The Truth About Tooth Discoloration: Why Dark Spots Don't Always Mean Decay

I see this concern almost daily: patients pointing to dark spots on their teeth, convinced they have cavities that need immediate treatment. 

Here's the truth that might surprise you: discoloration does not equal decay.

The Science Behind Tooth Discoloration

Surface stains are the most common culprit behind tooth discoloration. These develop from:

• Coffee, tea, and red wine (among the most chromogenic beverages causing significant staining)
• Tobacco use (a major contributor to extrinsic stains)
• Certain medications like tetracycline
• Natural aging process
• Poor oral hygiene allowing plaque buildup

Actual decay, however, creates structural damage to your tooth enamel something that requires professional intervention.

The Critical Difference: What to Look For

Staining Characteristics:

• Surface-level discoloration that doesn't penetrate deep
• Smooth texture when you run your tongue over it
• No pain or sensitivity during normal activities
• Even coloration across the affected area

Decay Warning Signs:

• Rough, chalky texture you can feel
• Sharp pain when consuming hot, cold, or sweet foods
• Visible holes or pits in the tooth surface
• Progressive darkening that worsens over time

Why Professional Assessment Matters

Patients frequently mistake stains for cavities and vice versa. Meanwhile, early-stage decay can be completely invisible to the naked eye, hiding between teeth or along the gumline areas where problems often start undetected.

This is where advanced technology becomes your advantage.
