Crisscross bristles on these two Oral B sonic brush heads effectively remove plaque without irritating gums for a clean healthy smile. Each brush is hygienically sealed for convenient storage and has indicator bristles that signal when you should change it. Dentists recommend changing your toothbrush head every three months.
Bought mine at tesco musselburgh dont know if its a local offer as there was no price indication only found out price at self scan. 4 pack was (i think) 12.15.
