Tooth sensitivity, often described as a sharp, sudden pain that shoots deep into the nerve endings of your teeth, is a common dental concern affecting many individuals worldwide. This discomfort can be triggered by various stimuli, including hot or cold beverages, sweet or acidic foods, and even cold air. But what causes tooth sensitivity, and more importantly, what can you do about it?
Causes of Tooth Sensitivity
Enamel Erosion: The outermost layer of your teeth, known as the enamel, acts as a protective shield. Over time, aggressive brushing, acidic foods, or frequent consumption of carbonated drinks can wear down this protective layer, exposing the underlying dentin. Dentin contains tiny tubules that lead to the tooth’s nerve, and when exposed, can result in sensitivity.
Gum Recession: Gums play a crucial role in protecting the roots of our teeth. However, factors like gum disease or aggressive brushing can cause the gums to recede, exposing the roots. Unlike the crowns of our teeth, the roots don’t have enamel to protect them, making them more susceptible to sensitivity.
Tooth Grinding: Some people have a habit of grinding their teeth, especially during sleep. This can wear down the enamel and lead to sensitivity.
Dental Procedures: Sometimes, after dental treatments like fillings, cleanings, or teeth whitening, patients might experience temporary sensitivity.
Managing and treating tooth sensitivity
Desensitising Toothpaste: There are several toothpastes available in the market formulated specifically for sensitive teeth. They contain compounds that help block the transmission of pain signals from the tooth’s surface to its nerve.
Soft-bristled Toothbrush: Switching to a soft-bristled toothbrush can prevent enamel erosion and gum recession caused by aggressive brushing.
Fluoride Application: Your hygienist or dentist can apply fluoride to the sensitive areas of your teeth. This strengthens tooth enamel and reduces pain.
Dietary Changes: Limiting acidic foods and drinks can prevent enamel erosion. If you do consume them, it’s advisable to use a straw to minimise contact with your teeth and rinse your mouth with water afterwards.
Mouthguards: If you grind your teeth, consider getting a mouthguard. This protective device can prevent tooth damage from grinding.
Root Canal: If sensitivity is severe and persistent, and other treatments aren’t effective, your dentist might recommend a root canal. This procedure treats problems in the tooth’s soft core, or dental pulp, eliminating the issue at its source.
Regular Oral Hygeine & Dental Check-ups: Regular visits to the oral hygienist & dentist can help identify and address potential causes of sensitivity before they become severe.
Prevention is key
While there are treatments available for tooth sensitivity, prevention is always the best approach. Maintain good oral hygiene practices, including brushing twice a day with fluoride toothpaste, flossing daily, and visiting your oral hygienist regularly. Avoiding acidic foods and drinks, using a soft-bristled toothbrush, and addressing any teeth-grinding issues can also go a long way in preventing sensitivity.
In conclusion, tooth sensitivity is a common but treatable condition. By understanding its causes and taking proactive measures, you can enjoy your favourite foods and drinks without the fear of that sharp, sudden pain. If you’re experiencing sensitivity, it’s essential to consult with your oral hygienist or dentist to determine the best course of action tailored to your needs.
Remember, a pain-free smile is a happy smile!
