Maybe you notice it when you sip on your iced latte in the morning or when indulging in a milkshake with your hamburger at dinner. For some reason, your teeth have become sensitive to cold foods and drinks. Such a sensitivity can be quite uncomfortable and even painful. It’s left you wondering what causes it and what you can do about it.
What Causes Tooth Sensitivity?
Tooth sensitivity to cold is often caused by exposed dentin, a layer of the tooth beneath enamel that is more sensitive to temperature changes. This exposure typically happens when the protective enamel layer wears down, exposing the dentin tubules that connect to nerves inside the tooth. Other causes include receding gums, tooth decay, and aggressive brushing.
Enamel Erosion
The outer layer of your teeth, enamel, acts as a protective shield. Daily wear and tear, acidic foods, aggressive brushing, or even teeth grinding can gradually erode this enamel. When enamel wears away, the dentin beneath becomes exposed, leading to sensitivity to cold.
Receding Gums
When gums pull away from the teeth, it exposes the roots, which are not protected by enamel. This exposes the sensitive dentin, making teeth more sensitive to cold and hot temperatures.
Tooth Decay
Untreated tooth decay can erode the enamel and create cavities, exposing the dentin and allowing cold temperatures to stimulate the nerve endings directly.
Aggressive Brushing
Brushing too hard or using a toothbrush with stiff bristles can also wear down the enamel and expose the dentin, leading to sensitivity.
Periodontal Disease
Periodontal disease can lead to gum recession, exposing the tooth roots and making them sensitive to cold.
Other Causes
Tooth whitening products, certain dental procedures, and even some sinus infections can also contribute to tooth sensitivity. Speaking with your dental care provider about the right teeth whitening products for you and how dental procedures may impact your teeth is imperative.
Frequently Asked Questions about Tooth Sensitivity
What Are Some Remedies and Treatments for Tooth Sensitivity?
Several home remedies and professional treatments can help manage tooth sensitivity. Using a desensitizing toothpaste containing fluoride, stannous fluoride, or potassium nitrate can help strengthen enamel and reduce discomfort. Salt water rinses can reduce inflammation and promote healing, while gentle brushing with a soft-bristled toothbrush helps avoid further irritation. It's also essential to limit acidic foods and beverages to prevent additional enamel erosion. In more severe cases, a dentist may recommend desensitizing agents, fillings, sealants, or crowns to protect the teeth. If teeth grinding is contributing to the problem, wearing a custom-fitted mouth guard can help prevent further enamel wear.
When Should I Seek Professional Help for Tooth Sensitivity?
You should seek professional dental care if your tooth sensitivity is severe or persistent, especially if it begins to interfere with daily activities like eating or drinking. Immediate attention is also necessary if sensitivity is accompanied by other symptoms such as fever, swelling, or pus, which could indicate an infection. If you suspect a cracked tooth or tooth decay, it’s important to schedule a dental visit right away. Left untreated, underlying issues can worsen and may require more extensive treatment.
