What is Tooth Sensitivity and Why Does it Hurt?

It’s that twinge or stab of pain you feel when you’re trying to eat some ice cream, or enjoy a coffee, or even when you’re just brushing your teeth.

Tooth sensitivity, also called dentinal sensitivity, affects nearly one out of three adults.

Symptoms may surface as early as your mid 20’s.

Why does it hurt?

Pain occurs when the enamel (the protective coating on your teeth) has worn away or when your gum tissue recedes, exposing the inner layer called dentin.

Without the protective layer of enamel or gums, painful sensations can travel more easily through the tooth to its sensitive nerve centre.

Erosion starts with the everyday wear and tear of chewing and brushing and can worsen when dietary acids found in citrus fruits and drinks and carbonated beverages accumulate on your teeth, softening the enamel. Or you may be one of those people whose tooth enamel is just naturally thin in places.

How to prevent and treat tooth sensitivity?

1) Brush 2 x day with Sensodyne toothpaste or other brand that has anti - sensitivity agent built-in
2) Maintain good oral hygiene
3) Have regular professional cleanings and check-ups
4) In worst case scenarios your dental professional  may recommend to have a filling placed on the exposed root  surface
