On a good day , your teeth can chew through toughened steak and split hard candy into pieces without you feeling a affair . But sometimes , something as simple as slurp a frosty milkshake can send a shock through your tooth that feels even more painful than stub your toe .
According toLive Science , that sensitivity is a defense mechanism we ’ve developed to protect damaged teeth from further injury .
“ If you eat up something too live or chew something too inhuman , or if the tooth is worn down enough where the underlying tissue underneath is let out , all of those things do pain , ” Julius Manz , American Dental Association spokesperson and director of the San Juan College dental hygienics programme , told Live Science . “ And then the pain make the person not to use that tooth to seek to protect it a little bit more . ”

Teethare made of three layers : enamel on the outside , pulp on the inside , and dentin between the two . flesh , which contains blood vessels and brass , is the layer that in reality feels pain — but that does n’t stand for the other two layers are n’t demand . When your enamel ( which is n’t animated and ca n’t feel anything at all ) is worn down , it exhibit the dentin , a tissue that will then allow especially live or cold substances to stimulate the mettle in the mush . flesh ca n’t sense temperature , so it render just about every stimulus as painful sensation .
If you do have a toothache , however , pulp magazine might not be the ( only ) perpetrator . The periodontic ligament , which connects teeth to the mandibular bone , can also feel pain . As Manz explicate , that tender touch the great unwashed sometimes get because of an orthodontic intervention like suspender is normally coming from the periodontal ligament rather than the pulp .
