Caution should be taken with the avulsed tooth to place it carefully in liquid and not rinse it off.

Roll the brush slowly over the teeth. Replace and repeat 5 times or more. Overlap strokes. •the bass method- Place the brush at a 45 degree angle to the tooth apex. Apply gentle pressure so bristles enter sulcus. Use a vibratory motion (horizontal jiggle) to activate bristles. Lift brush and repeat in next area, useful to remove plaque and debris from gingival sulcus. Useful for healthy tissue. •charters method- Place brush at a 45 degree angle towards occlusal/incisal plane. Move brush in several small rotary motion keeping bristles in contact with the gingival margin.
