1. Use less toothpaste, just squeeze out a little bit and add some water to your toothbrush.

2. After each use of toothpaste, blow out any residual water from the cap to avoid moisture from getting into the toothpaste and causing it to spoil.

3. Refrigerate your toothpaste, as cold temperatures can slow down deterioration and aging.

4. Avoid exposing toothpaste to sunlight or high temperatures, which can cause it to deteriorate.

5. Use a spoon or special squeezer to squeeze out the toothpaste, and avoid direct hand contact with the toothpaste.

6. Store toothpaste in a dry, ventilated, cool environment.

7. Replace your toothbrush regularly and choose the type of toothpaste that is suitable for your oral health according to your dentist's recommendations.
