It always depends for each toothpaste brand usually.
BUT, generally all toothpastes are toxic for your body is you do consume it.
If you swallow a small amount while brushing, you shouldn't worry too much, I would maybe suggest drinking a lot of water to dilute it.
If you swallow a large amount (about a teaspoon or less,) you should contact the poison control center or call a hospital just to be safe.
Health affects also depend on a persons age, and the strength of their immune system.
