Quick Facts
Essential information about this procedure
“A 20-minute preventive visit today is worth more than a 90-minute restorative one next year.”
Why Prevention Beats Fixing Problems Later
If you've ever been told you need a filling and thought, how did that happen? — you're not alone. Cavities don't announce themselves. They quietly form in the deep grooves of your back teeth, where a toothbrush can't quite reach, until one day they show up on an X-ray.
That's exactly what sealants are designed to prevent. Dr. Deshpande applies a thin, clear coating to the chewing surfaces of your molars — the teeth most vulnerable to decay — that physically blocks food and bacteria from settling in. It takes minutes, it doesn't require any drilling or numbing, and it's one of the smartest investments you can make in a tooth that's meant to last a lifetime.
Professional fluoride works differently but toward the same goal. The fluoride applied here at Brilliant Smiles is a concentrated formula that bonds directly to your enamel and makes it harder for acid to do damage. Your toothpaste helps maintain fluoride levels day to day, but in-office treatment rebuilds enamel in a way that brushing simply can't replicate.
We recommend both for kids as soon as their permanent molars come in — and for adults who are cavity-prone, have dry mouth, or just want to be proactive. There's no age limit on protecting your teeth.
What to Expect at Your Visit
From the moment you arrive to long-term protection — here's how it works.
At Your Visit
Cleaning & Exam First
Sealants and fluoride are applied after your teeth have been cleaned and dried — no extra appointment necessary in most cases.
Minutes Later
Sealant Application
Dr. Deshpande or her team paints the sealant onto your back teeth, lets it bond under a quick light, and you're done — no numbness, no recovery time.
Same Visit
Fluoride Treatment
A concentrated fluoride varnish or gel is applied to all tooth surfaces — it sets fast and keeps working over the next several hours.
Ongoing
Protection That Lasts
Your sealants are checked at every routine visit and touched up if needed; most patients go years without a new cavity in treated teeth.

How a Sealant & Fluoride Visit Works
The whole process fits inside a routine cleaning appointment — Dr. Deshpande walks you through each step so nothing feels unexpected.
Teeth Are Cleaned & Dried
Before anything is applied, your teeth are polished and thoroughly dried so the sealant material bonds properly to the enamel surface.
Sealant Is Painted On
A thin liquid coating is brushed into the grooves of your back teeth and hardened with a small curing light — the whole step takes just a few minutes per tooth.
Fluoride Seals the Session
A professional-strength fluoride varnish is applied to all your teeth, sets quickly, and continues strengthening your enamel for hours after you leave.

Learn moreQuestions We Hear About Sealants & Fluoride
Are sealants and fluoride just for kids, or do adults benefit too?
Both can be genuinely useful for adults, depending on your cavity history and the anatomy of your teeth. Sealants are most commonly placed on children's molars, but adults with deep grooves in their back teeth can benefit from them too. Fluoride treatments are regularly recommended for adults who have a higher cavity risk, dry mouth, or are going through changes in their diet or health that affect their teeth.
Is fluoride safe to use at the dental office?
Yes — professional fluoride treatments use a higher concentration than toothpaste, but they're applied in a controlled way and are completely safe. The fluoride is left on for a few minutes and strengthens the outer layer of the tooth to make it more resistant to acid and decay. It's one of the simplest, most evidence-backed tools in preventive dentistry.
How are sealants applied, and does it hurt?
Not at all — it's one of the easiest things we do. The tooth is cleaned and dried, a thin liquid resin is painted into the grooves, and then it's hardened with a curing light. The whole process takes just a few minutes per tooth, there's no drilling involved, and most kids barely notice it's happening.
How long do sealants last?
Sealants typically last 5 to 10 years with normal wear. Dr. Deshpande checks them at every exam to make sure they're intact and doing their job — if one chips or wears down, it can easily be reapplied. They're one of the most cost-effective ways to prevent cavities, especially in kids whose back teeth are most vulnerable.
Does insurance cover sealants and fluoride?
For children, sealants and fluoride are covered by most major dental plans — often at 100% as a preventive benefit. Adult coverage for fluoride varies by plan. We accept most major insurance plans and will check your specific benefits so you know before the appointment what's covered.
The patients I worry about most aren't the ones with cavities — they're the ones who are one bad checkup away from needing one. Sealants and fluoride are how we make sure that checkup never comes.

Stop Cavities Before They Ever Start
Sealants and fluoride can be added to your next cleaning appointment — no extra visit, no downtime, no discomfort.
When you come in, Dr. Deshpande will evaluate which teeth are most at risk, explain exactly what she recommends and why, and take care of everything in one comfortable visit. Most major dental plans cover preventive treatments, and her team will confirm your benefits ahead of time.
