Let’s talk about the science of our teeth for a moment. Our enamel has a very high mineral content, making it extremely strong.  In fact, enamel just happens to be the hardest substance in our bodies.  But, unfortunately, it is not indestructible! Certain foods we eat can actually damage the surface of our teeth. Some simple and entertaining experiments can show children how our teeth can be affected by things we eat and drink, and how we can help protect them.

If you have a science-minded student at home, there are many activities you can do together, using educational websites, common household products and lots and lots of eggs. (Why eggs? Eggshells are a great substitute for teeth in these experiments. Not only are they various shades of white--like our own teeth, they are also calcium-rich—like our own teeth.) You can find any number of experiments using uncooked eggs, hardboiled eggs, whole shells with the contents blown out, or eggshells alone, so you can find just the right activity for whichever egg treatment works best for you.

Examine Enamel Erosion

One of the ways we protect our teeth is with healthy eating. The bacteria in plaque use the sugars and starches in our foods to produce acids. These acids are the substances that break down the minerals in our enamel and leave the enamel weaker. Weaker enamel is more easily attacked by bacteria and acids, which leads to cavities.

With eggs or eggshells and some carefully selected food products, you can see just how acidity affects teeth. Different websites suggest a variety of acidic liquids to dunk your eggs in, such as vinegar, soda, or citrus juices, so it’s easy to find an experiment that works with your pantry. Always use a plain water sample when you submerge eggs or shells to act as a control to measure differences against. How do the egg shells soaked in acidic liquids differ from those in plain water? It’s also fun to add simple sugar water as a test liquid to see what happens. Is it sugar or acid that causes more damage? And why might that be?

The Fluoride Fix

Fluoride is well known as a mineral that protects the structure of our teeth and helps prevent cavities. And there are actually experiments out there to test the protection fluoride provides using your egg stand-ins.

In some experiments, a hardboiled egg is coated with fluoride toothpaste or rinse for a specific amount of time and then dunked into vinegar. An untreated egg also gets a vinegar bath. You are asked to observe what is happening to each egg as it sits in its vinegar bath—are there bubbles on one egg and not the other? What do the bubbles mean? Other experiments require longer exposure to fluoride and then to vinegar—what happens to the shells of the treated and untreated eggs? What could this mean for our teeth?

Staining Studies

Our diet can do more than help create cavities. Enamel is very strong, but it is not stain-proof! Dark colored foods and drinks can make our teeth appear darker or more yellow. (And teeth that have suffered enamel erosion can pick up stains more easily.) How does food affect the brightness of our smiles?

If this question interests you, find experiments that use favorite beverages as a soak for your eggs. Choose liquids with a range of color, such as coffee, soda, and apple juice. Or choose an experiment that uses different varieties of soft drinks. Will foods the same color cause the same amount of discoloration in your egg volunteers? Do you want shorter or longer soaks in each liquid? Do you want to make use of a recycled toothbrush to see if brushing that discolored shell makes a difference? With toothpaste or without?

Even though these activities are designed for older children, they still require adult supervision. You can find detailed instructions for any of these experiments at many science and educational sites online. With some household supplies, plenty of extra cups, and a quantity of eggs, you and your child can demonstrate some of the basic effects our food choices have on the health and appearance of our teeth. It’s a wonderful way to promote healthy eating and brushing habits, scientific curiosity, and shared experiences!

You have a lot more freedom as a teenager than you did as a young child. You also have a lot more responsibilities, and one of your jobs is to take care of your teeth. Develop and maintain good dental habits now so you can have great dental health for life!

Tooth Decay

As a teenager, you risk tooth decay, or dental cavities, if you are not careful. In fact, 59% of adolescents aged 12 to 19 have at least one cavity, according to the National Institute of Dental and Craniofacial Research. Dr Karina Gregg and our staff recommend keeping your teeth strong and healthy by brushing at least twice a day and flossing every day.

If you suspect that you have tooth decay, do not be embarrassed. Instead, ask your parents to bring you to San Elijo Dental to get it looked at. When you do not treat your dental cavities, they can turn into more serious problems. A severely damaged tooth may need to be treated with a root canal or even an extraction.

You can take easy steps to prevent tooth decay when you are at school or hanging out with your friends. Carry a bottle of water around with you so you can take a sip after you eat any kind of food. Choose water or milk instead of soda or sports drinks, and if you chew gum, select a sugar-free flavor.

