Just What Is a Cavity, Anyway?

April 23rd, 2025

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 Vorhees 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 Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi 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!

Make Every Day Earth Day

April 16th, 2025

Earth Day began in 1970 as an event to raise awareness of our environment. What began as a single day in April is now recognized around the world to bring attention and education to global environmental issues. Conserving our natural resources, reducing water and air pollution, and developing green technologies are all ways in which we can improve the environment around us.

Reduce, Recycle, and Reuse

One of the easiest ways to participate in Earth Day is by simply reducing the amount of refuse that ends up in landfills. Many communities have recycling programs for paper, plastic, and metal refuse. By keeping recyclable items out of landfills, we reduce the need for new disposal space and the amount of energy needed for burning refuse. Recycling products also helps conserve the resources that are used in making new products.

You can save money by reducing your consumption of many everyday products. Single disposable water bottles can be recycled but they are costly. By using filtered faucet water, you can conserve your financial resources. Disposable paper towels can also be wasteful. Consider reusable cleaning rags for the majority of your chores.

Reusing items saves both the environment and your finances. A large number of products can be re-purposed to create a new item. Old furniture can be remade into a new piece. Old clothing can be used for craft items. If you are not able to find ways to reuse your old items, donate them to a charity. Remember to continue your positive environmental steps on a daily basis.

Other things you can do to improve the environment

Everyone, young or old, can find ways to participate in improving the environment. Some ideas include:

  • Planting trees
  • Picking up litter
  • Reducing energy consumption
  • Walking, bicycling, or carpooling to work or school
  • Disposing of hazardous waste properly
  • Using rain barrels to conserve water for plants

Earth Day is designed to appreciate and celebrate the health of the earth. Keeping the earth healthy is important, but keeping your mouth healthy is important, too. Healthy teeth and gums contribute to your overall health and well-being, so remember to call our team at Pasternack Pediatric Dental to schedule an appointment. Have a happy and healthy Earth Day, from Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi!

Avoid Brushing After Every Single Meal!

April 9th, 2025

Here is some surprising yet worthwhile advice you might be hearing for the first time: Brushing can be incredibly bad for your child’s teeth if done right after eating certain foods.

Enamel is an extremely hard mineral on the exterior of each tooth. It’s actually the hardest substance in the human body: It’s even stronger than bones! Its only weakness is that acids in the food we eat can easily destroy enamel.

Healthy teeth thrive in an environment that has the proper pH balance. That ensures the mouth doesn’t start the process of demineralization—the process when alkaline turns into acid, which attacks and softens the enamel on the surface of your child’s teeth. Pores and fissures form, and that’s when the harmful bacteria go to work.

A mouth’s pH level fluctuates depending on what is eaten throughout the day. Examples of the most common highly acidic foods include citrus fruits, soda, and sugary foods. Highly acidic foods tip the balance of pH in the mouth from a healthy alkaline to a dangerous acid.

Can brushing your child’s teeth immediately after a meal lead to even more damage? The answer is yes!

Eating highly acidic foods causes your child’s teeth to be more susceptible. If your child brushes when the teeth have been weakened by acids, even more destruction can happen to the enamel. Your child’s toothbrush bristles will actually wear away some of the enamel. So it’s healthier for your child to wait at least an hour after eating or snacking to brush.

Good preventive measures to take instead of brushing after your child eats include:

  • Rinsing or drinking water
  • Chewing sugarless gum
  • Consuming dairy or non-acidic foods to conclude a meal

These practices help produce saliva, which in turn restores a healthy pH level in your child’s mouth and coats the teeth with minerals they need.

Once your child’s mouth is restored to a healthy pH level, he or she may brush normally. Keep in mind that acidic foods can weaken the enamel on the teeth and take the right measures to prevent spiking pH levels.

Still have questions? Call our Vorhees office and schedule an appointment for your child with Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi.

Should Children Use Whitening Products?

April 2nd, 2025

As adults, we often wish our teeth could be as white as they were when we were small children. Baby teeth have thinner and whiter enamel than adult teeth, and those brilliant smiles are a result! But occasionally, you may be surprised to discover some staining or discoloration on those lovely first teeth. You might be tempted to apply a whitening product to your child’s teeth, but, please—read on!

Causes of Staining

  • Improper Brushing—Often, a loss of tooth whiteness means that plaque has built up on the tooth surface. Careful brushing is needed to remove bacteria and plaque, and if your child isn’t brushing at least twice a day for two minutes, discoloration can be the result.
  • Medications—When given in liquid form, or when added to formula or food, iron supplements can cause dark grey staining on the teeth. Medications taken by a mother while pregnant or breast feeding, such as tetracycline, can also lead to discoloration.
  • Injury—If a tooth suffers a serious injury, the tooth can darken because of changes inside the enamel.
  • Health conditions—Certain health problems can cause tooth discoloration, or sometimes children are born with weaker enamel that is more likely to stain.

If you have noticed any staining on your child’s primary teeth, call our Vorhees office. Simple stains can often be removed with better brushing techniques, and we can clean other surface stains in the office. Staining caused by an injury or a health condition is something we can discuss in detail with you. We can even use some professional whitening methods if those are indicated.

Why not just buy a home whitening kit for your child? There are several important reasons to leave these products on the shelf while your child is young.

  • Whitening kits are designed for adults. They have been tested for adult teeth in adult trials. Check the box for age appropriate use. Most products are not recommended for pre-teen children.
  • Remember that thinner enamel we mentioned earlier? Add to that the delicate skin of young children, and it’s sensible to be cautious about using a bleaching agent that can cause mouth and tooth sensitivity even in adults.
  • There is no body of evidence available as to the short and long term effects of using these products on children.

If you are concerned about the brightness of your child’s smile, please talk to Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi. We can recommend better ways to brush at home, clean your child’s teeth in the office, or suggest professional methods of whitening if there are physical or psychological reasons that it would be valuable. But while your child is young, those off-the-shelf whitening products can wait a few more years.
