Gum recession and sensitive teeth: how exposed roots happen
dentalhealth
Gum recession is one of the most common reasons roots become sensitive. Here's how it develops, what to watch for, and how it's managed.
Gum recession often happens slowly, so many people don't notice it until a tooth starts reacting to cold. Understanding how it works can help you protect your smile.
What gum recession is
Gum recession is when the gum tissue around a tooth pulls back and exposes more of the tooth, including the root. Roots don't have enamel covering them, so they tend to be more sensitive to cold, sweets and touch.
Common contributors
- Brushing too firmly or with a hard brush
- Gum disease
- Teeth grinding or clenching
- Natural thinning of gum tissue
- Teeth that are crooked or sit toward the edge of the bone
Signs to watch for
- A tooth that looks longer than it used to
- A notch near the gumline you can feel with your tongue
- Sensitivity at the gumline
- Gums that bleed or look red
How it can be managed
The right approach depends on the cause. Gentler brushing and a desensitizing toothpaste are a good start. Treating gum inflammation, adjusting a bite, or covering exposed areas with bonding may help too. Your dentist can explain which options suit you.
Why a check-up matters
