Sensitivity can be a
result of many different sources.
One frequent cause is the
type of toothpaste used. Toothpastes that have tartar
control or whitening agents may cause teeth to react to hot
or cold stimulation. Substituting a toothpaste for sensitive
teeth, either prescribed by your dentist or over-the
counter, may help.
Brushing too hard or using a
hard-bristled toothbrush and
grinding or clenching your teeth may
wear away enamel in the same way.
Movement of gums away from the tooth
due to periodontal disease or other gum disease will expose
the root surface and in crease sensitivity. Inflamed and
sore gum tissue may also cause sensitivity due to the loss
of supporting ligaments which exposes the root surface.
The presence of plaque on the root
surfaces can cause sensitivity. Additionally, chipped,
cracked or broken teeth may fill up with bacteria from
plaque and enter the pulp causing an inflammatory reaction
that causes pain.
Proper brushing techniques and regular
dental checkups are your best defense against tooth
sensitivity.
