Italians live by the rule of 15: 1  Use coffee beans within 15 days of roasting. 2  Use ground coffee within 15 minutes of grinding. 3  Drink coffee within 15 seconds of brewing.
The good news is that teeth (and bones) are able to heal themselves in a process called remineralization. Basically, specialized cells in the center of the tooth are able to regenerate dentin, the layer of tooth just under the enamel, and the enamel can then properly remineralize from the outside.
How can I tighten my loose teeth? A: For an injured, slightly loose tooth, eat soft foods and avoid chewing with the tooth for several days while it tightens on its own, explains Plaza Drive Dentistry. A tooth splint helps tighten a tooth that does not heal by itself, notes Advanced Dental Care of Austin.
