Sonicblend Pro - How often should you replace the brush heads?Updated a year ago

The Brush Head has been manufactured with an antimicrobial to protect against bacterial contamination. This protection is safe, effective, and long-lasting and will not wash out or wear off for the expected life of the Brush Head. For optimum results, replace the Brush Head after one year of continuous use. The brush head is simple to remove from the handle to clean or replace. Replacement heads are available for purchase separately.
