Which Retainer is Right for You?

May 18th, 2022

Brackets and wires, clear aligners, lingual braces, regular brackets, self-ligating braces, elastics, spacers—you and your orthodontist have had to narrow down a lot of choices to discover the best treatment for your orthodontic needs. Now that the end of treatment is in sight, there’s one more important choice left—your retainer!

Do I Need a Retainer?

No retainer at all is probably the one option that’s off the table from the start. It’s not just your teeth that have changed position; it’s the bone and ligaments holding them that have changed as well.

A retainer prevents your teeth from moving away from their new, ideal location while your bones and ligaments are stabilizing. This process takes months, so keeping your teeth in place as your bone rebuilds and regains density is crucial.

What Are Your Retainer Options?

Three of the most popular retainer options available at our Fresno, CA office include:

  • Hawley Retainers

This is the traditional retainer, with wires to hold your retainer in place and to keep the teeth properly aligned. The wires are attached to an acrylic plate molded to fit the roof of your mouth or around your bottom teeth. You can customize the acrylic base with colors and patterns for a one-of-a-kind look.

Hawley retainers are adjustable, so minor realignments can take place if necessary. The wire in front of your teeth makes these retainers visible, but, after several months of wearing them all day long, you may end up wearing them only at night.

Hawley retainers are removable, so you need to make sure they are safely in a case when you’re not wearing them. Minor damage can often be repaired, but it’s better to be proactive.

  • Clear Plastic Retainers

These retainers look like clear aligners. They are formed by heating a thin piece of plastic and vacuum-forming it around a model of your teeth to create a custom, comfortable fit.

Clear retainers are almost invisible when worn, and can be removed when you eat or drink—which they should be, because food particles and liquids can be trapped inside them.

When you’re not wearing it, a clear retainer should always be in its case, because it must be replaced if the plastic is warped, cracked, or broken.

  • Fixed Retainers

A fixed retainer is a small single wire bonded to the back of specific teeth, commonly the six bottom front teeth. Because fixed retainers don’t allow the teeth to move at all, they are often recommended for patients who had serious misalignments, extremely crowded teeth, or teeth with large gaps between them.

Many patients like fixed retainers because they keep teeth in perfect alignment, they won’t be seen, they’re comfortably small, and they can’t end up in the cafeteria recycling bin because you forget to replace them after lunch!

Fixed retainers are usually quite durable, but you’ll need to pay attention to your diet, because crunchy and chewy foods can put pressure on the retainer and damage it. These retainers also require special care with brushing and flossing, to make sure the teeth bonded to the wire stay clean and plaque-free.

The Right Retainer

The process of stabilizing your teeth in the jaw takes time. Choosing your retainer will depend in part on how long and how often you need to wear it: fulltime for months or for years, at night after several months of day-and-night wear, or long-term to make sure your orthodontic work lasts.

And there are other variables, as well. Your retainer might need to be removable. It might need to be adjustable. You might need a retainer for just your upper teeth, just your lower teeth, or both. All these factors and more need to be taken into consideration before deciding on your ideal retainer.

Fixed, removable, wire, plastic, colorful, clear—which retainer is right for you? The one that helps you retain the beautiful smile you’ve worked for all these months. Talk to Dr. Robert Kubo and Dr. James Kubo to discover the retainer that will protect that smile for years to come.

The Twin Block Appliance

May 11th, 2022

Orthodontic treatment involves a lot more than just straightening your teeth. For a healthy smile, your bite must be healthy as well! This means that the upper and lower jaws need to fit together properly and comfortably.

If your bite is out of alignment because of jaw misalignment, orthodontic treatment can help correct the shape and position of your jaws with devices called functional appliances. These appliances are most often used for young patients whose bones are still growing, and are designed to treat malocclusions, or bite problems.

Common malocclusions such as overbites and overjets can occur when the upper teeth protrude further than they should, or the lower jaw is positioned too far back, or both. The Twin Block appliance can be used in such cases to help move your lower jaw and teeth into alignment with your upper jaw.

Why “Twin”? Because the Twin Block appliance is two separate pieces, each made of wire and smooth acrylic. Both pieces are crafted to fit precisely over your upper and lower arches and can be adjusted as your treatment progresses. The top plate can also be adjusted, if necessary, to widen the upper palate.

Why “Block”? Acrylic blocks cover the biting surfaces of several of your upper and lower teeth. These blocks fit together like a 3D puzzle. When you bite down, the upper blocks interlock with the lower blocks, pushing the lower blocks forward just a bit before you can bite down completely. Over time, bit by bit (and bite by bite), the Twin Block appliance advances your lower jaw and teeth to create a balanced, comfortable bite.

For the quickest and best results, you should wear your Twin Block appliance as directed. It’s made to be worn comfortably while you sleep, eat, and otherwise go about your day. (It’s a good idea to check with our Fresno, CA orthodontic team to see about removing it when you’re active, especially for swimming and contact sports.) When it’s time to brush, the Twin Block appliance is removable. This means that you can clean your teeth and your appliance easily.

And, while it’s made to work hard for you, it’s not indestructible. Don’t expose your appliance to heat or hot water, as the plastic may warp. Use the cleaning methods we recommend. Finally, when your appliance is out of your mouth, keep it in its case! You don’t want your appliance to end up carefully wrapped in a napkin in the nearby recycling bin. Or, even worse, in your dog’s mouth instead of yours.

