Part of every dental checkup is making sure all of your teeth are strong and healthy. Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes 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, Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes 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 Chicago 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!

In a perfect world, we would all jump out of bed ready to greet the day with a big smile and a toothbrush close at hand to clean our teeth immediately. But if you can’t even find your toothbrush before you’ve had your first cup of coffee, does it really make a difference if you brush and floss after breakfast? Perhaps! Let’s talk biology.

Normal saliva production during the day benefits our teeth and mouths in surprising ways. Saliva washes away food particles to keep our teeth cleaner. It contains cells which combat bacteria and infection. It even provides proteins and minerals to help protect our teeth from decay. But saliva production slows dramatically as we sleep, and the amount of bacteria in our mouths increases. While one of the nasty—and obvious—side effects of bacterial growth is morning breath, there is an invisible effect, which is more harmful. Bacteria in plaque convert sugar and carbohydrates into acids which attack our gums and enamel and can lead to both gingivitis and cavities.

• If You Brush Before Breakfast

Brushing and flossing first thing in the morning removes the plaque that has built up during the night and takes care of many of the bacteria who are ready to enjoy the sugar and carbs in that breakfast with you. If you brush before eating breakfast, rinse your mouth with water after your meal, floss if needed, and you are good to go.

• If You Choose to Brush After Breakfast

But if you decide that doughnut simply can’t wait, you should ideally postpone brushing for 20-30 minutes after your meal. Of course, these are minutes in which bacteria can make use of those new sugars and carbohydrates. So why shouldn’t you brush immediately after eating? Many foods and beverages, especially acidic ones such as grapefruit and orange juice, can weaken the surface of your teeth. If you rinse with water after eating and wait at least 20-30 minutes before brushing, your enamel will be “remineralized” (another benefit of saliva) and ready for cleaning.

No matter if you take a “seize the day” approach and brush first thing in the morning, or a “seize the doughnut” approach and brush soon after eating, the important word here is “brushing.” Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our Chicago team are happy to make suggestions as to the best morning routine for you. One thing is certain: if you give your teeth and gums two minutes of careful brushing and flossing in the morning, you can’t help but start your day off right!

Hand-foot-and-mouth disease, or HFMD, is a type of contagious viral illness that causes a rash in the mouth and on the hands and feet of infants and young children, and, while rare, adults. Characterized by sores in the mouth and a rash on the hands and feet, hand-foot-and-mouth disease is most commonly caused by a coxsackievirus, a bacterium that lives in the human digestive tract. HFMD can spread from person to person, typically via unwashed hands.

What are the symptoms of HFMD?

Symptoms of HFMD usually begin with a fever, sore throat, poor appetite, or general malaise. A couple of days after the fever starts, kids may develop painful sores in the mouth. A skin rash characterized by red spots may also develop, usually on the palms of your child’s hands and soles of their feet. It’s important to note some children may only experience a rash while others may only have mouth sores.

Is HFMD serious? Should we be concerned?

Usually not. Nearly all children infected recover anywhere between seven to ten days without medical treatment. Rarely, however, a child can develop viral meningitis and may need to be hospitalized. Other rare complications of HFMD can include encephalitis (brain inflammation), which can be fatal.

How can my child prevent HFMD?

There is no known vaccine to defend your child against HFMD. However, the risk of your child contracting the disease can be reduced by:

• Making sure your child washes his or her hands often
• Thoroughly cleaning objects and surfaces (these include doorknobs and toys)
• Making sure your child avoids close contact with those who are infected

If you were to put your toothbrush bristles under a high-powered microscope, what you would see might give you nightmares: millions of bacteria, busily crawling up and down your toothbrush bristles, consuming proteins that came from your mouth, and still clinging to the bristles even after you’ve rinsed them with water.

Rinsing your toothbrush after brushing removes some of those ferociously hungry bacteria, but not all. The American Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The ADA also states that unless a toothbrush is sterilized before being packaged, it’s going to come with bacteria – free of charge!

Germs and Frayed Bristles: the Demise of a Toothbrush

Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our staff recommend that you toss your old toothbrush in the trash and purchase a new one every three months. Children tend to bite on their toothbrushes, which makes the bristles degrade and fray faster. Chances are kids may need to have their toothbrushes changed more frequently.

Where do they hide?

Bacteria are tenacious little germs that head for those concealed areas between toothbrush bristles. They are highly adaptable and exist in every type of extreme environment. Some people actually go so far as to put their toothbrush in a microwave for a few seconds to kill germs, but this doesn't always work either. In fact, you may only end up with a toothbrush that’s as bendable as a Gumby doll – and still covered with germs.

Feed a Cold, Starve a Fever, and Get Rid of Your Toothbrush

When you have a head cold, your mouth is teeming with bacteria gleefully roaming around, and gobbling mucus and dead skin cells. If you brush your teeth while suffering a sinus condition, the brush will act like a magnet for ravenous bacteria. Use your old toothbrush while you are sick, but as soon as you feel better, throw it away and get a new one. Otherwise you could possibly re-infect yourself with the same cold germs!
