Why Do Molars Seem to Get More Cavities?

November 9th, 2022

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. Jeffery Spahr and Dr. Janna Spahr 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. Jeffery Spahr and Dr. Janna Spahr, though! Through regular checkups and cleanings at our Lincoln, NE 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!

Getting Ready for Winter

November 2nd, 2022

Winter Is Coming.

Okay, that sounded a lot more dramatic in a popular fantasy series. But here in the real world, winter is coming as well, so let’s look at some easy steps you can take to keep your teeth and gums healthy during this icy season.

Remember to Hydrate

Dehydration is dangerous for your health in general, and it’s also bad for your dental health. A dry mouth is more vulnerable to gum disease and tooth decay because there’s less saliva to help maintain a healthy oral environment. Saliva helps wash away food particles and bacteria, works to neutralize the cavity-causing acids they produce, and strengthens tooth enamel with its mineral content.

Summer means heat and perspiration—two obvious causes of dehydration. Winter, though, has its own more subtle ways to dry you out.

  • Just as you lose moisture through summer perspiration, you lose moisture with a winter workout as well. That foggy cloud you see when you exhale outdoors? That’s water vapor leaving your body.
  • Cold weather means it’s time to kick up the heating system a few degrees. But unlike heated summer outdoor air, heated winter indoor air is not as humid, so it’s more drying.
  • Some of us just aren’t as thirsty during winter months, and so we don’t hydrate as regularly as we do in the summer. And while summer menus tend to offer foods like salad, fruits, and iced drinks which automatically provide us with a lot of water content, winter menus? Not so much. Keep up with your daily recommended amount of water throughout the year for a healthier body and healthier teeth and gums.

Wear Your Mouthguard

Whether it’s skiing, hockey, snowboarding, or skating, those winter sports can be hard on your teeth. That’s why it’s important to wear your mouthguard when you’re getting the most out of the snow and ice. Mouthguards help prevent injuries to your teeth and provide protection for your jaw and mouth, too.

And a sport doesn’t have to involve snow and ice to be a winter hazard for your teeth. The combination of hard courts, flying elbows, and body contact make basketball a leader in the dental injuries competition. In fact, any sport which involves potential falls or personal contact is a good candidate for a mouthguard.

Mouthguards are available in several forms:

  • One-size-fits-all, pre-formed mouthguards can be found in drugstores and sporting goods stores.
  • “Boil-and-bite” models are warmed in hot water and then shaped when you bite down. The fit is somewhat more comfortable than a stock guard.
  • Custom-made guards from your dentist are precisely molded to your teeth and mouth, letting you speak and breathe more comfortably.

If you haven’t gotten a mouthguard yet, or your old high school guard was retired years ago, talk to Dr. Jeffery Spahr and Dr. Janna Spahr about a custom guard.  While the over-the-counter options are better than going unprotected, a custom mouthguard fits your teeth perfectly—and comfortably!

Get to the Bottom of Winter Sensitivity

That first breath of frosty air might be more alarming than invigorating when tooth pain and sensitivity makes being out in the cold an unpleasant experience. Sensitivity to cold air or warm winter drinks can be an important symptom, caused by a number of dental conditions such as:

  • Cracked teeth
  • Cavities
  • Exposed dentin (the layer of the tooth underneath your enamel)
  • Receding gums
  • Over-vigorous brushing

If the cold weather is keeping you indoors because of oral sensitivity, give us a call.

Even though this can be a very busy time of year, if you’re due for a checkup and cleaning at our Lincoln, NE office, or if you have any concerns about your teeth and gums, make time for your dental health. We want to make sure you’re ready to enjoy every frosty moment of the season!

Eco-Friendly Toothbrushes

October 26th, 2022

When it comes to dental hygiene, “going green” is not the first phrase that comes to mind. But if you are brushing properly, you are also replacing your toothbrush every three to four months as the bristles become frayed and wear down. Sure, that’s a tiny amount of plastic from each of us going to our landfills, yet it adds up to millions of brushes a year nationally. If you are concerned about reducing your carbon footprint while reducing your risk of cavities, there are several new toothbrushes designed to make brushing more eco-friendly.

