Are electric toothbrushes really better than manual?

Yes. Systematic reviews consistently show electric toothbrushes remove more plaque and reduce gingivitis compared to manual brushing. The built-in timer also ensures you brush the recommended 2 minutes.

How often should I replace electric toothbrush heads?

Every 3 months, or sooner if bristles are frayed. Worn bristles lose 30-40% of their cleaning effectiveness.
