Importance of brushing

• Dentists around the globe recommend children and
  adults brush their teeth twice a day. This is to
  avoid plaque deposition and bacterial growth in
  their mouths. The human digestive system contains
  a lot of bacteria and microbes that aid in
  digestion. However, excessive microbial growth
  can turn out to be harmful and sometimes fatal to
  human health. In the case of bacteria in the
  mouth, these organisms feed on the food that we
  consume and produce acid as an end product. These
  acids are corrosive and hence can damage the
  enamel on your tooth, resulting in cavities.
  Using a pea-sized amount of a nano-hydroxyapatite
  toothpaste can generally ward off the bacteria in
  your mouth. 
• To ensure additional oral care, it is better to
  use products such as mouthwashes, dental floss,
  tongue cleaners and so on.

Importance of Toothbrush Bristles

• Toothbrush bristles are a key component of a
  toothbrush. There are different types of
  toothbrush bristles available today. Some of the
  toothbrushes have hard bristles, while a few
  others have soft bristles. In general
  soft-bristled toothbrushes are preferred over
  hard ones. This is to avoid damaging your gums.

Why do You Need to Change Toothbrush Bristles

• Bristles both in the case of manual and electric
  toothbrushes tend to get frayed after a limited
  period. And a frayed and old toothbrush has
  limited performance when compared to a new one.
  To ensure maximum efficiency, make sure you
  change the bristles in your electric toothbrush
  or the brush itself in the case of a manual
  toothbrush. The general recommended period for
  changing bristles is 3 months. This is
  recommended by experts at the American Dental
  Association. However, most people tend to leave
  these little things uncared. There are a few
  toothbrushes that come with features such as
  colour changing bristles that act as an indicator
  for you to change your brushes or brush heads. 
• In addition, most doctors also suggest changing
  your toothbrush or bristles after you have
  suffered an infection such as flu or fever. This
  is just to avoid reinfection from the microbes
  housed in your toothbrush. It is important to
  keep the bristles in your brush heads as clean as
  possible. Wash your bristles in clean water after
  every brush to avoid bacterial multiplication in
  your toothbrushes.
