sensitivity is what you have now I'm going to explain
to you why it causes let's look at the to structure you have enamel on the top
which has got no sensation that means anything hot cold anything there will be
no sensation because there is no no fibers there the second layer
is dentin which contains some no fibers so if enamel is not there and dentin is
expose then you get that sensation with cold and then there is a heart of the
truth which is pulp and if the sensation goes towards the pulp the
sensation goes towards the pulp then you get pain with hot that
is called pulpitis that is called inflammation in the pulp now what are the
causes of enamel going cause number one is wrong brushing if you are brushing
very hard where there is a hard brush medium brush or soft brush you
are facing wrong brushing that can cause loss of enamel at the junction of gums
and the tooth let's look at this here you can see there is a cavity here where
the enamel is gone because of wrong brushing and once the enamel
goes then the dentin the second layer is exposed and you
get sensitivity the second reason is we all of us got habit of drinking colas
lime juice buying alcohol that is acidic and that erodes the enamel and the
dentin is exposed and when the dentin is exposed patient gets
sensitivity the third reason is attrition when you close your mouth and grind
your teeth at night.
the enamel wears on the chewing surface of the teeth that is
called attrition and enamel goes away and the dentin is exposed then you get the sensation and the next is AB faction what is a fraction when you
grind your teeth left and right left and right which happens at night after some time because of the flexion of the teeth the enamel just comes out at the
junction of the tooth enamel and that is one more reason for
sensitivity of teeth so varying off of enamel a going of enamel is called.
sensitivity the last region of sensitivity is recession of the gums you have all
the good habits but due to age if there is a traumatic bite when you bite
the bite is not correct the recession can take place which
could be due to age also and the recession takes place and the roots are exposed
as you see here if the roots are exposed that dentine in the roots can cause that
sensitivity whether plaque accumulation cause or dentin cause
there's always a confusion about that but the point is very simple for you
people is when the gums receive down the dentin is exposed and that can give
sensitivity I spoke about traumatic so when there's a traumatic bite that
means when you close your mouth only one tooth is touching
very high that can be sensitive on the truth and that diagnosis is very
difficult because to look healthy but you complain of sensitivity and that
sensitivity is due to traumatic bite so these are the different
causes of sensitivity
