Just What Is a Cavity, Anyway?

January 8th, 2025

So you might be wondering, just what are cavities? How do we get them? What do they do to our teeth? How can we prevent them? Let’s talk!

Our teeth need to be strong to bite and chew. That’s why they are protected by a coating called enamel, which is made up of very hard minerals. Enamel is the strongest part of our bodies—stronger even than our bones. But this doesn’t mean nothing can hurt it! And cavities, also called tooth decay, are one of the most common dangers facing our enamel.

So, what are cavities?

A cavity is a hole in your tooth enamel. If your tooth is not cleaned and repaired when a cavity is small, this hole can grow bigger until tooth decay reaches the inside of your tooth. Enamel doesn’t heal when it’s damaged, so you need to see a dentist to make your tooth healthy again.

How do we get cavities?

Bacteria are tiny little germs. Many kinds of bacteria live in our bodies, and some of them are quite helpful. The bacteria which cause cavities are not. These unhelpful bacteria join with our saliva and very small pieces of the food we’ve chewed to make a sticky film called plaque.

Like other living things, the bacteria in plaque need food. They get that food from the foods we eat, especially sugars and starches. As they eat, they change these sugars and starches into acids, and these acids attack the minerals which keep enamel hard and strong.

Because plaque sticks to our teeth, bacterial acids are able to make weak spots in enamel if the plaque isn’t brushed away. If you see a white spot on your tooth, that could mean that your enamel is losing minerals, and getting weaker.

What do cavities do to our teeth?

Over time, weak spots can grow bigger until there’s a hole in the enamel surface. If the cavity in your enamel is small, you might not notice it at first. But cavities can become wider and deeper, and even break through enamel to reach the inside of your tooth.

The inside of each tooth holds pulp, the part of your tooth which keeps it healthy. If tooth decay spreads to the pulp, it can cause more damage and infection, so it’s important to treat a cavity right away.

Dark spots on your enamel, a toothache, pain when you drink something hot or cold or when you bite down—these can be clues that you have a cavity, and you should visit us for an exam.

How can you prevent cavities?

Even better than treating a cavity is preventing one. Let’s make a list of some helpful do’s and don’ts for cavity prevention:

  • Do: Feed yourself foods which are good for you.

Foods like milk and cheese and many dark green vegetables have lots of calcium and vitamin D to help keep your enamel strong.

  • Don’t: Feed bacteria foods which are good for them.

Sugar and simple starches like potato chips are the kinds of foods bacteria like best, because they are easy to break down. This means more acids to attack your enamel.

This doesn’t mean you should never enjoy a treat! But eating lots of starchy snacks and drinking sugary sodas means more plaque, and more plaque can mean more cavities. If you’re eating something starchy or sweet, it’s a good idea to brush or rinse afterward.

  • Do: Brush at least twice a day, for at least two minutes, with fluoride toothpaste.

This is the best way to get rid of plaque, which builds up every day. And fluoride toothpaste even helps make your enamel stronger.

  • Don’t: Forget to floss.

Flossing takes a while to learn to do well, but it’s very important. Flossing helps prevent cavities between the teeth and near the gums.

  • Do: Visit our Dallas dental office for exams and cleanings.

Not only will we look for cavities, we’ll let you know the best way to brush and floss so you can get your teeth their cleanest.

  • Don’t: Feel bad if you get a cavity!

Some people are more likely to get cavities than others, even when they brush just right and eat healthy foods. If you have a cavity, we can remove decay and repair your tooth with a filling.

And one last thing to do: talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani if you have any questions about the best ways to protect your teeth from cavities. We have lots of suggestions to help you take care of your healthy, beautiful smile!

Protect Your Baby from Early Childhood Caries

January 1st, 2025

Your baby’s first smiles are precious—and you want to make sure those precious smiles are as healthy as they are beautiful. One of the most important ways to protect your child’s dental health is by preventing early childhood caries, or cavities.

