Dental Sealants
Dental sealants are thin protective coatings placed in cavity-prone pits and grooves of back teeth to help prevent decay and protect selected early non-cavitated areas.

A quick overview before exploring the treatment in greater detail.
Thin protective coating for cavity-prone back teeth
May benefit children, teens, and selected adults
Conservative placement usually completed without drilling or anesthesia
Understanding dental sealants
Molars and premolars often have narrow pits and grooves where plaque and food can collect, even when brushing habits are good. Dental sealants are thin protective coatings placed on these chewing surfaces to keep bacteria and food particles from settling into susceptible areas.
Sealant material flows into the grooves and hardens, creating a smoother barrier that is easier to keep clean. Sealants do not cover the entire tooth and do not make teeth cavity-proof. Brushing with fluoride toothpaste, cleaning between teeth, a balanced diet, and regular dental visits remain essential.
At Prestwicke Dental, we evaluate cavity risk, tooth anatomy, eruption stage, ability to keep the tooth dry, existing restorations, and whether a surface is sound, non-cavitated, or already structurally damaged. Sealants are frequently used on newly erupted permanent molars, but selected primary teeth, premolars, teenagers' teeth, and adult teeth may also benefit.
Why patients consider this treatment
Potential benefits depend on your diagnosis, treatment goals, and individual oral health.
Protects susceptible pits and grooves on back teeth
Reduces the risk of decay on covered chewing surfaces
May help arrest selected early non-cavitated pit-and-fissure lesions
Usually requires no drilling when placed preventively
Can often be completed during a preventive visit
Works alongside fluoride and daily home care
What to expect
A clear process helps you understand each stage of care.
Tooth Evaluation
We examine the grooves and determine whether the surface is appropriate for a sealant or needs another form of care.
Cleaning and Isolation
The tooth is cleaned and kept dry so the sealant material can form a reliable bond with the enamel.
Sealant Placement
The enamel is prepared, sealant flows into the selected grooves, and the material is hardened according to the product used.
Final Check
We examine coverage and retention, check the bite, and document the sealant for monitoring at future visits.
How we approach dental sealants
Treatment recommendations depend on the diagnosis and condition of the affected teeth and tissues.
Before recommending a sealant, we examine the tooth for enamel breakdown, cavitation, existing restorations, and signs that decay may extend beyond the area that can be managed with a sealant. Sound grooves and selected early non-cavitated lesions may be appropriate; established cavities with structural loss usually require another treatment.
Successful bonding requires a clean, dry surface. The tooth is isolated, cleaned, and conditioned to create microscopic surface texture. The conditioning material is rinsed away, the tooth is dried, and sealant is flowed carefully into the intended pits and grooves.
Most resin-based sealants are hardened with a curing light. Depending on the clinical situation, tooth eruption, moisture control, and material selected, the exact technique may vary. The procedure is usually comfortable and does not require local anesthesia when no drilling is needed.
After placement, we verify that the material covers the intended anatomy and check how the teeth come together. The sealant may feel slightly different at first, but the bite should remain comfortable.
Sealants can last for years, but they are not permanent. Normal chewing, tooth grinding, hard foods, or partial loss of bonding can wear or chip the material. At routine exams, we check retention and can repair or replace a sealant when clinically appropriate.
Is this treatment right for you?
Dental sealants may be appropriate for primary or permanent teeth with deep pits and grooves, especially when anatomy, eruption stage, or cavity history creates elevated risk.
Your child has newly erupted permanent molars with deep grooves.
A primary molar has cavity-prone anatomy and is expected to remain for several years.
You or your child has a history of cavities or elevated decay risk.
The chewing surface has a selected early non-cavitated area that may be managed conservatively.
The tooth does not have a large restoration or a cavitated lesion requiring a different treatment.
What results may look like
Dental sealants create a protective barrier over selected pits and grooves, reducing exposure to food particles and cavity-causing bacteria on the covered surface. Their protective value depends on retention, so sealants are checked during future exams and repaired or replaced when necessary.
Individual outcomes vary based on oral health, diagnosis, treatment selection, healing, habits, and maintenance.

Common questions about dental sealants
These answers provide general information. Your visit will address your specific oral health and treatment needs.
Are dental sealants only for children?
No. Children and teenagers are common candidates because newly erupted molars are vulnerable, but selected adults with deep grooves, no cavitation, and elevated cavity risk may also benefit.
Do dental sealants hurt?
Sealant placement is usually comfortable. When placed on an appropriate surface, it generally does not require drilling, injections, or local anesthesia.
How long do dental sealants last?
Sealants often protect teeth for several years, but retention varies with bite forces, tooth position, moisture control during placement, habits, and material wear. They should be checked during routine exams.
Can a tooth still develop a cavity after being sealed?
Yes. A sealant lowers risk only on the surface it covers. Decay can develop on other tooth surfaces or beneath an area where the sealant has been lost, so home care and regular examinations remain important.
Do sealants replace fluoride, brushing, or flossing?
No. Sealants protect selected pits and grooves, while fluoride supports exposed enamel surfaces. Brushing twice daily, cleaning between teeth, healthy food and drink choices, and preventive visits are still necessary.
Can sealants be placed over early tooth decay?
Selected non-cavitated pit-and-fissure lesions may be managed with a properly bonded and monitored sealant. A cavitated lesion or decay with structural breakdown usually requires a different treatment. The tooth must be examined first.
Are dental sealant materials safe?
Dental sealants have a long history of clinical use and are applied in small, controlled amounts. Tell us about any known material allergies or previous reactions so we can select care appropriately and answer product-specific questions.
When should sealants be considered for permanent molars?
First permanent molars commonly erupt around age six and second molars around age twelve, although timing varies. Evaluation soon after enough of the chewing surface has erupted allows us to assess anatomy, cavity risk, and whether reliable isolation is possible.
