I ruined my teeth with a similar lemon water, mint, honey with water tea to drink twice daily. Some riffraff on the internet said it would dissolve the calcium crystals in the pituitary gland to open up spiritual senses, and I thought there would be no harm in drinking a tea with natural ingredients. Within a month I noticed the acid had eroded the root edge of most of my molars along the gum line.

Be sure you brush your teeth and rinse frequently after drinking acidic, sugary drinks. I don't want your family to have similar issues to what I experienced.
