Why Do Teeth Become Sensitive?
Teeth are protected by a strong outer layer called enamel. When the enamel wears down or the gums recede, the softer layer underneath, known as dentin, becomes exposed. Dentin contains microscopic tubules that connect directly to the nerves, which is why triggers like cold, hot, sweet, or acidic foods can cause pain.
Several factors can speed up this process. Drinking acidic beverages such as coffee, soda, or citrus juices, having acid reflux disease, and brushing your teeth too aggressively can all wear down enamel. Gum recession caused by gum disease can also expose the tooth roots, which are more sensitive.
Daily habits such as teeth grinding (bruxism), using a hard-bristled toothbrush, or frequently consuming food that causes tooth sensitivity can make the condition worse.
How to Fix Sensitive Teeth at Home
If the discomfort is still mild, there are some simple steps you can try at home to both relieve and prevent sensitivity:
Use toothpaste for sensitive teeth regularly to protect your enamel.
Choose a soft-bristled toothbrush and use gentle brushing techniques.
Avoid extremely hot, cold, or acidic food and drinks.
These measures may help, but if tooth sensitivity does not improve, visiting a dentist is still important.
Professional Treatment for Sensitive Teeth
If home care is not enough, your dentist may recommend specific treatments, such as:
Application of fluoride or varnish to strengthen enamel.
Dental fillings to cover exposed areas.
Root canal treatment if the sensitivity is caused by nerve infection.
Custom night guards for patients who grind their teeth (bruxism).
With proper dental care, how to fix sensitive teeth becomes more effective and long-lasting.
Conclusion
The main causes of sensitive teeth are enamel erosion and gum recession. Daily habits and dietary choices can worsen the problem, especially when consuming food that causes tooth sensitivity. By following simple home remedies, using toothpaste for sensitive teeth, and seeking professional dental care when needed, you can enjoy eating and drinking comfortably again. Remember, prevention is always the best way to maintain long-term oral health.
