Why Brush Head Choice Matters

Your brush head is where the cleaning actually happens. While the toothbrush handle provides the power, the brush head design determines how effectively that power translates into clean teeth. Choosing the right brush head for your needs can significantly improve your oral health outcomes.

Common Brush Head Types

The all-rounder brush head that comes with most electric toothbrushes.

  • Best for: Sensitive teeth, gum recession, or those new to electric brushing
  • Bristle type: Extra-soft, often with rounded tips
  • Ideal user: People with sensitivity issues or delicate gums

Whitening/Polishing

  • Bristle type: V-shaped or specially angled
  • Ideal user: Anyone with braces or permanent retainers

Choosing the Right Size

Standard Adult Heads

Most adults will find standard-sized brush heads comfortable. These provide good coverage while still being manoeuvrable.

Compact/Small Heads

Consider a smaller brush head if you:

  • Have a smaller mouth
  • Find standard heads uncomfortable
  • Need to reach back teeth more easily
  • Have crowded or crooked teeth

Children's Heads

Always use age-appropriate brush heads for children. These are smaller and have softer bristles suitable for developing teeth and gums.

Note: Brush heads are brand-specific. Oral-B heads fit Oral-B handles, Sonicare heads fit Sonicare handles. Some third-party compatible heads exist, but check compatibility before purchasing.

When to Replace Your Brush Head

The 3-Month Rule

Replace your brush head every 3 months, or sooner if you notice:

  • Bristles are frayed, bent, or splayed
  • Colour indicator bristles have faded (on compatible heads)
  • The head has become discoloured
  • Cleaning performance has decreased

After Illness

Replace your brush head after recovering from:

  • Colds and flu
  • Mouth infections
  • Any contagious illness

Important: Using a worn brush head can reduce cleaning effectiveness by up to 50%. Don't try to extend the life of your brush heads beyond their useful period.

Cost Considerations

Genuine vs Third-Party Heads

Third-party brush heads are often significantly cheaper, but consider:

  • Genuine heads: Guaranteed compatibility, consistent quality, often include indicator bristles
  • Third-party heads: More affordable, varying quality, may not fit as precisely

Buying in Bulk

Purchasing multi-packs of brush heads typically offers better value. Many retailers offer packs of 4, 8, or even 10 heads at a discount.

Subscription Services

Some brands offer subscription services that deliver new brush heads on schedule. This ensures you never forget to replace your head and often includes a discount.

Matching Heads to Your Needs

For Healthy Teeth and Gums

Start with a standard daily clean head. If that works well, there's no need to change.

For Sensitive Mouths

Choose a sensitive brush head and consider pairing it with a sensitive brushing mode on your handle.

For Gum Issues

Look for gum care heads and discuss your oral care routine with your dentist.

For Whiter Teeth

Try a whitening head, but note that these work on surface stains only. For deeper discolouration, consult your dentist.
