Question: what is the difference between oral b 2000 and 2500?
Answer: The only real difference is the colour. The Oral-B Pro 2000 is a pale blue (can also come in a vibrant pink), the Oral-B Pro 2500 is black (can also come in vibrant pink) and the Oral-B 3000 which is a dark blue. Out of the three colours, the Oral-B Pro 3000 dark blue appeals to me the most.
