The toothbrush plays a fundamental role in oral health care, as it is responsible for removing food debris, bacterial plaque and microorganisms that can cause cavities, gingivitis and bad breath. However, for it to continue to be effective, it is important to pay attention to when to change it.

The ideal is to change the brush every three months or sooner if the bristles are worn out. “With continuous use, the bristles lose their efficiency in removing bacterial plaque, which can increase the risk of cavities and gum problems”, explains Guilherme Roberto Andrade Lima, Dentistry coordinator at Faculdade Anhanguera.

Don’t wait for the brush bristles to open

Observing the condition of the brush regularly and respecting the recommended replacement period is essential. This attention on a daily basis helps to maintain more efficient oral hygiene and contributes to the health of teeth and gums in the long term. “Many people only change the toothbrush when it is already too open, but the ideal is not to wait for this stage. Prevention starts with habits simple and consistent”, adds the expert.

When to change your toothbrush?

In addition to the time of use, some signs indicate that it is time to replace the toothbrush. Among them are:

1. Open or deformed bristles: indicate loss of cleaning efficiency;
2. Color change in bristles: may signal wear or accumulation of residue;
3. After illnesses: gripescolds and infections can contaminate the brush;
4. Dropping or improper storage: increases the risk of contamination;
5. Heavy use: Those who brush their teeth too hard can wear the item out faster.

Keeping the brush in good condition is essential to guarantee a oral hygiene effective. Furthermore, it is important to store it in a dry and ventilated place, avoiding direct contact with other brushes.
