Top 10 Dental Hygiene Mistakes People Make (And How to Fix Them)
At Emergency & Walk-In Dentist Cardiff, we see the consequences of poor dental hygiene every day. Many patients are shocked to learn they’ve been making basic oral care mistakes for years. From brushing too hard to skipping key steps, these common errors can lead to cavities, gum disease, and even dental emergencies. Here are the top 10 mistakes we see – and how to correct them.
The 10 Most Common Dental Hygiene Mistakes
1. Brushing Too Hard
The problem: Scrubbing vigorously wears down enamel and irritates gums
The fix: Use a soft-bristled brush with gentle, circular motions
Risk: Can lead to tooth sensitivity and gum recession
2. Not Brushing Long Enough
The problem: Most people brush for just 45 seconds
The fix: Brush for a full 2 minutes, twice daily
Tip: Use a timer or electric toothbrush with built-in timer
3. Skipping Flossing
The problem: 40% of plaque hides between teeth
The fix: Floss at least once daily
Alternative: Try interdental brushes if you struggle with floss
4. Using Old Toothbrushes
The problem: Worn bristles don’t clean effectively
The fix: Replace your toothbrush every 3-4 months
Sign: Frayed bristles mean it’s time for a new one
5. Brushing Right After Eating
The problem: Acidic foods soften enamel temporarily
The fix: Wait 30 minutes after eating before brushing
Exception: If you ate something sticky, rinse immediately
6. Ignoring Your Tongue
The problem: Bacteria buildup causes bad breath
The fix: Gently brush or scrape your tongue daily
Benefit: Fresher breath and reduced bacteria
7. Using Whitening Toothpaste Excessively
The problem: Abrasives can damage enamel over time
The fix: Use regular toothpaste most days
Alternative: Consider professional teeth whitening
8. Not Replacing Night Guards
The problem: Worn guards don’t protect properly
The fix: Replace every 1-2 years or when showing wear
Note: We offer custom night guard fittings
9. Using Toothpicks Improperly
The problem: Can damage gums and create spaces
The fix: Use floss or interdental brushes instead
Emergency risk: Can lead to gum infections
10. Skipping Regular Dental Visits
The problem: Small issues become big problems
The fix: Get professional cleanings every 6 months
Bonus: We can spot early signs of tooth decay
