A healthy smile begins before cavities appear. Fluoride therapy and dental sealants are two of the most effective methods for protecting teeth in a simple, painless, and long-lasting way—especially in children and adolescents, but also in adults with a higher risk of cavities.
At OnlySmile in Ponta Delgada (São Miguel, Azores), we believe that prevention is always better than treatment. We use safe technologies and current clinical protocols to strengthen the tooth enamel and create a protective barrier that prevents bacterial advancement.
The Essentials
- Fluorotherapy strengthens enamel and prevents the onset of cavities.
- Dental sealants act as a physical barrier on chewing surfaces.
- These are quick, painless treatments ideal for children, teenagers, and adults.
- Regular application of fluoride and sealants reduces the need for future restorations.
- Prevention saves time, discomfort, and costs over a lifetime.

- Frequently Asked Questions (FAQ)
1. What is fluorotherapy
Fluorotherapy is the controlled application of fluoride to strengthen tooth enamel. Fluoride works by making the tooth more resistant to demineralization caused by bacteria and acids present in food.
Treatment can be performed using gels, varnishes, or foams applied by the dentist. It is fast, painless, and ideal for those prone to cavities or tooth sensitivity.
At OnlySmile, this application is personalized according to the age and individual risk of each patient.
2. What are dental sealants
Dental sealants are thin layers of resin that cover the fissures and grooves of the teeth — especially on molars, where brushes do not easily reach.
They function as a protective barrier that prevents the accumulation of bacteria and food debris, drastically reducing the risk of cavities.
They are transparent, aesthetic, and completely painless. The application is quick and safe, especially recommended during childhood and adolescence.
3. How they work in cavity prevention
While fluoride acts chemically by strengthening the enamel, sealants work mechanically, preventing bacteria from contacting the tooth surface.
The combination of the two treatments is, therefore, a form of dual protection — one shields the surface, the other reinforces the structure.
This integrated approach is an essential part of OnlySmile’s preventive philosophy, complementing other care such as professional oral hygiene and dental check-ups.
4. Professional fluoride vs. fluoride in toothpaste
The fluoride present in toothpastes and mouthwashes is important but has a low concentration for daily use.
In professional fluorotherapy, fluoride is applied in safe but more effective concentrations directly to the teeth.
The result is a deep remineralization that protects for months.
Additionally, the treatment is controlled by the dentist, avoiding excesses and ensuring an effect tailored to the patient’s age and risk.
5. When and how often they should be applied
The frequency depends on age, dietary habits, and cavity history.
- In children: every 6 months, in conjunction with pediatric dentistry.
- In teenagers: 1 to 2 times a year, especially if wearing orthodontic appliances.
- In adults: according to the individual risk assessed during the dental check-up.
The dentist decides the ideal frequency to ensure maximum preventive efficacy.
6. Treatments for children and teenagers
Childhood is the most important phase for creating a lasting oral health foundation.
Dental sealants are applied shortly after the eruption of permanent molars, typically between 6 and 12 years of age. Fluoride therapy, on the other hand, strengthens the natural resistance of the enamel and helps correct the first signs of demineralization.
At OnlySmile, these procedures are integrated into a calm and positive environment, making the experience pleasant for the young ones — an essential complement to Pediatric Dentistry consultations.
7. Fluorotherapy in adults: why it remains important
Many adults believe that fluoride is only for children, but this is not true.
With age, gum recession exposes more vulnerable parts of the tooth — and fluoride helps protect these areas.
Additionally, those with implants, prosthetics, or a history of periodontitis greatly benefit from this reinforcement.
Fluorotherapy reduces sensitivity, strengthens enamel, and prevents cavities in hard-to-reach areas.
8. Step-by-step clinical procedure
- Pre-cleaning of teeth (with brushing and bicarbonate jet).
- Drying and isolation to avoid contact with saliva.
- Application of fluoride or sealant, with brush, syringe, or mold.
- Light curing (for sealants) for immediate hardening.
- Final check and clinical record.
The process takes only a few minutes, and the patient can eat normally after about 30 minutes.
9. Relationship between fluorotherapy and other dental specialties
Fluorotherapy and dental sealants complement other areas of dental medicine:
- Pediatric Dentistry – early prevention of cavities.
- Oral Hygiene – removal of tartar and bacteria before application.
- Orthodontics – additional protection during appliance use.
- Oral Rehabilitation – strengthening natural enamel and adjacent structures.
At OnlySmile, this integration between specialties ensures more lasting and comfortable results for the patient.
