Why teeth get sensitive

Sensitivity happens when dentin (the layer under enamel) is exposed.
Tiny tubules in dentin let temperature and pressure reach the nerve more easily.
Common reasons include:

• Receding gums: Gum loss exposes root surfaces.
• Enamel wear: Acidic drinks, grinding, or hard brushing thin enamel.
• Tooth cracks: Hairline fractures transmit cold and pressure.
• Recent dental work: Temporary sensitivity after whitening or fillings.
• Cavities or leaking fillings: Decay and gaps irritate the nerve.

Quick relief you can try today

• Switch to a desensitizing toothpaste (use daily; don’t rinse after spitting).
• Use a soft brush with light pressure and short, gentle strokes.
• Limit acidic sips (soda, citrus, sports drinks). Rinse with water after.
• Reduce temperature extremes for a few days and avoid toothpicks.
• Wear a night guard if you clench or grind.

If pain lingers or worsens, book an exam. Some causes need in-clinic treatment.

Treatments we may recommend

• Fluoride varnish or desensitizing gels: Seal tubules and strengthen enamel.
• Bonding for root exposure: A thin resin layer shields sensitive areas.
• Gum therapy: Treats inflammation that contributes to recession.
• Bite adjustments or a custom night guard: Reduces stress on enamel and ligaments.
• Replace worn fillings or fix fractures: Restores a proper seal.
• Root canal (for deep nerve inflammation that won’t settle).

We’ll match the treatment to your exact cause so relief lasts.

Is it sensitivity or something more?

Typical sensitivity is brief and triggered by cold or sweet.
Call us sooner if you notice:

• Pain that lingers after the trigger is gone.
• Spontaneous throbbing without cold or sweets.
• Swelling, a pimple on the gum, or bad taste.
• Pain when biting or releasing pressure.

These can point to decay, a cracked tooth, or infection that needs
urgent dental care in Coquitlam.

Prevention that actually works

• Brush twice daily with fluoride toothpaste; floss once daily.
• Choose water between meals; keep acidic or sugary drinks to mealtimes.
• Use a straw for iced coffee or citrus drinks to lower acid contact.
• Schedule regular cleanings to control plaque near the gumline.
• Ask for personalized brushing technique tips during your visit.

Whitening with sensitive teeth

You can still whiten—just plan it right. We may suggest a lower-strength gel,
shorter sessions, and a two-week desensitizing toothpaste prep.
