KeepYourSalivaFlowing-YourOralHealthDependsonit

We often don't realize how important something is until it's gone. Like saliva: you're usually not aware that it's cleaning the mouth, neutralizing mouth acid or helping with digestion. But that could change if your saliva flow drops below normal: your health may soon suffer with your mouth taking the brunt.

In particular, reduced saliva flow increases your risk for tooth decay and periodontal (gum) disease. Both diseases are linked to oral bacteria. While many of the myriad strains in the mouth are beneficial, a few bacteria can infect and inflame gum tissues. Bacteria also produce acid, which can soften and erode enamel and make the teeth more susceptible to decay.

Saliva inhibits bacteria in a number of ways. It first clears the mouth of leftover food so not as much stays behind to form bacterial plaque, a thin film of food particles that builds up on teeth. You still need to brush and floss daily to remove plaque, but it's less effective without saliva's cleansing action. Saliva also contains antibodies that destroy disease-causing bacteria and other organisms, which keeps their populations in the mouth low.

One of saliva's most important functions, though, is buffering acid. The mouth's ideal pH level is neutral, but many foods we eat can cause it to become more acidic. Even a slight acidic rise after eating can soften the minerals in enamel. But saliva goes to work immediately and usually restores normal pH within a half hour to an hour. It also aids in re-mineralizing the enamel.

For these reasons, it's important for you to find out the cause of chronic dry mouth and treat it. If it's a side effect of your medication, talk to your doctor about an alternative, or drink more water before and after you take your dose. Certain products can also stimulate saliva flow, like chewing gum with xylitol, an alcohol-based sweetener that has dental health-protecting properties too.

Although you often don't notice this unsung bodily fluid swishing in your mouth, it's important that you take care of it. Keeping your saliva flowing will help ensure better oral health.

FifthHarmonysCamilaCabelloChipsaToothbutConcertStillWorthIt

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand. Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.

Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.

A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.

Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.

If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.

If you have questions about smile restoration, please contact us and schedule an appointment. You can read more in the Dear Doctor magazine articles “Porcelain Veneers: Strength & Beauty As Never Before” and “Porcelain Crowns & Veneers.”

AvoidPermanentToothAlterationwithNo-PrepVeneers

Porcelain veneers have become a popular way to transform a smile. They're ideal for stained, chipped or slightly misaligned teeth. But although they don't need as much tooth preparation as crowns or other bridgework, the traditional veneer still requires some permanent tooth alteration.

Now, there's an alternative: no-prep veneers. With this option we can avoid any tooth structure removal or keep it to a minimum. And it may not even require local anesthesia while applying them.

Veneers are as their name implies: a wafer-thin layer of tooth-colored porcelain that's bonded to the outside of a tooth, much like siding on a house. Although the traditional veneer is usually no more than a millimeter in width, they can still add an unnatural bulky look and feel to a tooth. To compensate, we remove portions of the enamel. A tooth permanently altered this way will henceforth require some form of restoration.

No-prep veneers are much thinner; they also don't extend under the gum line like traditional veneers. At the most the new veneers may only require us to perform some minor reshaping of the enamel, but not to the extent of traditional veneers. And because your tooth isn't permanently altered, we could presumably remove the veneer and return the tooth to its natural state and appearance (although removing the bonding might not be that easy).

There are some situations where some tooth alteration may still be necessary, like oversized or forward-jutting teeth. A bad bite (malocclusion) may require orthodontic treatment first — which in some cases could be an alternative treatment to veneers altogether.

To find out if you're a candidate for no-prep veneers, visit us for a complete examination. From there we can discuss your options and whether we can transform your smile with little change to your teeth.

How your dentist in Honolulu can help your smilecosmetic bonding

Do you hide your smile because of chipped or broken teeth? Do you avoid eating hard foods because your teeth are badly worn? Do you want a more beautiful smile? If you answered yes to any of these questions, it’s time to learn about cosmetic bonding, one of the most versatile cosmetic treatments available. Dr. Ken Yasuhara in Honolulu, HI, wants to help you discover how cosmetic bonding can do wonders for your teeth.

Cosmetic bonding is the perfect choice to fix teeth that are:

  • Cracked or chipped from trauma
  • Broken from an accident or injury
  • Discolored from medications, coffee or smoking
  • Excessively worn down from a bad bite
  • Poorly shaped due to genetics

Dental bonding has many advantages when compared to other cosmetic dental treatments. When you choose dental bonding, you can count on natural-looking results because the bonding material, called composite, can be color-matched perfectly to your existing teeth. The bonded area will be virtually indistinguishable from your natural teeth, giving you a uniform, harmonious smile. Other advantages include:

  • No need for anesthetic in most cases
  • Lower cost when compared to other cosmetic treatments
  • Quick, comfortable treatment

Your cosmetic bonding treatment begins with the application of an etching gel, which creates small, pore-like openings in the surface of your tooth. Next, a bonding cement is applied, which creates a strong attachment of the bonding material to your tooth.

The composite bonding material is a liquid resin which can be molded and sculpted into contours to reshape your tooth beautifully. The resin is then hardened with a high-tech ultraviolet “curing” light. As a final step, your cosmetic bonding treatment is shaped and polished to a sparkling sheen.

Cosmetic bonding can do wonders for your teeth, restoring full chewing function and giving you back your beautiful smile. Don’t put up with an embarrassing smile when help is just a phone call away. For more information or to schedule a consultation, call Dr. Yasuhara in Honolulu, HI, today!

ActressEmmaStoneRevealsHowThumbSuckingAffectedHerTeeth

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.

“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”

While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)

When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.

Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.

But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.

Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award! Does your child have a thumb sucking problem or another harmful oral habit? For more information about how to correct it, please contact us or schedule an appointment for a consultation.
