Molars make up most of teeth pain: dental study

TAIPEI, Taiwan — Molars make up the majority of sensitive, painful teeth while improper brushing is the root cause of most toothaches, according to a recent dental study.

In findings revealed by the Taipei Medical University, which tested nearly 800 patients, nearly 70 percent of toothaches were found in molars while inadequate brushing of teeth is the main cause of tooth sensitivity.

In the study, a total of 47 dentists sprayed the mouths of 796 people aged 16 to 83 with compressed, cold air to assess their teeth soreness and sensitivity. Out of the 1,224 identified sensitive teeth, 38 percent were premolars, 29 percent molars, while incisors and canine teeth made up 18 and 14 percent, respectively.

Around 39 percent of sensitive teeth can be attributed to the way they are brushed, especially around the premolars, which as transitional teeth, are often over-brushed and easily abraded. Around 16 percent was due to periodontal disease and 21 percent, gingival recession. Dental surgery or tooth whitening procedures can increase tooth sensitivity, the study found.

Dentists can ameliorate tooth sensitivity by using high concentrations of fluoride and arginine and other ways as fillers. Toothpaste for sensitive teeth is also available on the market.
