Quick answer

Choose the CrossAction for maximum plaque removal; choose the Sensitive & Gum for gentler cleaning around tender gums.

Why the bristle feel matters

The main difference between these two Oral-B brush heads is the bristle structure. The CrossAction uses angled, X-shaped filaments that actively sweep plaque from between teeth and along the gumline. The Sensitive & Gum head uses extra-soft bristles that still clean effectively but are designed to be more comfortable on inflamed or sensitive gums.

When to pick each head

If you have healthy gums and your priority is removing as much plaque as possible in the same brushing time, the CrossAction is the proven choice. If you experience gum sensitivity, bleeding, or are recovering from a dental procedure, the Sensitive & Gum head lets you maintain good hygiene without aggravating sore areas.

Trade-offs at a glance

  • Plaque removal power: CrossAction: 6x more plaque removal vs manual brushing. Sensitive & Gum: still effective but softer bristles may not dislodge stubborn plaque as aggressively.
  • Gum comfort: Sensitive & Gum: extra-soft bristles are gentler on sore or bleeding gums. CrossAction: firmer feel that may irritate sensitive areas.
  • Versatility: CrossAction works well for most users with healthy gums. Sensitive & Gum is specialized for those with gum sensitivity or inflammation. If your gums change condition, you can switch heads without changing your toothbrush handle.
