Tooth Sensitivity: Causes, Prevention, and Treatment

Tooth sensitivity is one of the most common dental complaints there is, affecting a great many people. It shows up as a sharp, sudden pain in response to hot, cold, sweet or acidic foods and drinks, the wince at a cold drink or a spoonful of ice cream. If that’s familiar, here’s a practical look at the causes, how to prevent it, and what can help when it lingers.

Understanding the mechanism first makes everything else easier to follow.

What causes tooth sensitivity

Sensitivity arises when the protective outer layers of the tooth, enamel and cementum, wear away and expose the dentin beneath. Dentin is riddled with microscopic tubules leading to nerve endings, so once it’s exposed, hot, cold and sweet stimuli can trigger that familiar jolt.

Several things lead to that exposure: enamel erosion from acidic foods, aggressive brushing or grinding; gum recession that uncovers the tooth roots; cracked or chipped teeth; recent dental work such as whitening or fillings; and decay or cavities. Often more than one factor is in play.

Preventing and minimising it

Plenty can be done to prevent sensitivity or keep it in check. Use a soft-bristled brush and a gentle technique to avoid wearing at enamel and gums, and choose a toothpaste made for sensitive teeth, which helps block the exposed nerve endings over time.

Diet matters too: go easy on highly acidic foods and drinks, or sip them through a straw to limit contact with your teeth. If you grind at night, a mouthguard can protect against the wear that follows. And keeping up good daily hygiene plus regular check-ups rounds out the prevention side nicely.

Treatment options when it persists

If sensitivity sticks around despite your best efforts, it’s worth seeing your dental team, who can look at what’s driving it and suggest suitable options. These may include applying fluoride gel or varnish to strengthen enamel and ease sensitivity, or dental bonding to cover exposed dentin or roots.

In more involved cases, where decay or infection is the cause, root canal therapy may be discussed, and where gum recession is to blame, a gum graft can cover exposed roots. Which of these fits depends entirely on the underlying cause, which is exactly why an individual assessment matters.