You might be thinking, “Tooth decay? Babies?” Yes, babies and toddlers can get cavities, too. Studies suggest that over a quarter of children between the ages of two and five already have some form of tooth decay.

The bacteria that cause tooth decay are passed from person to person. Cavity-causing bacteria use the sugar and starches in our diets to produce acids—acids which attack the tooth’s enamel, breaking down its hard mineral structure until cavities form. Because baby teeth have thinner enamel coatings than adult teeth, they are especially vulnerable to tooth decay.

You can start your child on the path to a lifetime of healthy smiles by being proactive about cavity prevention during your baby’s first 12 months.

  • Don’t Share Bacteria

Because cavity-causing oral bacteria are transmitted from person to person, doctors and dentists suggest that you don’t share a spoon with your baby, or put a pacifier in your mouth to clean it. And it’s a good idea to rinse toys used by other children with clean water before giving them to your child.

  • Keep Bottles Out of Bed

Babies generally need a feeding before bedtime to ensure that they get all the nutrition their growing bodies need. But when a young child sleeps with a bottle, liquids pool in the mouth, exposing tiny teeth to these liquids throughout the night and preventing the natural flow of saliva from washing food particles away.

Bring your child’s happy day to a close with a lullaby, a bedtime story, a good night kiss, or whatever makes your baby feel comforted and loved—and take the bottle with you when you tiptoe out of the room.

  • Avoid Sugary Drinks

How do parents make sure their babies get the nutrition they need without giving cavity-causing bacteria the fuel they need? With a healthy diet. Breast milk and formula have healthy nutrients, carbs, and sugars which are necessary for baby’s growth and development. Sugar water, sweet juices, and sodas—don’t.

Added sugars provide a feast for cavity-causing bacteria, and the more your child is exposed to them throughout the day, the greater the risk of tooth decay. Talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani for the healthiest drinks for your baby’s bottle or sippy cup.

  • Clean Baby’s Teeth and Gums

Dentists recommend cleaning your baby’s gums even before teeth begin to arrive. After washing your hands, using a clean, damp, soft cloth or gauze pad to gently wipe the gum surfaces to remove bacteria and food.

As soon as the first tooth appears, it’s time to start gentle brushing. Use a baby-sized toothbrush to gently clean the erupting teeth once in the morning and once after the last feeding of the day. And as soon as two baby teeth touch, it’s time to talk about flossing.

Not sure about baby-friendly tooth care products, toothpastes, and techniques? Talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani! Learn about cleaning little gums, baby-size brushes, when to begin using fluoride toothpaste and how much toothpaste to use, when to brush, and when to start flossing.

  • Establish a Dental Home for Your Child

The ideal time for your child’s first visit to our Dallas office is sometime between the appearance of your child’s first tooth and your child’s first birthday. It’s a gentle way to introduce your baby to the dental team who will be caring for those little smiles for many years to come.

During that first visit, your child’s dentist will check tooth and jaw development. There will be a child-friendly examination to look for plaque buildup or any signs of early decay, such as white spots on tooth enamel. You can talk about any concerns you might have and learn the best ways to prevent tooth decay with proactive dental care for healthy teeth and gums.

Why are we so concerned about baby teeth? Decayed teeth can cause pain and self-consciousness. And more, those tiny teeth have big responsibilities. Baby teeth influence your child’s speech development. They promote healthy eating and chewing habits. Baby teeth serve as placeholders to make sure that your child’s adult teeth will be able to erupt just where they should.

Your baby’s first smiles are precious. And when you’re proactive with early dental care, you’re preparing your child for a lifetime of healthy smiles.

Let's Talk About Your Roots!

December 26th, 2024

You’ve learned a lot from your dentist and your family about how to take care of your teeth. You brush and floss, you wear a mouthguard when you’re active, and you have regular checkups and cleanings at our Dallas office.

And everything you’re doing is wonderful! The smile you see each day in the mirror reflects your hard work.

But what about the part of your smile you can’t see? Let’s take a look beneath the surface, and talk about your roots.

