The deep grooves on back teeth can trap food and bacteria even when you brush carefully. Dental sealants in Las Vegas, NV, add a protective barrier over these vulnerable chewing surfaces, helping reduce the risk of cavities before decay has an opportunity to develop.
At Preferred Family Dentistry, Dr. Salmeh Jafarifar provides dental sealants for children, teenagers and qualifying adults. Application is quick and noninvasive, with no drilling or removal of healthy tooth structure required.
Call 702-433-0355 today to learn whether dental sealants could provide added cavity protection for you or your child.
What Are Dental Sealants?
Dental sealants are thin coatings applied to the chewing surfaces of molars and premolars. These back teeth often have narrow pits and grooves that can be difficult for toothbrush bristles to clean thoroughly.
When plaque and food remain in these areas, bacteria can produce acids that weaken the enamel and contribute to cavities. Sealant material flows into the grooves and hardens, creating a smoother surface that is easier to keep clean.
Sealants are generally clear, white or tooth-colored, so they are not highly noticeable when you speak or smile. They do not cover the entire tooth or change how the tooth normally functions.
How Dental Sealants Help Prevent Cavities
Brushing and flossing remain essential, but even excellent home care may not fully clean every narrow groove in a back tooth. Sealants provide additional protection by creating a physical barrier between the enamel and cavity-causing bacteria.
Dental sealants may help:
- Protect cavity-prone grooves on back teeth
- Keep food and plaque from settling into deep pits
- Make treated chewing surfaces easier to clean
- Preserve healthy tooth enamel
- Reduce the likelihood of needing fillings in sealed areas
- Support a broader preventive dental care plan
A sealant cannot guarantee that a tooth will never develop decay. Cavities may still form between teeth, near the gumline or in areas where the sealant has worn away. Regular brushing, flossing, dental exams and professional cleanings remain important.
Which Teeth Can Be Sealed?
Sealants are most commonly applied to permanent molars because their chewing surfaces tend to have the deepest grooves. Premolars or other teeth may also benefit when their anatomy makes them difficult to clean.
Dr. Jafarifar will examine each tooth before recommending treatment. A sealant is generally placed only when the surface is healthy enough to be protected effectively.
Sealants are not used to repair a large cavity, broken tooth or severely damaged restoration. If decay is already present, treatment such as a composite dental filling may be needed instead.
Dental Sealants for Children and Teenagers
Children and teenagers may be especially vulnerable to cavities as permanent molars emerge and they continue developing consistent brushing habits. The grooves in newly erupted back teeth can collect plaque before a child becomes skilled at cleaning them thoroughly.
Applying sealants soon after qualifying permanent molars appear can help protect the enamel during these cavity-prone years. The appropriate timing varies because every child’s teeth develop at a different pace.
Sealants may be particularly helpful for a child or teenager who:
- Has deep grooves in the back teeth
- Has difficulty brushing molars thoroughly
- Has experienced previous cavities
- Frequently develops plaque buildup
- Consumes sugary or acidic snacks and drinks regularly
- Would benefit from additional preventive protection
Our team explains the process in age-appropriate language and allows children to know what to expect before treatment begins.
Can Adults Get Dental Sealants?
Sealants are not limited to children. Adults with healthy molars, deep grooves and no existing restorations on the intended surfaces may also benefit.
An adult may be considered for sealants if:
- The chewing surfaces remain free of significant decay
- The teeth have deep pits that collect food or plaque
- The area is difficult to clean despite regular brushing
- The patient has an elevated risk of developing cavities
Many adult molars already have fillings, crowns or areas of wear, so treatment must be evaluated individually. Dr. Jafarifar will determine whether a sealant, fluoride treatment, filling or another preventive option is appropriate.
What Happens During Dental Sealant Application?
Applying a dental sealant is typically straightforward and does not require drilling or numbing. Several teeth may be treated during the same appointment when appropriate.
The process generally includes:
- Cleaning the tooth: Plaque and debris are removed from the chewing surface.
- Keeping the area dry: The tooth is isolated so saliva does not interfere with bonding.
- Preparing the enamel: A conditioning material is placed briefly to help the sealant attach securely.
- Rinsing and drying: The surface is prepared for the sealant material.
- Applying the sealant: The liquid material is brushed into the pits and grooves.
- Hardening the material: A curing light may be used to set the sealant.
- Checking the bite: Dr. Jafarifar confirms that the treated tooth feels comfortable when you close your mouth.
