Tooth sensitivity can be frustrating. You may feel a sharp “zing” when drinking cold water, eating ice cream, brushing your teeth, or even breathing in cold air. For some people, sensitivity comes and goes. For others, it becomes a regular problem that affects daily life.
Sensitive teeth happen when the inner layer of the tooth, called dentine, becomes exposed or irritated. Dentine contains tiny channels that connect to the nerve of the tooth. When cold, heat, sweetness, or pressure reaches these channels, it can trigger discomfort.
There are several reasons teeth may become sensitive. One common cause is gum recession. When gums move away from the tooth, the root surface can become exposed. This area is not protected by enamel in the same way as the crown of the tooth, so it can feel much more sensitive.
Another common cause is enamel wear. Brushing too hard, using a hard toothbrush, grinding your teeth, or consuming acidic drinks frequently can gradually wear down enamel. Fizzy drinks, citrus, sports drinks, and wine can all contribute to acid erosion over time.
Tooth decay, cracked teeth, leaking fillings, or recent dental treatment can also cause sensitivity. This is why it is important not to assume all sensitivity is “normal”. If pain is lingering, worsening, or only affecting one tooth, it is worth booking a dental check-up.
For mild sensitivity, switching to a sensitivity toothpaste can help. Use it twice daily and avoid rinsing heavily after brushing so the active ingredients stay on the teeth longer. A soft toothbrush and gentle brushing technique are also important. Avoid scrubbing sideways at the gumline, as this can make recession and sensitivity worse.
If you grind your teeth at night, your dentist may recommend a custom night guard to protect enamel and reduce pressure. If acid erosion is a factor, small changes such as drinking water after acidic drinks and avoiding brushing immediately after acidic foods can help protect the enamel.
Professional treatment depends on the cause. Your dentist may suggest fluoride varnish, bonding, repairing a filling, treating decay, or managing gum issues. The right solution starts with identifying the reason for the sensitivity.
