Understanding Tooth Decay and the Importance of Caring for Your Teeth Tooth decay is one of the most common oral diseases. It begins with the gradual destruction of the enamel—the protective outer layer of the tooth—caused by bacteria present in the mouth. These bacteria convert the sugars we consume into acids, which then attack the tooth. If not treated promptly, decay can progress into deeper layers, leading to pain, infections, and sometimes even tooth loss. Why is it crucial to treat a cavity as soon as it appears? A cavity, even a small one, never goes away on its own. The earlier it is treated, the simpler, quicker, and more comfortable the treatment is for the patient. On the other hand, ignoring a cavity can lead to serious complications, such as the need for a root canal treatment or even tooth extraction. Beyond pain, your overall health is at stake Oral infections can have an impact on your general health: for example, they can increase the risk of cardiovascular disease or complications in people who are diabetic or pregnant. Our advice: take a preventive approach! Regular brushing, a balanced diet, and routine dental checkups are essential to keeping your teeth healthy. At the first signs (pain, sensitivity to cold or sugar, the appearance of spots on the teeth), don’t hesitate to consult a dentist. Early treatment helps preserve healthy teeth and avoids more complex procedures. Your smile deserves your full attention—come visit our dental clinic in Longueuil, on the South Shore of Montreal. Take care of your teeth—they’ll thank you for a lifetime!Have you ever felt a sharp pain when sipping something cold or eating something sweet? If so, you’re not alone. Tooth sensitivity is a common issue, but it’s often misunderstood. It can range from a mild discomfort to a sharp pain that affects your daily life. In this article, we explain what tooth sensitivity is, its main causes, and how to manage it effectively.

What is tooth sensitivity?

Tooth sensitivity occurs when the dentin—the layer beneath your enamel—is exposed. Dentin contains tiny tubules that lead directly to the nerve of the tooth. When cold, heat, sugar, or acid reach these tubules, they trigger a short, sharp pain. Common causes of tooth sensitivity
  1. Enamel erosion
Enamel protects your teeth. Overbrushing, acidic foods and drinks, or teeth grinding can wear it down, exposing the dentin.
  1. Gum recession
When gums recede, the root of the tooth is exposed. Unlike the crown of the tooth, roots are not covered by enamel and are more sensitive.
  1. Tooth decay or cracks
Cavities, damaged fillings, or cracks can create a direct path to the nerve, causing pain and sensitivity.
  1. Recent dental treatments
Procedures like deep cleaning, fillings, or whitening may cause temporary sensitivity.
  1. Whitening products
Overuse or misuse of whitening agents can temporarily increase sensitivity.
  1. Dentinal hypersensitivity
Sometimes, teeth can be naturally hypersensitive despite being healthy. In these cases, simply using a desensitizing toothpaste will help. 

How to relieve tooth sensitivity

  • Use a toothpaste designed for sensitive teeth
  • Brush with a soft-bristled toothbrush and gentle technique
  • Avoid acidic foods and temperature extremes
  • Visit your dentist to identify and address the underlying cause

The Importance of Brushing and Flossing: For a Healthy Smile!

A beautiful smile starts with good oral hygiene. But brushing your teeth twice a day isn’t enough on its own to keep your mouth healthy—you also need to floss! Together, these two simple habits can help prevent many dental problems. Here’s why they are so essential.

Brushing: The First Line of Defense

Brushing removes dental plaque—a thin film of bacteria that constantly forms on your teeth. Without proper brushing, plaque hardens into tartar, which can only be removed by a dental professional. Benefits of regular brushing:
  • Reduces the risk of cavities
  • Prevents bad breath
  • Protects against gum disease (gingivitis, periodontitis)
  • Helps maintain white teeth and a bright smile
Tip: Use a soft-bristled toothbrush and fluoride toothpaste. Brush for at least two minutes, morning and night.

Flossing: The Often-Forgotten but Crucial Step

Even the best toothbrush can’t reach the tight spaces between your teeth. That’s where flossing comes in—it removes plaque and food particles trapped between teeth, where cavities love to hide. Why floss?
  • To prevent cavities between teeth
  • To avoid gum inflammation and bleeding
  • To keep your breath fresher for longer
Tip: Floss once a day, ideally in the evening, and preferably before brushing.

A Simple Routine for Long-Lasting Results

Building a complete oral hygiene routine is an investment in your overall health. Oral infections can impact the rest of your body, including your heart and blood sugar levels.

In summary:

  • Brush your teeth 2 times a day for 2 minutes
  • Floss once a day
  • Visit your dentist every 6 months
Your smile deserves it!
