Just What Is a Cavity, Anyway?

November 10th, 2021

The grownups in your life encourage you to brush and floss, eat healthy foods, and visit us in the dental office for exams and cleanings. Why? Because we all want to help you prevent cavities.

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 that 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 that 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, which 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 that 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 that 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 that 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 Florence 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. We even have special coatings called sealants that can protect your teeth from plaque.

  • 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 Dr. Robin E. Lents 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!

The Intriguing History of Halloween

October 27th, 2021

Halloween is fast approaching, and Dr. Robin E. Lents wanted to be sure to wish our patients a happy day, no matter how you might celebrate this holiday. The Halloween that is familiar to most people today bears little resemblance to the original Halloween; back in the "old days" it wasn't even called Halloween!

Festival of the Dead

Halloween started out as a Celtic festival of the dead that honored departed loved ones and signified a change in the cycle of the seasons. The Celtic people viewed Halloween, then called "Samhain," as a very special day – almost like our New Years day in fact, as their new calendar year began on November 1st. Samhain was the last day of autumn, so it was the time to harvest the last of the season's crops, store food away for winter, and situate livestock comfortably for the upcoming cold weather. The Celts believed that during this day, the last day of winter, the veil between this world and the spirit world is the thinnest, and that the living could communicate with departed loved ones most effectively on Samhain due to this.

Modern Halloween

Halloween as we know it today started because Christian missionaries were working to convert the Celtic people to Christianity. The Celts believed in religious concepts that were not supported by the Christian church, and these practices, which stemmed from Druidism, were perceived by the Christian church as being "devil worship" and dangerous.

When Pope Gregory the First instructed his missionaries to work at converting the Pagan people, he told them to try to incorporate some of the Pagan practices into Christian practices in a limited way. This meant that November 1st became "All Saints Day," which allowed Pagan people to still celebrate a beloved holiday without violating Christian beliefs.

Today, Halloween has evolved into a day devoted purely to fun, candy, and kids. What a change from its origins! We encourage all of our patients to have fun during the holiday, but be safe with the treats. Consider giving apples or fruit roll-ups to the kids instead of candy that is potentially damaging to the teeth and gums.

Remind kids to limit their candy and brush after eating it! Sweets can cause major tooth decay and aggrivate gum disease, so to avoid extra visits to our Florence office, make your Halloween a safe one!

Easing the Teething Blues

October 20th, 2021

Every moment of your baby’s first year of life is precious, since every day your child grows a little, develops new skills, and discovers new things. Most of it is wonderful, but parents don’t like to see their babies in pain. That’s why teething can be such a hard experience. However, you can take steps to make it easier for you and your baby.

What to Expect

Most babies begin teething around the age of six months, when the lower central incisors start to appear. Shortly after this time, the upper central incisors poke through, followed by the lateral incisors, first molars, canines, and second molars. Unfortunately, you’ll probably know that your baby is teething not because you see these teeth come in, but because your baby will be in discomfort. These are some of the signs to watch for when you’re expecting your baby to begin teething.

  • Tender and sore gums
  • More drooling than before
  • Being crankier than usual
  • Chewing on hard objects

What You Can Do

As a parent, you want to do everything you can to make your child more comfortable. These are some approaches that Dr. Robin E. Lents and our team recommend:

  • Take a clean moistened wash cloth or use your own washed finger to rub your baby’s gums and provide relief due to the pressure.
  • Provide a firm rubber teething ring for your baby to use, but don't use the type that is filled with liquid.
  • Use a bottle. A bottle filled with cold water can be soothing. Don’t give your baby formula, milk, or juice constantly because the sugar can cause tooth decay.
  • Medications can help for extreme crankiness. Infant Tylenol is an example, but it’s best to check with your pediatrician before giving your baby medications.

You might also want to take special care to dry the drool. It’s not just to keep yourself and your baby dry. Keeping your baby’s skin dry can help prevent irritation.

When to Visit Us

Once your child’s first tooth comes in, it’s time to start thinking your baby’s first trip to our Florence office. The American Dental Association suggests that you bring your child to the dentist within six months of the appearance of the first tooth, or at about one year of age. Dr. Robin E. Lents can do a quick check for tooth decay, and we’ll make sure you know how to take care of your child’s new teeth.

Dental Sealants for Baby Teeth?

October 13th, 2021

Perhaps you’ve heard your friends talking about dental sealants, and how well they prevent cavities. And as soon as your child’s permanent molars come in, you absolutely plan to make an appointment at our Florence office for this treatment. But should you also be concerned with your child’s baby teeth? Could they benefit from sealants too?

Even though those beautiful baby teeth are going to be replaced with permanent teeth, they should still be protected. Primary teeth help with speech development, enable your child to develop proper chewing and eating habits, and serve as place holders so that permanent teeth can erupt in the correct place. That’s why you’ve been so careful to help your child brush and floss twice daily, and make regular visits to our office for exams and cleanings.

But some teeth are just harder to keep clean with regular brushing than others. Primary molars, just like permanent ones, have depressions and grooves on the chewing surfaces. These grooves collect bacteria and food particles that are hard for bristles to reach, providing a perfect opportunity for cavities to develop in those little molars.

Cavities are not the only problem which can affect primary teeth. Because baby teeth have thinner layers of protective enamel, a cavity can actually reach the pulp (the center of the tooth) more quickly, leading to pain and potential infection.

While baby teeth can be treated, with fillings, restorations, and even stainless steel crowns, preventing tooth decay is always our first, best choice. And dental sealants are recommended by the American Academy of Pediatric Dentistry and the American Dental Association as one of the most effective ways to prevent cavities in both baby teeth and adult teeth.

Dental sealants are safe and effective.  Sealants are thin coatings (usually a plastic resin or other dental material) that cover a molar’s grooves and depressions, making it impossible for bacteria and food particles to collect there. Applying them is a simple, pain-free process.

Each tooth will be examined first. If we find any signs of decay starting, we will gently treat that area before applying the sealant. After the tooth is cleaned and dried, an etching solution will be brushed on to the surface area being sealed. This etching roughens the surface so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light.

That’s all there is to it! Sealants typically last from three to five years, and some last even longer. Keep up your regular careful brushing and flossing, and we will monitor the condition of the sealants at each exam.

Talk to Dr. Robin E. Lents about dental sealants. We’ll let you know if your child can benefit from the procedure even before those baby teeth give way to permanent ones. It’s never too early to prevent tooth decay!
