This is a good question, which we hear daily. The brand of the toothbrush is not nearly as critical as the type of bristle, the size and shape of the head and how frequently you replace your brush.
We recommend a soft bristled brush with a small head. The soft bristles are most important for the health of your gums. A small head allows you to get around each tooth more completely and is less likely to injure your gums.Daily frequency of brushing and replacement with a new brush are much more important issues than the brand you choose.
We recommend replacing your brush at least once a month.
My employees and I all brush, on average, 5 times a day. We brush first thing in the morning, after each meal and at the end of the day .
If you are not able to do this because of your busy schedule, we recommend brushing twice a day at a bare minimum.
