After about three months or so, it is important to keep changing your toothbrush. We are going to take a look at some of the reasons why.
Bacteria And Germs
This is the primary reason why you should be changing your toothbrush every three months. Research and a lot of studies show that the toothbrush can be a home to as many as ten million bacteria. You can take care of your toothbrush by always rinsing it or sanitizing it but at the end of the day you are going to have to replace it because with time the bristles become home to a lot of germs and bacteria and this is not good for your teeth and generally for your health
Bent Bristles Do Not Brush Well
Having a bad toothbrush beats the purpose of having a toothbrush in the first place. The bristles of a toothbrush become less subtle and start to bend after being used for a long time. When this happens, you will find that they are not as effective as they are supposed to be in ridding your teeth of plaque and food particles. They do not reach in between your teeth and gums, and this will prevent you from having healthy teeth and gums because that is an avenue for food particles to be left in between your teeth even after brushing leading to cavities. This can be prevented by changing your toothbrush every three months.
Threat Of Re-infection
It is normal that at some point in time, you will be infected with the flu or have a cold. Even after you get better, you will find that you are at risk of being infected again if you keep using the same toothbrush. This is because germs and bacteria tend to live in the bristles. Even if three months are not over since the last time you replaced your toothbrush, if you have had a cold, it is recommended that you dispose it and get yourself a new toothbrush. Do this every time you get sick or infected.
When a toothbrush is first being made, all of the bristles are usually of the same size, but they are made in little domes that are soft to prevent them from being abrasive. After using your toothbrush for a while, it gets back to how it was before the bristles were made into soft domes and they become rough, and it is possible for your gums and enamel to be scrapped off.
