Are your teeth sensitive?

Posted on Nov 22, 2014 in News | 0 comments

Tooth sensitivity is such a common problem. It is caused when the enamel wears away and the second layer of tooth (dentin) is exposed or when the root surface is exposed. Dentinal structure is tubular and there is fluid in the tubules. The movement of this fluid causes nerve irritation.

It can be caused by several factors:

  • Worn down enamel – brushing hard with a hard toothbrush
  • Grinding (click here for more details )
  • Receding gums – brushing hard, gum disease
  • Cracked teeth
  • Bulimia and acid reflux causing wear of enamel
  • Symptoms can be increased by consuming cold, hot, acidic or sweet foods.
  • Tooth pastes with abrasive ingredients
  • Tartar control and whitening toothpastes
  • Decay

Sensitivity can be described as short sharp pain initiated by certain foods or drinks. It is important to know what starts it and what relieves it. Once the cause is identified, treatment can be initiated. Various measures used to relieve or control it are:

Decrease consumption of acidic foods and drinks (soda)

Brush well and properly with only a soft bristled brush and with a tooth paste that has fluoride in it. Use a prescription tooth paste given by the dentist. Stop using whitening or tartar control tooth paste to see if sensitivity will reduce.

Desensitizing toothpaste – works best if used on a regular basis for long term. Best to use it two or three times a day by rubbing it in or massaging it onto the sensitive teeth and keeping it there as long as possible. It forms a protective layer temporarily and gets worn down by brushing eating etc. That is why it is important to use it long term.

Sealants and Desensitizing agents can be applied in the dental office. A form fitting tray (custom made for your teeth) can also be dispensed to keep the desensitizing agent in close contact with your teeth for a longer duration.

If there is decay, fillings or root canal, if the cavity is too deep, might be needed.
