An expert has issued a warning over a surprisingly common practice.
From tooth decay to gum disease, and even the spreading of serious illnesses, a chief orthodontist has warned against sharing a toothbrush with your partner, no matter how "tempting" it may be. Whether accidental or intentional, it can lead to your mouth being exposed to a 'whole host of nasty things', the Daily Express reports.
Dr Khaled Kasem, Chief Orthodontist of European leading orthodontic chain Impress said: "Whether intentional or accidental, using someone else’s toothbrush can expose your teeth, gums, and mouth to a whole host of nasty things, especially if they’re not as into their oral health routine as you are. We’d always recommend using your own toothbrush."

Dr Kasem said couples spread bacteria in many ways, from kissing to sharing food but that is "totally normal", however, sharing a toothbrush exposes you to "dangerous bacteria". Mainly because the mix of bacteria in your mouth is "unique to you".
Despite there being hundreds of bacteria in our mouths, some can be harmful, including streptococcus mutans and porphyromonas gingivalis which can all be associated with tooth decay and gum disease and are all found to be "living on toothbrushes".
There is also the risk of brushing mould into your teeth as the longer the brush remains wet, the more likely mould will grow. Another serious concern is the accidental passing of blood after brushing your teeth.
Dr Kasem went on to say it is not uncommon for gums to bleed during brushing but the sharing of toothbrushes could transmit serious illnesses such as hepatitis C. He added the type of toothbrush can also lead to "long-term damage" as different mouths require different types of toothbrushes.
According to the NHS, you should be brushing your teeth twice a day with fluoride toothpaste and floss or use an interdental brush every day to remove food, debris and plaque lodged between your teeth. More information on how to keep your teeth clean and keep up your oral hygiene can be found here.