You can generally speak and chew normally after the material has hardened. The tooth may feel slightly different at first because its previously deep grooves now have a smoother surface.
Do Dental Sealants Hurt?
Sealant application is noninvasive and should not be painful. Healthy tooth structure is not drilled away, and local anesthesia is generally unnecessary.
The tooth must remain clean and dry while the material is placed, but the treatment itself is brief. Let our team know if your child feels nervous or has difficulty sitting through dental care so we can explain each step and help make the visit more comfortable.
Are Dental Sealants Safe?
Dental sealants have been widely used as a preventive treatment for children, teenagers and adults. Dr. Jafarifar will first examine the tooth and review any relevant health information to determine whether application is appropriate.
The material is applied only to the tooth’s outer chewing surface. Once hardened, it forms a thin protective layer over the enamel.
Parents and patients are encouraged to ask questions about the materials, procedure or recommended care before deciding to move forward.
How Long Do Dental Sealants Last?
Sealants can provide protection for years, but they are exposed to daily chewing pressure and may gradually wear, chip or loosen. Their lifespan varies based on the tooth, bite, diet, oral habits and material condition.
During routine dental exams, Dr. Jafarifar can check whether the sealant remains intact. A worn area may sometimes be repaired or recoated when the tooth is still healthy.
Sealants should not be considered permanent or ignored after placement. Continued monitoring ensures that the tooth remains protected and that early decay is not developing around a damaged sealant.
Dental Sealants vs. Fluoride Treatment
Dental sealants and fluoride treatment both help prevent cavities, but they protect teeth in different ways.
Dental Sealants
Sealants create a physical barrier over pits and grooves on selected chewing surfaces. They are especially useful for molars that trap plaque and food.
Fluoride Treatment
Fluoride helps strengthen enamel and make teeth more resistant to acid attacks. It can benefit broader tooth surfaces rather than covering individual grooves.
Some patients may benefit from both treatments as part of a personalized preventive plan. Dr. Jafarifar will recommend care based on age, cavity history, enamel health and individual risk factors.
Dental Sealants vs. Composite Fillings
A dental sealant helps protect a healthy or cavity-prone surface before significant decay develops. A filling repairs a tooth after decay or damage has already removed part of the enamel.
If Dr. Jafarifar finds a cavity during the examination, covering it with a preventive sealant alone may not be appropriate. The decayed portion may need to be removed and restored with a tooth-colored filling.
Regular preventive visits give our team an opportunity to recommend sealants while teeth are still healthy enough to benefit from them.
How to Care for Teeth With Sealants
Sealants do not require a complicated care routine. Treated teeth should be brushed and cleaned just like the rest of your smile.
To help protect sealed teeth:
- Brush twice daily with fluoride toothpaste
- Floss or clean between the teeth every day
- Limit frequent sugary and acidic snacks or drinks
- Avoid chewing ice and other extremely hard objects
- Keep regular dental exams and professional cleanings
- Tell our team if the tooth feels rough or the bite feels different
Professional teeth cleaning also helps control plaque around the areas that sealants do not cover.

FAQ About Dental Sealants
At what age should children get dental sealants?
Sealants are often considered after permanent molars emerge, but the right timing depends on the child’s dental development and cavity risk. Dr. Jafarifar will examine the teeth and recommend treatment when appropriate.
Are dental sealants only for children?
No. Teenagers and adults may also benefit when they have healthy back teeth with deep grooves that are vulnerable to decay.
Does applying a dental sealant hurt?
No drilling or numbing is generally required. The tooth is cleaned, prepared and coated with sealant material, making the process noninvasive and typically comfortable.
Can you see dental sealants on the teeth?
Sealants are usually clear, white or tooth-colored. Because they are placed mainly on the chewing surfaces of back teeth, they are not highly visible when you smile.
Can a sealant be placed over a cavity?
Sealants are intended primarily to protect suitable tooth surfaces from decay. If a cavity is present, Dr. Jafarifar will determine whether a filling or another treatment is needed.
How long do dental sealants last?
Sealants may remain effective for years, but they can wear or chip. Our team will check them during routine exams and recommend repair or reapplication when appropriate.
Does my child still need to brush after getting sealants?
Yes. Sealants protect only selected chewing surfaces. Brushing, flossing, healthy eating habits and regular dental visits are still necessary to protect the rest of the teeth.
Are dental sealants the same as fluoride?
No. Sealants form a protective barrier over deep grooves, while fluoride strengthens enamel. The treatments may be used together when both are appropriate.
