Your toothbrush is an essential tool for maintaining good oral hygiene, but many people overlook the importance of replacing it regularly.

Knowing when to replace your toothbrush can help you maintain a healthy mouth and prevent various dental problems.

Why should you replace your toothbrush?

Over time, toothbrushes wear down and become less effective at cleaning your teeth. The bristles become frayed and distorted, reducing their ability to effectively remove plaque and food particles.

Additionally, toothbrushes can harbor bacteria, especially if they are not stored properly.

Using an old toothbrush can spread germs and lead to infection or other oral health problems.

Choosing the right toothbrush

According to Dr Bibhakar Ranjan, a Seychelles-based dental surgeon, one should buy one that suits their personal preference, health condition, age and usage, and most importantly, one that is comfortable to use.

There are 4 different types of toothbrush bristles: soft, extra soft, medium and hard.

Dr Ranjans said soft or extra-soft bristles should be used by people who have better-aligned teeth and less stain and plaque buildup.

“However, some people have more stains and plaque on their teeth, possibly due to incorrect brushing or frequent eating. They may need to use a toothbrush with medium or hard bristles,” the expert said.

Irrespective of the type of bristle toothbrush you use, it is important to always follow the correct brushing technique to get better results.

Dr. Ranjan said that many times, the wrong way of brushing and the habit of brushing vigorously causes erosion of tooth enamel, which can lead to severe tooth sensitivity and pain.

In addition, you should choose a flexible toothbrush neck, as it can “reach far back in the mouth and clean areas of the teeth that are not easily accessible.”

Select a handle that has a good grip and is comfortable to hold.

When should you replace your toothbrush?

Replacing your toothbrush regularly is a simple yet important step in maintaining optimal oral health.

By changing your toothbrush every three to four months, or sooner if necessary, you can ensure that your brushing is effective and your mouth stays healthy.

Dr Ranjan advised to keep an eye on the condition of your toothbrush and if it shows any wear or marks after recovering from an illness, do not hesitate to replace it.

He said, “We all should check our toothbrush before brushing to see if the condition of the bristles is good or bad. Bad bristles can not only damage our tooth enamel but also harm our gums, causing gum bleeding or sensitive teeth.”

If you are sick, change your toothbrush as soon as you recover. According to dentist Dr. Shuchi Singh, you should also change your toothbrush if it has come in contact with a sick family member.

With proper care and timely replacement, your toothbrush will remain a valuable ally in your daily oral hygiene routine.
