Preventive Dentistry Practices

  2. Preventive Dentistry Practices

Preventive dentistry includes practices aimed at preventing the most common oral and dental diseases, such as tooth decay and gum inflammation, before they occur.

The main practices include:

  • Promoting proper nutrition and dietary habits

  • Encouraging regular tooth brushing and flossing habits

  • Application of fluoride preparations

  • Periodic dental check-ups every 6 months

  • Assessment of the individual’s risk for tooth decay

  • Evaluation of oral and dental growth and development

  • Providing oral health education

  • Application of fissure sealants

  • Use of space maintainers in children

Fissure Sealant Applications (Preventive Treatments to Avoid Tooth Decay)

The grooves and pits on the surfaces of teeth provide an ideal environment for food debris and bacteria to accumulate. Covering these surfaces with a filling-like material (fissure sealant) without removing or wearing down any part of the tooth, creating a transparent protective layer (like walking in the rain with an umbrella), is a highly effective preventive measure (70–80% protection) against potential tooth decay.

Fluoride-containing gels are applied to children by a pediatric dentist. This application makes the teeth more resistant to cavities.

It is recommended that children receive fluoride and fissure sealant treatments starting from the age of 6.

Fissure Sealant Applications

Fissure sealants are a flowable material that covers the chewing surfaces of teeth, protecting them against decay. Research indicates that 90% of tooth decay begins in the small, deep, and narrow grooves (fissures) on the chewing surfaces of molars. Since newly erupted teeth are not fully mineralized (hardened), they are more susceptible to decay. For this reason, it is recommended that fissure sealants be applied shortly after the teeth have erupted. Studies show that fissure sealant applications can prevent 85–90% of tooth decay.

Fluoride Treatment

Another important preventive measure is fluoride application. Both primary (baby) and permanent teeth act like a sponge, absorbing both beneficial and harmful substances until around age 15, when the teeth are fully mature. Fluoride treatments applied during this period not only prevent tooth decay but also integrate into the tooth structure, protecting it from external factors for a longer time, more effectively than typical filling materials.
