How Often Should I Be Changing My Toothbrush?

Toothbrushes are an integral part of anyone’s daily routine, and they keep our teeth and gums clean and fresh. Just like kitchen sponges or dishcloths, toothbrushes should be changed regularly over time. This is very important for your hygiene and oral health

Keeping your toothbrush clean

We should always be keeping our toothbrush clean and bacteria-free, as our mouths are breeding grounds for strains of bacteria. It is crucial your toothbrush is maintained for as long as possible and to avoid the spread of bacteria. Inevitably, your toothbrush will need to be changed, but these simple steps should keep it lasting as long as possible:

•    Wash the bristles thoroughly after every use to clean off excess toothpaste and saliva;

•    Keep the toothbrush upright and aerated in order for the bristles to dry more easily;

•    Avoid keeping the toothbrush in an enclosed case between use, as this will breed bacteria quicker.

Why and when to change

If you follow these simple steps, your toothbrush will last approximately 3-4 months, but it is always recommended to stock up in case of an emergency. Aside from the obvious hygiene issues, bristles that are worn and overused will not be at their most efficient for cleaning teeth. You’ll find that worn bristles make it difficult to remove tough bacteria from the surface and between the teeth.

Our mouth can hold more than 1,000 types of bacteria at any one time. Some of these are fine to have – and sometimes crucial for preventing disease – while others should be avoided. If these bacteria are allowed to fester on an old toothbrush, this can cause serious health implications for the user.
