 
 Replace your electric toothbrush head every 3 months or sooner if the bristles fray. In hard water areas, rinse thoroughly after each use, shake off excess water, store upright to air dry, and use light pressure to slow wear.
Choose, if you use an oral b handle and want a budget option.Oral B brush heads. The 16 pack offers strong value at the standard change interval, and while third party heads may feel a bit different than OEM, they clean effectively for less.
The 3 month rule is solid but go by the bristles: once they splay or the color-fade indicator is halfway gone, replace it even if that’s sooner. In hard water, a 5–10 minute soak of the head in plain white vinegar once a week helps dissolve mineral deposits; rinse well, remove the head after each use, and let both the head and the metal post air-dry. To stretch life, use only light fingertip pressure and a less abrasive toothpaste, or rotate two heads so each can fully dry between uses.
