Getting a cavity seems like delayed punishment for eating that special dessert every weekend or for the few days you forgot to floss. When you are doing everything right with minimal exception and a cavity is diagnosed, it is discouraging. Knowing how cavities form and what causes them is valuable in knowing how to prevent them. In this blog post, Dr. Chad Vanourny will help you understand cavities!

A cavity is not a one-time event. It is actually a symptom of a disease called caries. Tooth decay is a result of an active infection and condition in the mouth. There are ingredients to this infection, which include bacteria, acid, your tooth, and a food source. The main bacterial culprit is S. Mutans. Bacteria live in a housing structure called biofilm. This offers them protection, food, and an ideal replicating environment.

Biofilm can be healthy if there is a balance of good bacteria. When you have caries, the numbers of “bad” bacteria increase and produce an environment where they thrive and therefore cause tooth decay. A main indicator of this is a pH measurement of your saliva.

Several factors can influence the biofilm pH. Foods and beverages all have different pH levels. The lower the number, the higher the acidity. Since acid promotes tooth decay, a beverage like soda will promote a cavity. Water, being neutral, is a good choice to promote healthy oral pH. Healthy eating can still cause cavities. Here is an example of a highly acidic, yet traditionally healthy meal:

Toast with store-bought strawberry jam, and a cup of cottage cheese topped with fresh cranberries.

Instead, here is a better choice, which involves mixing acidic healthy foods with alkaline (non-acidic) foods to reduce the overall pH:

Toast with almond butter, and Greek yogurt topped with fresh blueberries.

The first example will result in a very low pH in the mouth and even in the rest of the body. The second meal mixes highly acidic blueberries with an alkaline Greek yogurt. Dairy products from cows are highly acidic. Toast is acidic because of the yeast and almonds are alkaline.

A natural buffer is saliva. Whenever mouth breathing or medications compromise the saliva flow, the pH is going to drop and caries can go rampant. Getting a cavity is not just about the sweets or forgotten flossing sessions. It is about the pH levels and bacterial management.

Whew! It’s a hot one! And whenever the temperature soars, you need to stay hydrated, especially when you’re outside or exercising. But all cold drinks aren’t equal when it comes to healthy hydration. Which beverages shouldn’t have a prime spot in your cooler when you’re wearing braces or aligners?

• Soft Drinks

You’re probably not surprised to find soft drinks at the top of the list. After all, sugar is a) a big part of what makes soda so popular, and b) not a healthy choice for your teeth.

Sugar is a favorite food source for the oral bacteria that make up plaque. These bacteria convert sugar into acids, and these acids attack the surface of your tooth enamel. Over time, the minerals which keep enamel strong begin to erode, and weakened, eroded enamel is a lot more susceptible to cavities.

So, what about sugar-free drinks? Does this make soft drinks a better choice? Unfortunately, you can take the sugar out of many sodas, but you can’t take the acids out. Most soft drinks are very acidic, even without sugar, and will cause enamel erosion just like the acids created by bacteria will.

• Fruit Drinks

Fruit juice provides us with vitamins, which is great, but it’s also full of natural sugars and acids. And blended fruit drinks and fruit punches often contain added sugars and added citric acids. Best to choose 100% fruit content and check the labels before you buy. (And you can always get refreshing fruit flavor by adding a slice of fruit to a glass of water.)

• Sports Drinks

You might be surprised to see these on the list—after all, they promise healthy hydration while you’re working out. And hydration is healthy—but sugars and acids aren’t. Even when the label tells you there’s no added sugar, that same label will often reveal high amounts of citric acid. In fact, some sports drinks are more acidic than sodas.

We’ll make an exception, though, for thirsty people who participate in sports or activities that require a lot of physical exercise and produce a lot of sweat. When we sweat, we lose electrolytes, those ionized minerals which help regulate many vital bodily functions. Talk to Dr. Chad Vanourny about which sports drinks are best for you if you need to replenish your electrolytes when working out.

So, what’s your best hydration choice on a hot day? Water! It not only hydrates you, it cleans your teeth, it helps you produce saliva, and it often contains tooth-strengthening fluoride. But if you only have sports drinks in the cooler, or if you just want to enjoy a soft drink or a bottle of juice from time to time, no need to go thirsty. We have some ways to make sure your teeth are safer, even with this tricky trio:

• Rinse with water after you drink a sugary or acidic drink. And remember to brush when you get home.
• Be choosy. Check labels for added sugars and acids.
• Don’t sip your drinks all day long. Saliva actually helps neutralize acids in the mouth, but sipping acidic beverages throughout the day doesn’t give saliva a chance to work.
• Use a straw to avoid washing your enamel in sugars and acids.

