Tooth sensitivity is one of the most common dental concerns. Characterized by a sudden, sharp discomfort in response to hot, cold, sweet, or acidic foods, it can interfere with daily routines and reduce overall quality of life.
Understanding what causes tooth sensitivity is the first step toward treating it effectively. Here are some of the most common triggers:
Acidic Foods & Drinks
Foods and beverages high in acid, like citrus fruits, tomatoes, coffee, and tea, can wear down your tooth enamel over time. Once enamel erodes, it exposes the softer layer underneath (called dentin), making your teeth more sensitive to temperature changes and certain foods.
Brushing Too Hard
Brushing with too much pressure or using a hard-bristled toothbrush may feel thorough, but it can actually damage your enamel and irritate your gums. Over time, aggressive brushing can lead to gum recession and enamel loss, both of which increase tooth sensitivity.
Gum Disease
Gum disease, including gingivitis and more advanced periodontitis, can cause gum recession. This recession exposes the roots of your teeth, which are not protected by enamel, making them more vulnerable to hot, cold, or sweet sensations.
Teeth Grinding (Bruxism)
Regularly clenching or grinding your teeth, especially at night, can wear down enamel and even cause small cracks, both of which increase tooth sensitivity. If you wake up with jaw pain or frequent headaches, grinding may be the culprit.
Teeth Whitening Products
While whitening treatments can enhance your smile, some over-the-counter and professional products may temporarily increase sensitivity. This often results from peroxide-based ingredients penetrating the enamel and irritating the dentin layer underneath.
How to Treat Tooth Sensitivity
Tooth sensitivity can often be managed at home or treated with professional help, depending on the cause and severity. Here are some effective treatment options:
Desensitizing toothpaste
Over-the-counter desensitizing toothpastes contain ingredients like potassium nitrate or stannous fluoride, which help block pain signals from reaching the nerves inside your teeth. With consistent use, many people see noticeable relief. Want to know which toothpaste is best for sensitive teeth?

Use a Soft Bristled Brush
Switching to a soft-bristled brush and using gentle, circular motions can reduce irritation. Pair it with a non-abrasive toothpaste to protect your enamel and gums for the best result.
Fluoride Treatments
Your dentist may be able to apply fluoride to the sensitive areas of your teeth. This can help strengthen your enamel and reduce tooth pain. Your dentist might also suggest using fluoride at home.
Sealants
If your tooth roots are exposed, your dentist may recommend applying a sealant. Sealants are a thin, protective coating that shields the area from irritants. In more severe cases, a gum graft may be suggested to cover exposed roots and restore protection. To learn more, read “What are Sealants?” from the Clevland Clinic.
When to See a Dentist for Tooth Sensitivity
If you’re experiencing ongoing or worsening tooth sensitivity; it’s time to talk to your dental provider. They can check for underlying issues, rule out cavities or gum disease, and recommend the best treatment based on your symptoms. As always, attending your 6-month cleaning also helps to stop problems before they begin. Schedule your visit with Smile Dental today.
