We know that the foods we eat and drink can have a definite impact on our smiles. Staining is an unhappy side effect of many of our menu favorites. That’s why we sip red wine through a straw, rinse with water after a slice of blueberry pie, and cut back on the coffee and tea after a single cup (or two—we’re not perfect!). And sugar is the fuel for cavity-causing bacteria, so we try to substitute water for soda, or replace the hot fudge sundae with grilled fruit. And we always brush carefully after indulging.

So far, so good. But while we’re saving our brilliant smiles from stains and decay, let’s not forget one other source of diet-related damage—acids. Acidic foods and beverages can actually erode the surface of our enamel, leaving our teeth more vulnerable to sensitivity and discoloration.

What Is Dental Erosion?

Enamel is the strongest substance in our bodies—stronger than bone—but it is not indestructible. And acids are one of the major causes of enamel damage. (In fact, it’s the acids produced by bacteria that lead to cavities.) Luckily, our bodies are designed to protect our enamel. Saliva helps clean the teeth by washing away food particles and it neutralizes acidity as well. But a diet that’s too heavy in acidic foods can undo all this good work and upset the healthy pH balance in our mouths.

Why is this a problem? Because acidic environments actually cause the minerals in our enamel to break down, a process known as “demineralization.” This weakening of the enamel leaves teeth more sensitive to heat and cold. It can even lead to discolored teeth, as thinner enamel allows the brownish-yellow dentin underneath the enamel surface to become visible.

Are You Aware of Acids?

We can immediately guess at some of the most acidic foods. Citrus fruits and juices, tomatoes in their many culinary forms, anything pickled in vinegar, coffee, tea, wine—these foods are certainly acidic, but also a regular part of many a healthy diet. You don’t need to avoid these foods altogether, but it’s best to enjoy them as part of a meal or enjoy them sparingly. And balance out some of these high-acidity foods at mealtime with low-acidity choices like bananas, bread, and dairy products.

Other sources of damaging acids might surprise you. Studies have linked sodas, energy drinks, and sports drinks to higher levels of tooth erosion. The combination of citric acid, phosphoric acid and/or carbonation raises acidity levels in the mouth. And because we tend to sip them all day long, it’s like a continuing acid bath for our enamel. Water is always a healthy alternative for hydration, but if you do indulge in a soda or sports drink, rinse with water after drinking. And don’t swish—just swallow.

Won’t Brushing Help?

Yes, but watch your timing. Because the acids in foods weaken enamel, brushing right after a big glass of orange juice or a soda can actually be even more abrasive for tooth surfaces. We recommend waiting anywhere from 20-60 minutes to brush. This gives your saliva the chance to not only wash away acids, but to “remineralize” your teeth, bathing them in the phosphate and calcium ions that strengthen enamel.

If you notice any of the symptoms of dental erosion, including pain, sensitivity when you eat or drink something hot, cold or sweet, or yellow discoloration, talk to Dr. Michael DeWeerd during your visit to our Wayland, MI office about what you can do to help protect and strengthen your teeth. Unfortunately, our bodies can’t produce new enamel. By avoiding foods that stain, by reducing sugars that lead to decay, and by limiting the acidic foods that erode our enamel, we give ourselves the best opportunity for a lifetime of beautiful, healthy smiles.

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 Dr. Michael DeWeerd when you visit our Wayland, MI 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.

If you have been thinking about getting a piercing, or if you already have one or more, there are some health risks our team at DeWeerd Dentistry wants you to know about. It's important to know the risks involved with oral piercing, including infection, chipped teeth, gum damage, nerve damage, loss of taste, or tooth loss that could occur as a result.

Your mouth contains millions of bacteria, and infection is a common complication of oral piercing. Many people who have piercings tend to regularly touch them, paving the way for bacteria to enter piercing sites. Also, food particles that collect around piercing sites can lead to infection.

Besides hindering your ability to talk and eat, oral piercing also leads people to develop a habit of biting or playing with their piercings, which can lead to cracked or fractured teeth. While the fracture can be confined to the enamel of the tooth and require a simple filling, you also run the risk of the fracture going deep into the tooth, which may require a root canal, tooth extraction, and additional dental treatment.

If you still decide to get an oral piercing, you should realize that it will take some time to heal (anywhere between four to six weeks) and it may be very uncomfortable. Also please keep in mind that it will be an added responsibility to your life, as it will require regular upkeep. We want you to make sure that you’re committed to the task of taking care of it for the full healing period and beyond.

We encourage you to clean the piercing with antiseptic mouthwash after eating, and brush the jewelry each time you brush your teeth. If you have any questions, please don't hesitate to give us a call!
