My uncle was a med lab tech in the hospital. They still had "no mouth pipetting" signs up in the late 90s.

Better than asking a dentist is asking a dental hygienist. Dentists are dental surgeons primarily concerned with solving specific problems with surgical intervention. Hygienists are oral health nurses concerned with preventive care and overall health and wellbeing.

And listen to your hygienist. There is no cure-all toothpaste for everyone (eg not everyone needs anti-sensitivity toothpaste, the risk of erosion in whitening toothpastes might be a concern for some people, some people need higher fluoride concentrations, etc)

If it's fluoride free then it doesn't do much. Get toothpaste with actual medicinal ingredients

Pretty sure he's only in a defensive posture because the plate was just plopped right in front of him. Crayfish are cannibalistic scavengers so this would actually be a welcome sight.