Biodegradable Toothbrushes

Some brushes claim to be completely compostable. These models generally have heads fitted with boar bristles and handles manufactured from sustainable woods or bamboo. Boar bristles aren’t for everyone. Some users complain of the taste of the bristles, and boar bristles might be harsher than the soft bristles we recommend to protect both enamel and gums. There is also some concern about bacteria growth on organic bristles.

Earth-friendly Handles and Bristles

If you prefer the consistency and texture of regular synthetic bristles, you can still opt for a brush with a handle of sustainable wood or bamboo. You can also select PBA-free bristles, bristles made primarily of castor oil, or bristles that use natural ingredients in combination with synthetics.

Reduce, Reuse, Recycle

If these exotic brushes aren’t for you, there are more conventional choices that will save energy and cut down on waste.

  • Reduce the amount of electricity you use for your electric toothbrush with a model that requires less charging time.
  • Reuse your toothbrush by buying one with a handle made of metal, natural materials or plastic and replace the detachable head every three months.
  • Recycled plastics can be found in the handles of some toothbrushes, and many brushes come in recyclable packaging. Every bit helps!

If you decide to use one of these green products, remember that your dental health is still the primary goal. Be sure the bristles of your brush are soft enough to protect your gums and enamel and can reach all the places you need to brush. The handle should be easy to grip and the head should be a comfortable fit for your mouth. It’s always best to choose products with a seal of acceptance from your local dental association, or talk to us about greener alternatives during your next visit to our Lincoln, NE office. Luckily, there are several workable options to protect the health of your family's teeth while still being mindful of the health of our planet.

Osteoporosis and Dental Health

October 19th, 2022

What do we know about osteoporosis? We may know that this disease makes the bones more brittle and vulnerable. We may know that osteoporosis is the cause of many a broken hip or curved spine as we age. We may even know that, for a number of reasons, women are far more likely to develop this disease. What we may not be aware of is the impact osteoporosis can have on our dental health.

“Osteoporosis” means “porous bones.” It is a disease that makes the bones more likely to fracture or break, as the body’s careful balance of absorbing old bone tissue and replacing it with new healthy bone tissue is disrupted. We lose bone tissue faster than we can create new, dense bone tissue. Why is this important for our dental health? Because the fitness of our teeth depends on the fitness of the bones surrounding and securing them in our jaws.

How does osteoporosis affect dental health?

  • Osteoporosis reduces density in the bones and bone tissue that hold our teeth in place. Studies have shown that women with osteoporosis have significantly more tooth loss than women without the disease.
  • Periodontitis, or gum disease, can also cause deterioration in the bone surrounding the teeth. This is a time to be proactive with gum health to avoid infections and further bone loss.
  • Denture wearers may find that their dentures no longer fit properly due to changes in bone structure. Bone loss needs to be addressed promptly to avoid having to replace dentures.
  • Rarely, bone-strengthening medications for osteoporosis can lead to serious jaw problems after dental procedures that involve the jawbone (such as extractions). Always tell us any medications you are taking before we schedule any dental treatment.

Unfortunately, osteoporosis often has no symptoms at all—until the first bone fracture. Checking our bone density is important as we age, and one way of discovering changes in bone density is through your regular dental checkups at our Lincoln, NE office. We can pinpoint changes in your X-rays through the years and will recommend that you see your physician if there is any indication of bone loss. If you have already been diagnosed with the disease, we have ideas to help maintain the health of your teeth and bones.

Many factors can increase your chance of developing osteoporosis. Age, illness, personal habits, medications, diet, genetics—any number of conditions can affect our bone health. Talk to us about osteoporosis. Dr. Jeffery Spahr and Dr. Janna Spahr would like to work with you to provide prevention and treatment to keep your teeth and bones strong and healthy for a lifetime of beautiful smiles. And that’s certainly good to know!
