Receding gums: what causes it, and what helps

What recession actually is

Gum recession is when the gum that hugs each tooth pulls back, so more of the tooth, and eventually the root, is exposed. The crown of a tooth is covered in hard enamel, but the root isn't. It's covered by a softer, more sensitive layer, which is why exposed root surfaces feel different and behave differently.

A little recession is common as we get older, and a small amount on its own isn't a crisis. What matters is spotting why it's happening and whether it's still moving, because recession that's actively progressing is the kind worth getting on top of early. Left to run, it exposes more root, gets more sensitive, and becomes harder to manage.

Gum disease is a leading cause

The most important cause to rule out is gum disease. When plaque bacteria collect along and under the gum line, the gum becomes inflamed and, over time, the tissue and the bone that support the tooth are gradually broken down. As that support recedes, the gum goes with it.

This form of recession often comes with other signs: bleeding when you brush, puffy or red gums, bad breath, and in later stages teeth that feel loose. Because gum disease usually doesn't hurt until it's advanced, recession can be one of the visible clues that it's underway. That's why treating the gum disease is the real fix here, not just watching the gum line.

Brushing too hard, grinding and genetics

Not all recession is down to disease. A very common cause is simply brushing too hard, or using a hard-bristled brush and a scrubbing action. It feels thorough, but over years that mechanical wear pushes the gum back and can wear a notch into the tooth near the gum line. Gentler is genuinely better here.

Grinding and clenching, often at night, load the teeth in ways that can contribute to gum and tooth wear over time. And some of it is simply the hand you were dealt. Naturally thin gum tissue, the position of a tooth in the arch, and family history all play a part. Lip or tongue piercings that rub on the gum, and smoking, add to the risk too. Usually it's a combination, which is why working out your particular mix is the useful step.

Why it's worth taking seriously

The first thing most people notice is sensitivity. Exposed root surfaces react to cold, heat and sometimes sweet things, because the root doesn't have the enamel armour the crown has. That can range from a mild twinge to something that makes a cold drink genuinely unpleasant.

Beyond comfort, exposed roots are softer and more prone to decay than enamel, so recession can lead to a particular kind of cavity near the gum line that needs watching. There's the appearance too, with teeth looking longer and gaps opening up near the gums, which bothers some people quite a lot. And where recession is driven by gum disease, the same process that's moving the gum is also weakening the tooth's support, which is the part that eventually costs teeth.

What actually helps

The single most useful principle is to treat the cause, then protect what you've got. That looks different depending on why your gums are receding, which is exactly why a proper look matters. In practice, the things that help most are:

If grinding is part of the picture, a well-made nightguard takes the load off. If gum disease is driving it, a course of cleaning and gum treatment settles the inflammation so the recession stops advancing. For sensitivity, desensitising toothpastes and treatments help day to day. And where a specific tooth has lost a lot of gum, there are procedures that can cover an exposed root in the right cases, which we can talk you through and arrange if it suits your situation.

1. 1/Switch to a soft brush and a gentle, angled technique rather than hard scrubbing
2. 2/Clean between your teeth daily to keep the gum line healthy
3. 3/Have gum disease assessed and treated if it's present
4. 4/Use a nightguard if you grind or clench
5. 5/Keep up regular check-ups so any change is caught while it's small

Why prevention is the whole game

Here's the part that changes how people think about it: gum that has been lost to recession does not grow back on its own. We can stop it going further, we can manage the sensitivity, and in some cases we can cover an exposed root surgically, but we can't wish the original gum back into place. That's why catching it early is worth so much.

The encouraging flip side is that recession is very manageable once you know the cause. Ease off the brushing pressure, deal with any gum disease, protect against grinding, and keep an eye on it at your regular visits, and most people hold their gums steady for years. If you've noticed a tooth looking longer or a new patch of sensitivity, that's the moment to have it checked, while it's still small.

Quick questions

Will my gums grow back?

Not on their own. Gum lost to recession doesn't regrow. We can stop it advancing, manage the sensitivity, and in some cases cover an exposed root surgically, which is why acting early matters.

Am I brushing too hard?

If your brush bristles splay out quickly, or you use a hard brush and scrub, quite possibly. Switch to a soft brush and a gentle, angled technique. Firmer pressure doesn't clean better, it just wears the gum.

Why are my exposed roots so sensitive?

The root isn't protected by enamel the way the crown is, so it reacts more to cold, heat and sweet things. Desensitising toothpaste helps, and we can apply treatments in the chair for stubborn spots.

Can receding gums make me lose a tooth?

Recession itself doesn't, but when it's driven by gum disease the same process is weakening the tooth's support, and that can lead to loss over time. Getting the cause assessed is the important step.
