“What is the strongest substance in the body?” If this question comes up on trivia night, be prepared to impress your team when you confidently answer, “Tooth enamel!”

Tooth enamel? The reason for this surprising answer lies in the biology of our teeth. Minerals make up well over 90% of our enamel, a much higher percentage than is found anywhere else in the body, including our bones. But unlike bone tissue, which can heal and regenerate, tooth enamel cannot. Even though it is extremely strong, enamel can be damaged by a process called demineralization.

Demineralization

Demineralization is a result of acids at work in our mouths. Acids actually break down the minerals in our enamel, making the enamel softer. Over time, bacteria attack deeper into the tooth, eventually leading to decay. Acidic foods like sodas, citrus, pickles, and coffee are obvious culprits in providing an acidic environment, but there are other problem foods as well. We all have bacteria in our mouths, which can be helpful or harmful. The bacteria in plaque use the sugars and starches we eat to produce even more acids.

This process is something that takes place very quickly. In fact, even brushing too soon after eating something acidic can damage the demineralized surface of a tooth. Waiting at least 20 to 30 minutes to brush gives our bodies a chance to restore the enamel surface in a process called remineralization.

Remineralization

Our bodies are actually designed to help protect our enamel, and the most important part of this process is saliva production. Saliva cleanses our teeth and reduces levels of acidity. And our saliva constantly washes important minerals over our teeth. Calcium and phosphate ions rebuild and strengthen molecules where demineralization has taken place. This process is called remineralization.

We have other ways to help the remineralization process along. Fluoride toothpastes and fluoridated water speed up the movement of mineral building blocks back to the surface of the tooth. Fluoride also strengthens our teeth so that they resist acids and demineralization better than teeth without fluoride, making them less vulnerable to cavities.

New products are available for home and professional use that are designed to increase remineralization—talk to Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying at our Hiawatha, IA office if you would like the latest recommendations.

Did you know that there are certain foods you can eat which help to clean your teeth? We call them "detergent foods." In dentistry we look at the impact of food in three ways: the kind of food, how often it is eaten, and when it is eaten. Detergent foods should be the last piece of food you consume during a meal for best results. Think of them as the closest you can get to brushing your teeth.

A healthy diet is important for oral health as well as overall health, but here are some particular foods that can help clean your teeth and mouth:

• Carrots
• Apples
• Celery sticks
• Popcorn
• Cucumbers
• Pears
• Lettuce
• Cheese

As you can see, detergent foods are usually foods that are firm and crisp. They act like scrubbers on and around your teeth and gums and bring your mouth's pH back to 7.0, which is optimal.

Which foods are the worst for your teeth?

Cookies, cakes, breads, chips, crackers, soft drinks, dried fruit, and candies (what many people’s diets are full of) provide carbohydrates (sugar) to the bacteria in your mouth causing an acidic environment and increasing the chance of cavities and decay. These foods are sticky and don't rinse easily from your mouth. Avoid letting these foods sit on your teeth after eating them.

It also depends on how often you consume these foods throughout the day. For example, if you drink soft drinks, it's best to have it all in one sitting instead of sipping it all throughout the day. Doing so causes the perfect environment in your mouth for bacteria to flourish and your saliva never gets the chance to neutralize its pH.

This is where detergent foods can come into play. When you're about to finish your meal, have an apple, celery stick, or carrot. It will act like a "natural toothbrush." Also, try to make these detergent foods the basis for snacks you have throughout the day.

Always remember, these foods are not a replacement for brushing and flossing. You still need good dental hygiene regardless of what you're eating!

Straighter teeth is something many people desire. A nice smile is one of the most attractive things about a person. However, wearing a mouth full of braces for two, three, or more years can be a major pain, both literally and figuratively.

Luckily, there is another option. Invisalign is an alternative to traditional braces. Learn more about the benefits Invisalign offers and why you should consider this exciting method of straightening teeth.

• When you have straight teeth, your mouth is healthier in general and there is less chance of tooth decay and gum disease. Invisalign makes it possible for more people to straighten their teeth.
• Invisalign is essentially invisible. You can straighten your teeth without unsightly metal in your mouth.
• The average cost is similar to that of traditional braces, which makes it affordable for many families.
• With Invisalign, the aligner trays are smooth and comfortable to wear. Traditional metal braces can be uncomfortable and cause irritation to the mouth.
• Invisalign is removable, so you do not have to wear the system during special occasions, or when you’re eating. With normal metal braces, you are stuck with them for the entire straightening process.
• Brushing and flossing are simple. Since the system is removable, you can brush and floss just like normal.