The Twin Block appliance might fit together like a puzzle, but there’s nothing puzzling about how to achieve your best and fastest results. Your success really depends on you. Follow Dr. Robert Kubo and Dr. James Kubo and our team’s advice, wear your appliance as directed, and you’ll be on your way to a healthy, comfortable bite and an attractive, confident smile!

May Marks National Physical Fitness and Sports Month!

May 4th, 2022

The merry month of May also happens to be National Fitness and Sports Month, so take advantage of the warmer days to get outside and exercise! Bringing a friend, family member, or coworker with you when you go for a brisk walk during a lunch break can provide an opportunity to socialize as well as health benefits. If you need a little more motivation, here are some good reasons to stay active and fit.

Exercise provides:

  • Improved stamina and energy as well as toned muscles and bone strength and density
  • Improved circulation and breathing for a healthier heart and lungs
  • Reduced risk for Type 2 diabetes and certain forms of cancer
  • For older adults, regular exercise may help improve balance and reduce the risk of falls as well as improved cognitive abilities

Children and Teens

Children and teenagers spend long hours at their desks in school, on the computer, watching television, and involved in other sedentary activities that result in obesity and poor health later in life. Getting them engaged in school or community sports teams can help them form good life-long exercise habits. One important note: If they are participating in contact sports, Dr. Robert Kubo and Dr. James Kubo and our team at Kubo Orthodontic Group recommend your kids wear an approved mouthguard to protect those valuable teeth from injury! Ask us for a proper fitting of your safety appliance during your next visit!

A gym membership is nice but not necessary to stay fit; try these easy ways to work some exercise into your daily routine.

At Home

  • Take a friend along for company on a walk through your neighborhood.
  • Pursue gardening or other yard work, including mowing or raking.
  • Take your kids on a bike ride or have them push a baby stroller around the block.

Couch potatoes take note: simply moving from the sofa to the floor for some sit-ups, leg-lifts, or push-ups while you’re watching television can help you get in better shape in no time.

At Work

  • Take the stairs instead of the elevator.
  • Take exercise breaks for walks around the building or parking lot.
  • Walk or ride a bike to work.

So what are you waiting for? Get moving!

When Your Smile Isn’t Aging as Gracefully as You Are

April 27th, 2022

You might have been one of the lucky few born with perfectly straight teeth and a healthy bite. You might have spent months in orthodontic treatment as a teenager to achieve perfectly straight teeth and a healthy bite. But now that you’re growing older, you might be unhappily surprised to discover that your smile isn’t aging as gracefully as you are.  What’s changed?

That’s a trick question, because our bodies never stop changing, growing, and adapting. And these constant adjustments include the changes taking place in your teeth and mouth. You might begin to notice subtle differences in your smile when you’re in your thirties or forties. After young adulthood, several factors come into play which can cause shifting teeth and a misaligned bite:

  • Teeth naturally shift.

Shifting can be a result of the normal changes time brings. The periodontal ligaments which attach our teeth firmly to the jawbone lose some of their strength; the jawbones which hold our teeth in place lose some of their density and begin to narrow. Our teeth also have a natural tendency to move toward the front of the mouth, a phenomenon called “mesial drift.”

Add all of these elements together, and your once straight teeth start to crowd together and even overlap—especially the front bottom teeth.

  • Stressful habits stress your teeth.

If you habitually grind or clench your teeth, you’re putting pressure on them. Just like the gentle pressure of braces and aligners can shift teeth into alignment, the more uncontrolled force of grinding can push teeth out of alignment.  

  • Losing a tooth affects surrounding teeth.

Nature abhors a vacuum, and so does your smile. If you lose a tooth, your other teeth will automatically start to drift into the space left open by the missing tooth.

  • A neglected retainer is gathering dust in a drawer somewhere.

You might have spent time as a teenager in orthodontic treatment, with a beautiful smile to show for all your hard work. And, back in the day, your orthodontist no doubt let you know that you needed to keep wearing your retainer at night once your treatment was completed.

If that’s one healthy habit you abandoned as you got older, don’t be surprised if your teeth start to migrate back to their old, less-than-perfect positions.

Between normal biological changes and the wear and tear of daily life, you might find one day that your smile isn’t that same beaming smile you’re used to seeing in the mirror. And it’s not just an aesthetic concern.

Crooked teeth are harder to clean, and built-up plaque means more decay and gum disease. Shifting teeth can cause malocclusions, or bite problems, which can bring you jaw pain, headaches, and chipped or cracked teeth.

If your smile has changed over time, it’s time to give Dr. Robert Kubo and Dr. James Kubo a call. There are many discreet options which can return your smile to you, including:

  • Clear aligners—comfortable, removable, and often unnoticeable.
  • Traditional braces—brackets are smaller than ever, and you can choose ceramic brackets which are color-matched to blend in with your enamel.
  • Lingual braces—these braces are attached to the inside of the teeth, for complete invisibility.

And what if you’ve never been as confident in your smile as you wanted to be? There’s good news here as well—it’s never too late to see an orthodontist. Make an appointment at our Fresno, CA office to discover how you can make sure your smile looks just as young as you feel!
