Minimally Invasive Dentistry

Source revision:: adopted 2023

Board takeaway

Minimally invasive dentistry means active disease control with the least necessary loss of tooth structure.

Combine family-supported prevention, lesion-specific treatment, and surveillance; restore when needed.
A stabilization plan is incomplete without reassessment of caries activity, pain, infection, and the feasibility of definitive care.

Prevention and disease control

Establish a dental home by 12 months: assess risk, educate caregivers, and prevent disease before lesions develop.
Treat incipient lesions to slow, stop, or reverse progression. For cavitation, individualize surgical or nonsurgical care.
Target the plaque biofilm–carbohydrate interaction through sustained family engagement, less frequent carbohydrate exposure, oral hygiene with fluoridated toothpaste, and professional fluoride.
Lesion-level options include remineralization, arrest, sealing, selective removal of carious tissue, and restoration.

Intervention	Decision and limit
Fluoride varnish	Encourage remineralization
Silver diamine fluoride (SDF)	Promote arrest of eligible caries lesions
Sealants	Prevent pit-and-fissure caries/arrest noncavitated lesions; monitor retention and reapply when needed
Resin infiltration	Noncavitated proximal enamel/outer-third dentin lesions; restoration remains an option
Interim therapeutic restorations (ITR)	Bridge to definitive restoration or primary-tooth exfoliation
Hall-technique stainless steel crowns	Minimal intervention option; assess eligibility using technique-specific guidance

Preserve tooth structure and vitality

Bonded restorations reduce the need for extensive traditional preparations.
For deep caries in vital teeth, complete removal of all carious dentin is no longer the default described here. Incomplete removal aims to avoid pulp exposure and preserve vitality, improving long-term prognosis.
Replacing restorations removes additional tooth structure. Repeated failure/replacement can ultimately lead to full coverage or extraction.

Stabilization and follow-up

Varnish, SDF, ITR, and Hall crowns may be particularly useful for pre-cooperative or anxious children, patients with special health care needs, and those with limited access to care.
They may stabilize disease while awaiting rehabilitation under general anesthesia or defer non-emergent care because of age or health status.
Reassess caries risk and lesion activity; monitor pain and signs/symptoms of infection. Provide more frequent professional recare, including fluoride, and individualized diet/hygiene counseling.
Most MID interventions produce no aerosols, which can be useful when aerosol generation must be minimized.

Evidence and limits

This policy supports a philosophy of care and several intervention options.

Use the linked SDF, restorative dentistry, and pulp therapy guidance to match an intervention to lesion depth, symptoms, pulp status, and restorability.

Common board traps

Answer aloud

A young child is awaiting definitive rehabilitation. What can you do meanwhile?

Use eligible minimally invasive measures to stabilize disease, with prevention and active surveillance while definitive care is arranged.

Select by tooth and patient: symptoms, pulp status, lesion characteristics, and cooperation determine whether varnish, SDF, ITR, or a Hall crown is suitable.
Disease control: Address frequent carbohydrate exposure and supported brushing, and arrange more frequent reassessment of activity, pain, and infection.
Limit: These options can bridge a delay in definitive care; each still requires appropriate case selection.

Why avoid complete excavation of deep caries in a vital tooth?

Selective caries removal can reduce pulp exposure and preserve vitality and sound tooth structure.

Continuing care: A restoration alone does not control the underlying disease, so pair tooth preservation with risk reduction and follow-up.
Eligibility: This reasoning applies to eligible vital teeth; assess the pulpal diagnosis rather than extending it to a tooth with signs of necrosis or infection.
