BioBleach Soft 120mm Circle x 1mm 20/BX is a dental product used for teeth whitening. It contains a soft and flexible tray made of a biocompatible material that is comfortable for patients to wear during the whitening process. The tray is designed to be used with a teeth whitening gel or paste that is applied to the tray and then inserted into the patient's mouth. The BioBleach Soft tray conforms to the patient's teeth, allowing the gel or paste to cover the teeth evenly and provide consistent whitening results. The 120mm Circle x 1mm size is ideal for patients with different mouth sizes and shapes.
