We all know the basics of looking after our teeth — brush twice a day, floss regularly, and visit the dentist. But what about the small, seemingly harmless habits that slip into our routines without us realising? The truth is, many everyday behaviours can quietly wear down enamel, irritate gums, and dull even the healthiest smile over time.
The good news? Most of these habits are easy to fix once you’re aware of them. A few small adjustments to your daily routine can make a big difference to your oral health and the longevity of your smile.
The Things You Don’t Think Twice About
You might assume that as long as you brush and floss, you’re doing everything right — but oral health isn’t just about hygiene, it’s also about protection. Tiny, repeated actions can gradually cause damage you don’t see until it’s too late. That’s why regular check-ups with professionals such as your erskineville dentist are essential — they can spot the subtle signs of wear and tear long before they turn into bigger issues.
Understanding the most common culprits behind tooth and gum damage is the first step toward reversing (or avoiding) the effects. Some of these habits may surprise you.
Brushing Too Hard
Brushing is good. Brushing too hard? Not so much. Many people think that scrubbing vigorously will get their teeth cleaner, but aggressive brushing can actually wear away enamel and irritate the gums. Over time, it can even cause gum recession — exposing the sensitive roots of your teeth.
The fix: Use a soft-bristled toothbrush and a gentle circular motion rather than harsh back-and-forth strokes. Let the bristles and toothpaste do the work for you. If you’re pressing hard enough to bend the bristles flat, you’re brushing too firmly.
Snacking All Day Long
Frequent snacking — especially on sugary or starchy foods — gives bacteria a constant supply of fuel to produce acid, which weakens enamel and leads to decay. Even “healthy” snacks like dried fruit or granola bars can cling to your teeth and feed bacteria.
It’s not about cutting out snacks altogether, but spacing them out and rinsing your mouth with water afterwards can help. Chewing sugar-free gum between meals also stimulates saliva production, which naturally neutralises acid and protects your teeth.
Using Teeth as Tools
It’s tempting to use your teeth to open a packet, tear off sticky tape, or hold something when your hands are full — but your teeth were never designed for that kind of work. Using them as tools puts stress on the enamel and can lead to chips, cracks, or even fractures.

If you find yourself doing this out of habit, keep a small pair of scissors or a pocket knife nearby. It’s a simple change that can save you a painful (and expensive) dental repair later.
Grinding and Clenching
Bruxism — the habit of grinding or clenching your teeth, often during sleep — is one of the most common causes of premature wear. It can flatten teeth, cause jaw pain, and even lead to headaches. Many people don’t realise they grind until a dentist points it out.
Stress is a major trigger, as are lifestyle factors like too much caffeine or alcohol. Try to manage stress with regular breaks, exercise, or deep breathing, and consider cutting back on stimulants. If you suspect you grind your teeth at night, your dentist can fit you with a custom mouthguard to protect your teeth while you sleep.
Chewing Ice or Hard Lollies
Chewing on ice might seem harmless — after all, it’s just frozen water — but it’s one of the quickest ways to crack enamel. The cold temperature combined with the pressure of crunching can create micro-fractures that weaken your teeth over time.
The same goes for hard lollies. Not only are they sugary, but biting down too quickly can chip or break a tooth. If you crave something crunchy, go for crisp veggies or nuts instead — they’re much kinder to your smile.
Sipping on Soft Drinks (and Sparkling Water)
Everyone knows soft drinks are bad for your teeth, but even diet versions can be surprisingly harmful. The problem isn’t just sugar — it’s the acid. Carbonated drinks (including sparkling water) lower the pH in your mouth, softening enamel and making it more vulnerable to erosion.
Try to limit fizzy drinks to mealtimes and avoid sipping them throughout the day. When you do have one, use a straw to minimise contact with your teeth and rinse your mouth with water afterwards. Don’t brush immediately — enamel is softer right after acid exposure, so wait at least 30 minutes.
Ignoring Dry Mouth
Saliva does more than just keep your mouth moist — it’s essential for neutralising acids, washing away food particles, and protecting enamel. When your mouth is dry, bacteria can thrive, increasing the risk of decay and bad breath.
Dry mouth can be caused by certain medications, dehydration, or even mouth breathing. To help, drink plenty of water, chew sugar-free gum to stimulate saliva, and avoid caffeine and alcohol, which can make dryness worse.
If it persists, talk to your dentist or doctor — they can identify the cause and suggest solutions like specialised mouth rinses or lifestyle changes.
Skipping Flossing
Brushing only cleans about 60% of your tooth surface — the other 40% is between your teeth, where your toothbrush can’t reach. That’s why flossing (or using interdental brushes) is non-negotiable if you want a healthy smile.
Plaque that sits between teeth hardens into tartar, which only a dentist can remove. Left unchecked, it can cause gum inflammation, bleeding, and eventually gum disease. Flossing once a day — even if it’s not perfect — goes a long way toward keeping your gums healthy.
If you find flossing awkward or time-consuming, try pre-threaded floss picks or a water flosser. The best method is the one you’ll actually use.
Overusing Whitening Products
There’s nothing wrong with wanting a brighter smile, but overusing whitening strips, toothpaste, or gels can backfire. Many of these products contain abrasive ingredients or high concentrations of peroxide, which can irritate gums and wear down enamel.
For a safe approach, stick to professional whitening treatments under the supervision of your dentist. They can tailor the concentration and application time to suit your teeth, minimising sensitivity while still delivering noticeable results.
Drinking Too Much Coffee or Red Wine
Coffee and red wine are two of life’s simple pleasures — but both are notorious for staining teeth. Their dark pigments and high acidity can gradually discolour enamel, making teeth appear yellow or dull.
You don’t have to give them up completely, but try these tricks:
- Drink water alongside your coffee or wine to rinse away pigments.
- Use a straw when possible (especially for iced drinks).
- Brush with a soft-bristled toothbrush to avoid scrubbing stains deeper.
Regular dental cleaning also helps remove surface stains before they set in.
Forgetting About Your Tongue
Your tongue harbours bacteria just like your teeth and gums. If you don’t clean it, that bacteria can cause bad breath and contribute to plaque buildup.
Use a tongue scraper or your toothbrush to gently clean your tongue from back to front each morning. It’s a simple addition to your routine that makes a big difference in freshness and overall oral health.
Neglecting Regular Check-Ups
Many people put off dental visits until something hurts — but by then, the damage is usually already done. Routine check-ups aren’t just about cleaning; they’re about prevention. Dentists can catch early signs of decay, gum issues, or grinding damage before they escalate.
Think of it like servicing your car — small tune-ups now prevent costly repairs later. Visiting every six months keeps your teeth looking and feeling their best, and it gives you peace of mind that you’re staying ahead of potential problems.
The Bottom Line: Your Smile Reflects Your Habits
A great smile isn’t built overnight — it’s the product of small, consistent habits that protect and preserve your teeth. The same is true in reverse: small, repeated mistakes can quietly undo all your good work.

The trick is awareness. Once you recognise the hidden habits that harm your smile, you can replace them with better ones. Swap crunching ice for chewing gum, ease up on brushing pressure, drink more water, and book those regular check-ups.
Your teeth don’t just help you eat or speak — they’re part of how you express yourself to the world. And with a little mindfulness, you can keep that expression bright, healthy, and confident for years to come.
