Experiencing sudden sharp or lingering sensations of hot and cold in your teeth can be uncomfortable and concerning. Many people encounter this issue at some point, but what causes these temperature sensitivities? Understanding the reasons behind hot and cold sensations in teeth is the first step toward protecting your oral health and receiving the right treatment.
At All In One Dental, we frequently help patients identify the root causes of tooth sensitivity and recommend effective professional solutions for long-term relief. This blog post explores the common reasons why you might feel hot or cold sensations in your teeth, the symptoms to watch for, and why it’s important to see your Spearwood dentist for expert care.
What Causes Hot and Cold Sensations in Teeth?
Temperature sensitivity in teeth often occurs when the inner layers of your tooth — the dentin and nerves — become exposed or irritated. Normally, your enamel and gums act as protective barriers, insulating the nerves from extreme temperatures. When these barriers are compromised, hot or cold stimuli can trigger discomfort or pain.
Here are the most common causes of temperature sensitivity in teeth:
1. Tooth Enamel Erosion
Your tooth enamel is the hard outer layer that protects teeth from damage. Over time, enamel can wear down due to:
- Excessive brushing with hard bristles or abrasive toothpaste
- Acidic foods and drinks like citrus fruits, soda, and wine
- Acid reflux or frequent vomiting (which exposes teeth to stomach acid)
When enamel thins or erodes, the sensitive dentin underneath becomes exposed, making your teeth vulnerable to hot and cold sensations.
2. Gum Recession and Exposed Tooth Roots
Gum recession occurs when the gums pull away from the teeth, exposing the roots. Unlike the enamel-covered crown of the tooth, roots are covered by cementum, which is much softer and more sensitive.
Gum recession can result from:
- Aggressive tooth brushing
- Gum disease (periodontitis)
- Aging
- Tobacco use
Exposed roots allow temperature changes to easily irritate the tooth nerves, causing sharp hot or cold sensitivity.
3. Dental Cavities and Tooth Decay
Tooth decay causes holes in the enamel that allow stimuli to reach the inner nerve tissues. Cavities often start small but grow if untreated, increasing sensitivity and eventually leading to pain, infection, or abscess.
4. Cracked or Fractured Teeth
Cracks in teeth can develop from trauma, grinding, or biting hard foods. These cracks create pathways for hot and cold sensations to penetrate deeply and irritate nerves. Sometimes the sensitivity may come and go or worsen with temperature changes.
5. Recent Dental Procedures
After dental work such as fillings, crowns, teeth whitening, or deep cleaning, it’s common to experience temporary hot or cold sensitivity. This usually subsides within a few days to weeks as the tooth heals.
6. Tooth Grinding (Bruxism)
Grinding or clenching your teeth puts pressure on enamel and can cause microfractures or gum recession. This damage exposes sensitive areas, increasing temperature sensitivity.
7. Sinus Infection or Pressure
Believe it or not, sinus infections can cause referred pain or sensitivity in the upper teeth. The roots of upper teeth are close to the sinus cavities, so pressure or inflammation in the sinuses may cause tooth discomfort, including sensitivity to hot or cold.
Symptoms to Watch For
If you have tooth sensitivity, you may notice:
- Sudden sharp pain when drinking hot or cold beverages
- Lingering ache after consuming cold or hot food
- Sensitivity triggered by sweet or acidic foods
- Discomfort when brushing or flossing
- Sensitivity when breathing in cold air
If these symptoms persist or worsen, it’s important to visit a dentist promptly to diagnose the cause and prevent further damage.
