Interproximal Cavities: The Inside Story

December 21st, 2022

Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth which sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity which develops on one of those side surfaces of your teeth.

  • Discovering Interproximal Cavities

Clearly, a cavity between the teeth won’t be as obvious as other cavities. How will you know if a dental appointment is in order?

There are typical symptoms which can show up when you have a cavity. Chewing might be painful. You might feel pain or sensitivity when you eat or drink something which is hot, or cold, or sweet. But pain and/or sensitivity aren’t always present, especially when a cavity is just beginning to develop.

Regular exams are important so you can catch small cavities before they become more serious. That’s why, at your regular dental exams, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will always check for any signs of decay on every surface of each tooth, including those places which aren’t easily visible. And that’s why X-rays can be an important tool for locating these tricky cavities.

  • Treating Interproximal Cavities

If Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team finds a cavity between your teeth, there are different treatment options available depending on the size of the cavity:

  • A typical cavity will require a filling. The decay will be removed, and then the area will be cleaned and filled. You’ll probably choose a filling material which can be matched to your enamel color if the restoration will be noticeable.
  • If decay has spread to the pulp chamber inside the tooth, a root canal is often the best treatment option, with a crown applied afterward to protect the tooth.
  • A tooth so decayed or infected that it cannot be saved might require extraction.

Dealing with any weakness in a tooth as quickly as possible is always better than waiting until a more complicated treatment option is needed. Of course, the best treatment is prevention, and, luckily for us, it’s not a complicated process at all.

  • Preventing Interproximal Cavities

In fact, it’s about as basic as it can be—brush and floss effectively. We recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gumline—places where bristles just can’t reach. The next time you get your teeth cleaned at our Dallas office, ask for tips on how to perfect your technique. And, if you have difficulty flossing, ask about alternatives such as water flossers and interproximal brushes.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with us to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

Be Good to Your Gums

December 14th, 2022

You brush and floss thoroughly twice a day. You have regular checkups. Everything seems fine on the periodontal radar. Sometimes, however, even healthy gums can become sensitive and irritated. Is it something you did? Maybe! Here are some common causes of gum irritation and sensitivity that you might not be aware of.

  • Brushing Bravado

One of the most important tools for gum health is one we use at least twice a day—the simple toothbrush. Two minutes at night and two in the morning reduce the bacteria and plaque that lead to serious gum disease, known as periodontitis. And while preventing tooth decay and gum disease are the primary goals of brushing, let’s also protect delicate gum tissue from injuries and irritation caused by too-forceful brushing.

Try using a brush with soft bristles and brushing with short strokes and gentle pressure, especially if you know you have a tendency to be a bit heavy-handed. Massaging rather than scrubbing will clean teeth and gums just fine.

  • Fierce Flossing

Just because we can use dental floss to slice cakes or cookie dough logs doesn’t mean we should apply the same pressure to our gums! While a firm sawing motion seems like the obvious way to clean between teeth and gums, you can actually cause irritation and bleeding that way.

Insert the floss between your teeth carefully, bring it to the gumline, and move the floss with gentle pressure up and down and around the tooth surface. This technique will make sure that you remove food particles and plaque from beneath the gumline without causing your gums any trauma. Ask us about the best flossing techniques—we know them all.

  • Appliance Aches

You know how helpful your braces/retainers/mouth guards/dentures are. You just wish that your helpful appliance was a little less irritating to sensitive gum tissue.

This is a problem that often disappears as you get used to your new appliance. But if pain or irritation persists or gets worse, give us a call. We want to make sure your appliance fits properly, and make any necessary adjustments to ensure your comfort.

  • Peroxide Problems

Most home whitening kits use peroxide-based gels or treated strips to remove surface stains from the teeth. Those same bleaching agents that make enamel whiter can also cause gum sensitivity and irritation. If you use whitening strips or gel trays, be careful to keep the peroxide solution away from gum tissue. But because these systems are one-size-fits-all, that is often easier said than done.

