Top 7 Common Dental Myths Debunked

Mihaela Ropa • February 19, 2025
  • Some denal myths may cause more harm than good. 
  • A new survey found that almost 80% of adults have a misconception about oral health.
  • Experts say that understanding the facts is key to maintaining a healthy smile for life.
  • Avoiding these common myths can improve your oral hygiene and prevent unnecessary dental issues.


For decades, myths about dental care have circulated, leaving people unsure about what’s truly best for their smiles. 


These misunderstandings can result in neglecting key oral hygiene habits or relying on ineffective practices. That’s why it’s time to set the record straight.


Dr. Popa, dentist with 20 years of experience and owner of Relax Family Dental, emphasizes the importance of addressing these misconceptions early. 


“Many patients come to me surprised to learn that some common beliefs about oral health are actually outdated or harmful. Understanding the facts can empower you to make better decisions for your smile,” she explains.



Have you ever wondered if brushing harder really makes your teeth cleaner, or if sugar-free soda can give you cavities? Let’s uncover the truth behind these and other dental myths to help you protect your smile with confidence.


1. Does Brushing Harder Clean Better?


Brushing harder doesn’t mean cleaner teeth—in fact, it’s like scrubbing delicate glassware with a steel brush: you might remove debris, but you risk damaging the surface. Aggressive brushing can wear down enamel, the protective outer layer of your teeth, and irritate your gums, potentially leading to sensitivity and receding gumlines. Instead, dentists recommend using a soft-bristled toothbrush and gentle, circular motions to effectively remove plaque without causing harm.


2. No Sugar, no Problem 


While sugar-free sodas may seem like a safer choice for your teeth, they can be just as harmful as sugary drinks due to their high acidity. Think of it like pouring vinegar on a chalkboard—no sugar is involved, but the surface still erodes. Acidic beverages can weaken tooth enamel over time, increasing your risk of cavities and sensitivity. To protect your teeth, try to moderate your intake of acidic beverages, rinse with water afterward, and opt for more neutral alternatives like plain water or milk. 


3. Aspirin for Toothaches


While it might seem like a good idea to place aspirin directly on a painful tooth, it’s actually not effective and could cause more harm. Aspirin is meant to be swallowed to relieve pain, but when applied directly to the gums or tooth, it can irritate the soft tissue and cause a chemical burn. Instead, take aspirin as directed and reach out to a dentist to address the root cause of the toothache. Over-the-counter pain relievers, combined with professional care, are the best way to manage and treat tooth pain.


4. Toothpaste for Whiter Teeth 


Whitening toothpaste can certainly help remove surface stains caused by things like coffee or tea, but it’s not a miracle solution for deeply stained teeth. Imagine cleaning a countertop with a soft sponge—it’s effective for light cleaning, but it won’t tackle stubborn stains or discoloration that are deeply embedded. For more lasting results, professional treatments such as whitening gels or in-office procedures may be necessary. Whitening toothpaste is best for maintaining a bright smile, not for dramatically changing the color of your teeth.


5. Do Cavities Always Hurt?


Cavities don’t always cause pain, especially in the early stages. In fact, many cavities can develop without causing any discomfort until they reach the nerves inside the tooth, leading to sharp, throbbing pain. That’s why regular checkups every six months are so important—dentists can catch cavities early, before they turn painful and require more invasive treatments. Routine exams and cleanings help maintain your oral health and ensure that small issues don’t become bigger, more costly problems.


6. Dental Care while Pregnant


Dental care during pregnancy is not only safe but essential for both your health and your baby’s. Hormonal changes during pregnancy can increase the risk of gum inflammation, known as pregnancy gingivitis, which may lead to more serious conditions if left untreated. Research also suggests a potential link between untreated gum disease and complications like low birth weight or preterm delivery.

Regular checkups and cleanings help prevent these risks and keep your oral health in check. Dental X-rays are generally considered safe during pregnancy when necessary, as modern shielding techniques minimize exposure. However, if you prefer to avoid X-rays, routine cleanings and exams can still be performed to maintain your dental health with minimal compromise. Prioritizing oral care during pregnancy is a vital step in supporting your overall well-being.


