Xylitol is a naturally occurring sweetener found in tree bark, plants, fruits, and vegetables. The human body also produces it in small amounts. It looks and tastes like sugar, so as part of a health regimen, most people require no willpower to use it.

Xylitol is safe (approved by the World Health Organization) because only a small amount is needed for health benefits. With a glycemic index of seven, it is safe for diabetics. It has less than three calories per gram and 40% fewer calories than other carbohydrates. If eaten in extremely large amounts too quickly, it has a laxative effect in humans.

Tooth decay happens when bacteria in your mouth consume the sugars you eat. When you eat food that contains ordinary sugar, it gives energy to the bacteria on your teeth, allowing them to multiply and start making acids that destroy the enamel on the teeth.

Since xylitol is a natural sweetener derived from the fibrous parts of plants, it does not break down like sugar, so it helps maintain a neutral pH level in the mouth. Xylitol also prevents bacteria from sticking to the teeth because they are unable to digest it. That is how it protects the teeth from cavities.

With xylitol, the acid attack is diminished. With less bacteria and acid, your teeth stay healthier. The frequency of xylitol ingestion is important: aim for five grams a day, or one gram every three hours.

Studies of xylitol use as either a sugar substitute or a small dietary addition have demonstrated a dramatic reduction in new cavities. It has also stopped and even reversed some existing cavities. This effect is long lasting and possibly permanent. Low cavity rates persist even years after the trials have been completed.

Xylitol needs to be one of the first ingredients in a product to be effective. It is convenient and easy to use. You can find it in health food stores and specialty grocery stores. Xylitol can be delivered to your teeth in chewing gum, tablets, or even candy and mints.

It also comes in toothpaste, mouth rinse, baby oral wipes, gel and pacifiers, nasal wash, dry mouth spray, a granulated form for cooking, granulated packets to add to drinks, and commercially prepared foods. It can replace sugar on a one-to-one ratio.

Sweet rewards in xylitol are good for the body and the teeth! If you have specific questions please feel free to contact Just 4 Kids Pediatric Dentistry. We look forward to seeing you soon!

Why all the fuss about fluoride? Your pediatric dentist recommends it, your child’s toothpaste is formulated with it, and most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

1. Fluoride Works!

Fluoride is an attractive option for protecting your child’s teeth—and we mean that literally. Fluoride protects the surface of teeth by working on a molecular level to attract minerals that strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions which are found in our saliva to restore any minerals which have been lost. This process helps repair any weak spots which might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals. Even better? These new crystals are more resistant to acids.

2. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride is important for baby teeth, as fluoride joins with minerals in adult teeth while they grow and develop. This creates stronger, more cavity-resistant teeth even before they erupt.

When your child’s permanent teeth come in, fluoride is still at work! When your child drinks fluoridated water, they increasing the amount of fluoride in their saliva. Just like fluoride toothpaste, saliva bathes the teeth with fluoride ions, remineralizing and strengthening the tooth surface and helping repair weak spots in enamel.

3. It’s Easy to Get Fluoride Protection

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride in our diet each day. If your community’s water is low in fluoride, Dr. Wendy Tang and Dr. Amy Bellamy can help you. Prescription fluoride rinses, gels, supplements, and other treatments are available at our Surrey, BC pediatric dental office to make sure that your child’s teeth are well protected, wherever you may live. We will let you know which products are best for your child and how often to use them.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. And sealants provide long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter that’s simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

Many varieties of fillings are available at our Surrey, BC office. Most people are familiar with traditional amalgam fillings: those big silver spots on top of teeth.

Made from a mixture of silver, tin, zinc, copper, and mercury, amalgam fillings have been used to fill cavities for more than 100 years. They offer several advantages, including:

• High durability for large cavities or cavities on molars
• Quick hardening time for areas that are difficult to keep dry during placement
• Reduced placement time for children and special-needs patients who may have a difficult time keeping still during treatment

Although dental amalgam is a safe and commonly used dental material, you might wonder about its mercury content. You should know that when it’s combined with the other metals, mercury forms a safe, stable material.

The American Dental Association, U.S. Centers for Disease Control and Prevention, U. S. Food and Drug Administration, and World Health Organization all agree that based on extensive scientific evidence, dental amalgam is a safe and effective cavity-filling material.

White Fillings

Newer, mercury-free, resin-based composite fillings (white fillings) are also available at our Surrey, BC office. Composite resin fillings are made from plastic mixed with powdered glass to make them stronger.

Resin-based fillings offer several benefits for patients, including:

• They match the color of teeth
• Less tooth structure needs to be removed than with amalgam fillings
• BPA-free materials can be used

Resin-based composite fillings also have some disadvantages, including:

• Higher cost than amalgam fillings
• Inlays may take more than one visit
• Requires more time to place than amalgam fillings

There’s a lot to think about when you have to get a cavity filled. We recommend you do your homework and speak with Dr. Wendy Tang and Dr. Amy Bellamy before deciding what’s best for you or your family.

Kids are constantly active and constantly growing. No wonder they’re constantly hungry! When it’s time for a snack, here are some tips to make between meal treats timely, tasty, and tooth-friendly.

Keep snacks to a minimum

Every time we eat, we’re also providing food for the bacteria in our mouths. Bacteria use sugars to produce acids. These acids weaken our enamel and can lead to cavities. Luckily, we have a natural way of protecting our teeth. Saliva washes away food particles and bacteria, and even provides substances that strengthen our teeth in the hours between meals.

When we eat throughout the day, there is no chance for this recovery period to take place. Small children aren’t usually able to get through the day without a few snack periods, which is perfectly normal. Just try to make sure that snacking doesn’t become all-day grazing!

Avoid foods that contain sugar and carbohydrates at snack time

We know that sugar leads to an increased chance of cavities because bacteria convert this sugar into acids that damage our enamel. But carbohydrates should also be in the no-snack zone. Why? Because carbohydrates break down into sugar very quickly. So while you wouldn’t offer your child a daily mid-afternoon snack of sodas and chocolate bars, those muffins, doughnuts, chips, and bagels should be on the “special treat” list as well.

Dental-healthy snacks

Luckily, we are left with many healthy and convenient choices when your child needs a nibble.

• Crunchy, crisp fresh fruits and vegetables provide vitamins as well as a gentle scrubbing action to help clean teeth. They are also rich in water, which helps us produce the saliva that naturally washes away food particles and bacteria.
• Low-fat yogurts and cheeses provide essential calcium for strong teeth and the vitamin D that helps us absorb calcium.
• Whole grain breads, cereals, and crackers are healthier than products made only with white flour because they retain valuable vitamins and minerals that have been removed from refined grains.
• Lean meats, peas, legumes, and eggs provide protein that helps build connective tissue and maintain tooth structure.
• Water helps stimulate saliva production and provides cavity-fighting fluoride. Win/win!

You are constantly looking for ways to make your children’s lives better. Mix and match any of these foods for a snack that’s not only good for their teeth, but rich in the proteins, vitamins, and minerals needed to keep them active and growing throughout their school years. If you have questions about your child’s dietary needs, feel free to ask Dr. Wendy Tang and Dr. Amy Bellamy at our Surrey, BC office.
