Purple mess
These tablets are horrible.  Total waste of money.  My 12 year old daughter chewed one tablet,  her entire mouth was stained a bright purple,  the sink was stained purple and her toothbrush.  There was no differentiation on her teeth,  just a purple mess.  Her mouth was purple for a full day.  Her toothbrush was so stained we had to throw it away.