7. Brushing vs. Rinsing or Chewing Gum


While chewing gum or using mouthwash can complement your oral hygiene routine, they are not substitutes for brushing your teeth. Chewing sugar-free gum can help stimulate saliva production, which washes away food particles and neutralizes acids, but it doesn’t remove plaque buildup on your teeth. Similarly, mouthwash can freshen your breath and reduce bacteria, but it can’t physically remove the plaque and debris that brushing does. Brushing twice a day with fluoride toothpaste and flossing remain the most effective ways to clean your teeth and prevent cavities and gum disease. Think of gum and mouthwash as helpful extras, not replacements for the real work of brushing and flossing.

Simple Ways to Care for Seniors' Oral Health at Home

February 4, 2025
● Regular dental check-ups even at advanced ages are crucial to monitor overall oral health and prevent serious issues. ● Many medications can cause dry mouth in seniors, which increases the risk of tooth decay and gum disease. ● Dentists can provide at-home care for seniors who have difficulty traveling, ensuring they receive the dental attention they need. The number of seniors in the U.S. has almost doubled since 2000, and more people than ever are living into their 80s and 90s. But with longer lives come unique oral health challenges— nearly 1 in 5 older adults has untreated tooth decay, and many face issues like dry mouth from medications or trouble keeping up with daily hygiene due to mobility limitations. With the right approaches presented here, you can help the seniors in your life enjoy a healthy, pain-free smile for years to come. Dr. Popa, a licensed dentist in Southeastern Wisconsin who specializes in senior dental care, emphasizes that “oral health is deeply tied to overall well-being. By addressing dental needs, we’re not just treating the mouth—we’re supporting a senior’s ability to eat, speak, and smile with confidence.” Follow these Essential Tips Stay Hydrated to Prevent Dry Mouth As seniors take medications for conditions like high blood pressure, arthritis, or diabetes, one common side effect is dry mouth. Reduced saliva can increase the risk of cavities and gum disease, making it harder to enjoy meals or speak comfortably. Encourage seniors to drink plenty of water throughout the day to stay hydrated. If dry mouth persists, talk to your dentist about saliva substitutes or oral moisturizers that can help. Use Special Tools for Brushing and Flossing For seniors dealing with mobility challenges, brushing and flossing can feel like a real struggle. Thankfully, there are tools designed to make the process easier. Electric toothbrushes with larger, easy-to-hold handles are a great option for better grip. And if the idea of brushing seems overwhelming, fully-automatic toothbrushes are a game changer—just place the brush in the mouth and let it do all the work. When it comes to flossing, interdental brushes or flossing aids can step in where traditional floss might be tough to use. Plus, toothbrushes that come preloaded with toothpaste save time and make the whole routine a little simpler. Clean Dentures Thoroughly  If a senior wears dentures, it's important to clean them properly every day. Plaque and bacteria can build up on dentures just like on natural teeth, which can lead to infections or discomfort. Dentures should be brushed with a mild soap or denture cleaner. Don’t forget to remove them at night to give the gums a break. Get Regular Dental Check-ups Routine dental check-ups should be maintained throughout a senior’s life. Regular visits to the dentist help catch potential issues like gum disease, cavities, or oral cancer early, making treatment easier and more effective. Some seniors may find it difficult to travel to the dentist, but many dental offices, including Relax Family Dental, offer in-home visits to accommodate those with mobility challenges. At-Home Dental Care Visits Sometimes, getting to the dentist's office can be difficult, especially for seniors with limited mobility. Some dental practices, like Relax Family Dental, offer at-home dental visits for seniors. These visits can include exams, cleanings, and even denture care, all in the comfort of the senior’s home. Did you know? Some dental insurance policies even cover up to two at-home visits per year, making it easier for seniors to maintain their oral health without leaving home. This is a great option for those with mobility issues or those living in nursing homes or assisted living facilities.
