There are two periods in a human lifespan where tooth sensitivity occurs the most. First, the period between puberty and early thirties is a time of maximum dental growth. It is also along this period that people are usually prone to having sensitive tooth, due to the adaptive changes occurring in the teeth.
Another period of great risk for tooth sensitivity is after your fifties until late adulthood. As a person grows old, the protective layer of the teeth (the enamel) gradually peels off, thereby exposing the inner dentin layers. When this occurs, it is no surprise that older people report tooth pain after exposure to extreme variations in temperature.
2. Excessive Forceful Tooth Brushing
Dentists recommend brushing your teeth at least twice a day. You can follow this religiously or not but this practice does not protect you from having sensitive teeth, if you do not follow correct tooth brushing technique. It is important to remember that proper brushing technique involves delicate (not forceful) brushing strokes.People who tend to brush their teeth forcefully will damage their gums, and peel off the outer layers of their teeth. To prevent having sensitive teeth, make sure that you brush your teeth with mild to moderate force only. If your gums bleed after brushing, better stop brushing too hard, or you will suffer from tooth sensitivity sooner or later.
3. Acidic Food and Drinks
Enamel wear and tear is a gradual process, and you may only feel its effects after many years. Frequent ingestion of acidic beverages (like soda and tea) and food (like citrus fruits, pickles, or tomatoes) promote the wear and tear of the enamel, leaving the dentin exposed.
4. Dental Procedures
The nature of dental treatments (like tooth cleaning, root planing, and teeth whitening) entails that some part of the outer layers of the teeth is scraped off or cleaned. This leaves your teeth exposed for a period of time, and may cause sensitive teeth. In most instances, tooth sensitivity will gradually go away after a few weeks as the teeth heal.
However, some people often rely on teeth whitening treatments that can cause teeth sensitivity when used excessively. Remember to follow the recommended frequency for product use to avoid having sensitive tooth in the long run.
5. Teeth Grinding
Teeth grinding while sleeping can occur as a result of having a poor bite. This involuntary habit can also cause tooth sensitivity if left untreated since it will promote the gradual peeling off of the dentin.
A simple solution to this problem is by wearing a mouth guard. Your dentist can prescribe this device for you.
6. Root Nerve Damage and Gum Disease
The root nerves of the teeth can be damaged if you have severe gum and periodontal disease. This condition further causes the nerves to be easily irritated at the slightest changes in temperature causing sudden tooth pain.
