First-line treatments
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Resin Infiltration Technique
Minimally invasive treatment using low-viscosity resin infiltrated into porous enamel to improve aesthetics and strengthen tooth structure. Particularly effective for hypomaturation AI with subsurface lesions.
Enamel Hardness Monitoring
Periodic assessment of enamel surface hardness and integrity to track disease progression and guide timing of restorative interventions. May include microhardness testing.
Additional treatment options
Zirconia Crowns
Metal-free zirconia crowns providing excellent durability and aesthetics for anterior and posterior teeth affected by hypomaturation AI. Offers biocompatibility and resistance to wear.
surgicalEnamel Protection During Activities
Use of custom protective mouthguards during sports and avoidance of abrasive dental products. Includes guidance on managing tooth sensitivity common in hypomaturation types.
lifestyleRemineralization Support
Adjunctive use of calcium phosphate products such as casein phosphopeptide-amorphous calcium phosphate to support natural remineralization of affected enamel. Complements restorative treatments.