If you have sensitive gums, one solution is a professional office whitening. We’ll check on your gum (and tooth) health first, and monitor and protect your gums throughout the procedure. If you still want to whiten at home, we can create custom trays for you that will provide more complete exposure to the whitening solution for your teeth, and less exposure for your gums, than over-the-counter products.

  • Still Smoking?

Studies have shown a strong link between gum health and smoking and other forms of tobacco use. Smokers are much more likely to suffer from gum disease than non-smokers, and those who have smoked for a long time, or who smoke heavily, have an even higher risk of developing periodontal disease. Some studies suggest that smokers don’t respond as well to treatment as non-smokers.  Unfortunately, it appears that smoking and tobacco use help mask the obvious symptoms of gum disease (redness and bleeding), which could lead smokers to delay getting treatment. If you smoke, talk to us about ways to quit.

We talk a lot about periodontal health because it is so important. Periodontitis can lead to infection, loss of bone around the tooth, and even eventual tooth loss. If you are suffering from any of the signs of gum disease—swelling, redness, bleeding, pain—give our Dallas office a call. Whether it’s as simple as making a few lifestyle changes, or a problem requiring professional dental treatment, being proactive with your dental care is more than good for your gums—it’s good for your health!

Lip Service

December 14th, 2022

When you think of Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani, you naturally think of your teeth. But your dental professional is concerned with more than the teeth, as important as they are. All aspects of your oral health—gums, bite, tongue, mouth—contribute to your well-being. So many elements go into creating your beautiful smile, and your lips? They’re front and center.

  • SPF—BFF

You already know that sunscreen is your best friend when it comes to protecting your skin. But don’t forget your lips when you’re slathering on the sunscreen! Delicate lip tissue is also susceptible to the sun’s damaging UV rays. Use a lip balm or lipstick with an appropriate SPF (Sun Protection Factor) for your skin type, and apply it liberally. Don’t forget to reapply every hour or two, after eating and drinking, and after going in the water. And if you’re protecting your children from the sun’s rays, check with your doctor about using sunscreen on young lips.

  • Healthy Hydrating

Dry, chapped lips are no one’s go-to look. And while moisturizers and balms can help dry lips recover, there’s a simple preventative measure you can take to avoid or reduce dryness.  You know how important water is for our bodies, and it’s essential for hydrating our lips as well. Make sure you drink the recommended amount of water each day for lips (and skin!) that are healthy and hydrated.

Not so healthy liquids? Alcohol. Alcohol is dehydrating, which undoes the benefits of that water you’ve been drinking. More than that, excessive alcohol consumption has been linked to oral cancer, especially when coupled with tobacco use.

  • Toss the Tobacco

All tobacco users have an increased risk for oral cancer. Pipe and cigar smokers are particularly at risk for lip cancers, and smokeless tobacco users have a greater risk of cancers on the inner lip surface. Need another reason to quit? Smoking leads to an increase in lip lines (wrinkles) and a decrease in lip volume.

  • Oral Exams

When you come to our Dallas office for regular checkups, you can also get regular screenings for oral cancer and other oral conditions. While irregularities are often benign, lip cancer is one of the most common forms of oral cancer, and detecting cancerous or precancerous lesions as early as possible is important for treatment. If you have a sore or lump that doesn’t go away, a red or white patch of skin, bleeding or pain, or any other symptom that concerns you, talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani.

Protect yourself from the sun, hydrate, use alcohol in moderation, give up tobacco if you are using it, and see your dentist regularly for examinations. These simple practices are beneficial not only for your expressive lips, but for your overall health and well-being. And feel free to spread the word—healthy habits and preventative care should be on everyone’s lips!

Why Do Molars Seem to Get More Cavities?

December 7th, 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, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani 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 Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani, though! Through regular checkups and cleanings at our Dallas 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!
