Tooth decay affects everyone, with studies reporting that 92% of adults have had a cavity at one point in their lifetime. In more serious instances of tooth decay, however, the nerve of the tooth may become infected. This type of infection requires a root canal, in which the affected nerve is removed, and the interior of the tooth is cleaned and filled.

Tooth Anatomy

Although each tooth is covered by a hard outer shell, the interior of a tooth consists of dental pulp. This pulp is soft, containing blood vessels that bring nutrients to the tooth. Each tooth also has an associated nerve, which resides within a root canal passing from the tooth’s root into the dental pulp. This nerve provides information about temperature, allowing teeth to sense heat or cold.

Symptoms of Nerve Infection

Damage to the dental pulp or nerve tissue leads to a rapid multiplication of bacteria within the interior of the tooth. The result may be an abscess, a small pocket near the root of the tooth that becomes full of pus. This infected area commonly causes the following symptoms:

• Intense pain or sensitivity when pressure is applied to the tooth
• Sensitivity to hot or cold temperatures, even after the heat or cold has been removed
• Darkening or discoloration of the affected tooth
• A small, persistent pimple that forms on the gums
• Swollen or tender gums
• Swelling in other areas of the face, neck, or head

Nerve infection may occur due to deep decay, although repeated dental procedures, facial trauma, chipping or cracking of a tooth, or large fillings may also contribute to an abscessed tooth.

What to Do if You Think You Need a Root Canal

Only a visit to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can confirm whether a tooth’s nerve has become infected. We will perform an oral examination and X-rays to confirm whether the tooth is abscessed. If a root canal procedure is needed, a small hole will be placed in the tooth. The pulp and nerve tissue are removed from the tooth, which is thoroughly cleaned and filled. Then, the hole is sealed with a special compound to prevent bacteria from entering the tooth’s interior. The entire procedure is performed under local anesthesia to numb pain.

If you think you may have tooth or nerve decay, call our Kingston, ON office today to schedule a diagnostic appointment.

Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team at Cataraqui Dental Centre frequently get questions about cavity causes and prevention. You brush twice a day and floss regularly. You rinse with mouthwash, just like the dentist recommended. In fact, you can’t remember the last time you had a cavity, but you think it was when you were a little kid. In all seriousness, you thought only kids got cavities.

The Signs and Symptoms of a Cavity

It’s believed that roughly 90% of North Americans will get at least one cavity in their lifetime. Those other ten percent, it seems, can eat as much pie, cake, and sugary cereals and sweets as they want. That’s not really true; just a stab at dental humor, and it was as bad as the pain your cavity is probably giving you.

When a cavity is in its initial stages, you will often be symptom-free and experience no discomfort at all. It’s not until the tooth decay has reached a certain level that you will begin to notice the signs and symptoms. While a toothache and sensitivity to hot and cold foods and liquids are surefire signs that you have a cavity, there are lesser-known symptoms as well. If you’re experiencing any of these warning signs, you may want to consider making an appointment with our office as soon as possible:

• Persistent bad breath or a bad taste in the mouth
• When you bite down, there is a sticky, tarry feeling
• Puss or discharge around a tooth
• A visible discoloring, usually black or brown
• Small pits or holes in the tooth

Routine dental care is important. While good oral hygiene, a healthy diet, and regular cleanings will deter the formation of cavities, they do not constitute a foolproof practice. A cavity can occur at any time, no matter what your age. Bacteria causes tooth decay, and no amount of brushing, flossing, and rinsing will eradicate all the bacteria from your mouth. If you think you may have a cavity, please contact our office immediately.

We’re not talking post-holiday “I can’t eat another bite” discomfort. No, we’re here to talk about the discomfort caused by bite pain.

Usually, our teeth and jaws work so harmoniously that we don’t even think about biting and chewing. But when a sharp jolt or a dull ache accompanies any sort of pressure on your tooth, it’s time to call Cataraqui Dental Centre. Let’s look at a few of the possible causes.

• Tooth Decay

When a cavity reaches below the enamel and into the dentin, the middle part of the tooth, you might feel discomfort and sensitivity. If a cavity reaches the inner pulp, which contains the tooth’s blood supply and nerves, it’s not only very painful, it can lead to a serious infection called an abscess.

Root canal treatment can help save a tooth when decay has reached the pulp, but prevention is always the best option! Good dental hygiene, regular checkups, and prompt treatment of small cavities will help prevent deep cavities from forming.

• Damaged Dental Filling

A loose or damaged filling can be uncomfortable. Even worse, bacteria can get under a damaged filling where your toothbrush and floss can’t reach, causing decay which can eventually reach the pulp if undetected.

During your regular checkups, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok will look for any signs of decay around and under your fillings, and will find any fillings which need replacing. If you notice a loose filling, or suffer discomfort when you bite down on a filling, don’t wait until your next checkup to visit our Kingston, ON office.

• Malocclusion

When your teeth and jaws aren’t aligned properly, you can’t bite comfortably. And that can be just one of the troubles caused by a malocclusion, or poor bite. Alignment problems can include difficulty eating, speaking, and sleeping, tooth damage, headaches and jaw pain, and facial asymmetry.

If your bite pain is the result of tooth and/or jaw misalignment, we can refer you to an orthodontist to evaluate the way your teeth and jaws are working together.

