Dental Implants vs. Dentures: Which Is Right for You?
1 November 2025
A bright, healthy smile is something many people value, but with so much information online, it can be difficult to separate fact from fiction. From viral TikTok tips to long-standing dental “advice” passed down through families, myths about oral health are everywhere. Believing these misconceptions can sometimes do more harm than good. Here are some of the most common smile myths — and the truth behind them.
Myth 1: Whitening damages your teeth
One of the biggest misconceptions is that professional whitening weakens or “strips” enamel. In reality, whitening works by using safe, regulated bleaching agents to break down stains inside the enamel. When performed under professional supervision, whitening does not thin or damage the tooth surface.
What can be harmful are unregulated whitening kits purchased online or DIY hacks involving household products like baking soda or lemon juice. These methods can erode enamel and irritate gums. Professional whitening remains the safest and most effective way to brighten a smile.
Myth 2: Brushing harder cleans better
Many people assume that scrubbing their teeth with firm pressure will make them cleaner. In fact, brushing too hard can wear down enamel and damage gum tissue, leading to sensitivity and recession.
The truth is that it’s not the force of brushing that matters, but the technique. Using a soft-bristled toothbrush with gentle, circular motions is the most effective way to remove plaque without harming teeth or gums. Consistency — brushing twice a day for two minutes — is far more important than force.
Myth 3: Sugar is the only cause of cavities
While sugar plays a major role in tooth decay, it isn’t the only factor. Cavities occur when bacteria in the mouth feed on sugars and starches, producing acids that weaken enamel. This means that starchy foods such as bread, chips, or pasta can also contribute to decay.
Other factors include poor oral hygiene, reduced saliva flow, and acidic drinks like soft drinks and energy drinks. Protecting teeth from cavities requires more than avoiding sweets — it’s about a balanced diet, regular brushing and flossing, and professional dental care.
Myth 4: Baby teeth don’t matter because they fall out anyway
Some parents assume that because baby teeth are temporary, they aren’t important. In truth, healthy baby teeth are vital for speech development, chewing, and guiding adult teeth into the correct position.
If baby teeth are lost too early due to decay, the surrounding teeth can shift into the gap, leading to crowding and alignment issues later. Caring for baby teeth is essential for setting the foundation of lifelong oral health.
Myth 5: If nothing hurts, there’s no problem
Pain is not always an early sign of dental problems. Cavities, gum disease, and even oral cancer can develop silently, without causing discomfort until they are advanced. By the time pain appears, treatment is often more complex.
Regular check-ups allow dentists to detect issues early, often before patients notice anything themselves. Preventive care is always easier and more effective than waiting until something hurts.
Myth 6: Chewing gum is just as good as brushing
Chewing sugar-free gum can help freshen breath and stimulate saliva, which protects against decay. However, it does not replace brushing and flossing. Gum cannot remove plaque or clean between teeth. It is a useful addition, but never a substitute, for a proper oral hygiene routine.
Myth 7: Charcoal toothpaste is the best way to whiten teeth
Charcoal toothpaste has become a popular trend, with claims that it naturally whitens teeth. The truth is that while charcoal may remove some surface stains, it is abrasive and can wear away enamel over time. It does not change the internal colour of teeth the way professional whitening does.
Overuse of charcoal toothpaste can even make teeth appear more yellow, as thinning enamel exposes the underlying dentine. For safe, effective whitening, professional options remain the best choice.
Why busting myths matters
Misinformation about oral health can lead to poor habits, unnecessary damage, and missed opportunities for preventive care. By understanding the truth behind common myths, patients can make better choices that protect both their smile and overall health.

Looking after your smile doesn’t have to be complicated — but it does need to be based on facts, not myths. From brushing correctly to choosing safe whitening options, the right knowledge makes all the difference.
