<Hot and cold sensation in tooth reason and cure>

 

 

Is the taste of frozen dessert or a sip of hot coffee sometimes a painful experience for you? Does brushing or flossing make you wince occasionally? If so, you may have sensitive teeth.
Possible causes include:

Tooth decay (cavities)
Fractured teeth
Worn fillings
Gum disease
Worn tooth enamel
Exposed tooth root

 a layer of enamel protects the crowns of your teeth. Under the gum line a layer called cementum protects the root . Underneath both the enamel and therefore the cementum is dentin.
Dentin is a smaller amount dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals).

Whenever there is  dentin cannot cover with enemal or cementum  these tubules allow heat and cold or acidic or sticky foods to succeed in the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.

Sensitive teeth can be treated. The type of treatment will depend upon what's causing the sensitivity. Your dentist may suggest one among a spread of treatments:
Desensitizing toothpaste. in these type of toothpaste have compounds that can reduce transmission of sensation from the tooth surface to the nerve
Fluoride gel. An in-office technique which strengthens enamel and reduces the transmission of sensations.
A crown, inlay or bonding. These could also be wont to correct a flaw or decay that leads to sensitivity.
Surgical gum graft. If gum tissue has been lost from the basis , this may protect the basis and reduce sensitivity.
Root canal. If sensitivity is severe and protracted and can't be treated by other means, your dentist may recommend this treatment to eliminate the matter .
Proper oral hygiene is that the key to preventing sensitive-tooth pain. Ask your dentist if you've got any questions on your daily oral hygiene routine or concerns about tooth sensitivity.
