Gum recession occurs when the gum margin moves away from its previous position and exposes more of the tooth or root. It may affect one tooth or several. Some people first notice sensitivity, a longer-looking tooth, or a notch near the gumline; others learn about it during an examination.
Lost gum tissue generally does not grow back on its own. However, identifying the cause may help reduce further damage, manage sensitivity, and determine whether a procedure to protect or cover an exposed root should be considered. The right plan depends on why the recession is occurring.
What can cause or contribute to gum recession?
Recession can be associated with periodontal disease, traumatic brushing, thin gum tissue, tooth position, tobacco use, clenching or grinding, or repeated irritation. More than one factor may be present. A photograph or mirror check cannot show the condition of the supporting bone, periodontal pockets, bite, or all other causes of sensitivity.
What does the dental assessment look for?
The dentist or periodontal clinician may review when the change began, measure the gums, check for plaque and inflammation, examine tooth position and the bite, and assess sensitivity or wear near the gumline. Imaging may be recommended when it is needed to evaluate supporting structures or another dental problem.
The goal is to distinguish active disease or ongoing trauma from a stable area of recession and to identify risks that can be modified. That distinction guides whether monitoring, nonsurgical care, restorative treatment, periodontal treatment, or referral should be discussed.
Can changing my brushing technique help?
Gentle cleaning with a soft-bristled toothbrush may reduce avoidable trauma, but it does not replace an examination and does not restore lost tissue. Ask the dental team to demonstrate a technique and recommend a toothpaste or sensitivity product that fits your needs. Continue cleaning between the teeth as instructed; avoiding an area completely can allow plaque to accumulate.
Do-it-yourself acids, abrasives, and unproven remedies can irritate tissues or damage exposed root surfaces. If a product burns, causes pain, or seems to worsen the area, stop using it and ask a dental professional for advice.
Which treatments might be discussed?
Treatment is selected for the cause and the patient’s priorities. The conversation may include professional cleaning or periodontal therapy when disease is present; changes in home-care technique; desensitizing products; protective or restorative treatment for an exposed or damaged root; evaluation of tooth position or bite forces; and periodontal procedures such as gum grafting for selected sites.
No single option is right for every recessed area. Ask what the proposed treatment is intended to accomplish, what it will not change, how the area will be maintained, and what alternatives are reasonable if you choose to monitor it.
When should I schedule an assessment?
Request an examination if you notice a newly exposed root, increasing sensitivity, a visible notch near the gumline, persistent bleeding or swelling, a tooth that feels loose, or a change that appears to be progressing. Prompt review is also useful when recession affects cleaning or when you are considering whitening or other cosmetic treatment.
Severe pain, pus, fever, rapidly increasing swelling, facial swelling, or difficulty breathing or swallowing needs urgent evaluation; breathing or swallowing difficulty is an emergency.
