthodontic treatments, a positioner is an appliance that can shorten your time in traditional braces and aligners by weeks or even months. Curious? Read on!

• What Exactly Is a Positioner?

A positioner resembles a clear mouthguard. Its arched shape is designed to fit snugly over your teeth. It’s sometimes called a finishing appliance, because it’s designed to make those last small adjustments to your alignment and bite. If you’re a good candidate for a positioner, it can replace your braces or aligners for your last several weeks or months of treatment.

• How Are Positioners Made?

This appliance is custom fabricated to fit your very specific orthodontic needs. Commonly, a mold is made of your teeth. A model of your teeth is made from this mold. Precision instruments are used to move the model teeth into your ideal alignment.

Once this model of your future finished smile is complete, it is used to create the positioner. When the thermoplastic material is molded to the model, it creates an appliance with an indentation for each individual tooth in its desired final location.

Available in a variety of materials, a positioner is most often designed as a clear single piece, covering both your upper and lower teeth. This makes sure that your teeth are not only aligned properly, but that your upper and lower teeth are working together for a healthy bite. Openings in the positioner provide airways which allow you to breathe easily.

• How Do Positioners Work?

Because your teeth haven’t settled firmly into place yet (this will happen as you wear your retainer), they’re still able to move. That’s why your positioner is shaped to fit your teeth in their future ideal placement, not where they are at present.

Positioners require your active participation. Your teeth move to the ideal spots molded into the positioner through “exercise”—biting down on your appliance for 15-20 seconds before relaxing your bite, usually every 10-15 minutes during your daily wear. The gentle force provided by your jaw muscles helps guide your teeth into position more quickly. Dr. Kathleen Tavarez will give you instructions on just how to—and how often to—do these exercises.

• How Long Are They Worn?

Positioners are commonly worn at least four hours a day to start with and all night long, or Dr. Kathleen Tavarez might recommend 24 hour a day wear for the first week. As you progress, you’ll wear them for shorter periods during the day, gradually tapering off until your treatment is complete.

Depending on the amount of correction that’s still needed, positioner use ranges from several weeks to several months. One thing that will ensure that your time in a positioner is as short as it can be is your willingness to follow our instructions. The speed and effectiveness of your final tooth movements is largely up to you!

• Caring for a Positioner

Gentle treatment is best. Clean your positioner before and after wearing it using a toothbrush and mild toothpaste. Never boil it or expose it to heat. We will give you instructions for how to clean it more thoroughly, if needed.

Like retainers, clear aligners, and mouthguards, a positioner needs to be protected when it’s not in your mouth. Your positioner will come with a case, so be sure to use it!

Positioners aren’t recommended for every orthodontic patient. But if you feel this might be an option worth pursuing, talk to us when you visit our Menlo Park or San Carlos, CA office. A positioner could be an effective, time-saving step on your path to a lifetime of healthy smiles.

It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in an orthodontic blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally raise concerns about tooth misalignment, especially when those extra teeth are molars. If double molars are causing crowding, it’s a good time for your child to have an orthodontic examination at our Menlo Park or San Carlos, CA office to make sure the permanent teeth are properly positioned.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call Dr. Kathleen Tavarez for expert advice.

When you’re busy at school or work, when you’re on vacation, when you’re on the road to adventure—preparation helps everything go smoothly. Especially when the unexpected happens! So, how can you be prepared for any orthodontic and dental situations which might arise? By creating these useful—and portable—travel kits.

Everyday Basics Kit

Dentists recommend brushing twice a day and flossing at least once each day for clean and healthy teeth. But after a long day at school or work with no time to head home before your date, or a garlic-heavy lunch in the cafeteria, or a dash from the classroom to after-school activities, you might feel like there’s no time like the present to give your smile a bit of a boost.

Be prepared with a small travel bag filled with these easy-to-carry basics to get you through your busy day with clean teeth, fresh breath, and a confident smile:

• Toothbrush and case—and do make sure your case is ventilated so your brush can air dry. Bacteria love a closed, damp environment!
• Toothpaste
• Mini-bottle of mouthwash
• Small mirror—to check for any lunch leftovers
• Dental floss—to remove any lunch leftovers. Use braces-friendly dental floss if you have traditional braces.
• Dental Wax—to cover any uncomfortable wires or brackets
• Interproximal brushes—to remove food particles from around your braces and between your teeth
• Extra rubber bands
• Aligner/Retainer case—keep your aligner or retainer safe and clean while you’re eating

Flight Gear

Getting set to travel by air again after this long lay-over? Your basic kit will do the job with just a few minor additions and alterations.

• A travel version of your manual or electric toothbrush and travel case
• Plug adapter or voltage converter as needed for your electric brush if you’re visiting another country
• Quart size, resealable plastic bag to hold your carry-on supplies. Toothpaste and mouthwash are included in the list of items which need to fit carry-on guidelines.
• Travel-size toothpaste—3.4 oz (100 ml) or smaller tube size. (And an almost-empty regular size tube doesn’t count!)
• Travel-size mouthwash—also in a 3.4 oz (100 ml) or smaller container
• Our Menlo Park or San Carlos, CA office’s phone number. In case of emergency, Dr. Kathleen Tavarez can give you advice on how to handle any problem which might arise when you’re far from home.

Looking for Adventure?

If you’re camping in the forest, leaving for the lake, going for a road trip, or heading out on any travel adventure, you’ll be bringing the dental care basics, of course. We’d also like to recommend some items to take along in the event of a dental emergency while you’re away from home:

• Dental mirror
• Cotton rolls
• Over-the-counter pain relief—including a tube of oral pain relief gel
• Ice pack
• Dental wax—this handy item not only protects against sharp wires, it can cover the sharp edges of a broken bracket
• Temporary fillings—to protect your sensitive tooth if a filling or crown is lost
• Tooth preservation kit—to protect a dislodged tooth in case it can be reimplanted. (This means seeing a dentist very quickly, usually within 30 minutes of the accident.)

And, if you’ll be mountain biking, water skiing, or enjoying any activity where there’s potential for impact, don’t forget to pack your mouthguard!

Preparation is key to eliminating a lot of stress in our daily lives, and who couldn’t use a bit of stress-relief these days? Make room in your bag, locker, desk, luggage, or backpack for some portable, lightweight dental necessities. Be prepared to share your confident, healthy smile no matter what life has in store!

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 Menlo Park or San Carlos, CA office, Dr. Kathleen Tavarez 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.
