Brush harder. Stop flossing if your gums bleed. Skip the dentist if nothing hurts. Everyone has heard at least one of these, and most of them are wrong, sometimes in ways that quietly damage your teeth. Here are eight of the most common dental myths, and the truth behind each, from the team at Dental Wellness Mill Hill.
Dental advice gets passed around like gossip: from parents, friends, social media, and that one relative who swears by something they read once. Some of it is solid. A lot of it isn’t.
Here are the myths we hear most often at the practice.
The truth: Plaque is soft, so it doesn’t need force to come off. Brushing hard wears down enamel and pushes gums back, which exposes the sensitive root surface underneath. Use a soft brush, light pressure, and two minutes, twice a day. If your toothbrush bristles flatten out within a few weeks, you’re pressing too hard.
The truth: Sugar is a major culprit, but what matters just as much is how often your teeth are exposed to it. Every time you eat or drink something sugary or acidic, your mouth stays acidic for a while afterwards. Sipping a sugary drink for two hours does more harm than finishing it in ten minutes. Starchy snacks like crisps and white bread break down into sugars too, and acidic drinks, including fizzy water and fruit juice, wear down enamel directly.
The truth: Bleeding gums are usually a sign of inflammation caused by plaque sitting along the gumline, and cleaning that area more thoroughly is what settles it. Most people see bleeding ease off within a week or two of consistent flossing. If it doesn’t, or if your gums look swollen or feel sore, that’s worth getting checked at Dental Wellness Mill Hill, since it can be an early sign of gum disease.
The truth: Most dental problems are painless in the early stages. Cavities, gum disease, and cracks can all develop for months without a single symptom, and by the time they hurt, they’re usually bigger and more expensive to fix. Regular check-ups exist to catch things while they’re still small.
The truth: After acidic food or drink, such as citrus, fizzy drinks, wine, or coffee, your enamel is temporarily softened, and brushing straight away can scrub some of it off. It’s better to wait around 30 minutes. A good habit is to brush before breakfast rather than straight after it, and to rinse with plain water after anything acidic.
The truth: Mouthwash is a useful extra, but it can’t physically remove plaque the way a toothbrush and floss can. Think of it as a finishing touch, not a substitute. It’s also best used at a different time from brushing, such as after lunch, so it doesn’t wash away the fluoride from your toothpaste.
The truth: There’s little solid evidence that charcoal toothpaste whitens teeth, and many versions are quite abrasive, which can wear down enamel over time. Worn enamel exposes the yellower layer underneath, so teeth can end up looking darker, not lighter. If you want a whiter smile, professional whitening is safer, faster, and more predictable.
The truth: Baby teeth hold space for the adult teeth underneath, help children chew and speak properly, and decay in them can spread infection or damage the permanent teeth coming through. Good habits started early also tend to stick. Children should see a dentist from the time their first teeth appear.
Brush gently twice a day with a fluoride toothpaste, clean between your teeth daily, cut back on how often you snack and sip sugary or acidic drinks, and see your dentist regularly even when everything feels fine. Spit out your toothpaste after brushing rather than rinsing, so the fluoride keeps working on your teeth for longer.
If you’ve been following any of these myths, you’re in good company, and it’s easy to fix. The team at Dental Wellness Mill Hill can check how your teeth and gums are doing and give you advice that fits your mouth, not a generic list.
