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!

Don’t forget to let Dr. Guijon know how your experiments turned out the next time you visit our Huntington Beach, CA office!

You’ve always taken care of your child’s smile. You make sure thorough brushing and flossing take place twice a day. You serve foods high in vitamins and minerals and low in sugar. You make and keep regular dental appointments at our Huntington Beach, CA office. But even with the best dental routines, sometimes conditions can occur that will require additional professional care.

One of these conditions can affect your child’s enamel while the tooth is still forming. When baby teeth or adult teeth appear, you might notice white, creamy yellow, or brown spots in otherwise healthy-looking enamel. These spots are softer and rougher than normal hard, smooth enamel. Because of their texture and color, such teeth are often referred to as “chalky teeth,” but this condition is actually known as enamel hypomineralization.

What is hypomineralization?

Enamel is the strongest substance in our bodies—stronger even than bones. Enamel is largely composed of minerals. If something disrupts the process of enamel development in baby or adult teeth, the result can be abnormally low mineral content in the enamel. This leaves teeth weaker and more likely to suffer decay and damage.

Premature birth, low birth weight, and other pre-natal factors have been suggested as risk factors for hypomineralization in primary teeth enamel. Permanent teeth can be vulnerable to this condition as well. Adult teeth are forming in young children well before they make an appearance. It’s been suggested that certain early childhood factors, such as recurring high fevers, some diseases, even specific antibiotics, can interrupt the formation of the enamel and lead to hypomineralization of adult teeth.

What are the results of enamel hypomineralization?

Children with this condition are much more likely to experience rapid tooth decay because of their weaker, more porous enamel, especially in the molars. Further, they tend not to respond as well to the numbing effects of local dental anesthetics, while their teeth tend to be more sensitive to pain. Cases can be mild, moderate, or severe. In severe cases, teeth might require crowns or possibly extractions, but even mild discoloration and other cosmetic problems can lead to self-consciousness in your child.

How can we help?

Catching this condition early is very important. If your child has had any medical conditions that might affect tooth development, let Dr. Guijon know even before that first tooth comes in. If you notice anything unusual about a new baby or adult tooth, give us a call. For primary or permanent teeth, the sooner we can begin treatment, the better the long-term outlook.

We might suggest fluoride applications or desensitizing treatments. We can apply sealants to reduce the risk of cavities, and use bonding to restore discolored or weak patches in the tooth. Both of these methods have greater success if the enamel near the affected area is in good condition, so early treatment is vital. If teeth require more protection, crowns are often the best choice. We will design a treatment program to suit your child’s individual needs now and for the future.

How can you help?

Dental hygiene is important for every child, but especially for a child with weak and porous enamel. Because children with hypomineralized enamel develop cavities more quickly that those with strong enamel, it is very important to watch your child’s diet and keep to a regular, careful, and thorough routine of brushing and flossing at home. Be attentive to any sensitivity problems, and be sure to follow any suggestions we might have for strengthening enamel.

Remember, early diagnosis and treatment is always best! If at any time you notice chalky patches, or have any other concerns about the appearance of your child’s teeth, if they seem to be causing your child pain or are unusually sensitive, call Dr. Guijon immediately. We want to work with you to treat any current problems and to prevent new ones.

When we don’t keep up with our dental hygiene, plaque buildup can result in three kinds of cavities. Pit and fissure cavities are found on the tops of molars, where food particles get stuck in the irregular surfaces. Smooth surface cavities are located on the smooth sides of teeth.

Wait. Top, all around the sides—what’s left for plaque to attack?

Our roots. The roots of our teeth are generally protected by their concealed position in the jaw. Sitting securely in alveolar bone, held firmly in place by connective tissue, with gum tissue snugly surrounding them, roots are generally not cavity prone.

But these cozy conditions can change. Due to gum disease, abrasive habits, or simply the passage of time, gums can recede and expose root surfaces. And this exposure can lead to root cavities.

