Curious About Cavities?

April 8th, 2026

Part of every dental checkup is making sure all of your teeth are strong and healthy. Dr. Irwin Seidman will have you open wide to look at your teeth, use special little mirrors to get a good look around each tooth, and take X-rays to make sure your teeth are healthy both inside and out.

Why does your dentist want to check each tooth so carefully? One big reason is to look for cavities. What are cavities, and why don’t you want them? We have some questions and answers if you’re cavity-curious!

Just What Is a Cavity?

A cavity is a little hole in your tooth caused by tooth decay.

A Hole in My Tooth? How Did It Get There?

Most of the time, we get cavities because of plaque buildup.

Plaque is a sticky film that builds up on our teeth all through the day. It’s mostly made up of saliva (or spit), tiny bits of the food we chew, and germs called bacteria.

The bacteria in plaque use these food particles from our meals for their own food. Part of the way they use that food is to create acids.

Even though our teeth are very strong, acids can make them weaker as they break down the hard enamel on the outside of the tooth. This is the start of tooth decay. As time goes by, and more acids attack our tooth, a weak spot can grow larger and deeper, making a hole in the tooth.

Why Are Cavities Bad for My Teeth?

If a cavity gets too big, it can reach the inside of your tooth. Inside each tooth, we have pulp. Healthy pulp keeps our tooth alive, and it contains nerves which can feel pain. This is why a deep cavity gives you a toothache. If the pulp is damaged, your tooth is in danger.

How Can My Dentist Help?

When you have regular checkups, Dr. Irwin Seidman can find small cavities and treat them before they become big ones. This helps keep your smile healthy and toothache-free!

To start, your dentist will give you medicine to make the area around your tooth numb if you need it. When your tooth is numb, your dentist will clean away all of the decay with special small drills. They can be noisy, but they won’t hurt.

Once all of the decay is gone, your dentist will fill the hole with—a filling! A filling can be made of metal or a material which matches your tooth color.

When your appointment is finished, your tooth will be free from all the bacteria that were hurting it, the hole in your tooth will be filled, and you’ll be able to eat and bite and chew just like you could before. But what’s even better than treating a cavity? Preventing one!

How Can I Prevent Cavities?

There are lots of ways to get a cavity. Sometimes it’s caused by what people do, like eating lots of the foods which cavity-causing bacteria love. Sometimes, a cavity is caused by what people don’t do, like not brushing and flossing enough. And some people get cavities even with careful brushing and a healthy diet, so they might need extra help to protect their teeth.

Here are three very good ways to help stop cavities before they ever start:

  • Don’t Feed the Bacteria!

The bacteria in plaque like sugars and starches because these foods are the easiest for them to use. And when they get more food, they make more acids. Desserts and sodas, soft breads and chips, and sugary cereals—these foods make tasty meals for bacteria and they stick to your teeth. Eating a balanced diet without too many sugary and starchy treats means fewer acids—and fewer cavities!

  • Brush and Floss

Brushing at least twice a day helps get rid of the sticky plaque holding those cavity-causing bacteria. Flossing helps remove plaque where your brush has a hard time reaching, like the spaces between your teeth. Your dentist and hygienist can show you the very best ways to brush and floss to get rid of the most plaque.

  • Cavity-Fighting Treatments

Your dentist can also treat your teeth to help keep cavities from ever starting, especially if you’re someone who gets cavities more easily. Professional cleanings at our Palatine, IL dental office and dental sealants are two ways to protect teeth from plaque and bacteria. Your dentist will have some ideas just for you.

Together, you and your dentist make a powerful cavity-fighting team. If you have any questions about keeping your teeth their healthiest, your dentist has the answers!

Preventing Toddler Tooth Decay

April 1st, 2026

You do everything you can to protect your toddler with safeguards large and small. Installing that complicated car seat. Figuring out which sunscreen is best for delicate skin. Spending weeks childproofing your home. But all the work protecting your child is more than worth it because the rewards are so great. And one more everyday precaution that brings great rewards is protecting your toddler from tooth decay.

