1. Long-term use of the same toothpaste may make oral diseases resistant.
2. Long-term use of abrasives, foaming agents and other ingredients in toothpaste may cause damage to teeth and gums.
3. Although fluoride in toothpaste can prevent dental caries, excessive intake may also cause fluorosis.
4. Some medicated toothpastes may have adverse effects on some people's health, such as oral mucosal injury and oral inflammation.
In order to reduce these hazards, it is suggested to change different types of toothpaste frequently to avoid using the same toothpaste for a long time. At the same time, when using toothpaste, we should also be careful not to overuse it to avoid swallowing toothpaste residue.
