Gum recession: why it happens and what to do
In short: gum recession —when “the teeth look longer” and the root becomes visible— is usually caused by brushing too hard, gum disease, bruxism or tartar. Lost gum does not grow back on its own, so the urgent thing is to stop the cause; in some cases it can be covered with a graft. It causes sensitivity and a greater risk of decay on the root, which is why it’s worth getting it checked.
Why are my gums receding?
It’s almost never down to a single thing. The most common causes:
- Aggressive brushing. Pressing too hard or using a hard brush “files away” the gum. It’s the most typical cause and the most avoidable.
- Gum disease. Periodontitis destroys the support and the gum pulls back.
- Bruxism. Clenching and grinding overloads the tooth and encourages recession.
- Built-up tartar and, sometimes, genetics or the position of the teeth.
Identifying which is your cause is the first thing, because the solution depends on it.
Why does it need treating?
Because the root that is left exposed has no enamel to protect it, so the following appear:
- Sensitivity to cold, heat or when brushing.
- A greater risk of decay on the root.
- A warning that something is wrong (brushing or gums).
It’s not a dramatic emergency, but ignoring it lets it get worse.
Is there a solution?
Yes, in two steps:
- Stop the cause. Switch to gentle brushing (a soft brush, without “scrubbing”), treat the periodontitis if there is any, control the bruxism with a splint. This prevents it from continuing to recede.
- Recover, where appropriate. The gum doesn’t grow on its own, but in some cases a gum graft can be carried out to cover the root, as part of periodontics. The specialist assesses this based on your case.
The most important clue
If you notice your teeth looking “longer”, sensitive, or you see that the gum is pulling back, check how you brush: most of the time the problem starts there. And book a check-up to rule out gum disease.
We assess the recession and its cause in consultation, without scaremongering. The first visit is free. Book an appointment whenever you like.
Frequently asked questions
Why do gums recede?
The most common causes are brushing too hard or with a hard brush, gum disease (periodontitis), bruxism and the build-up of tartar. Genetics and the position of the teeth also play a part. Receded gum does not grow back on its own.
Is there a solution for gum recession?
The first thing is to stop the cause so that it doesn't get worse. Lost gum does not recover on its own, but in some cases it can be covered with a gum graft. The periodontist assesses this based on how much it has receded and why.
Is it serious if the root of the tooth is visible?
It's worth treating. The exposed root causes sensitivity, is more prone to decay and usually indicates that something is wrong (aggressive brushing or gum disease). It's not an emergency, but it is reason for a check-up.
