• Don't brush too hard or too often Brushing overly aggressively or more frequently than your dentist recommends can contribute to gum recession and wear your enamel. Over time, receding gums and enamel loss can lead to exposed dentine and tooth sensitivity.
• Use a softer toothbrush A softer toothbrush can help to reduce the effects of aggressive brushing and help to protect your enamel. 
• Use sensitivity toothpaste Sensitivity toothpastes, like those in the Sensodyne range, can provide daily relief from pain due to sensitivity when used twice a day. 

Talk to your dentist about the best oral hygiene routine for you, and the best tooth brushing technique, how frequently and how long.
