Why are my gums receding?
Gum recession happens when gum tissue pulls back from tooth roots, often due to brushing habits, gum disease, grinding, genetics, or tobacco use. Early evaluation by a dentist helps prevent sensitivity and decay.

What Causes Gum Recession?
Gum recession happens when the tissue that covers and protects your tooth roots pulls back or wears away. Several habits and conditions can trigger this.
Brushing Habits
Aggressive brushing—especially with a hard-bristled toothbrush—is one of the most common causes. Even if your intention is to clean thoroughly, vigorous scrubbing can damage delicate gum tissue over time. The solution is gentler: use a soft-bristled brush and light pressure when brushing.
Gum Disease
When bacteria build up on your teeth, they can infect the gum tissue and bone that anchor your teeth. As gum disease progresses, gums pull away from teeth. This is one reason why treating gum disease early matters—it can slow or prevent further recession.
Teeth Grinding
If you grind your teeth at night (a condition called bruxism), the constant force can stress your gums and cause them to recede. A night guard, fitted by your dentist, protects your teeth and gums while you sleep.
Genetics
Some people are simply more prone to gum recession because of their genetic makeup. If family members have had receding gums, you may be at higher risk. This doesn’t mean recession is inevitable, but it’s worth being extra diligent with oral care.
Tobacco Use
Smoke and smokeless tobacco irritate gum tissue and weaken your immune system’s ability to fight infection. Both increase recession risk.
Why Gum Recession Matters
When gums recede, the yellow or cream-colored root of your tooth becomes visible. Unlike the hard, white enamel that covers the crown of your tooth, roots are softer and unprotected. This exposes you to:
- Tooth sensitivity – especially to cold, heat, or sweet foods
- Decay – the softer root material decays more easily than enamel
- Further gum damage – recession tends to worsen if the underlying cause isn’t addressed
Receded gum tissue does not grow back on its own. This is why early intervention is important.
What You Can Do
Adjust your brushing technique. Switch to a soft-bristled brush and use gentle, small circular motions rather than hard scrubbing. Let the brush do the work; your arm shouldn’t need to press hard.
Address gum disease. If your dentist diagnoses gum disease, treatment is key to stopping recession. This may involve professional cleaning, improved home care, or other steps your dentist recommends.
Manage grinding. If you suspect you grind your teeth, mention it at your next visit. A night guard is a simple, effective prevention tool.
Quit tobacco. Stopping tobacco use reduces irritation and gives your immune system a chance to heal gum tissue.
See your dentist regularly. Routine visits catch early signs of recession and gum disease before they worsen. Your dentist can also review your brushing technique and suggest adjustments.
Treatment and Next Steps
If recession is mild, managing the underlying cause (better brushing, treating gum disease, using a night guard) may prevent it from progressing. If recession is more advanced or causing significant sensitivity or decay risk, your dentist may recommend professional treatment options.

Whether you need a gentle cleaning, a night guard, treatment for gum disease, or a referral for advanced care, your dentist will help you understand your options and move forward confidently.
Frequently asked questions
Can receding gums grow back on their own?
No. Gum tissue does not regenerate once it has pulled away from the tooth. A dentist can assess whether professional treatment or monitoring is right for you.
What's the main risk of gum recession?
When gums recede, the root of your tooth becomes exposed. Tooth roots are softer than the crown and more prone to sensitivity and decay.
Can I prevent gum recession from getting worse?
Yes. Gentle brushing with a soft-bristled brush, treating gum disease, managing grinding habits, and regular dental visits can help slow or prevent further recession.
