DietDosandDontsforOralHealth

What and how you eat and drink has a significant impact on the health of your teeth and gums. Therefore, an effective oral hygiene regime must take your diet into account.

Acid is your teeth's enemy; it can erode their protective enamel coating (a process called demineralization). Certain foods and beverages (such as citrus drinks and coffee) contain it, and it's produced by bacteria in your mouth that feed on dietary sugar and release acid as a byproduct (a process called fermentation). Your allies are foods and beverages that neutralize acids, provide minerals and vitamins to repair tooth enamel, and stimulate saliva.

Sugar & Decay
Sugars, the leading promoter of dental decay, exist in many forms in our diet. Some occur naturally, while others — referred to as “free sugars” — are added by the manufacturer, cook or consumer. The latter are most often linked with decay. Soft drinks are the primary source of dietary free-sugars in the U.S.

Sugars in fruit, vegetables, milk and unprocessed, starch-rich foods such as rice, potatoes and whole grains, do not appear to be harmful to teeth. Note, however, that dried fruits contain a highly concentrated sugar level and can stick to tooth surfaces. The sugar substitutes xylitol and sorbitol appear not to promote decay. In fact, there's evidence that chewing xylitol-sweetened gum three to five times daily for at least five minutes (after meals) stimulates saliva flow, which helps protect against decay.

Acids & Erosion
In addition to eroding tooth enamel, acidic foods and beverages create an environment where it's easier for decay-promoting bacteria to flourish. Saliva can reduce acidity but it must have time to work, at least 30–60 minutes. That's why behaviors that maintain acid levels, such as sipping coffee throughout the day, can be harmful.

Saliva-Promoting Saviors
Saliva is a front-line defense against erosion and decay. It helps remove food particles and contains minerals that help neutralize acid and promote remineralization of the tooth surface. Foods that stimulate saliva and/or contribute essential minerals include:

  • Cheese — stimulates saliva and is rich in calcium, contributing to the re-calcification of teeth and protecting against the loss of calcium,
  • Cow's milk — contains decay-counteracting calcium, phosphorous and casein,
  • Plant foods — are fibrous and require chewing, which mechanically stimulates saliva,
  • Water — keeps you hydrated, which is important for saliva production and preventing dry mouth (a condition that promotes acid-producing bacteria), and helps wash away food particles; fluorinated water bestows the protective properties of fluoride (a compound that makes tooth enamel more resistant to acid erosion and promotes re-calcification).

As you can see, brushing and flossing effectively is just part of the oral hygiene equation.

CosmeticDentistryandtheUrbanLegend

He once lived in Australia, wore his hair in a mullet, and played guitar in a band called The Ranch. Today, country music star Keith Urban looks different than he did when he started out — and it’s not just the mullet that’s changed. As before-and-after pictures show, he’s had a smile makeover. His teeth, which were dull yellow in color, and used to have a large gap in front, are now white and shiny. The gap is still there — though it has been reduced to a more modest size. How did he manage to upgrade his image, yet keep part of his signature “look” intact?

Cosmetic dentistry has a number of ways to improve the appearance of a smile like Keith’s. One is tooth whitening. It’s a simple procedure that can be done in our office or at your home; either way, it’s an effective treatment that offers great value. In-office whitening, using the most concentrated solutions under our direct supervision, will give you the fastest results. We can also prepare a take-home kit, with custom-made trays and safe bleaching gels you can use at home. You’ll get similar results, but it will take a bit longer.

Of course, whitening isn’t permanent (though it can be repeated when necessary); not all teeth can be lightened as much as you might like; and it doesn’t correct gaps or unevenness. There’s another treatment that does, however: dental veneers. These are wafer-thin coverings made of porcelain, which are bonded to the prepared surfaces of your teeth. They are available in a number of shades — from natural to “Hollywood white” — and can even hide minor chips or spacing problems. That’s why veneers are often the treatment of choice when you’re looking for a “red carpet” smile.

Perhaps the best thing about veneers is that they give you plenty of choices when it comes to designing your smile. You can choose how white you’d like your smile to be, and even fix some “flaws” — or not! So how much you choose to close that gap in your teeth is up to you… but if you’re asking our opinion, the mullet has to go.

HelpYourMouthsAbilitytoFightToothDecayWithBetterHygieneandDiet

Your teeth have enemies — bacteria that feed on biofilm, a thin layer of food remnant known as plaque that sticks to your teeth, are one such example. After ingestion, these bacteria produce acid, which can erode your teeth’s protective enamel and lead to tooth decay.

Fortunately, you have a weapon against enamel loss already at work in your mouth — saliva. Saliva neutralizes high levels of acid, as well as restores some of the enamel’s mineral content lost when the mouth is too acidic (re-mineralization).

Unfortunately, saliva can be overwhelmed if your mouth is chronically acidic. Here’s how you can help this powerful ally protect your enamel and stop tooth decay with better hygiene and eating habits:

Remove bacterial plaque daily. You should floss and brush with fluoride toothpaste everyday to remove plaque. It’s also recommended that you visit us twice a year for professional cleanings to remove hard to reach plaque. We can also train you on how to properly floss and brush.

Wait an hour after eating to brush. It may sound counterintuitive, but brushing immediately after you eat can do more harm than good. The mouth is naturally acidic just after eating and some degree of enamel softening usually occurs. It takes a half hour or so for saliva to restore the mouth’s pH balance and re-mineralize the enamel. If you brush before then, you may brush away some of the softened enamel.

Limit sweets to mealtimes. Constantly snacking on sweets (or sipping sodas, sports or energy drinks) will expose your teeth to a chronic high level of acid — and saliva can’t keep up in neutralizing it. If you can’t abstain from sugar, at least limit your consumption to mealtime. It’s also a good habit to rinse out your mouth with clear water after drinking an acidic drink to flush out excess acid.

Boost saliva content with supplements. If you suffer from insufficient saliva production or dry mouth, try an artificial saliva supplement. Chewing xylitol gum can also help boost saliva production, as well as inhibit the growth of infection-causing bacteria. We’ll be glad to advise you on the use of these products.
