We’re all trying to find a healthy balance in our lives. Balancing work and home life. Eating a well-balanced diet. Balancing our budgets. Maintaining the right pH balance in our mouths for better dental health. Wait, what was that last one?

You probably don’t spend a lot of time thinking about your pH levels, but if your oral pH is out of balance it can affect the health of your teeth.

What do we mean by pH levels? In biology and chemistry, the pH scale is a tool used to measure the concentration of hydrogen (H⁺) ions and hydroxide (OH⁻) ions in a solution.  

The higher the concentration of hydrogen atoms, the more acidic a solution. The higher the concentration of hydroxide ions, the more alkaline. The pH scale goes from 0 to 14, with the most acidic reading possible rating a 0, and the most alkaline, a 14.

You don’t have to be a biochemist to use the information provided by pH samples. We use pH readings to discover the ideal acid/alkaline conditions in many everyday applications. Azaleas grow best in very acidic soil. Swimming pools should be just a bit alkaline. Brewers test pH throughout the beer-making process for optimal fermentation—and taste.

When it comes to saliva, a neutral pH range of around 6.2 to 7.6 is generally considered normal. High alkalinity in saliva is rare. High acidity levels? Unfortunately, much more common. And an acidic environment has real-world consequences for teeth.

Plaque contains bacteria, which produce acids. Calcium and phosphate, the minerals that help make enamel the strongest substance in the body, are leached out by these acids. The weak spots left behind make enamel vulnerable to further erosion and, eventually, decay. When saliva has a normal, neutral pH, it helps neutralize plaque acids to reduce the risk of cavities.

But it’s not just bacteria that expose our teeth to acidic conditions—we do it ourselves with our choice of food and drink.

Acidic foods can directly lower the pH level in saliva. Lemon juice, for example, has a pH between 2 and 3. Red wine has a pH between 3 and 4. Blueberries? Around a 3.2. When the pH level in saliva becomes 5.5 or lower, the minerals in our teeth start to “demineralize,” or lose the minerals which keep enamel strong and intact—just the way enamel is demineralized by acids from plaque. This process is known as acid erosion.

Many of our favorite foods are acidic to some degree. Citrus and other fruits, pickled foods, vinegar, wine, coffee, tea—all of them can lower the optimal pH level of saliva. And sports drinks, energy drinks, and sodas? Check the labels and you’ll often find citric acid, phosphoric acid, and/or carbonation, all of which combine to create extremely erosive conditions.

So, no more soda? Or fruit? No. You don’t have to give up acidic foods altogether for healthy teeth. True, you won’t give up much eliminating soda from your diet. But fruits, vegetables, dairy foods, and meats are the source of essential vitamins, minerals, and proteins, and many of these healthy food choices have an acidic pH. How to eat nutritiously while protecting your enamel? Again, it’s a balancing act.

• Enjoy acidic foods sparingly, or as part of a meal. Saliva can neutralize acids more effectively when they aren’t washing over your teeth all through the day.
• Use a straw when you drink something with a low pH to reduce your enamel’s exposure to acids.
• Balance high-acid foods with low-acid choices to help neutralize the acids in your diet. Add a banana to your blueberry smoothie. Pair your wine with some cheese.
• Rinse with water after eating or drinking. When it comes to balanced pH, pure water is a 7.0 on the scale, a perfect neutral.
• Chew sugarless gum to increase saliva production.
• Use fluoride toothpaste—it not only helps prevent cavities, it helps remineralize teeth.

Even with your best efforts, acid erosion can be a problem. You might be experiencing enamel damage if you notice any of these symptoms:

• Tooth pain or sensitivity.
• Teeth that appear discolored. This happens as the whiter enamel thins, revealing the yellowish dentin underneath.
• Changes in the shape of your enamel—your teeth become rounded or have little dents or pits, known as cupping.
• White spots on your teeth, which could be a sign of demineralization.

If you think you could be suffering from enamel erosion, it’s a good idea to talk to Drs. Rottschalk, Acker, and Froidcoeur when you visit our Fairview Heights, IL office. We can diagnose conditions causing acid erosion, treat you if enamel damage has occurred, and offer suggestions for diet and eating habits to make sure your oral pH—and your dental health—is always in balance.

We’re all friends here, so if you sometimes feel a bit nervous before your dental appointment, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your experience can be. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes patients feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is termed radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs.  

There are different types of common dental X-rays which are used for a number of reasons:

• Bitewing X-rays, which are used to check on the health of the back teeth.
• Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
• Occlusal X-rays, which show the entire arch of teeth in the upper or lower jaw.
• Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
• Cone Beam Computed Tomography, an external device which uses digital images to create a three-dimensional picture of the teeth and jaws.

Why Do We Need X-rays?

If all of our dental conditions were visible on the surface, there would be no need for X-rays. But there are many conditions that can only be discovered with the use of imaging—infection, decay, a decrease in bone density, or injuries, for example, can show up as darker areas in the teeth or jaws. Among their many diagnostic uses, X-rays can help us find:

• Cavities between teeth or under old fillings
• Damage to the tooth’s pulp which might require root canal treatment
• Injuries to teeth or roots after trauma
• Abscesses, tumors, or other conditions that might be causing swelling or pain
• Position and development of wisdom teeth
• Ideal placement for implants
• Health and density of the jaw and alveolar bone

X-rays can also serve an important preventative role, by discovering small problems before they become major ones.

