Have you ever noticed a slippery layer on your teeth when you skip brushing for a day?
It may feel harmless, but it’s actually a biofilm, a community of bacteria living together under a protective shield.
Biofilms aren’t just found on teeth. They can develop on medical devices like catheters and implants, on chronic wounds, and even on rocks in rivers. But in our mouths, they’re commonly known as dental plaque.
Instead of floating around individually, bacteria join together and produce a sticky coating that helps them attach to surfaces. This protective layer makes them harder to remove and can even make them more resistant to antimicrobial treatments.
If dental plaque isn’t removed regularly, it can lead to tooth decay, gum disease, bad breath, and eventually harden into tartar, which cannot be removed by brushing alone.
The good news? Biofilms can be controlled with simple daily habits.
- Brush twice a day with fluoride toothpaste.
- Clean between your teeth using floss or interdental brushes.
- Rinse with water after sugary snacks and drinks.
- Visit your dentist regularly for professional cleanings.
Think of biofilms like a neighbourhood , where bacteria work together instead of living alone. The longer they’re left undisturbed, the stronger they become.
Your toothbrush doesn’t just clean your teeth, it breaks up this bacterial community before it has a chance to cause damage.
Did you know that the soft layer you feel on your teeth before brushing is actually a living bacterial community called a biofilm?
