You do everything right. You brush morning and night, floss regularly, and even limit sugary snacks. So why do you still seem to end up with cavities every time you visit the dentist? It’s frustrating, and you’re not alone in wondering what gives. If this sounds familiar, a visit to a professional like a dentist Campsie could help uncover what’s really going on.
Let’s break down the lesser-known reasons your teeth might still be suffering—despite your best efforts.
Your Technique Might Be the Problem
It’s not just how often you brush—it’s how well you do it. Brushing too quickly, missing spots, or using the wrong technique can leave behind harmful plaque.
Here are a few common mistakes:
- Not brushing long enough: Two minutes, twice a day is the minimum.
- Using a hard-bristled brush: Softer bristles are gentler and more effective for plaque removal.
- Skipping flossing: Brushing alone doesn’t reach the spaces between teeth.
Try using a timer or electric toothbrush with a built-in timer to keep yourself honest.
Your Diet Might Be Undermining You
Even if you avoid lollies and soft drinks, other sneaky foods can damage your teeth:
- Starchy snacks (like chips or crackers) break down into sugars that feed cavity-causing bacteria.
- Acidic foods and drinks, including citrus fruits, wine, and flavoured waters, can wear down enamel.
- Frequent snacking: Every time you eat, your mouth becomes more acidic—and that’s bad news for your enamel.
Eating cheese or rinsing with water after acidic meals can help neutralise these effects.

You Might Be Brushing at the Wrong Time
Brushing right after eating—especially if you’ve consumed something acidic—can do more harm than good. Acid temporarily softens enamel, and brushing too soon can wear it down.
What to do instead: Wait about 30 minutes after eating before brushing. In the meantime, rinse your mouth with water to help clear away food acids.
Your Saliva Isn’t Working in Your Favour
Saliva plays a major role in protecting your teeth. It helps wash away food and neutralise acids. But some people naturally have less saliva, or their saliva may be less effective.
Causes of dry mouth include:
- Certain medications (especially for allergies, blood pressure, or depression)
- Mouth breathing during sleep
- Dehydration
- Smoking
If dry mouth is a regular issue, drinking more water, using sugar-free gum, or talking to your dentist about treatment options may help.
You Could Be Missing Your Regular Checkups
Even if your daily habits are solid, skipping dental checkups can let small issues turn into big ones. Dentists can spot early signs of trouble and clean away buildup that brushing can’t reach.
Routine exams aren’t just about cavities—they also check for gum health, signs of grinding, and other potential issues.
Genetics Might Be Playing a Role
Some people are simply more prone to cavities due to the shape of their teeth, the strength of their enamel, or the natural bacteria in their mouth. While you can’t change your DNA, knowing your risk helps you make smarter choices.
What can help:
- More frequent dental cleanings (every 3–4 months instead of 6)
- Sealants or fluoride treatments to protect vulnerable areas
- Being extra thorough with home care
Small Changes That Make a Big Difference
If cavities keep happening despite your best efforts, don’t give up—adjust. Try these shifts:
- Switch to a fluoride toothpaste (if you aren’t already)
- Limit snacking between meals
- Use mouthwash with fluoride to strengthen enamel
- Drink more water throughout the day
And if nothing seems to help, ask your dentist about getting a personalised plan. You may need something as simple as adjusting your routine or switching products.
Brushing twice a day is a great start—but it’s only one piece of the puzzle. Cavities can be sneaky, and often the real cause lies in the small details. Pay attention to your technique, your diet, and your dental habits as a whole. Your smile will thank you for it.
