receding gums: causes and what can be done

By Dr. Aakash Rana, DDS · Updated September 2026 · 6 min read

Short answer: Gum recession has several common causes — from gum disease to brushing too hard to genetics — and while gum tissue doesn't regenerate on its own, the underlying cause can often be managed and further recession slowed or stopped.

Noticing that your teeth look a little longer than they used to, or that your gumline has visibly shifted over time, is a common concern that tends to develop slowly enough that most people don't catch it right away when it starts. Here's what's usually behind it and what your realistic, honest options actually are once it's been identified.

Gum Disease Is a Leading Cause

Ongoing inflammation from gum disease is one of the most common reasons gums recede over time — as the tissue and supporting bone are gradually affected, gums can pull away from the tooth, exposing more of the root surface underneath. This is one more solid reason gum disease is worth catching and addressing early through regular cleanings, well before recession becomes a separate, highly visible issue layered on top of it. Recession caused this way often shows up unevenly across the mouth, tracking closely with wherever plaque and inflammation have been most persistent over time.

Brushing Too Hard, More Often Than You'd Think

It seems counterintuitive at first, but brushing too aggressively or using a hard-bristled toothbrush can actually wear away gum tissue over time, especially along the outer surfaces of teeth facing the cheek. Many people do this without ever realizing it, mistakenly assuming that more pressure automatically means a cleaner mouth. Switching to a soft-bristled brush and adopting a gentler technique — letting the bristles do the actual work rather than pressing hard against the gumline — is a simple, genuinely meaningful change most people can make immediately. If you tend to go through toothbrush bristles quickly or notice them fraying within just a few weeks, that's usually a reliable sign you're brushing harder than necessary.

Genetics and Tooth Position

Some people are simply more prone to naturally thin gum tissue, or have teeth positioned in a way (such as a tooth sitting slightly outside the normal dental arch) that makes the gum tissue covering it naturally thinner and more vulnerable to recession over time. This isn't something caused by anything you did wrong personally, and it's genuinely worth knowing about if recession runs in your family, so you can be proactive early with gentle care and regular monitoring. Mentioning a family history of thin gum tissue or early recession at your first visit helps your dentist watch those specific areas more closely at each future checkup.

Other Contributing Factors

Teeth grinding, a poor bite alignment that puts uneven pressure on certain specific teeth, tobacco use, and oral piercings that repeatedly rub against gum tissue can all contribute meaningfully to recession as well over time. Identifying which of these factors actually applies to you is part of what happens during a proper dental exam — recession usually has more than one contributing factor working together rather than a single, obvious standalone cause. Because these causes are so varied, two people can have very similar-looking recession for completely different underlying reasons, which is exactly why a one-size-fits-all home remedy rarely addresses the actual problem. A dentist looking at your specific pattern of recession can usually narrow down the most likely contributing cause fairly quickly, which then points directly to the most useful next step for your particular situation, whether that's a general dentistry visit for a bite adjustment or a referral for grafting.

What Can Actually Be Done About It

Gum tissue that has already receded doesn't grow back on its own naturally, but treatment isn't just about passively accepting it as permanent — addressing the underlying cause directly (better brushing technique, treating existing gum disease, adjusting a bite issue, or a nightguard for grinding at night) can genuinely stop it from getting any worse over time. In more advanced cases, gum grafting procedures can actually rebuild some lost tissue. The right approach depends entirely on the specific cause, which is best identified at a free consult exam rather than guessed at home on your own.

Why Exposed Roots Are Worth Addressing, Not Just Ignoring

Beyond appearance, exposed tooth roots from recession lack the protective enamel layer that covers the rest of the tooth, which means they're more prone to sensitivity, especially to cold, and more vulnerable to decay since root surfaces are softer than enamel. This is why recession isn't purely a cosmetic concern, even in mild cases — the exposed area genuinely needs a bit more attention during brushing and at cleanings than the rest of the tooth. A dentist can point out exactly which areas need extra care and recommend a toothpaste or approach suited to sensitive, exposed root surfaces at your next cleaning.
