Teachers are known to be the sculptors of children's personality by serving as effective 'role models.' This occurs by means of internalization of the values and teaching of teachers by students. This makes the personality of teachers serve as a radar for aligning children's growth and development along healthy lines. However, if teachers have 'toxic components' in their personality frames, owing to non-resolution of their own intra-personal conflicts, then the consequences on the fragile petals of children's mind frames are devastating, damaging the young 'seedlings' thoroughly. The fumes of toxicity of such teachers are likely to cause dents in the personality frames of children which might require therapeutic interventions to mend. The author attempts to identify the toxic components of unhealthy teachers in the educational set-up who deter children's development in the long run, with the help of supportive case studies so that rectifications may be put forward from the desk of the mental health practitioner. This would help children inhale fresh life-enriching air once again and instil positive growth. © Springer Nature Singapore Pte Ltd. 2018.
