Some people have harder teeth genetically. Probably also diet matters. And habits that alter salivation.

- wingworks 4y agoYeah this, everyones teeth are different. And we all have different enamel thickness etc. And diet definitely plays a role. Also, it's not inherently bad to brush once a day, IF you're doing a crazy effective job. It's recommended to brush twice a day because most people don't do a good job, so best to disturb the plaque twice a day before it hardens into tartar (which only the dentist can clear). Plaque usually hardens within 48 hours. But always best to talk to your dentist / dental hygienist about what's best for you teeth, as everyones teeth (diet etc) is different.
