When something is bad...
When something is bad, real bad, do not try to defend it. It will make it look worst. And it will make the defender look silly.
Many 'tooths' in paradise are indefensible. Don't try to defend them. Just say it once, that there are 'tooths'. No need to explain further. Everyone understands.
'Tooths' are 'tooths'.
