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 Tavarez Orthodontics. We look forward to seeing you soon!

This may come as a surprise, but brushing your teeth right after a meal can be one of the worst things you can do for your healthy teeth. A toothbrush can be considered an assault weapon against your smile if used immediately after eating certain foods.

Enamel is like the tooth’s shield. It is a hard mineral exterior on each of your teeth. In reality, enamel is the hardest part of the human body—even stronger than bone! I like to regard it as a “super-structure.” But every superhero has a weakness, and enamel’s kryptonite is acid.

A healthy tooth lives in a mouth that has a proper pH balance. When that balance tips from alkaline to acidic, a harmful process called demineralization begins. Demineralization occurs when acids attack and soften the tooth surface. Pores and fissures form and harmful bacteria move in.

With each bite of food or drink, our mouth pH fluctuates. Highly acidic foods tip the balance of your mouth from a healthy alkaline to a dangerous acid. Here are some examples of those sources of acid: citrus fruits, soda, and sugary foods. There are certainly many others, but these are the most common.

So how does brushing your teeth immediately after a meal make this process even worse?

After eating highly acidic foods, your teeth are susceptible to damage. When you brush your teeth in this weakened state you are actually damaging your enamel. The abrasive bristles of the brush wear away the protective surface of the teeth. You should avoid brushing for at least an hour, or take other, simple preventive measures immediately following a meal.

First, rinse with or drink clear water. Then chew some sugarless gum. Both of these practices will produce saliva, restore a healthy pH level in your mouth, and coat your teeth with nourishing minerals. Out of all the sugarless gums available, the best of the best are those that list xylitol as the first ingredient. Another option is to consume cheese, milk, or another non-acidic food or drink to conclude your meal.

After you have given your mouth time to return to a healthy pH, feel free to brush your teeth. Just keep in mind that any time you eat acidic foods, you weaken your teeth. Make sure not to worsen the problem by brushing immediately after dining and damaging your teeth even more. Questions? Call us at Tavarez Orthodontics.

It's a habit many people have and not only can it be annoying to the people around you, it can be detrimental to your dental health. Chewing ice is so common that it even has its own name, pagophagia. We're not talking about a slushy or shaved ice (although those artificially sugary treats should be avoided too!) but more like the hunks of ice rattling around in the bottom of your glass.

Ice chewing can be a sign of emotional problems like stress or obsessive-compulsive disorder, but it can also be a marker for iron deficiency anemia and other physical problems. Then again, some people just like to have something to chew on. For whatever reason you find yourself chewing on it, it's a habit you need to break.

Chewing on ice can cause:

• Chipped and cracked teeth
• Damaged enamel
• Sore jaw muscles
• Damage to dental work such as crowns, fillings, or other appliances

If chewing on ice is becoming a problem in your life, don’t hesitate to speak with Dr. Kathleen Tavarez about it. But if you find yourself still wanting to chew on something, here are a few alternatives to ice:

• Baby carrots
• Celery sticks
• Sugar-free (xylitol) gum

We know you need to chill sometimes, but chomping down your entire glass of ice is not the way to do it. If you have any other questions on the topic, feel free to talk with a member of our Menlo Park or San Carlos, CA team. It may be beneficial in solving the issue and helping to remediate any damage to your teeth.

Do you ever find yourself gnawing at your nails? Nail-biting is a very common and difficult to break habit which usually has its beginnings in childhood. It can leave your fingers and nail beds red and swollen. But if you think that your nails are the only ones getting roughed up by nail-biting you'd be mistaken—so are your teeth!

According to a study by the Academy of General Dentistry, those who bite their nails, clench their teeth, or chew on pencils are at much higher risk to develop bruxism (unintentional grinding of the teeth). Bruxism can lead to tooth sensitivity, tooth loss, receding gums, headaches, and general facial pain.

Those are some nasty sounding side effects from chewing on your nails. Most nail-biting is a sign of stress or anxiety and its something you should deal with. So what steps can you take if you have a nail-biting habit?

There are several things you can do to ease up on nail-biting:

• Trim your nails shorter and/or get regular manicures – Trimming your nails shorter is an effective remedy. In so doing, they'll be less tempting and more difficult to bite on. If you also get regular manicures, you’ll be less likely to ruin the investment you’ve made in your hands and fingernails!
• Find a different kind of stress reduction – Try meditation, deep breathing, practicing qigong or yoga, or doing something that will keep your hands occupied like squeezing a stress ball or playing with a yo-yo.
• Wear a bitter-tasting nail polish – When your nails taste awful, you won't bite them! Clear or colored, it doesn't matter. This is also a helpful technique for helping children get over the habit.
• Figure out what triggers your nail-biting – Sometimes it's triggered by stress or anxiety and other times it can be a physical stressor, like having hang nails. Knowing what situations cause you to bite your nails will help you to avoid them and break the habit.
• Wear gloves or bandages on your fingers – If you've tried the steps above and they aren't working, this technique can prove effective since your fingernails won't be accessible to bite.

If you're still having trouble with nail-biting after trying these self-help steps, it's best to consult your doctor, dermatologist, or Dr. Kathleen Tavarez. For some, it may also be the sign of a deeper psychological or emotional problem.

Whatever the cause, nail-biting is a habit you need to break for your physical and emotional well-being. If you have any questions about the effects it can have on your oral health, please don't hesitate to ask Dr. Kathleen Tavarez during your next visit to our Menlo Park or San Carlos, CA office.
