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. Wendy Tang and Dr. Amy Bellamy might discover an unexpected cavity at a regularly scheduled dental exam at our Surrey, BC 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. Wendy Tang and Dr. Amy Bellamy 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. Wendy Tang and Dr. Amy Bellamy 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 Surrey, BC 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.

Your beautiful baby is finally asleep, bottle clutched in tiny hands, dreaming sweet dreams with a charming milky smile.

Unfortunately, this lovely fantasy might lead to a rude awakening. If your child goes to sleep every night with a bottle, the chance of childhood cavities greatly increases. In fact, there is even a name for it—baby bottle tooth decay.

How Can Bottles Lead to Tooth Decay?

Cavities are created when oral bacteria produce acids that erode enamel, the protective outer coating of the tooth. These bacteria love to feed on sugar. Baby formula and even breast milk contain carbohydrates in the form of sugars. And this is not a bad thing!

Carbohydrates are essential for babies (and adults as well) for growth and development. Lactose, the sugar found in breast milk, is a carb that is easy for your baby to digest and helps good bacteria in the digestive system grow. Formulas with cow’s milk also contain lactose, and even the other kinds of sugars found in formula provide your baby with necessary, easily digestible carbohydrates.

But when your child goes to sleep with a bottle, those healthy sugars aren’t all being digested. Liquid can pool in the mouth bathing those perfect new teeth with sugar all through the night. That’s why we don’t recommend letting your child go to sleep with a bottle of formula.

And if your older child’s bottle is filled with juice or other sugared drinks, the effects are potentially much more harmful. Eventually, sugar left in the mouth all night will lead to the development of cavities, and in severe cases, to infection and even tooth loss. The upper front teeth are most often affected, but other baby teeth can become decayed as well.

How Can You Help Prevent Baby Bottle Decay?

• Start early by gently wiping your baby’s gums and erupting teeth after each bottle or breast feeding with a clean, damp washcloth or gauze pad. (Even though breastfed babies have a reduced risk of early cavities, it’s still a good idea to clean their gums and teeth after feedings.)
• Once those little teeth have come in, use a baby-size toothbrush to gently clean them. Talk to us about toothpaste—when and how much is appropriate for your child.
• Babies generally require breastfeeding or formula at night to get the nutrition they need. It’s best if they finish their feeding before naps or bedtime so you have a chance to clean little mouths. If your toddler carries a bottle or sippy cup through the day, or insists on a bottle at night, talk to us or your pediatrician for ideas on how and when to substitute tooth-healthy options such as water.
• Limit unnecessary or unhealthy sugars. Never put sugar-heavy juices and sodas in your child’s bottle or cup, or sugar or honey on a pacifier.

Your Child’s Baby Teeth Are Important

Your child will start losing those baby teeth around the age of six, but primary teeth provide many irreplaceable benefits before they are, well, replaced. Using the teeth to bite and chew food helps form proper eating habits and develop jaw and facial muscles. Baby teeth help with speech development, and they serve as place holders to make sure the adult teeth erupt in the right spot. Losing baby teeth too early can interfere with all of these goals.

As soon as that first tooth makes its appearance, or by the age of one, bring your baby to our Surrey, BC office for a first checkup. Dr. Wendy Tang and Dr. Amy Bellamy and our team will not only make sure everything is going according to schedule, but we will check tiny teeth for enamel erosion and even cavities. Most important, we’ll suggest ways to prevent cavities and tooth decay with proactive dental care. We have many great ideas on making sure your little one’s teeth are healthy from bottle to baby teeth, preparing your child for a lifetime of beautiful, healthy smiles. And that’s a dream come true!

We probably all remember sitting through history lessons during our schooling years. Revolutionary war heroes, English royals, and pop-culture icons filled the pages of our textbooks. Although you may recall a detail or two about their historical significance, how much do you know about their teeth?

Picture England in the mid 1500s. People wore frilly clothes as they hustled along the street, and talked about the latest import from the Indies: sugar. Wealthy Brits did not hesitate to indulge their sweet tooth, and it was no different for the monarch, Queen Elizabeth I.

The queen was especially fond of sweets, but not so fond of the dentist. Her teeth rotted; they turned black and gave off a foul odor. Eventually, Elizabeth lost so many teeth that people found it difficult to understand her when she spoke.

Flash forward to the Revolutionary-era colonies in the 1770s and we encounter the famous dentures of George Washington. They were not made of wood, but rather a combination of ivory and human teeth, some of which were his own pulled teeth and some he purchased from slaves.

Washington did not practice proper dental hygiene throughout his life. He began to suffer dental problems as early as age 24, when he had his first tooth pulled. By the time he was inaugurated in as the first president in 1789, he had only one tooth remaining in his mouth, which was pulled in 1796.

Washington’s dentures were made too wide and never quite fit his mouth properly. He complained that they were painful to wear and caused his jaw to protrude visibly outward.

If you’ve heard of Doc Holliday, you know him as the gun-toting, mustached criminal that ran the Wild West in the late 1800s. You might be surprised to learn that John Henry “Doc” Holliday actually had a career as a dentist.

He graduated from dental school in 1872 and began to practice in Griffin, Georgia. Holliday was later diagnosed with tuberculosis and his violent coughing fits during exams drove patients away. Jobless, he packed his bags for Texas and spent the rest of his days running from town to town as a criminal.

The Beatles brought pop music and British culture to their fans, as well as … teeth? In the mid-1960s, John Lennon had a molar removed that he presented as a gift to his housekeeper, Dorothy. Dorothy’s daughter was a huge fan of the Beatles and he thought she might like to a keepsake. Her family held onto the tooth until 2011, when they auctioned it off to a Canadian dentist for $31,000.

These historical figures had very different experiences with their teeth, but it’s safe to say a bit of extra brushing and flossing could’ve saved them a lot of trouble. Whether you’re queen, president, or an average citizen, it’s up to you to practice good dental hygiene!

Ask a member of our team at our Surrey, BC office if you have any questions about how to keep your teeth in top shape!

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. Wendy Tang and Dr. Amy Bellamy 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 Surrey, BC 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.
