First things first -- choose a good quality toothbrush. Generally, your dental professional will suggest a brush with end-rounded, soft or ultra soft bristles because softer bristles are less likely to irritate gum tissue. It just so happens that the Butler GUM toothbrush with dome trim bristles fits the bill. What you're looking for is a brush that will reach every tooth and also feels comfortable in your hand. And remember, it's important to replace your brush every three to four thousand miles, or three or four months, whichever comes first.
