According to the Centers for Disease Control and Prevention (CDC), community water fluoridation has been a safe and healthy way to prevent tooth decay effectively for over 65 years now. In fact, the CDC has recognized water fluoridation as one of the 10 great public health achievements of the 20th century.

It all began back in the 1930's when it was discovered that fluoride had oral health benefits. However, community water fluoridation did not begin until January 25, 1945, when Grand Rapids, Michigan became the first city to add fluoride to its municipal water system. Before it was officially rolled out in other cities, Grand Rapids was compared to other cities or “controlled groups” that had not added fluoride to their water so that scientific research could assess the relationship between tooth decay and fluoride. Well, you can guess the results — it was proven that fluoride helped reduce tooth decay when added to ordinary tap water. On November 29, 1951, the National Academy of Sciences’ National Research Council (NRC) declared water fluoridation safe, effective, and beneficial based upon the results of their findings and the fact that there was a dramatic decline in tooth decay in the children of Grand Rapids.

Ever since, fluoride has continued to play a critical role as a simple, safe, effective way to provide improved oral health by helping reduce tooth decay in the United States. This reality is still being demonstrated with each new generation benefiting from better oral health than the previous generation.

As for identifying when the time is right to introduce fluoride to your children's oral health program, ask us. Most children get the right amount of fluoride to help prevent cavities if they drink water that contains fluoride. And if by chance you live in an area where your tap water is not fluoridated, brush your children's teeth with no more than a pea-sized amount of fluoride toothpaste twice a day and ask your dentist about fluoride supplements and treatment.

Can chewing gum prevent cavities? Yes! It can if the gum is sweetened with xylitol.

What is xylitol?
Xylitol is a type of “sugar alcohol,” similar to sorbitol and mannitol, sugar replacements that are used in many low calorie foods. Xylitol occurs naturally in many fruits and vegetables and is obtained from the bark of birch trees, coconut shells and cottonseed hulls. It looks and tastes like sugar and is a diabetic-safe, low-calorie carbohydrate.

How does xylitol stop cavity formation?
Decay starts when certain bacteria break down sucrose (regular table sugar) and produce acids that dissolve the minerals in the enamel, the outer protective layer of your teeth. When the decay-causing bacteria try to consume xylitol, they are unable to break it down, and instead they begin to starve.

A normal mouth contains a large population of bacteria, and it is better for your teeth to have more “good” bacteria of the kind that do not cause cavities. Xylitol also stops your saliva from becoming acidic, so your mouth becomes a better environment for the “good” bacteria.

Chewing xylitol gum also increases your flow of saliva. Saliva contains calcium and fluoride and helps give these minerals back to your teeth (re-mineralization), undoing some of the effects of the cavity-causing bacteria. This makes chewing xylitol gum a particularly good solution for people who suffer from dry mouth.

How much xylitol do you need to prevent cavities?
We recommend that you chew or suck on two pieces of xylitol gum or two pieces of xylitol candy for five minutes following meals or snacks, four times daily — if you are at moderate to extreme risk for cavities. The target dose of xylitol is 6 to 10 grams (one or two teaspoons) spread throughout the day. Prolonged gum chewing is not advised, so most xylitol-sweetened products contain flavor that only lasts a short time to discourage excessive chewing. The only side effect of too much xylitol ingestion is that it may have a mild laxative effect.

I don't like chewing gum. Is there another way to get xylitol?
People who don't like to chew gum have the option of using xylitol in mints, candies, mouthwash, toothpaste, or mouth sprays. For these individuals, a minimum dose is 5 to 6 grams (one teaspoon) three times per day.

So now you can add xylitol to the list of ways to fight cavities: daily brushing and flossing, and regular professional cleanings — and chewing xylitol gum.

Your teeth were designed to last you a lifetime, so you should do everything you can to protect them. This includes guarding them against dental erosion. However, many people may not know for sure what dental erosion is, much less how or why they need to guard against it.

Dental or tooth erosion is the irreversible loss of tooth enamel from chemical attack by acids. Eating or sucking acidic foods such as lemons is a good example. But most people are shocked to discover that it can also be caused by their favorite sodas (carbonated beverages), natural fruit juices, energy and sports drinks — especially with excessive consumption. It takes the saliva, nature's protection, at least 30 to 60 minutes to neutralize the effects of acid, so only one acidic drink an hour causes your teeth to be continually bathed in acid. And this is an important fact to know, because if your mouth is acidic all the time, this will promote tooth decay.

Will brushing help out with prevention?

When it comes to dental erosion, brushing immediately after acid consumption can actually make it worse by accelerating the erosion process. This is because the acids in these drinks (and some foods) actually dissolves tooth enamel and softens the tooth surface. These newly softened surfaces can literally be brushed away if you brush before your saliva has a chance to try to reverse the process. If done often, you could even brush away your enamel! For this reason, you should wait at least 30 to 60 minutes before you brush your teeth after consuming any of these products.

So what can you do to prevent dental erosion?

One important step that you (and your family) can do to help prevent dental erosion is to limit the amount of these beverages you drink. Instead, try drinking calcium-rich milk or water and saving your favorite acidic beverage for a special treat that you consume preferably with a meal. Try reducing the number of these drinks you consume over a period of time. If you must drink an acidic beverage avoid swishing it in the mouth and use a straw to reduce the contact between the acid and your teeth.

Just remember that once your dental enamel has eroded, it is gone forever. So you should follow these simple tips now to protect your smile and future.

Given the fact that baby-boomers are now reaching the age of retirement, understanding senior healthcare is becoming a top priority to many people. Discover your level of expertise in the area of oral health by taking the following true/false test.

True or False Self Assessment

1. All people eventually lose their teeth as they age.
2. Yellow teeth are a sign of gum disease.
3. If you have dentures, you no longer need regular dental check-ups.
4. Periodontal (gum) disease is a big problem that affects 3 out of 4 adults.
5. Electric toothbrushes can be a great option for seniors with arthritis or other debilitating conditions.

Answers

1. False: Your teeth are meant to last your lifetime.
2. False: Yellow teeth typically denote stained teeth from diet, medication, smoking, or growing older. And while they may not appear attractive, older, yellow teeth can in fact be healthy and free of gum disease. However, if your yellow teeth bother you, ask us if teeth whitening could be right for freshening up your smile while making you appear younger.
3. False: For those individuals who wear complete upper and lower dentures, you will always need routine dental exams, typically once a year so that you can be screened for cancer, as well as other oral conditions (i.e. candadiasis), to ensure the you obtain and maintain optimal oral health.
4. True: 75% of all adults over the age of 35 will experience some form of periodontal disease, a condition in which the gums become inflamed and infected. If left untreated, gum disease causes the bone that supports the teeth to deteriorate until the teeth are loosened and/or eventually lost (either they fall out on their own or must be removed). On a positive note, you can prevent gum disease by having good oral hygiene that includes flossing daily and brushing at least twice a day with a proper technique and fluoride toothpaste.
5. True: Under normal conditions, what matters most is not so much the type of toothbrush used (manual, electric or battery powered toothbrush), but rather how you use it. However, if you are unable to use a manual toothbrush effectively for proper brushing, then a power toothbrush may be able to facilitate proper cleaning more easily.
