Dental Fillings Lindenhurst NY — Tooth-Colored, Mercury-Free
A cavity left untreated doesn’t stay a cavity. It becomes a root canal. Then a crown. Then maybe a tooth extraction. A simple filling — done early — stops that chain from starting. We use tooth-colored composite resin that matches your natural enamel. No silver. No mercury. Nobody can tell you had it done.

What Is a Dental Filling — And What Happens If I Skip It?
A dental filling restores a tooth damaged by decay (a cavity) back to its normal shape, size, and function. It’s one of the most common dental procedures in the US — and one of the most frequently delayed, because cavities don’t hurt until they’re deep.
That’s the trap. A small cavity costs $150–$300 to fill. Wait until it reaches the nerve and you’re looking at an $800–$1,500 root canal plus a $1,000–$1,800 crown. Wait until the tooth can’t be saved and you need a $3,000–$6,700 implant. The math is brutal — and it’s entirely avoidable.
Why composite resin instead of silver amalgam? Composite bonds directly to the tooth, requiring less healthy tooth removal. It matches your exact shade — completely invisible. It doesn’t expand and contract with temperature the way metal does. And it contains no mercury.
How do I know if I have a cavity?
Most cavities don’t hurt until they’re deep. The only reliable way to detect early decay is a professional exam with X-rays. Sensitivity to cold, sweetness, or biting pressure can signal a cavity — but by then it’s often larger than it would have been at your six-month cleaning.

Your appointment, step by step
Exam & X-rays
We locate the cavity and assess its depth. You see the X-ray. We explain everything before touching a drill.
Numbing
Topical gel first, then a small injection. You feel pressure but not pain. We wait until you’re fully numb.
Decay removal & filling
We remove only the decayed tissue, shade-match the composite resin, place it in layers, and cure each layer with a blue light.
Bite check & polish
We check your bite on articulating paper and polish the surface smooth. Most fillings take 30–60 minutes total.
Common questions
Dental Filling FAQs
Will getting a filling hurt?
No. We numb the area completely before we start. You’ll feel pressure and vibration, but not pain. If you feel anything during the procedure, raise your hand and we’ll add more anesthetic. Most patients are surprised by how comfortable it is.
How long does a composite filling last?
Composite resin fillings typically last 7–10 years with proper care. They may need replacement sooner if you grind your teeth or the filling is in a high-stress area. Silver amalgam fillings can last longer but carry the tradeoffs of mercury content and metal expansion.
My tooth doesn’t hurt. Do I really need a filling?
Yes, if the cavity is confirmed on X-ray. Cavities don’t hurt until they’re deep enough to reach the nerve — by which point you need a root canal, not a filling. Painlessness is not a sign the cavity is fine; it’s a sign you caught it before it became worse.
Does Delta Dental cover composite fillings?
Most Delta Dental PPO plans cover composite fillings at 80% after your annual deductible on back teeth as well as front teeth. Some older plans cover composite only on front teeth and reimburse the amalgam rate on back teeth. We’ll verify your exact benefits before your appointment so there are no surprises.
Can I eat after getting a filling?
Yes, immediately — composite resin hardens fully under the curing light during the procedure. We recommend waiting until the anesthetic wears off (1–2 hours) before eating on that side, since you won’t be able to feel if you’re biting too hard.
How do I know if I have a cavity without coming in?
You often don’t. Early-stage cavities are invisible to the naked eye and cause no pain. That’s exactly why six-month checkups with X-rays exist. Sensitivity to cold or sweets, a visible dark spot, or pain when biting are later warning signs — but most cavities diagnosed at a routine cleaning have no symptoms at all.
