Learning to suck their thumbs is one of the first physical skills babies acquire. In fact, ultrasound images have revealed babies sucking their thumbs in the womb! Babies have a natural sucking reflex, and this activity is a normal way for your baby to soothe herself.

If your toddler still turns to her thumb for comfort, no need to worry. Most children give up this habit as they grow, and generally stop completely between the ages of two and four. But what of the child who doesn’t? Should you encourage your child to stop? And when?

When Thumb Sucking Becomes a Problem

After your child turns five, and certainly when her permanent teeth start to arrive, aggressive thumb sucking is something to watch for. This type of vigorous sucking, which puts pressure on the teeth and gums, can lead to a number of problems.

• Open Bite

Our bites are considered normal when the upper teeth slightly overlap the lower where they touch in the front of the mouth. But with aggressive thumb sucking, teeth are pushed out of alignment. Sometimes this results in a condition called “open bite,” where the upper and lower teeth don’t make contact at all. An open bite almost always requires orthodontic treatment.

• Jaw Problems

Your child’s palate and jaw are still growing. Aggressive thumb sucking can actually change the shape of the palate and jaw, and even affect facial structure. Again, orthodontic treatment can help, but prevention is always the better option!

• Speech Difficulties

Prolonged thumb sucking has been suggested as a risk factor for speech disorders such as lisping, the inability to pronounce certain letters, or tongue thrusting.

The consequences from aggressive thumb sucking can be prevented with early intervention. What to do if you are worried?

Talk to Us

First, let us reassure you that most children stop thumb sucking on their own, and with no negative dental effects at all. But if your child is still aggressively sucking her thumb once her permanent teeth have started erupting, or if we see changes in her baby teeth, let’s talk about solutions during an appointment at our Kingston, ON office. We can offer suggestions to help your child break the habit at home. There are also dental appliances available that can discourage thumb sucking if your child finds it especially hard to stop.

Work with your Child

• Be Positive

Positive reinforcement is always best. Praise her when she remembers not to suck her thumb. Make a chart with stickers to reward every thumb-free day. Pick out a favorite book to read or activity you can share.

• Identify Triggers

Children associate thumb sucking with comfort and security.  If your child turns to her thumb when she’s anxious, try to discover what is bothering her and how to reassure her. If she automatically sucks her thumb when she is bored, find an activity that will engage her. If she’s hungry, offer a healthy snack.

• Talk about It!

Depending on her age, it might help your child to understand why stopping this habit is important. We are happy to explain, in a positive, age-appropriate way, just how breaking the thumb sucking habit will help her teeth and her smile.

Again, most children leave thumb sucking behind naturally and easily. But if what is a comfort for your child has become a concern for you, please give us a call. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok will work with you and your child to prevent future orthodontic problems and begin her lifetime of beautiful smiles.

Your beaming smile makes a sunny day even brighter—and that sunny day can return the favor! How does the sun affect your dental health? Let’s shine some light on the subject.

You may have heard how important calcium is to your body. Over 99% of the calcium in our bodies is used to form teeth and bones, providing strength and structure to the hardest parts of the body. But that’s not the only task on the calcium to-do list. Calcium is also necessary for:

• muscles to work
• nerves to carry messages
• blood to deliver nutrients and oxygen
• the release of hormones

When we don’t get enough calcium in our diets, our bodies start to draw the calcium they need for these critical functions from our teeth and bones. Over time, a severe calcium deficiency can lead to teeth that are brittle, or more vulnerable to decay, or loose due to weakened bone density in the jaw.

We can get the calcium we need from a balanced diet. Dairy products are our most common source of calcium, and several servings of milk, cheese, or yogurt each day supply most of our needs. If dairy’s not on your menu, though, you can get calcium from other foods like broccoli, kale, collard greens, canned salmon, or sardines. Because calcium is so essential to our health, many foods are fortified with it, including fortified juices, bread, cereals—even tofu!

