Sensitivity to cold air or liquid is USUALLY caused by an exposed root surface at the gumline, mostly on the outside, or cheek side of the tooth. When the gumline recedes, even a tiny bit, the root becomes exposed and it is NOT covered by protective enamel. Therefore the nerves of the tooth are more accessible. So with a drink of cold water, a shot of pain occurs, causing the avoidance of cold liquids, or the re-routing of them to the other side. Applications of fluorides, remineralizing pastes, or special resins applied in the dental office, are the best ways to combat this “naked root pain”. Other ways include chemical applications through the use of toothpastes like Sensodyne.
Other types of sensitivity such as pain upon biting, might be caused by a crack in the tooth, or filling, an abscess, or a “high” filling or crown. Read more about “Cracked Tooth Syndrome” or “What Is An Abscess” on our website or ask for a handout.
Pulpitis, or inflammation of the dental pulp (nerve tissue and blood supply) can also cause sensitivity. Pulpitis is caused by “insults” to the pulp such as decay and the dental work done to repair the decay.
