Removing white spots on the front teeth of patients using the resin infiltration method

The white spots on the front teeth can be an aesthetic concern for many patients. These lesions, known as incipient hypomineralization or enamel hypoplasia, can vary from a mild white-yellowish appearance to a more severe brown-orange discoloration. They are easily distinguishable from other enamel defects as the affected areas are often asymmetrical with irregular borders.

These spots can be caused by various factors such as fluorosis, dental trauma, or various systemic conditions. Treating these white spots can be challenging, but resin infiltration offers an effective and aesthetic solution for patients.

What is resin infiltration?

Resin infiltration is a minimally invasive technique aimed at treating incipient lesions on the enamel, including white spots. It involves applying an infiltrative resin solution to the surface of the lesion. This solution penetrates the enamel and fills its pores with resin, restoring the natural appearance of the enamel and making the white spots less visible or even disappear.

Who is this treatment for?


Children with incipient hypomineralization lesions on the incisors and permanent molars (MIH syndrome): Resin infiltration is a promising therapeutic option for treating MIH lesions. Many children develop white spots on their teeth for various reasons, and resin infiltration may be a suitable solution to treat these lesions.

Children with dental fluorosis: Fluorosis is a condition where dental enamel develops abnormally due to excessive fluoride exposure. This method can be useful in improving the aesthetic appearance of affected teeth.

Children seeking minimally invasive treatments: For parents wishing to avoid invasive and painful procedures for their children, resin infiltration may be a good option. The method does not require anesthesia and is relatively comfortable.


Adults with incipient white spots on their teeth: Adults with white spots on their teeth, whether due to dental trauma, fluorosis, or other causes, can benefit from this method to improve the aesthetic appearance of their smile.

Adults seeking non-invasive aesthetic treatments: For those wishing to improve the aesthetics of their teeth without resorting to invasive or painful procedures, resin infiltration may be an attractive solution.

Adults with dental sensitivity: This method is also suitable for adults suffering from dental sensitivity, as it is a minimally invasive procedure that does not exacerbate sensitivity.

Treatment steps:

  • Initial evaluation: Before starting treatment, it is crucial for the dentist to conduct a comprehensive evaluation of dental lesions and their causes. This assessment will determine if resin infiltration is suitable for the patient and the type of lesion present.

  • Preparation of the dental surface: The surface of the affected teeth must be prepared beforehand for the application of the resin solution. This process may involve additional cleaning of the dental surface and the application of a special acid to prepare the enamel for infiltration.

  • Application of the resin solution: After preparing the dental surface, the infiltrative resin solution is applied directly to the white spots. This solution consists of a special resin blend that penetrates the enamel and fills its pores, providing an aesthetic solution for the lesions.

  • Final polishing: After applying the resin solution and allowing it to penetrate the enamel, the dental surface is polished to achieve a natural and uniform appearance. This step helps to seamlessly integrate the resin into the dental enamel.

Patients seeking an aesthetic solution for white spots without resorting to invasive treatments such as fillings or dental crowns.


  • Minimally invasive: Resin infiltration is a minimally invasive treatment that does not involve the removal of healthy dental tissue.

  • Aesthetic: This method offers remarkable aesthetic results, restoring the natural appearance of dental enamel without affecting its structure.

  • Comfortable for the patient: The procedure is relatively quick and comfortable for patients, without the need for anesthesia or other painful interventions.

  • Reversible: In case the patient later decides to opt for other treatments such as fillings or dental crowns, resin infiltration can be reversible.

In conclusion, resin infiltration is an effective and aesthetic solution for removing white spots on the front teeth of patients. With a simple, minimally invasive process and remarkable aesthetic results, this technique offers patients an excellent alternative to traditional treatments.