While our teeth look solid from the outside, there’s really a lot going on inside each tooth.

  • The outside of every tooth is covered with a hard protective surface.

Enamel is the hardest material in our bodies, and covers the crown. This is the part of the tooth we can see above our gums.

Our roots are hidden below our gums, and are covered with cementum instead of enamel. Cementum is hard, but it’s not nearly as strong as enamel.

  • Just below a tooth’s enamel and cementum layers, we have dentin.

Dentin is a hard tissue, only a little softer than enamel. Most of our tooth is made of dentin. It surrounds and helps protect the center of the tooth and supports the enamel and cementum on the outside.

  • Inside the center of each tooth, there’s an area called the pulp chamber.

The pulp holds tiny blood vessels and nerves. The blood vessels give the pulp nutrients, and the nerves are the reason that our teeth can feel sensitivity or pain.

Inside the roots, we also find pulp in the root canals. These canals are very small tunnels that run from the pulp chamber down through the root, ending in a tiny hole in the tip of the root. Blood vessels and nerves running through the canals connect the pulp tissue to our bodies’ blood and nervous systems.

Around your roots, there’s a lot going on, too. Smaller teeth like the incisors, our front teeth, usually have only one root. Bigger teeth, like molars, usually have two or three roots. And while you’re busy biting and chewing, what’s holding these roots in place?

  • In your jaws, you have a spot where each tooth fits called a socket. But your tooth roots don’t just sit in the socket. That wouldn’t be very secure!
  • Instead, you have a periodontal ligament surrounding the roots of each tooth. Think of the ligament as groups of tissue fibers that can attach to both the cementum on your root and the bone in your jaw. This double attachment holds your teeth firmly in place. The ligament also helps cushion your teeth from the heavy pressures of chewing.
  • To make things even safer for your roots, your gums help cover them and protect them from bacteria and decay.

As you can see, your body is working hard to protect your roots. What’s the best thing you can do to keep your roots healthy? Do everything you’re already doing!

  • Keep up with your brushing and flossing, and your visits to our office. These good habits protect the teeth and gums you can see, and also the roots that you can’t see.
  • Avoid oral habits that put lots of pressure on your teeth and roots. Biting down on pencils, or ice, or nut shells, or anything not meant for regular eating means you’re risking a cracked tooth.
  • Be safe! Wear your mouthguard when you’re active.
  • Don’t wait to tell your adult if your tooth hurts. Remember, those nerves inside your teeth and roots are there to warn you if your tooth is damaged. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will be able to find out what’s wrong and have you feeling better in no time.

Even though you can’t see them, your roots are one important reason you have your beautiful smile. Taking good care of your teeth now is a way to make sure you have beautiful, healthy smiles for a lifetime!

Healthy Diet, Healthier Gums?

December 18th, 2024

Since gum disease is one of the most common adult diseases, it’s no wonder Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team stress the importance of prevention. Effective brushing and flossing, regular dental appointments for exams and cleanings, and a prompt visit to our Dallas dental office if you notice symptoms of gingivitis (early gum disease) are all important steps to prevent more serious periodontal disease from developing.

One more step you can add to keep your gums their healthiest? Add some gum-healthy foods to your shopping cart! To see how your diet can help prevent gum disease, let’s look at what can cause gum disease.

When plaque builds up between teeth and gums, the bacteria found in plaque cause our gum tissue to become inflamed, swollen, and painful. Left untreated, the gums pull away from the teeth, leaving pockets where bacteria collect and can cause infection.

Prolonged inflammation can lead to the destruction of gum tissue and the connective tissues which anchor our teeth to the alveolar bone in the jaw. Bone loss and even tooth loss can result from untreated gum disease.

Fortunately for us, there are foods that fight inflammation, help with healing, and strengthen and support gum tissue before problems develop. Let’s take a look at some of the valuable gum-healthy nutrients you can add to your diet with some tasty additions to your shopping list:

  • Vitamin A

This vitamin is essential for the health and healing of mucous membranes, including both our gums and the soft membranes in our mouths. Vitamin A is found in animal products such as dairy foods, meat, and liver, or formed in the body from beta-carotenes, found in plant foods such as carrots, peppers, pumpkin, squash, and sweet potatoes.