You need to keep hydrated when it’s hot. When you’re packing your cooler, choose drinks that are healthy for your entire body, including your teeth and gums. Ask our Charlotte team for the best choices in cold drinks to make sure you’re getting the hydration you need—without the sugar and acids you don’t!

Come say hello twice a year. The American Dental Association says two times is the charm. Multiple visits a year lets us keep an eye out for any developing issues. It’s important to remember that this goes for the whole family. Children over one year old should be seeing Dr. Chad Vanourny!

Stay fresh. At Catawba Valley Dental Care, we have a virtually unlimited stock of toothbrushes and floss, which means you have no excuse to be using a sad, ineffective toothbrush. As soon as bristles begin to fray, pick up a new one or stop by our Charlotte office and we’ll replace yours. On average, you should be opening a new one every two to three months.

For goodness sake, floss! Flossing is an efficient way to keep your whole mouth healthy. It not only protects your teeth by removing aggregated plaque, it keeps your gums happy, too.

And brush. Practicing regular healthy habits is essential to keeping your mouth—and us—happy! When it comes to brushing that means two minutes, two times a day. If your kids need some encouragement, try making a calendar or playing a song like this.

Tell a friend. One way you can help us is by spreading the love. Tell your friends about what a good thing we’ve got going here. The more the merrier. And the healthier.

We’re parents, so we worry. It comes with the job description! That’s why we make sure our children use toothbrushes with soft bristles and apply just the right amount of fluoride toothpaste. That’s why we make regular appointments with their dentists for preventive care and examinations. And that’s why we want to know all about the X-rays that are used in our children’s dental exams.

First of all, it’s reassuring to know that the amount of radiation we are exposed to from a single dental X-ray is very small. A set of bitewing X-rays, for example, exposes us to an amount of radiation that is approximately the same as the amount of radiation we receive from our natural surroundings in a single day.

Even so, dentists are especially careful when children need X-rays, because their bodies are still growing and their cells are developing more rapidly than adults. And children often have different dental needs than adults, which can require different types of imaging.

In addition to the usual X-rays that are taken to discover cavities, fractures, or other problems, young patients might need X-rays:

• To confirm that their teeth and jaws are developing properly
• To make sure, as permanent teeth come in, that baby teeth aren’t interfering with the arrival and position of adult teeth, and that there’s enough space in the jaw to accommodate them
• To plan orthodontic treatment
• To check the progress and placement of wisdom teeth

So, how do dentists make sure your child’s radiation exposure during X-ray procedures is as minimal as possible?

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

Moreover, radiologists are devoted to raising awareness about the latest advances in imaging safety not only for dental and medical practitioners, but for the public, as well. With children in mind, pediatric radiologists from a number of professional associations have joined together to create the Image Gently Alliance, offering specific guidelines for the specific needs of young patients.

And because we are always concerned about the safety of our patients, dental associations around the world, including the American Academy of Pediatric Dentistry, the American Dental Association, the American Dental Hygienists’ Association, the Canadian Academy of Pediatric Dentistry, and the Canadian Dental Hygienists Association, are Image Gently Alliance members.

The guidelines recommended for X-rays and other imaging for young people have been designed to make sure all children have the safest experience possible whenever they visit the dentist or the doctor. As dental professionals, Dr. Chad Vanourny and our team ensure that imaging is safe and effective in a number of ways:

• We take X-rays only when they are necessary.
• We provide protective gear, such as apron shields and thyroid collars, whenever needed.
• We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
• We set exposure times based on each child’s size and age, using the fastest film or digital image receptors.

We know your child’s health and safety are always on your mind, so you’re proactive about dental care. And your child’s health and safety are always on our minds, too, so we’re proactive when it comes to all of our dental procedures available at our Charlotte office.

Please free to talk with Dr. Chad Vanourny about X-rays and any other imaging we recommend for your child. We want to put your mind at ease, knowing that X-rays will be taken only when necessary, will be geared to your child’s age and weight, and will be used with protective equipment in place. Because ensuring your child’s dental health and safety? That comes with our job description!
