Dental Sealants
Dental sealants are thin protective coatings placed over the chewing surfaces of molars and premolars to help reduce cavity risk in deep grooves that are difficult to clean.

Understanding dental sealants
Dental sealants are preventive coatings applied to the chewing surfaces of back teeth. Molars and premolars often have deep pits and grooves where plaque and food can collect, even when brushing habits are good.
Sealants flow into these grooves and create a smoother protective surface that is easier to keep clean. They do not cover the entire tooth and are not a substitute for brushing, flossing, fluoride, or regular dental visits.
At Prestwicke Dental, we evaluate cavity risk, tooth anatomy, age, eruption stage, existing decay, and oral hygiene before recommending sealants. They are commonly used for newly erupted permanent molars but may also benefit teenagers and adults with deep, cavity-prone grooves.
Why patients consider this treatment
Potential benefits depend on your diagnosis, treatment goals, and individual oral health.
Helps protect deep grooves on molars and premolars
May reduce the risk of chewing-surface cavities
Requires no drilling when placed on healthy teeth
Usually does not require local anesthesia
Can be completed quickly during a preventive visit
Works alongside fluoride, cleanings, and home care
What to expect
A clear process helps you understand each stage of care.
Evaluation
We examine the tooth surface to confirm that it is healthy and appropriate for sealant placement.
Cleaning
The chewing surface is cleaned and isolated so the sealant can bond properly.
Application
A thin sealant material is placed into the grooves and hardened with a curing light.
Final Check
We check coverage, retention, and bite comfort before the visit is completed.
How we approach dental sealants
Treatment recommendations depend on the diagnosis and condition of the affected teeth and tissues.
Before placing a sealant, we examine the tooth carefully for signs of existing decay, weakened enamel, or restorations. Sealants are designed to protect healthy or selected early-risk surfaces, not to cover untreated cavities.
The tooth is cleaned and kept dry, then a conditioning material is used to prepare the enamel. The sealant is applied in liquid form, allowing it to flow into the grooves before it is hardened with a curing light.
After placement, we check the bite and make sure the sealant fully covers the intended grooves. The material may feel slightly different at first, but most patients adjust quickly.
Sealants are monitored at future dental exams. If part of a sealant wears away or becomes damaged, it can often be repaired or replaced.
Is this treatment right for you?
Dental sealants may be appropriate for patients with deep grooves or elevated cavity risk, especially soon after permanent molars erupt.
You or your child has deep pits and grooves on back teeth.
Permanent molars have recently erupted and are still cavity-free.
The patient has a history of cavities or higher decay risk.
Brushing alone is not fully cleaning deep chewing-surface grooves.
The teeth do not already have large fillings or active decay in the areas being sealed.
What results may look like
Dental sealants create a thin protective barrier over cavity-prone grooves, helping make chewing surfaces easier to keep clean. Their condition should be checked during routine exams because they may wear, chip, or need repair over time.
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. Sealants are most commonly recommended for children and teenagers, but some adults with deep grooves or higher cavity risk may also benefit.
Do dental sealants hurt?
No. Sealant placement is usually comfortable and does not involve drilling or local anesthesia when placed on healthy teeth.
How long do dental sealants last?
Sealants may last for several years, but longevity varies with bite forces, wear, tooth position, and habits. They should be checked during routine dental exams.
Can a tooth still get a cavity after a sealant is placed?
Yes. Sealants reduce risk on the protected chewing surface but do not make a tooth cavity-proof. Decay can still develop on other surfaces or if the sealant becomes damaged.
Do sealants replace fluoride?
No. Sealants protect deep grooves, while fluoride helps strengthen enamel more broadly. They are often used together as part of a prevention plan.
Do sealants replace brushing and flossing?
No. Daily brushing, flossing, a balanced diet, and routine dental visits remain essential even when sealants are present.
Can sealants be placed over early decay?
That depends on the condition of the tooth. Some very early non-cavitated areas may be managed conservatively, but active cavities usually require different treatment.
How soon after molars erupt should sealants be considered?
Sealants are often most useful soon after permanent molars erupt, when the grooves are deep and the teeth are still cavity-free.
