Is this a trick question? After all, you and your family probably already know quite a lot about cavities:

• It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
• Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
• These acids gradually weaken teeth by dissolving minerals that help make up our enamel (a process called demineralization).
• Over time, a hole, or cavity, develops in the tooth surface.
• Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Dr. Guijon might discover an unexpected cavity at a regularly scheduled dental exam at our Huntington Beach, CA office, but there are also some symptoms that should have you calling for an appointment. A cavity can cause sensitivity when eating something hot or cold, or it can be painful, or you might even notice visible discoloration or damage to the tooth surface.

So, if your child has any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids. Acidic foods are one of the leading causes of tooth erosion.

And while we expect damage from a lifetime of acidic foods and beverages to catch up with us as we age, the fact is that erosion is becoming a problem even for young children. How is this possible? Let’s look at some food chemistry.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, fruit juices, flavored drinks, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

So, when might you suspect enamel erosion? Your child might be sensitive to hot or cold foods, or feel pain, or even have noticeable enamel loss or pitting. Even though these symptoms may not have been caused by plaque and bacteria, acidic erosion from our diets leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

• Serve acidic foods sparingly, or as part of a meal. This helps our saliva pH stay in the neutral zone.
• Balance acidic foods with low-acid choices to neutralize acids and restore a normal pH balance. For example, mix those acidic berries with a banana.
• Use a straw! These are not only fun, but this simple solution keeps erosive drinks from bathing young teeth in acids.
• Encourage your child to drink water instead of an acidic beverage, or drink it afterward to rinse acids away. The pH of pure water? A perfect, neutral 7. And by using tap water instead of bottled water, you’ll be providing fluoride, which helps strengthen enamel.
• What about brushing right after eating or drinking something acidic? Ask Dr. Guijon if your child should rush for the brush. We may recommend waiting 30 minutes or so after an acidic treat to give the teeth time to remineralize. Otherwise, brushing might cause more wear and tear on enamel.
• Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing these medical needs.

Be proactive. Ask your Dr. Guijon about healthy drinks and snacks for healthy teeth. Make sure to keep on top of brushing and flossing, and stick with fluoride toothpastes. And visit our Huntington Beach, CA office regularly for exams and cleanings.

There’s really no trick to it—preventing enamel erosion helps keep your child’s teeth structurally strong and cavity-free for a lifetime of beautiful and healthy adult smiles.

As adults, we often wish our teeth could be as white as they were when we were small children. Baby teeth have thinner and whiter enamel than adult teeth, and those brilliant smiles are a result! But occasionally, you may be surprised to discover some staining or discoloration on those lovely first teeth. You might be tempted to apply a whitening product to your child’s teeth, but, please—read on!

Causes of Staining

• Improper Brushing—Often, a loss of tooth whiteness means that plaque has built up on the tooth surface. Careful brushing is needed to remove bacteria and plaque, and if your child isn’t brushing at least twice a day for two minutes, discoloration can be the result.
• Medications—When given in liquid form, or when added to formula or food, iron supplements can cause dark grey staining on the teeth. Medications taken by a mother while pregnant or breast feeding, such as tetracycline, can also lead to discoloration.
• Injury—If a tooth suffers a serious injury, the tooth can darken because of changes inside the enamel.
• Health conditions—Certain health problems can cause tooth discoloration, or sometimes children are born with weaker enamel that is more likely to stain.

If you have noticed any staining on your child’s primary teeth, call our Huntington Beach, CA office. Simple stains can often be removed with better brushing techniques, and we can clean other surface stains in the office. Staining caused by an injury or a health condition is something we can discuss in detail with you. We can even use some professional whitening methods if those are indicated.

Why not just buy a home whitening kit for your child? There are several important reasons to leave these products on the shelf while your child is young.

• Whitening kits are designed for adults. They have been tested for adult teeth in adult trials. Check the box for age appropriate use. Most products are not recommended for pre-teen children.
• Remember that thinner enamel we mentioned earlier? Add to that the delicate skin of young children, and it’s sensible to be cautious about using a bleaching agent that can cause mouth and tooth sensitivity even in adults.
• There is no body of evidence available as to the short and long term effects of using these products on children.

If you are concerned about the brightness of your child’s smile, please talk to Dr. Guijon. We can recommend better ways to brush at home, clean your child’s teeth in the office, or suggest professional methods of whitening if there are physical or psychological reasons that it would be valuable. But while your child is young, those off-the-shelf whitening products can wait a few more years.

Sometimes the reason for a poor night’s sleep is obvious. Maybe your child watched a scary movie. Or loaded up on sugar before bed. Or can’t get to sleep after a night of computer screens or video games. Not much we can do about these problems.

Sometimes, though, the cause of your child’s sleep difficulties is dental in origin, and that is something Dr. Guijon can help with.

