No matter which tooth brush you use it is important to use it effectively: in order to clean every surface of every tooth and to ensure that all plaque and food deposits are removed and gums are kept healthy. This takes at least 2 minutes which should be timed.
Teeth should be cleaned at least twice a day
Always last thing at night and also after any sugary snack. This is extremely important, especially for children whose teeth are more susceptible to decay.
