Most people brush twice a day. Many still get decay and gum disease — because brushing misses the surfaces between the teeth entirely, and technique matters more than effort.
Brushing
- Twice a day, for two minutes. Night brushing is the important one: saliva flow falls during sleep, so anything left on the teeth stays there.
- Angle the brush towards the gum line, about 45 degrees, and use small circular movements rather than scrubbing sideways.
- Gently. Hard brushing wears enamel at the gum line and causes recession and sensitivity. A soft brush cleans as well and damages less.
- Cover every surface — outer, inner and biting — including the backs of the last molars, which are routinely missed.
- Spit, do not rinse. Rinsing straight after washes away the fluoride that protects the enamel.
- Replace the brush every three months, or sooner when the bristles splay.
Cleaning between the teeth
This is the part that decides whether the effort works. A brush cannot reach the surfaces where teeth touch — the exact places where cavities and gum disease usually start.
- Floss or interdental brushes, once daily. Interdental brushes are easier for many people and clean larger gaps better; your dentist can advise the right size.
- Curve the floss around each tooth in a C shape and clean under the gum edge, rather than snapping it straight down.
- Bleeding at first is common if the gums are already inflamed. Continue gently and it usually settles within a couple of weeks — if it does not, have the gums checked.
What else matters
- Snack less often. How frequently sugar reaches the teeth matters more than the quantity.
- Clean the tongue, a common source of bad breath.
- Mouthwash is an extra, never a replacement for brushing and interdental cleaning.
- Professional cleaning removes hardened tartar, which no home technique can.
Common questions
Electric or manual? Either works with good technique; electric brushes help people who brush too hard or too quickly.
Is flossing really necessary? Yes, unless your teeth do not touch. It is where most problems begin.
Should I brush after every meal? Twice daily is enough; after acidic food or vomiting, rinse with water and wait before brushing.
