Positioned for Success

August 10th, 2023

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. Robert Kubo and Dr. James Kubo 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. Robert Kubo and Dr. James Kubo 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. Robert Kubo and Dr. James Kubo 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 Fresno, CA office. A positioner could be an effective, time-saving step on your path to a lifetime of healthy smiles.

What causes crooked teeth?

August 2nd, 2023

Crooked teeth, more correctly called malocclusions, have reached epidemic proportions in the late 20th and early 21st centuries. According to the American Association of Orthodontists, approximately 80 percent of American teenagers are currently undergoing orthodontic treatment. Although advances in orthodontic devices and increased availability of such devices explain part of this increase, it still means there are a lot of crooked teeth in the world.

The theories about what is causing so many crooked teeth range from the ridiculous to the scientific. For years, oral health professionals believed that crooked teeth were an evolutionary result of the change in Western diets from raw, wild foods to soft, processed foods. That theory has since been debunked.

The truth is that crooked teeth can be caused by a number of things. Crooked teeth can be an inherited trait. Parents with crooked teeth and malformed jaws are more likely to have children with malocclusions. Ill-fitting or poorly-executed dental restorations, such as fillings and crowns, can also cause teeth to become crooked. Baby teeth that fall out early, gingivitis, and even a jaw that is too small to accommodate all of a person’s adult teeth are additional causes of crooked teeth. In addition, thumb sucking and the use of a pacifier for too long can contribute to crooked teeth.

What to do about crooked teeth

Fortunately, modern orthodontics offers a number of solutions for crooked teeth. Traditional metal braces are the most popular, though our Fresno, CA office provides a number of clear, aesthetic options as well. If you’re tired of hiding your smile because of crooked teeth, contact Dr. Robert Kubo and Dr. James Kubo and our team at Kubo Orthodontic Group and set up an appointment. We’ll have you showing off your straight pearly whites in no time!

Why Do I Need a Retainer?

July 27th, 2023

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. Robert Kubo and Dr. James Kubo 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. Robert Kubo and Dr. James Kubo 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. Robert Kubo and Dr. James Kubo 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 Fresno, CA team about which retainer option will be best for making sure that this smile lasts a lifetime.

What is a water pick and do I need one?

July 19th, 2023

Water picks, sometimes called “oral irrigators,” make an excellent addition to your regular home care regimen of brushing and flossing. Especially helpful to those who suffer from periodontal disease and those patients of ours undergoing orthodontic treatment with full-bracketed braces, water picks use powerful tiny bursts of water to dislodge food scraps, bacteria, and other debris nestled in the crevices of your mouth. Children undergoing orthodontic treatment may find using a water pick is beneficial if their toothbrush bristles tend to get caught on their wires or brackets.

When you use a water pick, you’re not only dislodging any particles or debris and bacteria you might have missed when brushing, you are also gently massaging the gums, which helps promote blood flow in the gums and keeps them healthy. While water picks are an excellent addition to your daily fight against gingivitis and other periodontal diseases, they are incapable of fully removing plaque, which is why Dr. Robert Kubo and Dr. James Kubo and our team at Kubo Orthodontic Group want to remind you to keep brushing and flossing every day.

If you have sensitive teeth or gums and find it uncomfortable to floss daily, water picks are a good alternative to reduce discomfort while effectively cleaning between teeth. Diabetics sometimes prefer water picks to flossing because they don't cause bleeding of the gums, which can be a problem with floss. If you have a permanent bridge, crowns, or other dental restoration, you may find that a water pick helps you keep the area around the restorations clean.

So how do you choose the right water pick?

Water picks are available for home or portable use. The home versions tend to be larger and use standard electrical outlets, while portable models use batteries. Aside from the size difference, they work in the same manner, both using pulsating water streams. A more crucial difference between water picks is the ability to adjust the pressure. Most home models will let you choose from several pressure settings, depending on how sensitive your teeth and gums are. Most portable models have only one pressure setting. If you want to use mouthwash or a dental rinse in your water pick, check the label first; some models suggest using water only.

Please give us a call at our Fresno, CA office if you have any questions about water picks, or ask Dr. Robert Kubo and Dr. James Kubo during your next visit!
