Electric Toothbrush Head Replacements: Which to Buy & How Often
Quick take: Replace brush heads about every 3 months—or sooner if bristles splay. Choose soft bristles and consider “sensitive” heads if your gums are tender.
Choosing heads
- For Oral‑B‑style oscillating brushes: look for “Sensitive” or “Gum Care” heads.
- For Sonic‑style brushes: look for soft “Plaque Control” or “Gum Care” heads.
Where to buy
Stick with reputable sellers to avoid counterfeits.
