A sharp twinge from something hot or cold is common — but it isn't something you have to just live with.
Underneath the hard outer layer of a tooth is a softer layer connected directly to the nerve. When that outer layer wears thin, or a gum recedes and exposes the tooth's root, hot, cold, or sweet foods can reach the nerve and cause that quick, sharp pain.
The cause varies: a cavity, a cracked tooth, a worn filling, gum disease, or a receding gumline can all produce the same symptom. Because the right treatment depends on which one is at work, sensitivity is worth having looked at rather than managed on your own with a different toothpaste.
