scary shari asked: I understand why extreme temperatures like hot or cold can bother sensitive teeth, but I don’t understand why sweet foods touching a tooth can cause sensitivity? For example, a Hershey bar isn’t hot or cold — it’s just an inert piece of chocolate. So why do I get a sharp painful feeling when 1 or 2 of my molars chew the chocolate?
For the record, my dentist checked the area in question. There are no cracks in those teeth & no decay in their fillings — he looked with his eyes PLUS took x-rays to be certain.
He said the teeth are probably just sensitive due to my nighttime bruxism (tooth clenching and/or grinding), or perhaps also because I used to use a somewhat abrasive whitening toothpaste. (I now use Sensodyne and it’s definitely helping those teeth as well as ALL my teeth!)
What I don’t understand is why SWEET causes me more pain on the affected molars than cold or hot? What does sweet do that temperature does not? (rhyme not intentional! *grin*)
Green1808 reminded me that I too have heard some people’s sensitive teeth are in fact caused by (or worsened by) receeding gums. HOWEVER, that’s not the case with my gums — I’m thankful to say!
But it’s important for others to know that it might be the case for them.
Actually, it’s always good to have a dentist rule out all the “bad stuff” first, like mine did (i.e. receeding gums, cracked fillings or teeth, or hidden cavities). OUCH! :[ Almost makes my teeth hurt just thinking about this stuff!