How Do Dentists Make Sure Your X-rays Are As Safe As They Can Be?

First of all, the amount of radiation you are exposed to with a dental X-ray is very small. In fact, a set of bitewing X-rays exposes us to slightly less than the amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Drs. Rottschalk, Acker, and Froidcoeur and our team are committed to making sure patients are exposed to as little radiation 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.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We 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.
• When treating children, we set exposure times based on each child’s size and age.

And now that we’ve talked about some things you might like to know,

Please Let Us Know If . . .

• You’re a new patient, with previous X-rays taken during regular exams or for specific procedures. Ask to have your older X-rays sent to our office. With digital X-ray technology, this transfer can be accomplished with e-mail! Having your dental history available lets us notice any changes that have taken place.
• You’re pregnant, or think you might be pregnant. Even though radiation exposure is very low with dental radiographs, unless there is a dental emergency, dentists and doctors recommend against X-rays for pregnant patients.

X-rays play an important part in helping us make sure your teeth stay their healthiest. If you have any concerns, contact our Fairview Heights, IL office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!

Drs. Rottschalk, Acker, and Froidcoeur and our team want you to have the healthiest possible smile in the healthiest possible body. Oral cancer can affect the mouth, tongue, throat and jaw. Early detection is vital for the best possible outcome when treating this disease. That is why we check for symptoms of oral cancer at every dental examination.

What can you do to reduce the chance of oral cancer?  Reduce your risk factors. You can help prevent oral cancer by adopting these healthy habits:

• Don’t smoke. Don’t chew tobacco. Don’t use a pipe. If you use any tobacco products, quit. Tobacco use is the single largest risk factor for head and neck cancers. Talk to us—we have suggestions for helping you break the habit.
• Drink alcohol in moderation. Heavy drinkers have a higher rate of oral cancer. More than one to two drinks per day can be considered heavy drinking, depending on factors such as weight, age, and even gender. Check with your doctor to find your personal definition of moderation.
• Eat a healthy diet. Cancer-fighting fruits and vegetables are a great addition to any menu.
• Protect yourself from the sun. Help prevent sun-related lip cancers by always wearing a UVA/UVB blocking sun screen or lip balm whenever you are working or playing outside—and reapply frequently.
• Some forms of the HPV virus have been linked to oral cancer, and those affected are generally younger and less likely to be smokers. Research indicates that the HPV vaccine, known for preventing several types of cancer, might also help prevent HPV-related oral cancers.
• Schedule regular dental exams. We are trained to recognize oral cancer and precancerous conditions that you might miss.

Of course, cancer can occur even with the healthiest habits. Do come see us if you detect any of these symptoms:

• A sore or ulcer that doesn’t heal, or persistent tenderness and pain in the mouth
• Lingering sore throat, hoarseness, or vocal changes
• Pain in the neck or ear that doesn’t go away
• A lump, a rough or thickened area, or eroded tissue in the skin lining the mouth
• Red or white patches in the lining of the mouth or on the tongue
• Difficulties chewing, swallowing, speaking, or moving the tongue or jaw
• Numbness in the tongue or mouth
• Changes in the way your natural teeth or your dentures fit together.

Not every symptom is caused by cancer, but it is important to rule out the possibility. We are trained to recognize early signs of oral cancer, and can recommend further tests if needed. Call our Fairview Heights, IL office immediately if you have any concerns. Early detection and treatment lead to the most successful outcomes.  

If you participate in sports or other physical activities, it’s wise to consider getting a mouthguard. Also known as mouth protectors, mouthguards are a device worn over the teeth to lessen the impact of a blow to the face.

This reduces the chance that you might lose teeth or sustain other serious oral injuries. We recommend that all patients involved in a contact sport such as wrestling, football, or hockey wear a mouthguard because of the high risk of such injuries.

However, anyone involved in a physically demanding sport or activity should wear a mouthguard as well.

Can you imagine what it would be like to lose a few of your front teeth? The way you talk, eat, and smile would all change. Potential injuries when you don’t wear a mouthguard include chipped and broken teeth, fractured jaws, root damage, damage to crowns and bridgework, concussions, and/or injury to the lips, cheeks, or gums.

Types of Mouthguards

There are three different types of mouthguards — typically made of a soft plastic material or laminate. You can decide which works best for you in terms of budget, fit, and comfort.

• Stock mouthguards are prefabricated to a standard size. They offer adequate protection, but you need to make sure you find one that fits properly and comfortably. Stock mouthguards are readily available at department stores, sporting goods stores, and online.
• Boil-and-bite mouthguards are placed in boiling water to soften them, then into the mouth so they can conform to the shape of the teeth. Boil-and-bite mouthguards are more expensive, but offer a more customized fit than stock ones. You can find these in department stores, pharmacies, sporting goods stores, and online.
• Custom-made mouthguards are created just for you by Drs. Rottschalk, Acker, and Froidcoeur. These offer the best fit and comfort of all the options, but they are also the most expensive. Ask a member of our Fairview Heights, IL team for more information.

The American Dental Association says a good mouthguard should be easy to clean, fit properly, be comfortable, and resist tearing or damage. It shouldn’t restrict speech or breathing.

Still not sure if you need a mouthguard or which kind is right for you? Ask Drs. Rottschalk, Acker, and Froidcoeur or one of our staff members for more information.
