Dental Sealants in Hinsdale, IL
Dental sealants are a quick, painless, and highly effective way to protect teeth from cavities. At Hinsdale Dental Journey, Dr. Alina Huff applies tooth-colored sealants to the deep grooves of back teeth — where over 50% of childhood cavities occur — creating a smooth, protective barrier that keeps food and bacteria out. Sealants are one of the best preventive tools in dentistry, especially for children.
What it is
A thin, tooth-colored plastic coating painted onto the chewing surfaces of back teeth (molars and premolars). It flows into the deep grooves and hardens to form a protective shield against decay.
Who it's for
Primarily children — sealants are applied as soon as permanent molars erupt (around age 6 and again around age 12). Adults with deep grooves or high cavity risk can also benefit.
How we help
Quick, painless application with no drilling or anesthesia needed. We use tooth-colored sealants that are barely visible and can protect teeth for many years with proper care.
Sealants prevent cavities before they start — protect your child's permanent teeth as soon as they erupt.
Why Sealants Are So Effective
- Pits and fissures on the chewing surfaces of molars account for over 50% of cavities in children
- These deep grooves are the perfect environment to trap food and bacteria — and toothbrush bristles are often too wide to clean them
- The enamel in pits and fissures is frequently thinner and weaker, making these areas more vulnerable to decay
- Sealants fill in these grooves and create a smooth, sealed surface that's easy to clean and resistant to bacteria
- Once decay has formed, a sealant can no longer be placed — that's why early application is so important
How Sealants Are Applied
- Clean: The teeth are thoroughly cleaned to remove any plaque or food particles
- Isolate: The teeth are dried and isolated to keep them free from moisture
- Etch: A mild solution is applied to roughen the surface so the sealant bonds effectively
- Rinse and dry: The teeth are rinsed and dried again
- Apply: Liquid sealant is painted into the grooves with a tiny brush — it flows deep into every pit and fissure
- Harden: The sealant is cured with a special light — the entire process takes just minutes per tooth
Timing and Care
When Should Sealants Be Applied?
- First permanent molars (age ~6): These teeth erupt behind the baby teeth and are especially vulnerable — sealants should be placed as soon as they come in
- Second permanent molars (age ~12): Another critical window for sealant protection
- Premolars: May also benefit from sealants depending on the depth of their grooves
- Baby teeth: Occasionally sealed if they have deep grooves and the child is at high risk for cavities
- Dr. Alina Huff carefully examines each tooth before recommending a sealant — timing is key to maximum protection
How Long Do Sealants Last?
- Sealants can protect teeth for many years with proper care
- Dr. Alina Huff checks sealants at every regular visit and can reapply them if they wear down or chip
- Avoid hard foods like ice and hard candy that can crack sealants
- Avoid sticky foods like taffy, caramel, and gummy candy that can pull sealants off
- Sealants protect the chewing surface — but brushing and flossing are still essential to protect between the teeth and along the gum line
The best time to seal teeth is before cavities start — ask about sealants at your child's next visit.

Tips to Prevent Cavities
- Brush at least twice a day for two full minutes with fluoride toothpaste
- Avoid sugary and sticky foods — even healthy snacks like raisins and dried fruit can cause decay if left on teeth
