Gum recession is a condition in which the gum tissue pulls back and gradually exposes the root of the tooth. Beyond the aesthetic impact, it can cause strong sensitivity to cold and heat, and increase the risk of root caries and even tooth loss if it is not treated in time.
What causes gum recession?
There are several main factors that can cause recession:
- Aggressive brushing – using a toothbrush that is too hard or applying too much pressure gradually wears away the delicate gum tissue over time.
- Gum disease (periodontitis) – the buildup of bacterial plaque and tartar causes chronic inflammation that damages the bone and the gum tissue supporting the tooth.
- Genetic predisposition – some people are born with thinner, more sensitive gum tissue.
- Teeth grinding (bruxism) – ongoing pressure on the teeth transfers load to the gums and the supporting bone.
- Smoking and other factors – smoking, hormonal changes, and uncontrolled orthodontic treatment can also contribute to the process.
Signs to watch for
Gum recession develops gradually, and often without pain at first. Common signs include:
- increased sensitivity to cold or hot food or drinks
- teeth that look “longer” than before
- a step-like or notched feeling where the tooth meets the gum
- gums that are red, swollen, or bleed easily
How is it treated?
The approach depends on the severity of the recession and its cause:
- Mild cases – instruction on correct brushing technique, switching to a soft toothbrush, and professional tartar cleaning can stop the process.
- Moderate cases – root planing (deep cleaning below the gum line) is sometimes required to remove bacteria and deep tartar.
- Advanced cases – gentle surgical treatments (such as a gum graft) may be considered to re-cover the exposed root and improve both appearance and protection.
It is important to understand: gum recession does not reverse on its own. The earlier it is identified and treated, the easier it is to stop the damage and keep the teeth healthy long term.
When should you get checked?
If you notice new sensitivity, a change in the appearance of your gums, or if someone in your family has gum disease — it is worth coming in for an examination. Early diagnosis allows simpler treatment and helps prevent complications later.