If you look at a complete tooth, it looks like enamel is covering the entire tooth surface. In fact, enamel, the strongest substance in the body, only covers the visible part of the tooth, called the crown. The roots are covered by a substance called cementum, which is softer than enamel. And if enamel can’t stop decay, cementum is even more vulnerable when it’s exposed to plaque, bacteria, and acidic foods.

How do we protect our roots from decay? Protecting our gums is the first line of defense.

• Gum Disease

Receding gums caused by periodontitis can be treated by Dr. Guijon. Deep cleaning procedures such as scaling and root planing can remove accumulated plaque and tartar, and help gum tissue reattach to teeth. For serious recession, gum grafts can replace lost tissue.

Early treatment can prevent recession. If you notice any signs of early gum disease, including bleeding, swelling, tenderness, or persistent bad breath, it’s time for a visit to our Huntington Beach, CA office.

• Gum Abrasion

It’s not just gum disease that can lead to gum recession. Some personal habits are hard on gums and teeth, and can leave roots exposed. If you bite your nails, grind your teeth, irritate your gums with oral piercings, you are at risk for gum recession. Talk to Dr. Guijon about preventing abrasive damage.

A surprising cause of receding gums? Over-vigorous brushing. Use a soft-bristled brush—and don’t use a heavy hand when brushing—to protect your delicate gum tissue.

• Aging

As we age, our gums recede. So it’s no wonder that older adults are especially at risk for root cavities. That’s why it’s very important to keep up with brushing (at least two minutes twice a day) and flossing (once a day, or more often if needed) to prevent the buildup of plaque and tartar.

And it’s more important than ever to schedule regular dental exams and cleanings. Dr. Guijon can help stop small problems from becoming major ones, and suggest brushing and flossing techniques, fluoride treatments, or other procedures to encourage gum and dental health.

If a cavity develops, no matter what kind, it should be treated as soon as possible. And time is especially important for a root cavity.

Because cementum is weaker than enamel, cavities can progress more quickly in roots. A cavity which has reached pulp tissue might require a root canal and a crown to restore tooth function. Serious decay could lead to extraction.

Don’t let root cavities undermine your dental health. If you notice any sign of gum disease or recession, it’s time for a visit to our Huntington Beach, CA office. After all, even though they go unnoticed, strong roots are the foundation of a healthy, attractive, life-long smile.

At Surf City Pediatric Dentistry, we know that as many as one in 88 children today have some form of autism, a complex brain disorder that affects a child's ability to communicate or form relationships, and makes a child appear distant, aloof, or detached from other people or surroundings. Autism varies widely in symptoms and severity, and some people have coexisting conditions such as intellectual disability or even epilepsy.

That is why Dr. Guijon and our team are specially trained to provide dental care to the entire special needs community, including autistic children. We know that a visit to the dentist with an autistic child can be difficult. In addition to the common fears associated with strangers, there are also unfamiliar sounds, sensations, bright lights, and tastes with which your child may not be comfortable. We work with parents to make sure visiting the dentist is not so traumatic for our autistic patients.

Dr. Guijon and our team also know that patients with autism may be more interested in equipment and instruments than in us. We show our patients every piece of equipment we are going to use in a way that they can understand. We also allow a patient to sit in a parent's lap in the open bay if he or she is not feeling at ease. We want your child to enjoy getting to know us and to be comfortable while under our care.

A pleasant, comfortable visit at our Huntington Beach, CA office builds trust and helps put your child at ease for future appointments. Before a visit, we ask parents or guardians to bring their child's favorite toy, comfort item, music, or other coping device their child requires. We have a caring and compassionate team and know how to help autistic children acclimate themselves to a dental environment. We may not get everything done at the first visit, but we are able to schedule several appointments so that your child can get used to our office, the dentist, instruments, and our staff.

Children, especially those afflicted with autism, are not born with a fear of the dentist, but they can fear the unknown. Our team at Surf City Pediatric Dentistry genuinely cares for our patients beyond their teeth, and are more than happy to discuss any concerns you may have, as well as answer questions about your child's ongoing dental treatment. Please give us a call to learn more or schedule an appointment with Dr. Guijon.
