Sensitive Teeth: Why It Happens and What You Can Do About It

Have you ever taken a sip of your favorite ice-cold drink or indulged in a hot cup of coffee, only to feel a sharp pain in your teeth? That uncomfortable sensation is known as tooth sensitivity. Sensitive teeth can cause discomfort and pain.

• Tooth sensitivity happens when the protective enamel on your teeth wears down, exposing the sensitive dentin beneath.

But what causes this to happen, and how can you prevent it? In this article, our cosmetic dentist at Smile Avenue Dentistry provides you with practical solutions to manage tooth sensitivity.

Common Causes of Tooth Sensitivity

The dentin contains tiny channels that connect to the tooth’s nerves. When exposed to hot, cold, sweet, or acidic stimuli, these channels allow sensations to reach the nerves, causing that sharp pain or discomfort. 

• Acidic foods and drinks can gradually wear down the protective enamel on your teeth.
• As gums pull back, they expose the tooth root, which lacks the protective enamel.
• Constant grinding or clenching can wear down the enamel and cause sensitivity.
• Cavities and old or worn-out fillings can expose sensitive parts of your teeth.
• Some teeth whitening products can temporarily increase tooth sensitivity.
• Temporary sensitivity is common after treatments like deep cleanings or teeth straightening.

This study found that about one in eight people visiting dental clinics reported experiencing dentin hypersensitivity. It was more common among younger individuals, women, and those with a history of gum recession or frequent at-home teeth whitening treatments.

Chronic sensitivity can be frustrating and interfere with your day-to-day routine. You may avoid certain foods or drinks and brushing can become uncomfortable. Persistent discomfort can make you hesitant to eat or drink in social settings.

How to Find Relief from Tooth Sensitivity

Finding relief from tooth sensitivity often requires a combination of treatments and lifestyle changes. According to this article, the best approach starts with simple, non-invasive solutions like switching toothpaste or identifying and addressing the cause of the sensitivity. Only if these don’t work should more advanced treatments be considered.

1. Desensitizing Toothpaste and Products

Desensitizing toothpaste is one of the simplest and most effective ways to reduce tooth sensitivity. Here’s what to look for:

• Potassium nitrate helps block nerve signals in the tooth.
• Fluoride strengthens enamel and reduces sensitivity.

You need to use the toothpaste regularly, as it may take a few weeks to notice results. Additionally, your dentist may recommend fluoride gels or varnishes to strengthen your enamel.
