Regular dental check
The toothbrush should change every three months. Microbes on the wet brush are easy to clean. You will benefit from using at least 3 brushes at the same time. You should keep your toothbrush apart from the brush of others.
In the bathroom, in your wallet, etc. you should keep signs or symbols that motivate yourself about oral care. It is important for your dental health to go to check every 6 months.