But there’s a snag here, and it’s a big one. We can’t really benefit from our careful consumption of calcium without the help of vitamin D. If calcium is the doorway to strong teeth and bones, vitamin D is the key that unlocks all of calcium’s benefits.

Without enough vitamin D, our bodies can’t absorb and make use of calcium. However, getting enough of this essential vitamin can be a problem. While we can get most of the vitamins we need from a balanced diet, there aren’t a lot of foods which are naturally rich in vitamin D.

So, how do we get this vital vitamin? The original option comes from nature.

• Sunlight

Vitamin D is called “the sunshine vitamin” because of the unique chemical reaction that creates it. When the ultraviolet B rays of the sun reach special cells in our skin, they convert cholesterol in these cells to a basic form of vitamin D. These vitamin molecules travel through the body, picking up hydrogen and oxygen molecules in the liver and kidneys to become active vitamin D.

Since sunlight exposure is easy, available, and free, it seems like a simple solution to getting the vitamin D we need.

But we’ve understandably moved away from the days of basking in the sun for hours at a time. Over-exposure to UV rays damages the skin, causing premature aging and, worse, a much greater risk of skin cancer. If you enjoy time in the sun, talk to your doctor about safe sun exposure, which can depend on the part of the country you live in, the time of year, and your individual skin type.

And, if you need to avoid sun exposure, there are other opportunities for getting the vitamin D you need.

• Diet

While there aren’t a lot of foods which are naturally rich in vitamin D, there are still a few options on the menu. Oily fish like salmon, tuna, and herring—and old-fashioned cod liver oil—are good sources of the vitamin. But most of us don’t live on a strict fish diet!

Instead, we can get the vitamin D we need from fortified foods. Vitamin D is commonly added to cow’s milk, soy milk, orange juice, and cereals to make sure the calcium in our diet is working effectively to keep our teeth and bones strong. Check out nutritional labels to discover whether your favorite grocery products contain vitamin D.

• Supplements

For hundreds of years, people who lived in climates and cities without a lot of sunshine suffered from the effects of vitamin D deficiency. Diseases like rickets, where the teeth and bones don’t form properly, were common in children. Adults who couldn’t absorb enough calcium suffered from weak teeth and bones.

Today, depending on age, allergies to sun or food products, dietary choices, and health conditions, some people are still at risk for vitamin D deficiency. If you’ve been diagnosed with this deficiency, your doctor might recommend a vitamin D supplement. (It’s important to take any supplement as directed, because taking too much vitamin D can be harmful, too.)

So, which form of vitamin D is best? Fortified foods? Supplements? Or is it that radiant original source—the sun? No need to worry. With any form of vitamin D, you’re getting the key you need to unlock the benefits of the calcium in your diet—benefits which make healthy teeth and bones possible.

If you have any concerns, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at our Kingston, ON office about whether you’re getting the vitamin D you need. Your sunny smile will thank you!

Chewing gum can be a sticky problem. We’re not talking about etiquette, or nutrition, or how to get rid of the darned stuff when you don’t have a trash container handy. No, we’re talking about gum and its effects on dental health. So, let’s take a moment to chew over the benefits and drawbacks of chewing gum.

• First, the Good News about Gum

One of the important benefits of chewing gum is increased saliva production. This might not sound especially appealing, but here’s an important fact: saliva is one of oral health’s unsung heroes.

Saliva helps wash away food particles which feed the bacteria in plaque. It helps neutralize acids in the mouth which can damage tooth enamel. The minerals in saliva actually help rebuild weak spots in our enamel.

And, since sugar-free gum has revolutionized the gum-chewing world, we don’t bathe our teeth in sugar while we chew. This is a major advantage, and it’s why sugar-free gums are the only products which are ADA approved. A possible downside? Some people who chew certain sugar-free gums (especially people who chew a lot of them) can experience digestive problems.

• What about Dental Work?

