Dental sealants are thin protective coatings placed over the chewing surfaces of back teeth. These teeth often have deep pits and grooves where food particles and cavity-causing bacteria can collect, even with regular brushing.


Sealants flow into these hard-to-clean areas and harden, creating a protective barrier over the enamel. They are commonly recommended for children and teens as their permanent molars emerge, but adults with healthy, cavity-prone teeth may also benefit. Dental sealants may be recommended for:


  • Permanent molars with deep pits and grooves
  • Teeth that are difficult to clean thoroughly
  • Children or teens with an increased risk of cavities
  • Early areas of enamel decay, when appropriate
  • Adults with cavity-prone back teeth


Our dentists will examine your teeth and assess your risk of cavities to determine whether sealants are a suitable preventive option.

Adding Cavity Protection With Our Local Dentist

Applying dental sealants is a straightforward and comfortable process. The tooth is first cleaned and dried before a conditioning solution is placed on the chewing surface. The sealant material is then applied and hardened, often with a special curing light.


No drilling or removal of healthy tooth structure is usually needed. Once the sealant is set, your dentist checks the tooth and bite to ensure a comfortable result. Patients can generally return to their usual activities immediately after the appointment.


Sealants can provide protection for several years, but they may gradually wear or become damaged. During routine dental visits, our team checks their condition and can repair or reapply them when needed. Brushing, flossing, and regular dental care remain essential for protecting every surface of the teeth.

Find answers to common questions about dental sealants at Palo Alto Central Dental.

  • Who can benefit from dental sealants?

    Sealants are often recommended for children and teens after their permanent molars emerge. Adults with deep grooves in healthy back teeth may also benefit, depending on their dental history and risk of developing cavities.

  • How are dental sealants applied?

    The tooth is cleaned, dried, and prepared with a conditioning solution. A thin layer of sealant material is then painted onto the chewing surface and hardened, often using a special light, to form a protective barrier.

  • Does getting dental sealants hurt?

    Applying dental sealants is generally comfortable because the procedure does not usually require drilling or removing tooth structure. Patients may notice the new coating briefly, but the bite should feel natural after placement.

  • How long do dental sealants last?

    Dental sealants can protect teeth for several years, although they may gradually wear or become damaged. During routine visits, our dentists will check their condition and recommend repair or reapplication when needed.

  • Do sealants replace brushing and flossing?

    No. Sealants protect the chewing surfaces of selected teeth, but they do not cover every area of the mouth. Brushing twice daily, flossing, healthy food choices, and regular dental visits remain important.