Other Oral Health Concerns

You can probably think of many reasons why you should not smoke or use tobacco. Your oral health is another one. Tobacco gives you bad breath and stains your teeth yellow. It also increases your risk for gum disease and cancer of the mouth. Smoking even slows the speed of healing after you have dental procedures done.

Here are a few more tips that can keep your mouth attractive and healthy during your teen years.

• Drink plenty of milk.
• Limit candies and sugary snacks.
• Wear a mouthguard if you play a contact sport.
• Visit San Elijo Dental twice a year.
• Reduce infections and avoid piercing your tongue and lips.

You only get one set of permanent teeth in your life, so get in the habit of taking care of them now!

Snoring occurs when the tissues in the throat relax enough to block part of our airways, or physical conditions such as enlarged tonsils or a deviated septum prevent air from flowing freely. This obstruction causes the tissues around the airway to vibrate, producing that familiar, unpleasant sound. But sometimes, loud, constant snoring is a sign of a condition called Obstructive Sleep Apnea (OSA). With OSA, the sleeper actually stops breathing for a few seconds at a time, or, in some cases, even longer. The body wakes to breathe again properly, so we move from the deep sleep we need to keep ourselves healthy mentally and physically to a lighter state of sleep or wakefulness—and this disruption of the sleep cycle can happen dozens of times an hour.

The potential problems caused by sleep apnea are many. You could suffer from daily morning headaches, sore throats, and dry mouth (which can lead to tooth and gum problems). You might find yourself moody, depressed or forgetful. Irritability and loss of libido are common consequences of sleep apnea. Any or all of these problems can make getting through each day a struggle.

Even worse, sleep apnea can lead to very dangerous situations. You could fall asleep while working, watching your children, or even driving. Sleep apnea has been linked to very serious conditions such as high blood pressure, heart disease, and stroke. And for those who suffer from this disorder, general anesthesia or pain medication can lead to severe or even fatal consequences.

You should be examined for sleep apnea if you or a loved one notice any of the following symptoms:

• Snoring loudly enough to disturb your sleep or the sleep of others
• Waking up gasping for air
• Pauses between normal breathing during sleep
• Continual drowsiness during the day
• Waking up with headaches, sore throats or dry mouth regularly
• Personality changes

If you are diagnosed with sleep apnea, talk to Dr Karina Gregg at our San Marcos, CA office. We can point you in the right direction for treatment, including the possibility of crafting an orthodontic oral appliance to maintain open airways as you sleep. But whatever treatment you and your doctors decide on, the important part is following through. Don’t let an annoying situation become a dangerous, and even life-threatening, one.

As a parent, you want the best for your children, and that includes doing their best in school. You can support them by taking an interest in their activities, being enthusiastic about attendance, and helping them with homework. There may also be one more way you can help your children succeed at school. Surprisingly, research suggests that children with better oral health are likely to do better in school.

What the Research Says

One study in North Carolina looked at risk factors for poor school performance among school-aged children. As expected, the study found poor school performance linked to low socioeconomic status, low levels of parental education, and poor overall health. However, it also found a strong link between poor oral health and poor school performance, with children classified as having poor oral health 40 percent more likely struggle in school.

These findings are generalizable to the rest of the country. For example, attendance is an important factor in academic achievement, but dental conditions are responsible for a loss 51 million school hours among schoolchildren each year. Dental pain and infection are linked to poorer performance.

School-Based Programs to Promote Oral Health

In light of the apparent benefits of good oral health for school performance, some schools are taking steps to promote better oral care and health. In Maine, for instance, schools in need can apply for grants through School Oral Health Program (SOHP). The SOHP consists of four components:

1. Oral health education for all children to support healthy behaviors
2. A weekly fluoride mouth rinse to strengthen teeth
3. Dental screenings to identify children who may need dental care
4. Dental sealants, or plastic coatings, on back teeth to guard against decay

The State of Maine also supports an “Annual Sugar Out Day” to raise awareness of the effects of sugar on dental health and to help students choose low-sugar alternatives.

Oral Health Habits to Adopt

You can help your child improve oral health and do better in school by encouraging good oral hygiene. This includes brushing at least twice a day with a fluoride-containing toothpaste, and reminding your child to drink water after eating. Also, regular trips to our San Marcos, CA office can help prevent serious tooth problems.