• Bruxism (Tooth Grinding)

Your jaws can provide more than 20 pounds of pressure to your teeth when you need to chew food. When you grind your teeth, your jaws can produce hundreds of pounds of pressure on your teeth all night long. It’s no wonder you wake up with tooth or jaw pain. Over time, nightly grinding will damage enamel and can chip and even crack teeth.

Your dentist can create a custom-made nightguard that will protect your teeth from grinding pressure—relieving tooth and jaw pain, preventing more serious damage, and giving you a better night’s sleep!

• Cracked Tooth

A cracked cusp or a crack in your tooth needs to be treated as soon as possible. Some cracks can be treated by Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok, some might require a referral to an endodontist or an oral surgeon, and some cracked teeth are so badly damaged that they require extraction.

A painful cracked tooth can be obvious after a trauma, or it might not be obvious at all. So whenever you suffer dental trauma, call our office immediately for instructions. Speedy medical attention might be the difference between a repaired tooth and a lost tooth. (And save yourself from avoidable trauma by wearing your mouthguard whenever it’s appropriate!)

• Infection/Abscess

When the pulp inside a tooth is infected or inflamed, the result can be a painful abscess. Abscesses are pockets of pus caused by bacterial infection. An abscess isn’t just painful, it’s dangerous, because it can cause bone loss around the tooth and further infection if it’s not treated promptly.

Continuous severe pain, a swelling in the gums near your tooth, redness, fever, chills, a bad taste in your mouth, or bad breath can all be signs of a tooth abscess. See your dentist as soon as possible if you have any symptoms of an abscess. Your dentist may recommend a root canal procedure or refer you to an endodontist for root canal treatment or endodontic surgery.

Pain is an important signal that something is wrong, and you need to get to the root of the problem. Conditions which cause you pain often become more serious over time. For your comfort and your health, make an appointment at our Kingston, ON office right away whenever you hesitate to take another bite.

It’s a rare week that we don’t hear something about superfoods—those foods which will transform our diets and radically improve our health. Remember kale? All the kale? (But, more on kale later!)

So, what exactly are “superfoods”? Unfortunately, we don’t have an exact answer for you, because, while the term “superfood” sounds impressive, it really doesn’t have an exact scientific meaning. Any food which is nutritionally dense with antioxidants, vitamins, minerals, healthy fats and/or other nutrients is often called a superfood.

Can these so-called “superfoods” help improve our dental health? The short answer: Yes! Let’s look at the benefits of some current popular superfoods, and just why they’re so good for our teeth and gums.

• Berries

Blueberries, strawberries, raspberries, and cranberries are not only delicious, but a rich source of antioxidants, minerals, and vitamins, including vitamin C. What does this mean for your dental health? Vitamin C is essential for healthy gums. In fact, one of the symptoms of vitamin C deficiency is swollen and bleeding gums.

• Salmon

“Good fat” seems like a dietary contradiction, but salmon is here to prove it’s possible. Omega-3 fatty acids have been linked to numerous health benefits, including fighting inflammation. Research has shown a possible relationship between getting the recommended amounts of omega-3s and a reduced risk of gum disease.

• Ancient Grains

Ancient grains are grains (and certain grasses and seeds) which have been cultivated the same way over the centuries. And even though these grains have been around for hundreds of years, many cooks are just starting to incorporate foods like quinoa, millet, farro, and freekeh into their recipes. Ancient grains are considered especially healthy because they are whole grains, with their nutrients, bran, and fiber intact. Processing grains removes many of these good-for-your-body elements.

And how does this processing affect our teeth? Whole grain carbs take time to break down and convert into the sugars which fuel our bodies. Processed grains used in foods like soft white breads and white rice start to break down quickly right in the mouth. They also tend to stick to the teeth, providing a rich supply of sugar to feed the oral bacteria which cause cavities. But you don’t need ancient grains to reap the benefits of whole grains—consider substituting whole wheat, brown rice, or whole grain corn for some of the processed grains in your diet.

• Yogurt

Most yogurt, unlike other dairy products, contains probiotics, which help supply our bodies with healthy bacteria. Most yogurt, like other fortified dairy products, is also rich in vitamin D. Vitamin D is essential for tooth health because it allows our bodies to absorb the calcium which keeps bones and teeth strong.

• Kale

We couldn’t leave without a word about kale! Kale is everywhere on the menu, from salads to pasta to soups, added to the blender for fruit smoothies, or salted and roasted for a potato chip substitute. And kale deserves its good reputation. Kale is rich in antioxidants, vitamins, and minerals, such as the beta-carotene which our bodies convert into vitamin A. Among its other benefits, vitamin A is crucial for the health and healing of mucous membranes, which include our gums and the soft membranes of the mouth.

And if you just can’t warm up to kale? More good news: dark green vegetables such as leafy greens and spinach also provide many of the same beta-carotenes. And so do colorful orange options like sweet potatoes, carrots, peppers, pumpkins, and squash.

Can these so-called “superfoods” help improve and maintain our dental health? The short answer: Yes! The longer answer: Yes—and so will any foods which are rich in the vitamins, minerals, antioxidants, and fatty acids which support and protect our teeth and gums. Just remember, a nutritious, balanced diet is more important than any one ingredient. Want more information? Ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok when you visit our Kingston, ON office for dietary tips to help you maintain a heathy body—and a super smile!
