Receding gums means the gum tissue around your teeth is pulling back or wearing away, exposing more of the tooth root than normal. This is a common condition, and it usually happens gradually enough that you don’t notice it right away. By the time you do, you may already have noticeable sensitivity or a visible change in how your teeth look. The good news is that recession can be managed and, in many cases, reversed with treatment.
How to Tell If Your Gums Are Receding
The most obvious sign is that your teeth look longer than they used to. What you’re actually seeing is the root surface, which is normally hidden beneath the gum line. Roots don’t have the same protective enamel coating as the visible part of your tooth, so once they’re exposed, you’ll likely notice increased sensitivity to hot, cold, and sweet foods or drinks.
Other signs include pain or discomfort right along the gum line, sensitivity when brushing or flossing, and discomfort during dental cleanings. You might also feel a notch or ridge near the base of a tooth where the gum has pulled away. Some people first notice recession because one tooth suddenly feels different from its neighbors.
What Causes Gums to Recede
There are two broad categories: gum disease and mechanical damage. Often, both are happening at the same time.
Periodontal (gum) disease is the most common cause. Bacteria build up along and below the gum line, triggering inflammation that gradually destroys the bone supporting your teeth. As that bone is lost, the gum tissue follows it downward, exposing the root. This type of recession tends to affect multiple teeth and can progress silently for years before you notice symptoms.
Mechanical damage, primarily from brushing too hard, is the other major driver. Research shows the average person brushes with about 2.3 newtons of force, but recession becomes significantly more likely above 3 newtons. Severe recession has been linked to brushing forces around 3.8 newtons. The back-and-forth “scrubbing” technique most people default to is particularly damaging to the gum line, creating localized abrasion in the cervical area where the gum meets the tooth. Hard-bristled brushes make this worse by concentrating more pressure on a smaller area.
Other contributing factors include teeth grinding or clenching (which overloads the periodontal ligament and accelerates bone loss), misaligned teeth that put uneven pressure on certain areas of gum tissue, tobacco use, hormonal changes during pregnancy or menopause, and genetic predisposition. Some people simply have thinner gum tissue that’s more vulnerable to recession regardless of their habits.
What Happens If You Ignore It
Recession doesn’t reverse on its own, and the consequences of leaving it untreated go beyond sensitivity. The exposed root surface is softer than enamel and far more susceptible to decay. Without gum tissue acting as a seal, bacteria can access deeper structures around the tooth.
The more concerning issue is bone loss. In recession cases, the bone that supports the affected tooth is often already thinning. When this bone loss is limited to one side of a tooth, it creates a defect called a dehiscence, where the bone essentially drops below where it should be, and the gum follows. Over time, this can lead to increasing tooth mobility. Excessive bite forces on an already compromised tooth can accelerate this process by triggering chemical signals that promote further bone breakdown. Left long enough, the result is tooth loss.
Non-Surgical Treatment
For mild recession, especially when gum disease is involved, the first step is usually a deep cleaning called scaling and root planing. Your dentist or hygienist uses specialized tools to remove bacterial buildup from below the gum line and smooth the root surfaces so gum tissue can reattach more easily. Clinical trials show this procedure significantly reduces recession when periodontal pockets are 4 millimeters or deeper. For shallower pockets, the benefit is less dramatic, but it still helps control the underlying infection.
After the initial deep cleaning, follow-up maintenance matters. Studies comparing monthly versus quarterly professional cleanings after deep cleaning found that both schedules produced significant improvements in gum recession, pocket depth, and inflammation at six months. Your dentist will recommend a schedule based on how advanced your condition is.
Surgical Options for Advanced Recession
When recession has progressed to the point where root coverage is needed, gum grafting is the standard approach. Several techniques exist, but the sub-epithelial connective tissue graft consistently performs best in clinical studies. This involves taking a small piece of tissue from beneath the surface of your palate and securing it over the exposed root. A review of multiple studies found this technique achieves an average of 89.3% root coverage, meaning most of the exposed root gets covered back up.
There are variations on this approach. A pedicle graft rotates nearby gum tissue over the recession site rather than transplanting tissue from the palate. Donor tissue from a tissue bank can also be used, which eliminates the need for a second surgical site in your mouth. Your periodontist will recommend one based on how much recession you have and how much healthy tissue surrounds the affected area.
The Pinhole Technique
A newer, minimally invasive option works well for mild to moderate recession. Instead of cutting and grafting tissue, a tiny pinhole is made in the gum, and specialized instruments loosen the existing tissue so it can be slid into a better position over the exposed roots. Collagen strips are placed underneath to stabilize everything while it heals. There are no stitches, and most patients return to normal activities within a day or two. Recovery is dramatically faster: many people feel nearly back to normal within three to five days, compared to weeks with traditional grafting.
How to Prevent Further Recession
If you already have some recession, preventing it from getting worse is just as important as treating what’s already happened. The biggest change most people need to make is how they brush.
Switch to a soft-bristled toothbrush. Soft bristles (0.15 to 0.2 mm in diameter) are more flexible, which means they contact more surface area and clean effectively without concentrating force on your gum line. Hard bristles produce significantly more tooth surface loss and gum damage at the same brushing force. Never use a medium or hard brush.
Replace the scrubbing motion with gentle, circular strokes. The horizontal back-and-forth technique that most people use is the single most damaging brushing pattern for your gums. Think of brushing as polishing rather than scrubbing. If you use an electric toothbrush, let the brush head do the work. Move it slowly from tooth to tooth, pausing at the gum line, and don’t press it into your teeth the way you would a manual brush. Many electric models now have pressure sensors that alert you when you’re pushing too hard.
Beyond brushing, managing gum disease through regular flossing and professional cleanings is essential. If you grind your teeth at night, a night guard can reduce the excessive force that accelerates bone loss around vulnerable teeth. Quitting tobacco, if applicable, removes one of the most significant risk factors for both gum disease and poor healing after treatment.
