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 Karina Gregg during your visit to our San Marcos, CA 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.

Poor April. While other months celebrate romance, or giving thanks, or costumes and candy, April has—April Fool’s Day and a tax deadline. We might be forgiven for thinking these two dates seem more like warnings than celebrations.

So here’s a new topic for the April calendar: National Facial Protection Month! Take the opportunity this month to review your safety practices while you’re enjoying your favorite activities.

• Mouthguards

If you have a mouthguard for sports or athletic activities, wear it! In any activity or sport where humans come into contact with solid objects (including other humans) tooth injury is possible. A mouthguard will help protect you from dental injuries caused by falls, physical contact, or other accidents that might happen in your active life. And it’s not just your teeth—mouthguards protect your lips, tongue, and jaw as well.

You can buy mouthguards in stock sizes or shape-to-fit options, or you can have a guard custom made especially for you at our San Marcos, CA office. Custom mouthguards fit perfectly and are designed to make breathing and speaking easy and comfortable. And if you wear braces or have fixed dental work such as a bridge, a custom mouthguard can protect your smile and your appliances. Talk to Dr Karina Gregg about mouthguards for some great advice on how to protect your teeth and mouth.

As long as we’re discussing facial protection, let’s look at some other ways to keep safe as you keep active.

• Helmets

If there’s a helmet available for your sport, use it! Helmets are especially important for protecting athletes from brain injury and concussion, and they help protect the face and jaw as well.

• Face Guards

If you’ve experienced a puck speeding toward you, or a defensive tackle hurtling your way, or a fast ball coming in at 90 miles an hour, you know the importance of wearing a face guard. These guards can help protect your eyes, face, teeth, and jaws. Many sports now recommend using face guards—it’s worth checking to see if your sport is one of them.

• Eye Protection

And let’s not forget eye protection. Whether it’s safety glasses or a visor, protecting your eyes and the bones around them is extremely important. You can even get sports goggles or protective sports glasses with prescription lenses to keep you safe and seeing clearly.

We have the training and experience to help treat and restore injured teeth. But we will be the first to tell you, the very best treatment is prevention!

So here are a few suggestions for your calendar this month:

• If you haven’t gotten a mouthguard yet, now’s the time. Tooth and mouth injuries occur in sports beyond hockey and football. If you play basketball, ski, skateboard, ride a bike—in fact, almost any sport where you can fall or make contact with a person or object—a mouthguard is a must.
• If you need to replace an ill-fitting or damaged helmet and face guard, do it before your next game. And do replace a bike helmet if you’ve been in a crash—most likely it won’t be as protective, even if damage isn’t visible.
• Talk to your eye doctor about protective eyewear if off-the-rack products don’t work for you.
• If you are a parent or caregiver, make sure your child athlete has the proper facial protection—and uses it.
• If you are a coach, make sure your athletes have the right protective gear—and wear it.
• It’s also a great time to commit to using your protective gear every single time you’re active.

But, wait—these reminders are helpful and important, but weren’t we promised something to celebrate this April? Good catch! The great news is, using facial protection for sports and athletic activities gives you rewards you can celebrate all year: fewer injuries, fewer visits to the emergency room, and a beautiful, healthy, intact smile. Suit up!

Let’s face it, by now, brushing our teeth is something we pretty much do on auto-pilot. A quick brush after breakfast, a minute or so at night, floss when we think of it. Done. But take a few minutes to review these cleaning tips, and see if a few small adjustments to your routine could make all the difference at your next checkup at our San Marcos, CA office.

• Tools

Some of us prefer brushing with a manual brush. Some like the electric brush for ease and comfort. Whichever form of brush you choose, be sure that it fits comfortably in your mouth, reaches everywhere it needs to, and has a handle that is easy to grip. There are many bristle options available, so if you are an energetic brusher, or if you have sensitive gums, try a soft bristled brush for gentler brushing.