Teeth grinding, or bruxism, is a very common childhood dental problem. While children with this condition sleep, their jaws clench and their teeth grind against each other throughout the night. When to suspect children might suffer from bruxism? When they experience:

• Frequent headaches or facial pain
• Waking with a sore jaw, or popping or clicking jaw sounds through the day
• Teeth which are chipped, cracked, flattened, worn down, or sensitive
• Waking up tired, because grinding affects the quality of sleep
• Siblings who complain about nocturnal grinding noises, which affect the quality of their

Pain and fatigue are unpleasant enough, but there are additional serious consequences for those who suffer from bruxism. Our jaws are extremely powerful, and clenching and grinding can put hundreds of pounds on pressure on teeth and jaws over a few hours of sleep.

These forces can lead to damaged teeth and dental work, and problems with the temporomandibular joint, or TMJ, the complex hinge that allows our jaws to move up and down, back and forth, and side to side.

Clearly, prevention is clearly a much better option for a healthy smile. And one of the simplest and most effective treatments for preventing the damage caused by bruxism is a night guard.

Night guards fit over the affected teeth to prevent them from touching directly, saving tooth and enamel from injury and wear. Not only do night guards prevent contact, they spread the biting forces of the jaw over the surface of the guard to greatly reduce their impact. And because they also stop the jaw muscles from clenching tightly, there’s no excess stress placed on the temporomandibular joint.

For all these reasons, a night guard is pretty much a slam dunk for adults who grind their teeth. But for children, it’s not necessarily an automatic decision. Why?

• If tooth grinding is mild and appears to be limited to baby teeth, children often outgrow the condition. Your dentist can let you know if you need to do more than monitor the situation.
• Sometimes it seems like your child’s smile changes from day to day. Between losing baby teeth and erupting adult teeth, this beautiful smile is a work in progress. A fitted night guard might not be a perfect fit while your child’s teeth are still coming in and shifting position.
• Finally, jaw and facial pain can also be caused by problems with your child’s bite or misaligned teeth, and that might mean that an orthodontic consultation is in order.

But if you suspect your child is suffering the effects of night time grinding and clenching, give our Huntington Beach, CA office a call. A thorough examination will provide you with the best diagnosis and solutions for helping your child retain a healthy smile and regain a healthy night’s sleep.

And if a night guard is recommended, a dental professional is the best person to see for the most effective night guard.

While over-the-counter products are available, a custom night guard is designed to fit your child’s individual teeth and mouth perfectly. Impressions or 3D scans are taken in the office, and a guard is fabricated with the precise shape, strength, and thickness needed to protect young teeth. And, as a bonus, custom night guards offer the most comfortable fit for the most comfortable night’s sleep.

Scary movies, a late night sugar rush, mesmerizing video screens—not much we can do about those! But if your child is suffering lost sleep and painful mornings because of tooth grinding, give us a call. A night guard just might be the key to sweet dreams.

There’s nothing like the simple seasonal pleasures. What’s more enjoyable than a cup of hot apple cider on a blustery winter day, or a tall glass of ice water in the middle of a summer heatwave? Until, that is, tooth sensitivity makes that hot or cold treat no treat at all. If untimely tooth sensitivity is causing you problems, there are solutions we can offer!

Improving Brushing Technique

Careful brushing is a wonderful habit to get into, but sometimes there can be too much of a good thing. Over-energetic brushing can actually damage our enamel. And underneath that enamel is dentin, a more porous substance which allows heat and cold to reach the more sensitive inner tooth.

But, please, don’t give up on brushing! Switching to a soft-bristled or electric toothbrush and a toothpaste designed for sensitive teeth can make a world of difference. Dr. Guijon can recommend the most effective and safest way to brush, as well as suggest toothpastes designed to fight tooth sensitivity. Until you recover, now is the time to avoid acidic and sugary foods and drinks (which can also bother sensitive teeth) and home tooth-whitening products as well.

Preventing Gum Disease

When gum disease progresses, the gums can begin to pull away from the teeth. This recession exposes part of the root area, which is much more sensitive to heat and cold.  Regular checkups and cleanings can keep gum disease from developing. Gum disease that is already present can be treated, and we can discuss whether more intensive care, such as a gum graft, is advisable to protect the root area.

Treating Injuries to the Tooth

If you have a cavity, a fracture, or another injury to the tooth or nerve, sensitivity is a good sign that you should call us right away. And, sensitivity is a symptom that can disappear when we restore the compromised tooth, whether it requires a new or replacement filling, a crown, or a root canal. If your teeth are more sensitive as a result of tooth grinding or other orthodontic problems, we can identify those issues as well.

No matter the reason for your tooth sensitivity, we want to work with you to find out the cause of the problem and to find a solution for it. Call our Huntington Beach, CA office if you notice any unpleasant or painful reactions to temperature, foods or even wind and air. Whether it’s advice on correcting your brushing style or treating tooth and gum conditions, we are here to help you.
