A prevention-first approach
The WHO document emphasizes keeping healthy tooth tissue intact wherever possible and choosing interventions according to the patient's risk and clinical findings. It assesses effectiveness, safety, cost-effectiveness and environmental impact rather than promoting one universal filling method.
A small early lesion, an established cavity and a heavily damaged tooth are different situations. The right decision starts with diagnosing the stage and activity of disease.
What treatments are considered?
The guidance reviews fluoride varnish, silver diamine fluoride, pit-and-fissure sealants, glass ionomer cements, resin-based composites and related techniques. These measures serve different purposes: prevention, management of some lesions or restoration of lost tooth structure.
It also addresses safe use of mercury-free materials, shared decision-making and precautions for vulnerable groups. This does not mean every patient should receive every intervention or that fillings are no longer necessary.
Why early visits matter
When decay is found early, a dentist may have more options to preserve sound tissue. Brushing habits, diet, fluoride exposure and personalized preventive visits all influence future risk. Once a cavity has formed, a restoration may be necessary to protect function and avoid progression.
A photo or online symptom checklist cannot reliably determine whether a spot needs monitoring or treatment.
What to ask at your appointment
Ask whether a lesion is active, what conservative options are possible, why a particular material is recommended and how recurrence can be prevented. A transparent discussion of benefits and limitations is central to the WHO's approach.