If you haven’t been exploring the floss aisle lately, there are now many varieties available to suit your particular needs. Besides the traditional floss, there are coated flosses for easy gliding between teeth that fit closely together, dental tape-style flosses to fit teeth with wider spacing, and even flosses designed just for braces that thread between the wires and brackets. Talk to Dr Karina Gregg at your next cleaning for product suggestions if you think there’s an easier, more comfortable option out there for you.

• Technique

With proper technique, any toothbrush and floss you choose will do a fine job of removing plaque.

Brushing? There’s a tried and true method for success. Place the toothbrush at a 45° angle at the gum line. Be sure to brush the outside, inside, and chewing surface of each tooth thoroughly. Remember the expression, “Massage, don’t scrub.” Over-vigorous brushing can actually irritate gum tissue and damage enamel. An electric toothbrush should provide a continuous brushing motion without needing any pressure from the brusher. This might be the model for you if you have a too-vigorous approach to brushing, or sensitive teeth and gums. If you like your manual brush, again, give a soft-bristled brush a try!

As for flossing? That harmless-looking little string can cause gum damage if used too forcefully. You can accomplish the placement and cleaning power you need by easing the floss down to the gumline and flossing with gentle pressure against the tooth surface. If you have any questions about technique, remember—we are always happy to let you know the best cleaning methods for your specific needs.

• Timing

Of course, the best tools and the best technique in the world won’t be effective unless you put the right amount of time into brushing and flossing.

The standard rule is two minutes of brushing in the morning and two minutes at night. If you wear braces or have other special circumstances, we might recommend brushing after every meal. And if you brush after breakfast, give your teeth half an hour or so to remineralize. This natural process uses the calcium and phosphate ions in your saliva to strengthen tooth enamel after it’s been exposed to any acidic foods in your breakfast.

Thorough flossing can be accomplished in a few minutes, and might be needed only once a day. But again, depending on your individual needs, we might have other recommendations. Let’s review what works for you at your next visit—we can tailor suggestions for a brushing routine to your unique needs.

It’s a great idea to review your brushing habits periodically to make sure you are getting the most out of those minutes you spend cleaning your teeth. There won’t be a test at the end of this review, and you won’t get a gratifying grade or a gold star. What you will get is much more important—better checkups, fewer cavities, and healthy teeth and gums. Happy cleaning!

In years past, it was often recommended that dental patients who had a history of heart problems or other conditions, such as joint implants, be given antibiotics before any dental work. This pre-treatment is called prophylaxis, based on the Greek words for “protecting beforehand.” Why would Dr Karina Gregg suggest this protection? It has to do with possible effects of oral bacteria on the rest of the body.

Our bodies are home to bacteria which are common in our mouths, but which can be dangerous elsewhere. If these oral bacteria get into the bloodstream, they can collect around the heart valve, the heart lining, or blood vessels. A rare, but often extremely serious, infection called infective endocarditis can result.

It is no longer recommended that every patient with a heart condition take antibiotics before dental procedures. Doctors worry about adverse effects from antibiotics or, more generally, that an overuse of antibiotics in the general population will lead to more strains of antibiotic-resistant bacteria.

There are some patients, however, who are at a higher risk of developing infective endocarditis, and who should always use preventative antibiotics. Generally, premedication is advised if you have one of these risk factors:

• A history of infective endocarditis
• Certain congenital heart conditions (heart conditions present since birth)
• An artificial heart valve
• A heart transplant

Your cardiologist will know if prophylaxis is advisable, and if you are taking any drugs which could interact with antibiotics. Always talk to your doctor about any dental procedures you are planning, particularly if they are invasive procedures such as gum surgery or extractions.

If you believe you would benefit from antibiotics before dental treatment at our San Marcos, CA office, the most important first step is to talk with your doctors. We are trained to know which pre-existing health conditions call for prophylaxis, which dental procedures require them, which antibiotics to use, and when to take them. Tell us about any health conditions you have, especially cardiac or vascular issues, and any medication allergies. Working with you and your doctor to protect your health is our first priority, and having a complete picture of your medical health will let us know if antibiotic prophylaxis is right for you.
