Why You Shouldn’t Ignore Tooth Sensitivity: Causes and Solutions

Tooth sensitivity might seem like a minor nuisance—an uncomfortable twinge when you sip your morning coffee or that quick, “electric” jolt when you bite into a scoop of ice cream. However, ignoring it can lead to more serious dental issues down the road. Understanding the underlying causes of tooth sensitivity and how to treat it can help protect your smile and avoid unnecessary discomfort.

What Is Tooth Sensitivity?

Tooth sensitivity, or dentin hypersensitivity, is a sharp, temporary pain or discomfort in one or more teeth triggered by hot, cold, sweet, acidic, or cold air exposure. For some people, brushing or flossing can also cause sensitivity. While it may come and go, consistent sensitivity is often a sign of an underlying issue that requires attention.

Common Causes of Tooth Sensitivity

• Enamel Erosion: Tooth enamel is the hard outer layer that protects the dentin and pulls within your teeth. Over time, acidic foods, sugary drinks, or aggressive brushing can wear it down, exposing the sensitive dentin underneath.
• Gum Recession: When gums recede, the tooth roots become exposed. These roots lack enamel, making them more sensitive to temperature and touch.
• Tooth Decay or Cracked Teeth: Cavities, worn fillings, or cracks in your teeth can expose the dentin or pulp, causing sensitivity and pain.
• Teeth Grinding (Bruxism): Grinding or clenching your teeth can wear down enamel and cause tiny fractures in the teeth, leading to increased sensitivity.
• Overuse of Whitening Products: Some over-the-counter whitening treatments can make teeth temporarily more sensitive, especially if used too frequently.
• Recent Dental Work: Procedures such as fillings, crowns, or teeth cleanings can cause short-term sensitivity, typically subsiding within a few days.

At-Home Solutions for Sensitive Teeth

Desensitizing Toothpaste

Specially formulated toothpastes like Sensodyne® or Colgate Sensitive® help block the transmission of pain from the tooth to the nerve. Regular use can reduce sensitivity over time.

Soft-Bristled Toothbrush

Switching to a soft-bristled toothbrush and using gentle strokes can help protect enamel and reduce irritation to the gums.

Use Saltwater Rinses

Rinsing your mouth with a teaspoon of salt dissolved in a cup of lukewarm (not hot!) water twice daily can sooth the area until you can see Dr. Dani or one of her associates.

Avoid Acidic and Sugary Foods

Limiting foods and drinks that are highly acidic or sugary—like citrus fruits, soda, and candy—can prevent further enamel erosion.

Don’t Brush Immediately After Eating

This may sound counterintuitive, but studies have shown it is best to wait 30 minutes after eating before brushing your teeth. Brushing immediately after eating can damage the enamel, which is softer after eating sugary or acidic foods.

When to See Us

If your sensitivity persists for over a week or worsens over time, it’s time to consult the dentists at Kenilworth Dental Associates. Several problems cause sensitivity that may require our intervention, including:

• A cavity that needs filling
• A cracked tooth requiring a crown
• Gum disease that may need professional treatment
• An exposed root surface requiring a protective covering

Professional Treatments for Tooth Sensitivity

• Dental Bonding: A composite resin can be applied to exposed root surfaces to protect them from external triggers.
• Dental Sealants: We can apply a sealant to fill the crevices in a sensitive tooth to protect any tiny cracks in the chewing surface.
• Gum Grafting: If gum recession is the issue, a surgical graft can cover exposed roots and reduce sensitivity.
• Root Canal: In severe cases where the tooth pulp is affected, a root canal may be needed to eliminate pain and save the tooth.
