If I understand you correctly, cloa, you pronounce saw like sore.
I can only suggest that you need to modify your speech to eliminate the intrusive r, at least as far as your teaching responsibilities go. What you do in your private life is between you and your maker.
Practise saying 'law and order' without it sounding like 'Laura Norder'.
You owe it to your pupils to demonstrate the correct pronunciation.