  • Vitamin C

Vitamin C is one of the so-called “essential nutrients.” These are nutrients that are necessary for our bodies to function properly, and which can only be supplied in our diets. Vitamin C is needed to help our bodies produce collagen, the substance that provides support and structure to our tissues. It also helps us repair tissue, and is a powerful antioxidant. One of the obvious signs that your diet doesn’t contain enough vitamin C is inflamed and bleeding gums.

When we think vitamin C, we instantly picture citrus fruits. Oranges, lemons, limes, grapefruit, and all their cousins are a wonderful source of vitamin C. Looking for a little more variety? You’re in luck! Fruit fans can load up on strawberries, kiwi fruit, mangos, and papayas. Love your veggies? Red peppers, kale, cauliflower, Brussels sprouts, and broccoli contain more vitamin C per serving than a medium orange.

  • Vitamin D

Vitamin D, of course, is essential for dental health because it helps us absorb the calcium that keep teeth (and bones) strong. And there’s more! It helps the body fight infection and reduce inflammation, and studies have suggested a link between vitamin D and better gum health.

Sunlight exposure leads our bodies to produce vitamin D naturally, but it is available in foods as well. Fatty fish, such as salmon, tuna, and herring, are a rich source of the vitamin, as are cod liver oil and egg yolks. It’s also available in foods fortified with vitamin D, such as cow’s milk, soy milk, orange juice, and even many cereals. And while you’re getting the benefit of vitamin D from dairy, you’re also enjoying the proteins they contain, one of which helps neutralize acids in the mouth that can irritate gums. Bonus!

  • Iron

Iron deficiency can lead to a common form of anemia, where your body isn’t creating enough red blood cells to deliver the oxygen your tissues need. (In fact, one of the most noticeable symptoms of anemia is pale gums.) This condition can cause a number of problems, including an immune system that doesn’t work as well as it should. A strong immune system helps us fight infection, including gum disease and other oral infections.

A diet rich in iron can help prevent anemia. We absorb the most iron from foods such as meat, eggs, and fish, but iron is also present in beans, lentils, leafy greens, whole grains, nuts, and prunes if you’re looking for flavorful vegetarian options.

  • Omega-3s

Research has shown a possible relationship between getting the recommended dietary amounts of omega-3s and a lower occurrence of periodontitis. In other studies, omega-3s have shown promise in reducing the periodontal inflammation that can lead to severe gum disease.

Our bodies can’t produce omega-3 fatty acids on their own, but fatty fish such as salmon, tuna, herring, and sardines, a variety of high-fat seeds and nuts, and plant oils contain several different types of omega-3 fatty acids. Some foods are fortified with omega-3s, or your doctor might recommend fish oil (and algae oil for vegetarians) as a supplement.

Speaking of supplements, why not just add vitamin, mineral, and other nutritional supplements to our daily diet? Believe it or not, there can actually be too much of a good thing. Body chemistry requires balance, so talk to your doctor about whether or not supplements are necessary in your particular diet, and just what kinds and how much to take.

Whew! That’s a lot to think about for one shopping cart, but that’s just a small portion of the many foods—and the many vitamins and minerals—you can add to your menu to support oral health in a tasty, effective, and positive way.

After all, when we think about the “do’s and don’ts” of a dental-healthy diet, it’s all too often a collection of “don’ts.” Don’t eat a lot of sugar. Avoid acidic foods and beverages. Cut down on refined carbs. And all of those suggestions are important, because the early stages of gingivitis are often easy to miss.

But let’s not forget the things we can actually do to be proactive with our gum health. Besides good dental hygiene and regular checkups at our Dallas office, eating a well-balanced diet helps keep your gums their healthiest—and while we can do a lot to treat gum disease, the very best treatment of all is prevention!
