The Pros and Cons of Dental Sealants

October 1, 2023


When it comes to maintaining optimal dental health, preventive measures are key. Dental sealants are one such preventive tool that has recently gained popularity. In this article, we will learn what dental sealants are, who can benefit from them, and the advantages and disadvantages they offer. Whether you’re a seasoned dental patient or just someone curious about dental care, understanding the ins and outs of dental sealants can be beneficial.

What are Dental Sealants?

Dental sealants are thin and protective coatings applied to the chewing surfaces of mouth molars and premolars. These teeth are located at the back of your mouth and are more susceptible to cavities due to their deep grooves and fissures. Sealants act as a hurdle, preventing food particles and bacteria from settling into these crevices and causing decay.

The Application Process

Having dental sealants applied is a quick and painless procedure. First, the teeth must be sealed, thoroughly cleaned, and dried. Next, a special gel is applied to roughen the surface of the teeth, which helps the sealant adhere better. After rinsing off the gel and drying the teeth again, the sealant material is carefully painted onto the tooth’s surface. Sometimes, a curing light may harden the sealant and ensure it bonds securely.

Who Should Consider Dental Sealants?

  1. Children and Adolescents: Dental sealants in New York, NY, are highly recommended for children and teenagers as soon as their molars erupt. Since these are the formative years for oral health, protecting their permanent teeth from the start can prevent future dental issues.
  2. High Risk of Cavities: Individuals with a history of cavities or deep grooves in their teeth are prime candidates for dental sealants. Sealants provide an extra layer of defense against cavity-causing factors.
  3. Orthodontic Patients: Orthodontists near you may find it challenging to clean around braces. Sealants can make cleaning easier and protect teeth during this period.

The Pros of Dental Sealants

  1. Effective Cavity Protection: Dental sealants offer a high level of protection against cavities, significantly reducing the risk of tooth decay.
  2. Cost-Effective: Sealants are a cost-effective preventive measure compared to the expenses of treating cavities and other dental problems.
  3. Painless and Non-Invasive: Applying dental sealants is simple and painless, making it an easy choice for children and adults.
  4. Long-Lasting: Sealants can last many years with proper oral hygiene and regular dental check-ups, providing extended protection.
  5. Improved Oral Health: By preventing cavities and tooth decay, sealants improve oral health, reducing dental visits for fillings and treatments.

The Cons of Dental Sealants

  1. Limited Protection: Sealants are highly effective on chewing surfaces but do not offer complete protection against cavities. Proper oral hygiene, including brushing, flossing, and regular dental visits, is still essential.
  2. Reapplication May Be Required: Sealants can wear down or chip over time, necessitating reapplication. However, regular dental check-ups will help identify any issues early on.
  3. Allergic Reactions: Although rare, some individuals may be allergic to the materials used in dental sealants. It would help to inform your pediatric dentist in the Upper East Side of any known allergies beforehand.
  4. Timing of Application: The ideal time to apply dental sealants is soon after the eruption of permanent molars. If they are not applied at the right time, the teeth may already have some degree of decay.
  5. Not a Substitute for Oral Hygiene: Dental sealants should not be considered a replacement for regular oral hygiene practices. Proper brushing, flossing, and maintaining a healthy diet are still essential to oral health. Sealants complement these practices but still need to eliminate the need for them.


Dental sealants can be a valuable tool in the fight against cavities and tooth decay, especially for children and individuals at high risk of developing oral issues. Their ability to provide long-lasting protection and a relatively painless application process makes them an attractive option for many dental patients.

Remember, dental sealants are just one part of maintaining good oral hygiene. Regular brushing, flossing, and dental check-ups are equally important. If you’re considering dental sealants for yourself or your child, consult your dentist to determine if they are the right choice for your dental needs.
