Everybody knows the basic rule regarding oral care – to brush one’s teeth at least twice per day.
However, there is another important issue that is frequently neglected – how often do you need to replace your toothbrush or head of an electronic toothbrush?
There are many reasons why using a toothbrush after its expiration date is not only ineffective but also hazardous to your oral health.
Let us explore what happens to our toothbrushes with time and why the latest innovations can make your life easier and healthier.
How often is often enough?

According to the ADA and the CDC, your toothbrush or electric toothbrush head needs replacement after 3 to 4 months.
However, this is just the minimum. There are various reasons why you need to retire your brush earlier than that:
-
Frayed or spread-out bristles: If the bristles are bent outwards and no longer stiff, the toothbrush is done for good.
-
After an illness: Got over the flu, a viral infection, or a nasty case of strep throat? Get rid of the old toothbrush – germs may linger in the bristles and infect you again.
-
Contamination: This occurs if your toothbrush falls to the floor, gets jostled around in an uncovered case, or brushes against someone else’s toothbrush.
The risks of using an old toothbrush
When looking for savings, one might think to extend the lifetime of their toothbrush head; however, there are two primary risks that you expose yourself to through such actions:
1. You create a hot spot for harmful bacteria
There are countless microorganisms living in your mouth.
With each brushing, they make their way from your mouth to the brush bristles.
Over 90-120 days of being stored in a moist environment, the bristles become colonized with bacteria and fungus, which you re-introduce into your body with each brushing session.
2. Lowering of effectiveness of brushing (Plaque trapper)
Toothbrushes are created so that their bristles remain straight up to help remove plaque from the teeth and get inside interdental spaces.
Research by Healthline indicates that already after 40 days of using the brush, bristle flaring becomes noticeable, thus, the brush loses its ability to remove plaque effectively.
With soft bristles, you can only move plaque from one spot to another.

Innovative in its design, the Wave Pro combines dental techniques with state-of-the-art technology.
The advantages of the Wave Pro by Laifen in oral health:

How to extend the life of your brush heads?
Although you have to continue to replace your Laifen Wave Pro brush heads after every 3 months for ultimate hygiene purposes, there are ways that you can keep them sparkling clean when using them:
Avoid excessive pressure
The Wave Pro uses a servo motor, and by applying excessive pressure, bristles get splayed easily.
Rinse properly
After every brushing session, rinse your brush heads using warm water, spreading bristles apart so that any accumulated toothpaste gets rinsed off.
Keep in upright positions in the open air
You should never keep your toothbrush in closed containers permanently. Air drying in an upright position is the best method of fighting bacteria.
Your teeth deserve the best protection
Monitor your calendar and bristle wear, and along with your hygiene habits, combine them with innovative technology in Laifen Wave Pro for cleaner smiles.
Conclusion
Having a new toothbrush is essential for having an attractive smile. You don't need to wait until the bristles become worn out.
Maintain a clean environment within your mouth by replacing your brush head every three months, and enhance your experience by combining it with the superior technology of the Laifen Wave Pro.
