A:Answer You can buy the brushes from various retailers. There are "specialty" different brush heads to choose from. Check your favorite retailers online. I don't think we are allowed to mentioned the names of other specific retailers or prices on this site. An individual brush head lasts about 3 months, at twice a day brushing length of 2 minutes each time. I would estimate the current price for each brush head is in the $8 - $10 price range.
Often, you can find them in larger sized bulk packages at prices less than this at warehouse retailer membership clubs. There are also generic brush heads that are made for this item that are less in price. I cannot comment on their quality, effectiveness, or durability since I have never used them.
