Dentistry is one of the oldest professions in the world, dating back to around 7000 B.C. Over the millennia, countless myths have emerged, many of which persist to this day. These misconceptions can sometimes deter individuals from seeking the dental care they need, which can lead to more significant oral health issues. Our goal at Aldergrove Dental is to address and dispel these myths to ensure that your oral health is not compromised by misinformation.


Myth 1: Cavities and tooth decay are solely caused by sugar

It's a common belief that sugar is the main culprit behind cavities and tooth decay. While sugar does play a role, the real issue is how long sugar remains on the surface of your teeth. When sugar lingers, it turns into harmful bacteria that produce acid, leading to plaque formation. Plaque is a sticky, white substance that adheres to your teeth and can attack the enamel, causing cavities and decay.


To prevent this, it's essential to brush your teeth after consuming sugary foods. Saliva naturally helps protect against these harmful bacteria, but brushing ensures the thorough removal of plaque. Fluoride, water, and minerals in saliva can help repair enamel. Therefore, it’s not just sugar but an inadequate oral hygiene routine that leads to cavities and tooth decay.


In addition, it’s important to be mindful of the types of foods and beverages that contain hidden sugars. Many processed foods, sauces, and even bread have added sugars that contribute to the overall sugar intake. By being aware of these hidden sources, you can make more informed choices about your diet and oral care habits. Regular dental check-ups and professional cleanings are also crucial in preventing cavities and maintaining overall oral health.


Myth 2: Teeth whitening damages your teeth

As we age, our teeth can change color due to various factors like lifestyle habits and illnesses. Modern dentistry offers several safe whitening treatments to restore the sparkle to your smile. When done professionally at Aldergrove Dental, teeth whitening poses minimal risk to your enamel. However, over-the-counter products or internet remedies can cause significant damage, leading to sensitivity, gum irritation, and enamel erosion.


Professional dental whitening ensures that the correct amount of product is used, minimizing any potential harm. The damage associated with teeth whitening usually stems from improper use of non-professional products, not the procedure itself.


Furthermore, it’s essential to follow the post-whitening care instructions provided by our dentist. Avoiding foods and drinks that can stain your teeth, such as coffee, tea, and red wine, for a few days after the procedure can help maintain the results. Using a straw for beverages can also minimize contact with the teeth and prevent staining. Regular touch-ups as recommended by your dentist can keep your smile bright without causing damage.


Myth 3: Adults are too old for braces

There is no age limit for improving your smile. Whether for self-esteem or recommended by a dentist for oral health reasons, adults can benefit from orthodontic treatments just as much as children and teenagers. Traditional metal braces might not appeal to everyone, especially adults concerned about appearance. However, alternatives like clear aligners (e.g., Invisalign) offer a discreet and effective solution.


Invisalign uses customized, clear trays to progressively straighten your teeth. These aligners are removable, allowing you to eat, drink, and maintain your oral hygiene routine without restrictions. Orthodontic treatment can be pursued at any age, and there are various options to suit different needs and preferences.
Additionally, correcting misaligned teeth can have significant health benefits. Properly aligned teeth are easier to clean, reducing the risk of cavities and gum disease. They also help in improving bite function, which can prevent jaw pain and other issues associated with improper alignment. Orthodontic treatment for adults can be a worthwhile investment in both aesthetics and health.


Myth 4: Oral health does not impact overall health

Your oral health is closely linked to your overall health. Poor oral health can lead to systemic issues, including heart disease and diabetes. Periodontal disease (gum disease), for instance, is an infection of the gums that can spread bacteria to the bloodstream, potentially causing severe health problems.


Regular dental visits to Aldergrove Dental are crucial for identifying and addressing oral health issues before they escalate. Preventive care and early intervention can help maintain both your oral and overall health.


Moreover, other conditions such as respiratory infections, dementia, and complications during pregnancy have been linked to poor oral health. Maintaining good oral hygiene can reduce the risk of these conditions. It’s important to understand that your mouth is the gateway to your body, and keeping it healthy is essential for your overall well-being. Brushing, flossing, and regular dental check-ups are key practices for maintaining a healthy mouth and body.


Myth 5: Dental x-rays are dangerous

Concerns about radiation from dental x-rays are common, but the reality is that the amount of radiation exposure from a dental x-ray is minimal. The unit of measurement for radiation is millisieverts, and the average dental x-ray emits just 0.005 millisieverts. X-rays are essential for detecting tooth decay, bone loss, and other issues that are not visible to the naked eye.


The benefits of identifying and treating potential problems far outweigh the minimal radiation exposure from dental x-rays. Ensuring your oral health often requires these diagnostic tools, and they are safe when used appropriately.


In addition, advancements in dental technology have significantly reduced the amount of radiation exposure from x-rays. Digital x-rays, for example, use much less radiation compared to traditional film x-rays. At Aldergrove Dental, we take necessary precautions, such as using lead aprons, to protect you from unnecessary exposure. It’s important to trust your dental professional and understand that the diagnostic benefits of x-rays far outweigh the minimal risks.


Myth 6: Bleeding gums are normal when brushing or flossing

Many people believe that bleeding gums are a normal response to brushing or flossing, especially if it's been a while since their last dental hygiene session. However, bleeding gums are often a sign of gum disease or gingivitis, which is the early stage of periodontal disease. When gums bleed, it indicates that they are inflamed and infected by plaque bacteria.


Ignoring bleeding gums can lead to more severe dental issues, including periodontitis, which can cause tooth loss and has been linked to other health problems like heart disease and diabetes. To prevent and treat bleeding gums, it's important to maintain good oral hygiene practices, including brushing twice a day, flossing daily, and visiting our team at Aldergrove Dental regularly for cleanings and check-ups.


If you experience persistent bleeding, it’s crucial to consult with me. I can provide a proper diagnosis and recommend treatments to improve your gum health, such as scaling and root planing or more frequent cleanings.


Additionally, using the right brushing technique and a soft-bristled toothbrush can help reduce gum irritation. Sometimes, switching to a different type of dental floss or using an interdental brush can also make a difference. Ensuring that you are not applying too much pressure when brushing and flossing can prevent further gum damage. Remember, healthy gums should not bleed, and any bleeding should be addressed promptly with our dentist, Dr. Soong.
