The innovative ISSA mini 3 toothbrush effectively cleans teeth, gums, tongue, and cheeks, making it perfect for anyone who prefers a smaller brush head. The hybrid brush head, which lasts up to 6 months, is 10,000 times more hygienic than nylon and gently massages the gums with silicone bristles while effectively removing plaque and tartar deposits with PBT polymer bristles. With the power of Pulse Technology, the ISSA mini 3 lasts up to 265 days on a single USB charge. Additionally, its ergonomic design features a built-in timer that indicates when to switch to a new area of the mouth while brushing. The integrated smiley helpers assist you in maintaining the dentist-recommended 2 minutes of brushing time. They also notify you if you haven't brushed for more than 12 hours. This makes the ISSA mini 3 even more enjoyable for long-lasting, fresh, and intuitive oral hygiene.
