Have you noticed your teeth are more sensitive as the weather gets colder? It’s a common complaint. During colder weather, your teeth can contract slightly, potentially causing microcracks that slightly open whenever you bite down, and which can allow unwanted sensations to penetrate your tooth nerves.
Usually, your teeth are protected by tooth enamel, which covers the dentine underneath. Unlike enamel, dentine consists of microscopic tubules which can easily transmit the sensations of hot and cold to your tooth nerves. There are other reasons why your teeth could feel more sensitive and which include:
- Overusing tooth whitening agents that can wear down your enamel. If this is a problem, stop using the product immediately and ask us for help and advice.
- Tooth decay, as an untreated cavity or failing filling will allow cold sensations to penetrate the tooth easily.
- Periodontal or gum disease can expose your tooth roots which aren’t covered with protective tooth enamel, causing sensitivity.
- Brushing your teeth too vigorously can literally wear down your enamel.
- Bruxism or clenching and grinding can crack and wear down your teeth.
If you do have tooth sensitivity, it’s best to have a checkup in case you require dental treatment. Otherwise, using toothpaste for sensitive teeth can help.
