A popular option for straightening teeth at Kubo Orthodontic Group, Invisalign can be a great method for improving your smile, and can help patients with crowded teeth, crossbites, overbites, underbites, and more.

Invisalign, which is different from traditional braces, works by applying a series of clear, retainer-like aligners in order to eventually move your teeth into their ideal positions. Patients typically swap aligners approximately every couple of weeks.

At Kubo Orthodontic Group, we have lots of experience using this technology to give our patients the beautiful and healthy smile they’ve always wanted. During your initial visit at our Fresno, CA office, the first thing we do is take an impression of your teeth as they are now and digitize it. Using special software, we look at the current positioning of your teeth and compare it to the way your teeth should look.

Not only are the aligners invisible, they are also removable, so you can eat and drink what you want, and brushing and flossing are easier. Invisalign’s aligners are also comfortable, with no metal to cause mouth abrasions during your treatment. And, no metal and wires usually means you spend less time at our office getting adjustments. With Invisalign, you can view your own virtual treatment plan when you start, so you can see how your straight teeth will look when your treatment is complete!

Depending on the severity of the problem, Invisalign treatment may take anywhere from three to 18 months to complete. You should be aware that Invisalign is not as effective as traditional braces in treating bite problems, teeth that are lower or higher than others, or severely overcrowded teeth. Both teens and adults are now great candidates for Invisalign, so we invite you to contact our Fresno, CA office to set up an initial consultation and learn more on how Invisalign can give you the smile you’ve always wanted!

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. Robert Kubo and Dr. James Kubo 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 Kubo Orthodontic Group 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 Kubo Orthodontic Group 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 Kubo Orthodontic Group in Fresno, CA as soon as possible to make sure your child is on track for a future of healthy smiles.

X-rays have been a function of dental healthcare for a long time. That in and of itself should be good news, because it means we've had plenty of time to improve them. While there is always some risk in exposure to radiation, dental X-ray exposure has decreased significantly due to all the advances in technology. So there’s risk, but X-rays are quite safe.

Think of X-rays as you would about a car. Automobiles these days have all kinds of technology to make them as safe as possible. There's still a chance that you’ll suffer an accident. Would you stop using a car because of that risk? When it comes to dental X-rays, Dr. Robert Kubo and Dr. James Kubo and our team believe the positives clearly outweigh the negatives.

X-rays can be done digitally or with film. For film, X-rays require different exposures at different speeds to produce the image. Digital X-rays have software that automatically adjusts the exposure and produces the X-ray in a digital file. Since they substantially reduce your exposure to radiation, digital X-rays are the current standard in dental offices.

In addition to digital X-rays, lead aprons are an essential piece of X-ray safety. They help protect internal organs from X-rays by acting as a shield. They usually come with a thyroid collar as well, since that is one of the most vulnerable areas to X-rays in the body. Lead aprons can absorb up to 95% of any scatter rays that result from an X-ray. Not bad, right?

Although dental X-rays involve some radiation exposure (not all of it can be eliminated), so does everyday life. Getting too much sun, for example, can be dangerous. The truth is, we accumulate radiation in our bodies over a lifetime, so it’s worthwhile to be aware and avoid as much unnecessary exposure as possible. When it comes to your dental health, though, getting an X-ray — especially when your doctor says you need it — offers more benefits than risks.

It’s easy to reach for an energy drink when you’re feeling a bit low on, well, energy. These drinks are loaded with caffeine, and, like coffee or tea, can help you feel more alert. But before you pop that top, let’s look at how energy drinks affect your dental health.

• Energy drinks are very acidic.

Acid levels are measured using the pH scale, which ranges from 0 (most acidic) to 14 (most alkaline). Saliva has a normal pH somewhere between 6.2 and 7.6, which helps neutralize any acidic conditions in the mouth and promotes a healthy oral environment. But saliva’s neutralizing effect can be overwhelmed by highly acidic foods and drinks.

Why are higher levels of acids bad for our teeth? Acids strip away minerals like calcium from tooth enamel, minerals which make enamel the strongest substance in the body. This demineralization weakens the enamel’s protective outer structure and can lead to enamel loss, sensitivity, tooth discoloration, and decay.

Many energy drinks are among the most acidic beverages on the market. Mineral loss in your enamel starts to occur when the pH balance in the mouth falls to 5.5 or less. Lemon juice has a pH between 2 and 3. White vinegar has a pH of 2.5. Energy drinks can range from 1.5 to 3.5 on the pH scale! Studies show that regular consumption of energy drinks greatly increases the risk and severity of dental erosion.

• Most energy drinks are full of sugar.

Sugar is easily metabolized, or broken down, by the body. When our bodies break down food, energy is released. That’s why companies add sugar as well as caffeine to their energy drinks. 

The plaque bacteria which create cavities also use sugars in these drinks as an energy source, converting sugars into acids. Just like acidic foods and drinks, bacterial acids break down the mineral structure in tooth enamel. You might notice small white spots when the enamel starts to erode—and a cavity starts to develop. 

• Energy drinks aren’t just bad for your dental health. 

The temporary burst of energy you get from all the sugar in energy drinks is followed by a sugar crash when blood sugar levels go down again, and you can feel tired, weak, or shaky. 

Even worse, one energy drink might contain three to four times the amount of caffeine found in a cup of coffee. Excess caffeine interferes with healthy sleep. It can cause changes in heart rate, blood pressure, and anxiety levels. 

Children and teens are especially vulnerable to the effects of large amounts of caffeine while their brains and bodies are still developing. That’s why the American Academy of Pediatrics recommend no energy drinks at all for children and teenagers. The FDA suggests that adults should not take in more than 400 milligrams per day of caffeine, while energy drinks can range from around 80 to 400 mg per can. 

If you do have the occasional energy drink, what’s the best way to protect your teeth and gums?

• Don’t linger over your drink. Sipping slowly over time just bathes your teeth and gums in sugar and acids over a longer period. 
• Drink water when you’re done. Water helps wash away sugars and acids, hydrates, and promotes healthy saliva production.
• If the team at Kubo Orthodontic Group gives gum a thumbs up, chew a piece of sugarless gum after downing an energy drink to increase saliva flow and help neutralize acids in the mouth. 
• Wait at least 30-60 minutes to brush after finishing an energy drink. Acids in the drink weaken enamel, and brushing immediately can be abrasive to the tooth surface.
• Eat a healthy diet rich in proteins, complex carbs, vitamins, and minerals to feel more energetic.
• Keep up with good dental hygiene. Brush twice each day for two minutes and floss daily, or more often as recommended by Dr. Robert Kubo and Dr. James Kubo.

If you notice signs of enamel erosion—sensitivity, front teeth which are becoming transparent or rough around the edges, yellowish discoloration, or white or brown spots on your enamel—it’s time for a talk with your dentist. When caught early enough, treatment is available which can stop further erosion from harming your teeth.

It can be harder to brush and floss as effectively when you wear braces, so it’s more important than ever to make healthy choices in your diet and to keep up with your dental hygiene. The team at Kubo Orthodontic Group in Fresno, CA is always happy to give hygiene tips! Talk to your dentist or doctor to discover healthy ways to stay focused and energetic. Your workout, your essay, your rehearsal, and, above all, your healthy body and healthy smile will thank you!
