Did you know that the cold air of winter can have an impact on your dental health? Believe it or not, being outside in cold, sometimes sub-zero temperatures, can affect tooth enamel. Here's what you should know and how you can protect your smile from winter's effects.
The Science of the "Deep Freeze"
Being outside in the cold and then going inside to the warmth can cause "thermal shock" to the enamel of your teeth. Tooth enamel expands and contracts with temperature changes, and moving in and out of cold temperatures exacerbates this. When that happens, it can result in a few different damaging situations for tooth enamel:
- Enamel Erosion — This is when enamel wears away, leaving your teeth more susceptible to decay, sensitivity, or damage.
- Gum Recession — Cold air can cause tooth clenching and grinding (bruxism), which contributes to gum recession.
- Problems with Restorations — Dental fillings, especially older metal ones, can pull away from the tooth during expansion and contraction, leaving it susceptible to bacteria and decay reentering it.
Furnaces produce dry, forced-air heat, which can reduce saliva production in your mouth, a condition known as dry mouth. Dry mouth contributes to problems like tooth decay and cavities since saliva is a natural protectant for your teeth. Cold air can also cause mouth breathing, which can contribute to dry mouth.
