White spots on people’s teeth are caused by bacteria penetrating the tooth’s enamel layer. These bacteria cause cavities and decay. If left untreated, they may lead to severe problems, including pain, infection, and even loss of the tooth.
The first action to prevent this problem is to brush your teeth twice daily using fluoride-free toothpaste. You should also floss at least once per day. To prevent further damage, visit your dentist regularly for checkups and cleanings.
