Dentists advise to replace a toothbrush every three months to ensure effective cleaning. This means each of us will use four pieces annually, generating an impressive amount of plastic waste during our lives – not to mention disposable toothbrushes we use while backpacking or staying a night at a hotel. To address this issue and encourage an eco-conscious lifestyle, product designers come up with creative toothbrush designs with sustainability at their core that can keep both our teeth and our plant clean.