As you can see, Invisalign is an exciting option we provide at Blair Ridge Dental for those who want straighter teeth. If this is something that sounds interesting to you, talk to Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying and find out if it would work for your particular situation. Get started today, and before you know it you will be enjoying your straighter teeth.

Probably because, for many kids, molars do get more cavities. So let’s answer two better questions: Why do molars get more cavities? And, how can we help prevent them?

It’s the Pits. (And Fissures.)

The reason molars are so useful—and more likely to develop cavities—is because of their shape. Unlike our front teeth, which are used to bite through foods, molars are used to grind and chew. That’s why they are so much larger, with a flat surface on top. Well, not exactly flat.

When you look at a molar, you’ll notice that the top isn’t really smooth at all. It’s covered with little indentations known as pits and longer grooves called fissures. These irregular features both trap food particles and make it more difficult for bristles to clean them away. Cavities in molar surfaces are so common that they even have a specific name: “pit and fissure cavities.”

But molar biology does not mean tooth decay is inevitable! There are steps you can take to protect your children’s molars as they grow, while you’re providing them with dental strategies that will keep their adult molars healthy and cavity-free.

Preventing Pit and Fissure Cavities

• Don’t Just Brush—Brush Effectively

The first step in preventing any kind of cavity is brushing properly. Your child should be brushing at least two minutes, at least twice each day. And while the time we spend brushing is important, technique is also key.

When you’re showing your child how to brush, be sure that the tops of molars, upper and lower, get brushed thoroughly, with special emphasis on cleaning pits and fissures. Make sure the toothbrush is small enough to fit your child’s mouth comfortably and reach all the tooth surfaces. Replace worn-down brushes or electric toothbrush heads after three to four months when they no longer clean as effectively.

Your child will probably need adult supervision from toddler years through the early years of grade school to learn how to brush properly. This is time well spent, as your child learns cavity-preventing brushing techniques which will last a lifetime.

• Eat a Tooth-Healthy Diet

Plaque bacteria use the sugars in our food to make acids. These acids break down the mineral strength of tooth enamel and eventually lead to cavities. And because pits and fissures are great hiding places for bacteria and food particles (especially sticky ones), molars are even more at risk for cavities. Limiting sugary, sticky foods like sweet treats and simple carbs helps reduce that risk.

Acidic foods like flavored juices, sour candies, sodas, and power drinks also weaken enamel and can leave teeth more vulnerable to decay. Help your child avoid cavities by limiting acidic foods and drinks, making them part of a balanced meal, and/or rinsing with water after eating.

• Use Fluoride Toothpaste

Fluoride toothpaste not only reduces the risk of cavities, it also helps strengthen enamel that has been weakened by bacterial and dietary acids. Win-win!

• Ask About Sealants

Sealants are invisible, safe coatings which protect molars by preventing food and bacteria from getting trapped in their uneven surfaces. The top of the molar is first treated with an etching solution to allow the sealant to bond tightly to the tooth, a thin coat of sealant is painted on, and then it’s hardened under a curing light. That’s all there is to it.

Sealants are often recommended when children’s permanent molars first erupt, when they are especially at risk for cavities. Sealants can last from three to five years (or even longer), and studies have shown a dramatic reduction in cavities for patients who use sealants compared to patients with untreated teeth. Depending on your child’s individual needs, Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying might recommend a sealant for baby molars as well.

• Regular Exams and Cleanings

It might be hard for you to tell if your child’s molars have been affected by sticky plaque, or sugary foods, or acidic drinks, or inadequate brushing, or any other potential cavity-causers. It’s not a difficult job for Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying, though! Through regular checkups and cleanings at our Hiawatha, IA office, we will discover any conditions that might lead to cavities, and, if necessary, treat small cavities before they lead to more serious decay.

Statistically, childhood molars have a greater chance of developing cavities than incisors and canines. Help your child beat the odds by understanding why these teeth are at risk and by working with your dental team to give your child years of healthy teeth now and a future filled with beautiful smiles!
