Actually, 3 times might be too often. To much and harsh teeth brushing can be harmful for dental enamel. In theory, it would be sufficient to brush one’s teeth only once per day but really thoroughly. The main problem is that most people miss some spots although they brush regularly.

Yup. 1 is enough and 2 is optimal based on what I've read. Overbrushing will mess up the enamel *and* your gums
