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 Michigan Center, MI 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 Dr. Timm 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!

Our pets are a valued part of the family, but dogs and cats are not regularly known for their minty-fresh breath. Did you know that bad breath can be a sign of a more serious dental problem for your furry companion?

If you live with a pet or two, you’ll want to brush up on your animal dental knowledge and make sure everyone’s teeth stay healthy.

Proper dental care is essential to a pet’s overall well-being. About 80 percent of dogs and 70 percent of cats suffer from periodontal disease after the age of three.

Not only is this unhealthy for their mouth, it can lead to more serious health problems, including organ damage and heart failure. Toxins from periodontal disease seep into your pet’s bloodstream and have the potential to cause fatal organ damage.

Your veterinarian will check your pet’s teeth at an annual or six-month examination, but here are a few signs of periodontal disease you should watch for at home:

• Yellow/brown tartar
• Foul breath
• Red, inflamed, or bleeding gums
• Excessive drooling
• Pawing at the mouth or rubbing one’s jaw against objects
• Difficulty chewing

Aside from regular checkups at the vet, the best thing you can do for your pet is brush its teeth daily. Bacteria can recolonize onto the surface of teeth within 24 to 36 hours, so it’s essential to remove plaque before it turns into tartar. Ask your vet for a recommended toothbrush and pet toothpaste.

Dental hygiene chews can also help to reduce the effects of gingivitis, but some chews can actually make your pet’s oral health worse. Treats such as cow hooves, pig’s ears, and animal bones can damage teeth and cause other problems if ingested. Your vet can help you choose items that are healthiest for your pet.

Your dog’s favorite toys may also pose a threat to their oral health. Abrasive toys such as the popular green tennis balls can create wear and tear on the surface of pets’ teeth.

As with your own teeth, your dog or cat’s oral health plays a large role in its overall health. Remember to schedule regular checkups and ask your veterinarian for more tips on how to care for your pet’s teeth most effectively.

Not many people look forward to going to the dentist, especially if you already know that you need dental work done. A small amount of anxiety is one thing, but dental phobia, or odontophobia, is something else entirely. It is an irrational fear of going to the dentist. If you have it, you might be unable to force yourself to go to the dentist, even if you are suffering from bad tooth pain. The effects of dental phobia can be serious, but there are ways to overcome your fear of the dentist to help you achieve and maintain good oral health.

Causes of Dental Phobia

You can develop dental phobia for a variety of reasons, including the following.

• Fear of pain, which you might acquire based on others’ horror stories of their trips to the dentist.
• Fear of needles, such as those used to provide anesthesia.
• A previous bad experience, when something went wrong and pain was intolerable.
• Lack of control from not knowing what is happening or how uncomfortable a procedure might be.

Consequences of Dental Phobia

Avoiding the dentist can have long-term consequences. When caught early, tooth decay is easily stopped with a minor filling. If you let the decay go, you can end up losing your tooth and have chronic pain. A dentist can also check for early signs of gum disease, which, if left untreated, could lead to losing one or more teeth.

Even if you do not have a particular problem, going to a dentist for regular cleanings is a good idea because the hygienist can point out where you need to brush better and remove the plaque from your teeth.

Getting Over Fear of the Dentist

Most patients with dental phobia can get over their condition. These are some approaches that Dr. Timm and our team recommend:

• Explain each step of the process
• Let you know that you can stop the procedure at any time
• Encourage you to come with a family member or friend
• Help you with deep breathing techniques

You’re busy getting ready for your day, and of course you’re starting your day off right by looking after your dental health. A two-minute brushing, some careful flossing, and—wait, is that a white spot on your tooth?

If your mirror reveals a patch of white on your enamel, it could be a symptom of early tooth decay.  Does this mean a cavity is necessarily in your future? Perhaps not, if you act promptly to reverse the damage!

Cavities, after all, don’t suddenly appear in our mouths. Tooth decay is a process, and it begins with a weak area in the enamel that often appears as a white spot on the tooth. These weak spots are known as “incipient cavities,” because they can easily become cavities if left untreated.

Why do these weak spots occur? And how can we repair them? Let’s look at some tooth science.

• Demineralization

Your tooth enamel is one of the marvels of the human body. Enamel is mostly made of calcium and phosphate ions, minerals which combine to form hydroxyapatite crystals. These crystals create a substance so strong that tooth enamel is the hardest part of the body—harder even than bones.

But it’s not indestructible! If you don’t care for your teeth with regular brushing and flossing, you’re leaving your enamel open to attack.

The bacteria in plaque convert the nutrients they get from the food we eat—especially sugars—into acids. These acids strip away the calcium and phosphate minerals which are the building blocks of our enamel, weakening the surface of the tooth.

Over time, these weak spots get bigger and deeper as bacteria and acids continue to attack the tooth surface. Eventually, cavities form, damaging the enamel surface, and, over time, even reaching into the dentin and the pulp inside the tooth. Once a cavity has formed, you need dental treatment to clean away the decay and repair the tooth structure.

The good news is that, when caught early, it’s possible to rebuild a weak spot in the tooth enamel before a cavity can fully develop.

• Remineralization

While acids strip minerals from your enamel, your body is also replacing those lost minerals all throughout the day. How does this balancing act take place? With the help of saliva.

The very minerals which acids strip from your enamel are found in saliva. Saliva bathes your teeth with calcium and phosphate ions which, in turn, bond with your enamel to rebuild and restore enamel strength. When missing minerals are replaced like this, it’s called remineralization.

But this careful balance of demineralization/remineralization can become upset. If you neglect brushing and flossing, for example, plaque buildup will increase the amount of acids your teeth are exposed to. This means that your body won’t be able to replace the minerals as quickly as they are stripped away, and the result is a white patch on your tooth where the enamel has lost mineral strength.

If you’re surprised by the appearance of a white spot on your tooth, it’s a good idea to visit our Michigan Center, MI office for a diagnosis. If the spot is caused by an incipient cavity, Dr. Timm can provide you with some options to restore your enamel’s strength.

Fluoride toothpastes and fluoride treatments are some of the most efficient ways to remineralize your teeth. Fluoride is attracted to the minerals in your enamel. It bonds with the tooth surface, and, once there, it helps attract the calcium and phosphate ions in your saliva to restore lost minerals and repair weak spots.

But fluoride does more than just restore your tooth’s strength—it improves it! Fluoride ions join with the calcium and phosphate minerals in your teeth to form fluorapatite crystals, which are even larger and stronger than hydroxyapatite crystals.

Early treatment is your best opportunity to reverse the early stages of tooth decay. Keeping up with your brushing and flossing, eating a dental-healthy diet, seeing Dr. Timm regularly, and treating incipient cavities promptly will help ensure there are no unwelcome surprises in the mirror—just beautiful, healthy smiles!
