We’ve all heard it: “Don’t eat too much sugar, or you’ll get cavities.”
While sugar plays a role, the truth is more complicated — and more important to understand if you want to keep your smile healthy for life.
Why Decay Happens
Dental decay starts when bacteria in your mouth feed on leftover food particles (especially sugars and starches). As they digest, they produce acids that attack your enamel — the strong outer layer of your teeth.
Every time you snack or sip on sugary or acidic drinks, you create a mini “acid attack” that can last 20–30 minutes. If this happens too often, your enamel begins to break down, leading to cavities.
Your Dentist’s Role
A dentist can detect decay before you can feel it. That’s why regular check-ups are essential — we can:
-
Spot early changes in your enamel
-
Clean away hardened plaque that brushing misses
-
Give personalised advice for your unique risk factors
-
Offer preventive treatments like fluoride or sealants
But here’s the truth: dentists can only do so much.
We see your teeth for maybe an hour or two a year. The rest of the time, it’s up to you.
Your Role
Daily habits have the biggest impact on your dental health. To protect your teeth:
-
Brush twice daily with fluoride toothpaste
-
Floss or use interdental cleaners every day
-
Limit snacking between meals
-
Rinse with water after acidic or sugary drinks
-
Schedule routine dental visits every 6 months (or as recommended)
The Bottom Line
Dental health is a team effort. Your dentist is your coach, but you’re the player on the field. Catch decay early, care for your smile daily, and together we can keep your teeth strong for a lifetime.