Yes, gum can be tricky for dentures, crowns, braces, and other dental work, especially with very sticky and chewy products. There are gums out there that claim to be safe for dental work, but finding the right gum can involve some trial and error that you might prefer to avoid. This is a good subject to discuss with Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok.

If you have a temporary crown protecting a tooth until your permanent crown is ready, avoid gum entirely until your restoration is complete. The pulling effect of sticky, chewy gum can make your temporary crown even more temporary than you were expecting! After your crown’s finished, talk to your dentist about chewing gum again.

• “Chews” Wisely

Chewing means jaw movement and pressure. Hours of chewing means hours of jaw movement and pressure. If your jaws ache after a gum marathon, maybe it’s time to cut back! But, if your jaws ache whenever you chew, that’s a sign that a visit to our Kingston, ON office is in order.

The temporomandibular joint (TMJ) is a kind of hinge which allows your mouth to open and close and move from side to side—in other words, to talk, eat, drink, yawn, make faces—all those things we do all day long. Recurring jaw pain can be a sign of TMJ (temporomandibular joint) disorder.

Bruxism, or tooth grinding, is another reason to leave gum off your shopping list. When you grind your teeth, you’re putting stress on your teeth and jaws which can lead to cracked and chipped teeth, headaches, and tooth and jaw pain. If you’re working on getting your bruxism under control, you’ll want to avoid chewing gum and other habits which cause jaw clenching.

You and your dentist are the people who know your oral health best. If you suffer from dry mouth and think chewing gum might help with saliva flow, or if you’re worried about your dental work being damaged by gum, or if you have jaw pain when you chew, or if you have any concerns about your oral health, visit Cataraqui Dental Centre for all the answers to your sticky questions.

Painful nails and cuticles, ruined manicures, reluctance to shake hands—there are so many good reasons to overcome the nail biting habit. But did you know that biting your nails is also bad for your dental health? Let’s look at a few more reasons to give our nails a break.

• Bacteria Bonanza

It’s a vicious—and unhealthy—circle. Nail biting leads to injuries to the nails, cuticles, and skin surrounding the nails. These broken, jagged nails can now cause injury to delicate gum tissue. And to make things worse, fingernails harbor a lot of germs and bacteria, leading to the risk of illness and oral infections.  At the same time, bacteria from our mouths can get into the area around the injured nail, potentially leading to painful infections in the fingers.

• Bruxism

Studies have indicated that nail biters have a greater risk of bruxism. Bruxism, better known as tooth grinding, can lead to a number of serious problems over time. Grinding and even clenching teeth on a regular basis can cause chronic headaches, worn enamel, fractured teeth, broken dental restorations, receding and inflamed gums, and loose teeth.

• Breakage & Bad Bites

Your nails suffer obvious breakage, clearly, but your teeth are also at risk. The constant pressure of nail biting can lead to cracking, chipping, and erosion in the front teeth. Further, the pressure put on your teeth can even move them out of alignment, leading to bite problems. As you can imagine, nail biting has an even greater impact if you are wearing braces, because those teeth are already under pressure.

Why do we bite? Nail biting, or onychophagia, is a habit often started in childhood. Some people quit on their own as they reach adulthood, but for others, it can be a lifelong and painful habit. The explanations for nail biting are many: some researchers regard the habit as a form of compulsive behavior, others believe it to be a grooming impulse gone haywire, still others think it’s a way that we respond to anxiety or other stresses.

Whatever the cause, if you want to break the habit, you have options. There are over the counter polishes that use an unpleasant taste to deter biting. Learning to recognize triggers such as stress or boredom can help you choose a different response, such as snapping a rubber band around your wrist or gripping a stress ball. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can recommend some techniques for modifying this behavior. And finally, we can offer you suggestions for quitting, or even customize a mouthguard at our Kingston, ON office to discourage nail biting and prevent the problems that come with bruxism.

It’s never too late to quit. If nail biting has become more than a cosmetic problem, let’s work on a solution. Healthy, attractive nails are a great goal to work toward, but nothing beats a beautiful, healthy smile!
