The tooth is the only part of the human body that can’t repair itself
Can a tooth repair itself?
It depends. It is possible for a tooth to repair itself if the damage is minimal. For example, if a tooth with a crack on the outer level and a small fracture line that does not cause pain may repair itself over time. The healing process is known as remineralization and refers to the minerals in our mouths. Saliva does quite a lot when it comes to keeping our mouths healthy and can help to rebuild up the enamel on the cracked tooth so it is strong and protective once again.
In order to help the remineralization process, it is necessary to make good food choices (reducing one’s sugar intake is highly recommended) and use a fluoride toothpaste.
