Gum recession and exposed tooth roots in older adults are common but should not be dismissed as a normal part of ageing. Receding gums may cause sensitivity, root decay and changes in appearance, and they can reveal underlying periodontal disease or damaging habits.

What is gum recession?
Gum recession means the edge of the gum has moved away from its usual position, exposing part of the tooth root. Roots have a thinner protective surface than crowns, so they may become sensitive and more vulnerable to decay.
Why are older adults more likely to have exposed roots?
Risk accumulates over time. Periodontal disease, aggressive brushing, thin gum tissue, tobacco use, poorly positioned teeth, clenching, removable appliances and past dental treatment can all contribute. Dry mouth from medicines may increase root-caries risk even when it did not cause the recession itself.
What symptoms should you notice?
- Teeth that appear longer
- A notch or colour change near the gumline
- Sharp sensitivity to cold, sweet foods or brushing
- Food trapping between teeth
- Bleeding, swelling, bad breath or loose teeth
Recession may progress without pain, which is why routine examination and periodontal measurements matter.
Can receding gums grow back?
Lost gum tissue usually does not regrow on its own. Treatment aims to stop progression, control disease and protect the exposed root. In selected cases a periodontist may recommend a gum graft or another root-coverage procedure.
How is the cause diagnosed?
A dentist measures recession and periodontal pockets, checks plaque and bleeding, reviews brushing technique and may take radiographs to assess bone. The pattern helps distinguish local trauma from generalised periodontal disease.
How can exposed roots be protected?
- Use a soft toothbrush and gentle pressure twice daily.
- Choose fluoride toothpaste and spit without vigorous rinsing.
- Clean between teeth using a method recommended for your dexterity and gum condition.
- Ask about fluoride varnish, desensitising agents or prescription fluoride when root-caries risk is high.
- Manage dry mouth and reduce frequent sugary or acidic drinks.
- Keep dentures and partial dentures clean and correctly fitted.
What treatments may help?
Options depend on the cause and severity. Professional cleaning and periodontal therapy control inflammation. Desensitising toothpaste, bonding or glass-ionomer restorations may protect worn or decayed roots. Orthodontic or bite assessment is occasionally useful. Gum grafting may improve protection and comfort when anatomy and health permit.
When is urgent care needed?
Arrange prompt assessment for increasing mobility, swelling, pus, fever, severe pain, a fracture or difficulty eating. Sudden facial swelling or trouble breathing requires emergency care.
Frequently asked questions
Is an electric toothbrush safe for receding gums?
Yes when used gently. A pressure sensor and small soft head may help, but technique matters more than force.
Can mouthwash reverse recession?
No. Mouthwash cannot replace lost gum tissue. It may support plaque control when selected for a specific need.
Does sensitivity always mean recession?
No. Tooth decay, cracks, erosion and pulp problems can also cause sensitivity, so persistent symptoms need examination.
