Why Do Molars Seem to Get More Cavities?

February 17th, 2021

Probably because, for many kids, molars do get more cavities. So let’s answer two better questions: Why do molars get more cavities? And, how can we help prevent them?

It’s the Pits. (And Fissures.)

The reason molars are so useful—and more likely to develop cavities—is because of their shape. Unlike our front teeth, which are used to bite through foods, molars are used to grind and chew. That’s why they are so much larger, with a flat surface on top. Well, not exactly flat.

When you look at a molar, you’ll notice that the top isn’t really smooth at all. It’s covered with little indentations known as pits and longer grooves called fissures. These irregular features both trap food particles and make it more difficult for bristles to clean them away. Cavities in molar surfaces are so common that they even have a specific name: “pit and fissure cavities.”

But molar biology does not mean tooth decay is inevitable! There are steps you can take to protect your children’s molars as they grow, while you’re providing them with dental strategies that will keep their adult molars healthy and cavity-free.

Preventing Pit and Fissure Cavities

  • Don’t Just Brush—Brush Effectively

The first step in preventing any kind of cavity is brushing properly. Your child should be brushing at least two minutes, at least twice each day. And while the time we spend brushing is important, technique is also key.

When you’re showing your child how to brush, be sure that the tops of molars, upper and lower, get brushed thoroughly, with special emphasis on cleaning pits and fissures. Make sure the toothbrush is small enough to fit your child’s mouth comfortably and reach all the tooth surfaces. Replace worn-down brushes or electric toothbrush heads after three to four months when they no longer clean as effectively.

Your child will probably need adult supervision from toddler years through the early years of grade school to learn how to brush properly. This is time well spent, as your child learns cavity-preventing brushing techniques which will last a lifetime.

  • Eat a Tooth-Healthy Diet

Plaque bacteria use the sugars in our food to make acids. These acids break down the mineral strength of tooth enamel and eventually lead to cavities. And because pits and fissures are great hiding places for bacteria and food particles (especially sticky ones), molars are even more at risk for cavities. Limiting sugary, sticky foods like sweet treats and simple carbs helps reduce that risk.

Acidic foods like flavored juices, sour candies, sodas, and power drinks also weaken enamel and can leave teeth more vulnerable to decay. Help your child avoid cavities by limiting acidic foods and drinks, making them part of a balanced meal, and/or rinsing with water after eating.

  • Use Fluoride Toothpaste

Fluoride toothpaste not only reduces the risk of cavities, it also helps strengthen enamel that has been weakened by bacterial and dietary acids. Win-win!

  • Ask About Sealants

Sealants are invisible, safe coatings which protect molars by preventing food and bacteria from getting trapped in their uneven surfaces. The top of the molar is first treated with an etching solution to allow the sealant to bond tightly to the tooth, a thin coat of sealant is painted on, and then it’s hardened under a curing light. That’s all there is to it.

Sealants are often recommended when children’s permanent molars first erupt, when they are especially at risk for cavities. Sealants can last from three to five years (or even longer), and studies have shown a dramatic reduction in cavities for patients who use sealants compared to patients with untreated teeth. Depending on your child’s individual needs, Dr. Guijon might recommend a sealant for baby molars as well.

  • Regular Exams and Cleanings

It might be hard for you to tell if your child’s molars have been affected by sticky plaque, or sugary foods, or acidic drinks, or inadequate brushing, or any other potential cavity-causers. It’s not a difficult job for Dr. Guijon, though! Through regular checkups and cleanings at our Huntington Beach, CA office, we will discover any conditions that might lead to cavities, and, if necessary, treat small cavities before they lead to more serious decay.

Statistically, childhood molars have a greater chance of developing cavities than incisors and canines. Help your child beat the odds by understanding why these teeth are at risk and by working with your dental team to give your child years of healthy teeth now and a future filled with beautiful smiles!

Dental Veneers

February 10th, 2021

If you want to fix staining, large gaps, fillings, chipped teeth, or the overall shape of your teeth, this may be the perfect option for you. Many of our patients opted for veneers and have never been more confident in their smile!

Dental veneers are made from long-lasting porcelain materials which cover the front and biting ends of each tooth. At your appointment, you can choose the shade of veneers to brighten up your smile. They are usually placed on the anterior, or front teeth, where the chewing forces are not as hard as in the back. Placing the veneers is easy, and the best part is: It requires only two appointments!

During the first appointment, we’ll take an impressions of your teeth. Then we send them to the lab to make your veneers. Veneers are fairly conservative in preparation because they require a small amount of space to be created on the front, bottom, and sides of each tooth for a natural appearance. You will leave the office with temporary veneers in place for a week or two while the permanent veneers are being made.

Your veneers will be placed during the second appointment, and you won’t believe the difference in your smile! If you’re interested in learning more, give Dr. Guijon a call at our Huntington Beach, CA office today!

My child has canker sores! How can I help?

February 3rd, 2021

According to the American Association of Pediatric Density, roughly one in five children suffers from canker sores. Canker sores are small sores that appear inside the cheeks, on the lips, on the surface of the gums, and under the tongue.

Even though, canker sores are not contagious, they do tend to run in families. There are several reasons your child may be suffering from canker sores including:

  • Children who have Vitamin B12, iron, and folic acid deficiencies tend to get canker sores more often than children who have normal levels of these vitamins and minerals.
  • Children who suffer from food allergies are also at a higher risk for developing canker sores. It’s difficult to determine what your child may be allergic to. If you feel strongly that the canker sores are related to an allergy, then a visit to an allergist is highly recommended.
  • Biting their lip or cheek can also result in a canker sore.
  • Any injury to mouth, where the skin breaks can cause a canker sore.
  • Brushing their teeth too hard can also be a problem.
  • Your child may be sensitive to an ingredient in their toothpaste. Try switching toothpastes and see if it makes a difference.
  • Emotional disturbances and stress are also factors to consider.

If your child has frequent canker sores a visit to our Huntington Beach, CA office will be beneficial. Canker sores are painful and usually last about 14 days. Dr. Guijon may recommend one or a few of the following treatment options:

  • Avoid food that is acidic, salty, and spicy.
  • A toothbrush with soft bristles may be helpful.
  • Avoid mouthwash and toothpaste that contain SLS.
  • Do not feed your child foods that they may be allergic to.

Canker Sore Remedies

  • Eating yogurt that contains Acidophilus will relieve the pain and help the canker sore heal faster.
  • Put one teaspoon of baking soda in an eight-ounce glass of lukewarm water. Have your child gargle and swish it around his or her mouth several times a day. Not only does this remedy relieve the pain, the canker sore could be gone in as little as 24 hours.
  • Place a wet tea bag on the sore and hold it there for a few minutes several times a day. This remedy will help with the pain and quickly heal the sore.
  • Camphor, Benzocaine, Lidocaine, and Orajel are over-the-counter medications that can help.

If you have questions about your child’s canker sore, contact Dr. Guijon to schedule an appointment.

Balancing Act

January 27th, 2021

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. Guijon when you visit our Huntington Beach, 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.