  • Start Early

The time to start your baby’s dental care is even before that first tooth arrives. Carefully wiping the gums with a clean, damp cloth after feeding gets your child used to the idea of brushing and removes bacteria that might irritate the gums as the teeth begin to erupt. As soon as those teeth arrive, gentle brushing with soft bristles will keep bacteria and plaque from causing tooth decay and gingivitis. We can recommend toothpastes formulated especially for toddlers and suggest the best ways to brush.

  • Mind The Menu

We know that sugary foods aren’t healthy for your toddler’s teeth. Bacteria in the mouth feeds on sugar, and a sugar-heavy diet results in more of the bacteria and plaque which cause cavities. But sugar is not the only food that is not tooth-friendly. For example, foods like citrus fruits and juices can also be a problem. Acidic foods can actually weaken enamel after eating and leave teeth more vulnerable to cavity-causing bacteria and plaque. We have suggestions for tooth-healthy snacks and the best times to brush after eating if you and your child indulge in a treat.

  • Don’t Misuse Bottles & Sippy Cups

Your toddler might still use a bottle at night or a sippy cup throughout the day. Juices and even milk contain sugar that increases the risk of cavities, and if your child goes to sleep with a bottle or cup, these liquids pool in the mouth overnight allowing bacteria to flourish.  If your toddler wants a drink at night or between meals, water is a much better option.

Those tiny teeth are important for so many reasons. They enable children to bite and chew efficiently, to pronounce sounds properly for speech development, and to save space for adult teeth so they erupt in the right place. Dr. Irwin Seidman and our team recommend that your child visit our Palatine, IL office after the first tooth comes in, and always by the first birthday. We will make sure your toddler’s teeth are developing as they should be and suggest ways to keep them cavity-free. Your toddler’s healthy, beautiful smile is a reward worth protecting!

Gum Disease and Your Child

At Palatine Pediatric Dentistry, we know that unfortunately, gum disease can exist in your child’s mouth without you even knowing. In fact, your child may be suffering from the beginning stages of periodontal (gum) disease without noticing any pain or discomfort.

  • Gums that are red or swollen
  • Gums that feel tender
  • Gums that bleed easily during brushing or flossing

  • Loose teeth
  • Any change in the way teeth come together in the biting position

My child has canker sores! How can I help?

March 18th, 2026

According to the American Association of Pediatric Density, roughly one in five children suffers from canker sores. Canker sores are small sores that appear inside the cheeks, on the lips, on the surface of the gums, and under the tongue.

Even though, canker sores are not contagious, they do tend to run in families. There are several reasons your child may be suffering from canker sores including:

  • Children who have Vitamin B12, iron, and folic acid deficiencies tend to get canker sores more often than children who have normal levels of these vitamins and minerals.
  • Children who suffer from food allergies are also at a higher risk for developing canker sores. It’s difficult to determine what your child may be allergic to. If you feel strongly that the canker sores are related to an allergy, then a visit to an allergist is highly recommended.
  • Biting their lip or cheek can also result in a canker sore.
  • Any injury to mouth, where the skin breaks can cause a canker sore.
  • Brushing their teeth too hard can also be a problem.
  • Your child may be sensitive to an ingredient in their toothpaste. Try switching toothpastes and see if it makes a difference.
  • Emotional disturbances and stress are also factors to consider.

If your child has frequent canker sores a visit to our Palatine, IL office will be beneficial. Canker sores are painful and usually last about 14 days. Dr. Irwin Seidman may recommend one or a few of the following treatment options:

  • Avoid food that is acidic, salty, and spicy.
  • A toothbrush with soft bristles may be helpful.
  • Avoid mouthwash and toothpaste that contain SLS.
  • Do not feed your child foods that they may be allergic to.

Canker Sore Remedies

  • Eating yogurt that contains Acidophilus will relieve the pain and help the canker sore heal faster.
  • Put one teaspoon of baking soda in an eight-ounce glass of lukewarm water. Have your child gargle and swish it around his or her mouth several times a day. Not only does this remedy relieve the pain, the canker sore could be gone in as little as 24 hours.
  • Place a wet tea bag on the sore and hold it there for a few minutes several times a day. This remedy will help with the pain and quickly heal the sore.
  • Camphor, Benzocaine, Lidocaine, and Orajel are over-the-counter medications that can help.

If you have questions about your child’s canker sore, contact Dr. Irwin Seidman to schedule an appointment.
