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 Karina Gregg when you visit our San Marcos, CA 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.

Whether you already miss the sun’s bright rays, or can’t wait for some cool, crisp weather and colorful leaves, summer is making way for fall. And the change of seasons might mean it’s time for some adjustments to your dental care routine.

Fall’s in the Air, and You Can Feel It

You might enjoy the brisk weather and the cool autumn breezes, but you’d enjoy fall much more without the tooth sensitivity that cold weather can bring. Sensitivity can be the sign of a cracked tooth, gum disease, or even something as simple as too-energetic brushing. If you’re experiencing sensitivity outdoors or with hot and cold foods, don’t give up your nature walks and hot cider! Give Dr Karina Gregg a call, and we’ll get to the root of your problem.

Fall Sports

The baseball mitts, surfboards, and water skis have been retired for the year, but that won’t stop you from enjoying exercise and team sports. And while you’re keeping your body healthy, remember to keep your teeth and jaws healthy as well. A mouth guard is an essential piece of equipment for any autumn contact sport like football or soccer, and is also a good idea for biking, skateboarding, and other physical activities where a fall or a collision is a possibility.

Fall Feasts

‘Tis the season for sugary Halloween treats, bountiful Thanksgiving desserts, and those over-the-top holiday lattes. By all means, celebrate the season. And celebrate your dental health (and your overall health) as well by enjoying these treats in moderation.

Why not take this opportunity to explore some of autumn’s more nutritious seasonal offerings? Brussels sprouts, sweet potatoes, carrots, pumpkins, and apples are part of a fall harvest of fruits and vegetables rich in vitamin A, vitamin C, potassium, calcium, and other nutrients that help keep our teeth and gums their healthiest. (And if the pumpkins and apples make their way into pies, no one will complain.)

Fall Semester

Many schools require a dental exam before the start of the academic year. If you haven’t made an appointment for your child, now’s the time to do it! And don’t forget a professional cleaning to remove plaque and tartar. Nothing starts a school year off better than entering the classroom with a bright, healthy smile.

And don’t forget to call our San Marcos, CA office for your own regular checkup if it’s that time of year. Spring, summer, winter, fall—it’s always the right season for taking care of your dental health!

A lot of changes occur in a woman's body during pregnancy. Hormone fluctuations are responsible for many of those changes, including the need for additional attention to the teeth and gums. Women who are expecting are at an increased risk for oral health complications, including gingivitis and tooth decay, which can lead to irreversible damage. Fortunately, there are steps pregnant women can take to keep their teeth and gums in optimal health from the first trimester to delivery day. Today, Dr Karina Gregg and our team at San Elijo Dental thought we would share them.

At-home dental care

At-home dental care should not vary much from what you did prior to pregnancy. The American Dental Association recommends brushing at a minimum of twice per day using fluoridated toothpaste. Follow up with floss to keep bacteria from accumulating in hard-to-reach spaces.

Dental checkups

It is safe and recommended to continue visiting Dr Karina Gregg for routine dental checkups and cleanings during pregnancy. However, it is very important to inform Dr Karina Gregg about an existing pregnancy. Special steps must be taken to protect pregnant women from certain medications or X-ray radiation that could be harmful to a growing baby. On the other hand, avoiding teeth cleanings during pregnancy can lead to serious consequences, including advanced tooth decay and infection.

Food and cravings

It is no secret that pregnancy can cause a woman to crave specific foods. Sugary treats like candy, cookies, or sodas may satisfy a sweet tooth, but they can also cause serious dental problems when consumed frequently or without brushing afterward. Trade out these treats for naturally sweet fruits when possible, and never forget to brush and floss thoroughly after eating sugar-filled foods.

Signs of complications

It is important to know and recognize the signs of oral health problems during pregnancy; an early diagnosis usually translates to an easier, less-invasive treatment. Symptoms of potential problems include gums that easily bleed or are swollen, reddened, or painful. These are symptoms of gingivitis, which can lead to a receding gum line and tooth loss if left untreated.

Call our San Marcos, CA office if you experience any of these symptoms or pain in a tooth, loss of a tooth, a broken tooth, or bad breath that does not go away with brushing.

Children’s oral health differs from that of adults in a variety of ways. Dr Karina Gregg and our team want you to understand how you can provide the best care for your son or daughter’s teeth. It’s essential to understand what your child will need from you when it comes to his or her oral health in those first few years.

In-home dental care begins when your baby starts to show signs of developing the first tooth. We recommend that you bring your child to our San Marcos, CA office between the ages of one and two. Dr Karina Gregg will take a look at your child’s tooth development and gums during this first scheduled appointment.

The initial appointment with your little one is designed to get him or her accustomed to our office. We recommend allowing your child to be in the exam room alone with us during the first visit in order to become comfortable with our staff at an early age.

We will go over several general matters during your child’s first visit:

• Look for signs of decay or other tooth or gum problems
• Make sure your youngster doesn’t have gum disease or cavities
• Examine your child’s bite, and check for misalignment that could lead to problems in the future
• Clean the teeth, and apply fluoride if your son or daughter is old enough
• Talk to you about proper oral health care for your
• Give you some tips for brushing and flossing your child’s teeth
• Answer any questions you may have about caring for your little one’s teeth

Once your child is old enough for his or her first visit to the dentist, you should begin to schedule regular cleanings every six months. If any problems arise before a scheduled appointment, call our San Marcos, CA location and we will be happy to answer any questions you may have.

Remember, creating healthy oral health habits with your child early on is crucial. We’re here to guide you through this process and make sure your child is healthy and happy.
